Three well-known companies took part in the creation of the Nissan Almera G15 car at once - Nissan, Renault and AvtoVAZ. Manufacturers expected that the brand of the largest Japanese company will attract the attention of buyers, and they will be willing to purchase such a budget foreign car. This marketing ploy has done its job, hunters for inexpensive car found a lot - good quality Russian assembly and components raised to a decent level.

power unit

The Almera engine is nothing more than the Renault K4M engine, developed by French engineers back in 1999 and is the only option power plant for this car. Powered by AI-92 gasoline, four-stroke, has two camshafts and sixteen valves. Four cylinders of the engine are located in one row and develop a power of 102 hp. With.

The K4M motor with a gearbox and clutch make up a single power unit with a three-point mount engine compartment on metal-rubber supports. The cylinder group is placed in a cast-iron block; a block head made of aluminum alloys is attached to the top with ten bolts.

In the cylinder head (cylinder head) for each cylinder there are four valves - two for the outlet and two for the intake with hydraulic compensators that automatically adjust the gaps between the valve and the camshaft. Two camshafts are located at the top of the head, one of them works with exhaust valves - the other with inlet ones. This gas distribution mechanism is a classic DONS system.

The timing system has a belt drive and is the weakest link, because getting oil on the belt or its slightest delamination leads to a belt break and an inevitable meeting of the pistons with valves and further costly repairs.

To prevent this, it is necessary to change the belt drive strictly within the time limits specified in the operating instructions or in case of oiling the belt and if the fabric base is damaged.

Nissan Almera G15 engine has injection system power supply, which is based on electronics that directly controls the injection and distribution of fuel to the injectors.

unpretentious and reliable motor K4M is designed for a mileage of 400 thousand km, but in practice the engine life is much longer.

Transmission Nissan Almera G15

In the Russian assembly, the Almera engine is equipped with a manual 5-speed gearbox or a four-speed automatic. The manual box is far from being a new development for Renault cars, but with rather frisky dynamics, it accelerates to a hundred kilometers in 10.9 seconds, which is not bad at all for a car weighing 1.2 tons.

A reliable and well-assembled manual transmission rarely breaks down and a mileage of 200 thousand km is not a problem for it. Despite the manufacturer's statement about the uselessness of changing the oil for the entire service life, for Russian roads it is recommended to change the oil after 75 thousand km.

The automatic transmission on the Nissan Almere is the same for Renault Clio, it, like all automatic transmissions, does not keep up with the gas pedal, the reaction with a clear slowdown, acceleration to a speed of 100 km / h occurs in 12.7 seconds. automatic box does not tolerate overheating and often fails because of this, but its repair is simple.

Fuel consumption with an automatic, especially with the air conditioner on, is about 13 liters in the urban cycle, but this is understandable - you have to pay for comfort.

Refinement of the K4M engine

The Nissan Almera motor is a solid and reliable unit, but it has one weakness, it lacks power at low initial speeds. When working on bottoms, it burns a lot of fuel. Gadgetman Technologies technology comes to the rescue and the essence of the work performed is as follows: metal is selected near the engine throttle and special grooves of a special shape are cut, which increase turbulence and change the physical nature of the air flow.

On an unfinished throttle, fuel particles do not burn out, but simply fly away into exhaust system. The applied technological grooves on the throttle create such pressure drops that the fuel mixture goes into a state of steam and burns out completely. Accordingly, traction at low speeds increases, and complete combustion of the mixture guarantees a reduction in fuel consumption.

How did you come up with this?

I didn't invent the technology. I'm just the owner of the copyright license. And I bring technology to mind.

How long have you been doing this?

tenth year I professionally improve the performance of cars with the help of machining throttle. I do not deceive anyone and I do not run from anyone. To deceive people is not my specialty, and to deceive is dearer to me. I give a guarantee for my work. The described changes in the cars are recorded from the words of customers.

What cars are throttle body modifications done on?

Refinement of the throttle is done on gasoline (injection, carburetor) engines. On the diesel engines we use other technologies.

How much will the engine power increase after the throttle is finalized?

The engine produces maximum power for high revs 4000-7000 rpm depending on the engine. This is exactly what you have in your documents. At low and medium speeds, the engine does not produce maximum power. I use this technology to increase power at low speeds and partly at medium speeds. And this figure does not affect the maximum engine power. Therefore, the horses remain, and traction at low speeds increases.

How refinement of the throttle can affect the life of the engine?

Positively! The less fuel is burned, the less carbon deposits and coking of pistons are formed and piston rings. The absence of soot does not entail other resulting problems with the engine. It also extends the life of the auto catalyst, if it is still available. Because unburned gasoline does not burn out in the catalyst. Once you've tweaked the throttle, you'll start riding at lower RPMs. Less RPM reduces wear on moving engine parts. Thus, the motor resource of the engine is increased.

Why do manufacturers not immediately make a refinement of the throttle?

And why do manufacturers not immediately do what the market offers to improve cars ?!

First, the technology is young. Secondly, the manufacturer puts in the car what the market offers. The lion's share of the electrical market is occupied by Bosch. Therefore, this refinement should be done by Bosch. Thirdly, there is information that this technology was bought by Toyota and BMW. It is possible that new models of cars from these manufacturers will already have this refinement.

Model Nissan Almera debuted in 1995 and replaced the Nissan Sunny on the assembly line. She lasted on the assembly line for 5 years, having survived one restyling in 1998. In 2000, it was replaced by the second generation Almera. Both generations had, though not very extensive, but a sufficient choice of engines. Also, their characteristic feature was the high level of equipment, even the basic versions.

In 2006, the second generation was replaced by Almera Classic, but it was not direct evolution. At its core, the model was a converted version of the Korean Samsung SM3. The platform and the main components and assemblies were “shared” by colleagues from the concern from Renault.

In 2012, the BO platform developed by the French came in handy once again. Developed on its basis, the Almera G15 entered the market.

Almera N15 (1995-2000)

The range of power units was represented by three petrol and two diesel engines.

Petrol

• 1.4 l. (87 hp);
• 1.6 l. (99 hp);
• 2.0 l. GTI (147 hp).

All installed engines were sixteen-valve fours with a fuel injection system. They are characterized as quite economical, but rather weak on low revs. In order to achieve pickup, it is necessary to spin them up to 3000 rpm and above. common feature of all gasoline engines is the timing drive. Here it is a chain with a hydraulic tensioner. On the one hand, owners may not worry about replacing the timing drive for a long time, compared to owners of a belt-driven motor. But at the same time, it is worth remembering the age of the model and carefully monitoring the condition of the chain and tensioner. It is also necessary to monitor the condition of the thermal clearances of the valves. The adjustment is made with washers, and the manufacturer recommends performing the procedure every 40 thousand km.

The entire line of gasoline engines has established itself as reliable and durable. With high-quality and timely maintenance, the total resource should be at least 300 thousand km, but it is not uncommon for engines to run more than 400 thousand. However, this is true when using quality oil. These motors are very sensitive to this indicator. Failure to comply with the recommendations leads to the appearance of leaks at the seals and gaskets to 150-200 thousand km. Owners who save on air filter replacement may have problems with the sensor mass flow air (DMRV). There are cases of "floating" speed, as a result of problems with the regulator idle move. Also, the masters note problems with the tightness of the cooling system and oil leakage through the pressure sensor.

Diesel

• 2.0 l. D (75 hp);
• 2.0 l. TD (90 hp).

Heavy fuel units have a timing belt drive, so owners will have to more often and more carefully monitor the condition of the mechanism. The consequences of a break are fraught with serious costly repairs.

The main problem with diesel units is the fear of motors overheating. Owners should monitor the temperature condition very carefully. Otherwise, costly repairs or even replacement of the entire cylinder head will be required. Yes and if temperature regime observed correctly, then for many instances, by 200 thousand km, a serious cylinder head repair is required.

HPFP is sensitive to quality diesel fuel, and just like gasoline diesel units require the use of high-quality oil.

Almera N16 (2000-2006) Petrol range

• 1.5 l. (90/98 hp);
• 1.8 l. (114/116 hp).

Former reliable units were replaced by more powerful ones. It's not that they're too much trouble, but fans of the model have often noted that reliability has dropped markedly compared to the previous generation. Most likely this is a consequence of an increase in the level of manufacturability, which is accompanied by a complication of the design. So, after modernization, the engines received new system with variable valve timing NVCS (Nissan Valve Timing Control System).

The younger motor is characterized by problems with stretching the timing chain. This is expressed in traction dips, hard start, "floating" idling. It is possible to get rid of the problem by replacing the stretched chain. Also, sometimes the problem of starting not the first time manifests itself. Most often this indicates dirt in throttle or contamination of the fuel pump screen. In extreme cases, the fuel pump may need to be replaced. Twitching at low speeds is treated with a firmware update.

A larger 1.8-liter unit has the property of high oil consumption. There are frequent cases of consumption of 1 liter. per 100 km, sometimes even more. This is due to the poor quality of the piston rings. In the case of an increase in consumption to 0.5 l. at 100 km and above, it is recommended to contact the service for repairs. It should be prepared that the procedure will be quite expensive.

The timing chain is also not durable. Already after 150 thousand km, characteristic symptoms may appear, after which it will be necessary to think about replacing it. Trouble can be caused by the loss of tightness of the idle valve gasket. Typical faults there are also failures of the flow meter, crankshaft position sensor and lambda probe.

Despite the existing problem areas, engines in general have a decent resource. With quality service, they calmly nurse up to 250-300 thousand km before overhaul.

Diesel units

• 1.5 l. DCi (82 hp);
• 2.2 l. Di (110 hp);
• 2.2 l. DCi (112/136 hp).

Nissan diesel engine with a volume of 2.2 liters. and a power of 110 hp. has proven itself with positive side. The motor is generally reliable, and its main problem is the injection pump, which rarely lives up to 200 thousand km.

The DCi series was created in cooperation with Renault, after merging into one concern. Turbodiesel received an injection system common rail and turbocharger with variable geometry. It improved him performance indicators, however, significantly increased the cost possible repair. Among the shortcomings is the sensitivity to fuel quality. This directly affects the life of the injectors.

It was installed on the model and a 1.5-liter diesel engine developed by Renault. This engine is suitable for connoisseurs of economical movement. It features ultra-low fuel consumption. It is also very sensitive to the quality of the fuel consumed. Already by 100-150 thousand km, it is likely that the nozzles will need to be replaced. Repair or restoration by the manufacturer is not provided. The turbocharger runs on average up to 150-200 thousand km. Frequent cases of failure fuel pump, as well as turning the liners. With all this, the engine has earned a positive reputation: most owners are satisfied with it.

Nissan Almera Classic (2006-2012)

The model was offered with a single unit. It was a sixteen-valve four with a volume of 1.6 liters with a capacity of 107 hp. He did not cause serious problems to the owners of the Nissan Almera Classic. However, there were problems with it. Some of them resonate with weak points motors of past generations.

Problem areas

The timing chain drive is quite reliable. Basically, it takes care of 200, and in some cases 300 thousand km without problems. Only the stretching chain is annoying, due to which there may be failures after a sharp release of gas. The reason is the poor quality of workmanship. The only way out of this situation is a replacement.

With a run of 140-180 thousand km, the engine may stall after starting. This is a common sensor problem. camshaft. It happens that turning it clockwise eliminates the malfunction, but replacement may also be required.

With runs of 150-200 thousand km, the fuel pump may start to buzz. At the same time, the engine may be difficult to start, sometimes not the first time. Sometimes cleaning helps. fuel filter, but most often in such a situation, the fuel pump will need to be replaced.

Sometimes the cooling fans can spin constantly, regardless of the temperature of the coolant. This is a known issue with fan wiring. Most often, the cause is a broken wire due to poor-quality insulation.

Almera G15 (2012-2018)

Nissan Almera G15 was also equipped with only one power unit. They became the Renault engine with the K4M index. This engine was not a novelty, and since 1999 its various modifications have been encountered on the most different models concern. The new 16-valve cylinder head differs from the K7M progenitor. Its volume is 1.6 liters, and the power of the version installed on the Almera G15 is 102 hp.

The advantages of a motor with 16 valves include efficiency, lower vibration and noise levels. However, compared to the 8-valve engine, it is more complex and expensive to maintain. It is necessary to carefully monitor the condition of the timing belt and rollers, since in a more complex cylinder head, the consequences of a broken belt must be corrected with expensive repairs.

Typical malfunctions

The engine often troit. The problem may be in the ignition coil, and in the candles, and even in the injectors. To compile a complete picture, when such a problem appears, it will not be superfluous to measure compression.

There are frequent cases of floating revolutions and unstable work. common cause Such problems are a faulty crankshaft position sensor or ignition coil.

If the engine suddenly stalls, then the cause should be sought in the sensors or faulty spark plugs. Dirty throttle or air filter can also cause this problem. But sometimes it happens that the reason lies in the malfunction of the computer. When strong vibration, first of all, it is necessary to check the right engine mount. This is a characteristic disease of these motors.

In general, the engine is very common and studied. The resource laid down by the manufacturer is 400 thousand km. In practice, many of these motors go much more.

Nissan Almera engine volume of 1.6 liters. It's a petrol 16 valve motor with a cast-iron cylinder block and a timing belt. The power unit is put on Renault Logan, Lada Largus and assembled in Tolyatti, in the same place where Nissan Almera is made for the Russian car market. Renault motor K4M has a fairly large motor resource, but a broken timing belt leads to serious problems. Firstly, this bent valves and damage to valve seats and piston crowns. But more about everything later in our article.

Nissan Almera 1.6 engine device

The Nissan Almera motor is a 4-cylinder 16-valve unit with distributed fuel injection and a timing belt. Base cast iron block. The cylinders are bored directly into the block. The order of operation of the cylinders: 1-3-4-2, counting - from the flywheel. The cylinder head is made of aluminum alloy. The engine has hydraulic lifters, so it does not need manual adjustment. valve clearance.

Almera 1.6 camshafts are driven by a toothed belt from a pulley crankshaft. On the shaft next to the first (counting from the camshaft gear pulley) support neck, a thrust flange is made, which, during assembly, enters the grooves of the block head and cover, thereby preventing axial movement of the shaft. The camshaft pulley is not fixed on the shaft with a key or pin, but only due to the friction forces that occur on the end surfaces of the pulley and shaft when the pulley fastening nut is tightened.

With proper use nissan engine Almera can easily move 400,000 kilometers. On Almera, the engine can be combined with a 5-speed mechanical box, or with a 4-band automatic. Transmission used from the same Renault Logan.

Engine characteristics Nissan Almera 1.6

• Working volume - 1598 cm3
• Number of cylinders - 4
• Number of valves - 16
• Cylinder diameter - 79.5 mm
• Stroke - 80.5 mm
• Timing drive - belt
• HP power (kW) - 102 (75) at 5750 rpm in min.
• Torque - 145 Nm at 3750 rpm. in min.
• Maximum speed - 185 km / h
• Acceleration to the first hundred - 10.9 seconds
• Fuel type - gasoline AI-92
• Fuel consumption in the city - 9.5 liters
• Combined fuel consumption - 7.2 liters
• Fuel consumption on the highway - 5.8 liters

Timing drive engine Nissan Almera 16 valves

The main attention during the operation of this motor should be given to the timing drive. Belt replacement must be carried out strictly according to the manufacturer's instructions. That is, once every 60 thousand kilometers or after 4 years of operation, if the mileage is not reached. Breakage of the belt, jumping, shearing of the teeth leads to bending of the valves. And that's a pretty expensive fix. Since you have to sort out the cooking of the cylinder block.

Another feature of the Nissan Almera engine can be considered the absence installation marks on the camshaft pulleys. Moreover, they do not have any dowels and are not fixed in one position. When replacing the belt, it is necessary to fix the crankshaft and camshaft with special devices; without this, replacing the belt will be a very difficult task. To fix the crankshaft, you will have to release a special technological hole in the cylinder block and screw the retainer bolt there. To fix the camshafts, you will have to insert a special plate into the slots of the camshafts (on the reverse side, relative to the camshaft pulleys). In general, if you are not ready for this, it is better to change the timing belt in the service.

A detailed review of the Nissan Almera car, created specifically for Russians, shows some specifications, it is told about the engine, transmission, trim levels, the advantages and disadvantages of the car are considered.

We have already reviewed this vehicle here, but used to write this article personal experience the author, who worked for an authorized Nissan dealer, so we hope that the article will be useful.

So let's get started.

Start of production

Nissan Almera- a car B-class, its production was established in 1995 in Japan. But only the first generation of the N15 car was purely Japanese, and the car existed on the market for 5 years, was produced in sedan and hatchback bodies (in 3 and 5-door versions).

The second model Nissan Almera N16 appeared in 2000, new car acquired a more streamlined shape and slightly increased in size.

This version has already been assembled in several countries: in the UK, Latin America and South Africa.

In 2006, the N16 was replaced by one of the most popular at that time in Russia Almera models Classic B10, which was officially discontinued in 2013.

The new Nissan Almera in the G15 body has been produced in Russia since 2012, but this car with cars previous generations has nothing to do with the same name.

In this case, the Russian-assembled sedan became the "brainchild" of three concerns at once: Renault, Nissan and AvtoVAZ, and its "stuffing" contains more "Renov" components and parts than Japanese ones.

What is the Russian Nissan Almera

Outwardly, the Russian Almera is a Nissan Bluebird Silfi of the 2005-2012 model, but this car has a lot of “insides” from Renault Logan, and these are:

• engine;
• Transmission;
• salon;
• suspension.

The basis of the Russian-French-Japanese brand was the "Nissan" B0 platform, many French cars were built on it, such as Renault Sandero, Logan, Duster, Kaptur.

Also B0 is the basis VAZ models Lada X Ray and Largus, "Nissan" Tiida, Note, Wingroad, Cube.

The assembly of the Nissan Almera G15 is carried out at AvtoVAZ in the city of Tolyatti, already initially the creators set out to launch a series budget car with a brand name on the basis that the car will be willing to buy.

And the marketing move was made correctly: there were many hunters to purchase famous brand for little money, we should pay tribute to the fact that the build quality and components turned out to be at a quite decent level.

On the outer part of the Almera body there is a considerable amount of chrome elements, in particular, door handles, a radiator grille, side mirror linings, and lower door moldings are covered with chrome.

The car from afar can be recognized by the headlights of a very original shape and a relatively high front bumper.

power unit

Nissan Almera engine - gasoline 16-valve, four-cylinder, injection, with a displacement of 1598 cm3.

It is the only power unit installed on this car, and there are no other options here.

The 102-horsepower Renault K4M model is reliable and unpretentious; it has been produced since 1999 and is also installed on many Renault cars: Kangoo, Sandero, Logan, Scenic, Laguna, Fluence, Clio 2.

The real resource of the internal combustion engine is about 400 thousand km, in many ways this engine is similar to the 8-valve single-shaft K7M, only the engine is 102 hp. With. already equipped with 16-cl. Cylinder head with two camshafts.

The timing drive of the engine is belt driven, the belt life is approximately 60 thousand km. The K4M engine complies with Euro-4 standards, runs on gasoline fuel AI-92.

Transmission

There are two types of transmission installed on the sedan:

• 5-st. "Mechanics";
• 4-st. automatic transmission.

Almera automatic transmission is the same as on Renault Logan, complete with 16-cl. engine, but it is quite an old design, although simple and inexpensive.

In automatic transmission repair, it is simple and maintainable, but not very reliable: most of all, this unit is afraid of overheating.

Manual transmission is also not new model, this gearbox was installed on many Renault cars.

Unlike the "machine", it rarely breaks down, its resource is an average of 200,000 kilometers in mileage.

According to the technical specifications, the oil in the gearbox should not be changed during the entire life of the car, but in Russian conditions it is still recommended to replace it: for automatic transmission - after 60,000 km, for manual transmission - after 75,000 km.

Specifications

Almera G15 is presented in only one sedan body, and the dimensions of the car are rather big. With a wheelbase of 2700 mm, the length of the car is 4656, height - 1522 and width - 1695 mm.

The manufacturer took into account that the machine will be operated according to Russian roads, That's why ground clearance here is quite decent (160 mm).

In a configuration with a manual transmission-5, the car accelerates to 185 km / h, gaining a “hundred” in 10.9 seconds.

Consumption per hundred kilometers when driving on the highway is 5.8 liters, in the city, fuel consumption increases to 9.5 liters.

In the variant with automatic transmission the economic indicators of the car are somewhat worse, the gasoline consumption per 100 km of track here is:

• in the city - 11.9 liters;
• on the highway - 6.5 liters.

Even with the “automatic”, Nissan accelerates more slowly (in 12.7 s), and maximum speed is equal to 175 km/h.

The volume of the gasoline tank in all modifications is 50 liters, the curb weight is about 1178-1224 kg (depending on the configuration).

The front suspension of the sedan is MacPherson, on rear axle- beam. Wheel disks in all trim levels are installed with the 15th radius, the turning diameter is 11.4 m.

Ventilated brake discs are placed on the front axle, rear brakes drums here.

The ABS system is present in all trim levels, and an EBD brake distributor is also provided in all Almera variants.

Options Nissan Almera

Almera G15 for Russian market produced in five configurations:

• Wellcome;
• Comfort Plus;
• Comfort A/C;
• Comfort;
• Tecna.

Welcome performance is considered basic, and the set of options here is minimal. The basic version has:

• Airbag front passenger and driver;
• Immobilizer;
• Electric front windows.

The car is equipped with steel wheels, the steering column can only be adjusted in height. There is a full-size spare wheel in the trunk, the seat upholstery is fabric.

Of course, the car obviously doesn’t shine with the wealth of decoration, but it’s also very inexpensive, buy a Nissan Almera from official dealers in 2016 it is possible from 511 thousand rubles (under the recycling program).

Of all the modifications presented to the Russians, the most charged is nissan car Almera Tekna, fog headlights, heated mirrors and front seats, air conditioning, an audio system with MP3 and 4 speakers, a navigator, on-board computer, multimedia system.

The steering wheel rim is wrapped in leather, all power windows and side mirrors, painted in body color and equipped with an electric drive.

The seats are upholstered quality material, complete with cast wheel disks. Such a car costs from 727 thousand rubles, but under the recycling program, car dealerships offer it for 100 thousand rubles. cheaper.

Salon and trunk

The interior of the Nissan Almera is spacious, there is plenty of space in it, not only front, but also rear passengers are freely accommodated here.

The driver's seat is equipped with mechanical adjustments, the steering column is adjustable only for tilt.

The glove compartment under the dashboard is large and can hold a lot of useful things, but there is no armrest. It should be noted that the interior of the Almera G15 is in many ways reminiscent of the interior of the 1st generation Logan.
