Renault Megane 1 - compact family car, which entered the production line in series in 1996. The buyer had a choice of three versions: sedan, hatchback and station wagon. The engine range included several gasoline and diesel options, differing in dynamic and technical characteristics. Read about what Megan is like with a diesel engine and how carefree it is to own such a car.

Specifications

When Renault Megane of the first generation just started mass production, the car was positioned as compact and lightweight a car, which, with high efficiency, was capable of transporting a significant amount of luggage. That is why, in some places, the numbers are truly amazing.

The length of the five-seater four- or five-door Renault Megane with a diesel engine varies from 3931 to 4440 mm, the longest length went to the station wagon. Despite the fact that in the photo this car looks quite large, we can confidently say that Renault Megane can be classified as compact.

The width for all three versions, including hatchback and station wagon, is 1700mm. Such parameters created a certain popularity for this car, since with a wheelbase of 2580 mm, Renault Megane capable of negotiating fairly tight turns and maneuvering in really tight corners. The height varies from 1365 to 1420mm, which gives additional opportunity drive through low arches and park in a low garage.

The weight characteristics of the Renault Megane deserve a special mention. Despite the fact that even reviews talk about this car as a fairly spacious family vehicle, the weight of the car can amaze even an expert. According to the passport data, the curb weight of the Renault Megane varies, depending on the engine and body type, from 1010 to 1275 kg. Wherein maximum load The Renault Megane station wagon is capable of taking over. If you believe the reviews, the maximum total weight of passengers and luggage can reach almost 600 kg.

The suspension here is combined: the Renault Megane has a traditional MacPherson strut at the front, and a semi-independent mechanism at the rear. This allowed the station wagon to carry even more luggage. The brakes are disc at the front and drum at the rear.

It's time to move on to dynamic characteristics. Renault Megane with a diesel engine was produced in only three variations. Three engines with a volume of 1.5 liters and a power of 64, 95 or 100 Horse power available for Renault Megane sedan, station wagon and hatchback. All engines are in-line, with a cylinder head for 4 cylinders and a transverse arrangement in the engine compartment.

The lowest-power 1.5 diesel engine for Renault is capable of delivering up to 118 Newton-meters of torque at peak speeds. Wherein maximum speed, which Renault Megane is capable of developing, is only 160 kilometers per hour. Consumption is quite high for an engine of this configuration: 5.3 liters on the highway and as much as 8.6 in the city - almost a gasoline figure. Acceleration to 100 km/h occurs in only 16.5 seconds, and the power reserve, depending on the driving mode, will vary from 750 to 1100 km.

The “middle” from the line of 1.5-liter diesel engines has a power of 95 horsepower.

Structurally, the motor has one significant difference. There is an intercooler and turbocharging. This addition made it possible, with an equal volume, to significantly increase the power and torque of the Renault Megane.

For example, the maximum torque of this engine is achieved already at 4000 rpm and is 176 newton meters. Fuel consumption in the city reaches almost 8 liters per 100 kilometers, and on the highway this figure drops to 6. Acceleration to hundreds occurs in 12.3 seconds, and the maximum speed reaches 180 km/h.

The most powerful 1.5-liter engine in the line has a reinforced cylinder head and is capable of developing 100 horsepower. The torque here is truly amazing. It is equal to 200 newton meters. Acceleration to 100 kilometers per hour occurs in the same 12.3 seconds, but the maximum speed here reaches 183 kilometers per hour. Diesel consumption is good. If on the highway the car’s appetite is limited to only 4.4 liters, then in the city a 1.5-liter unit will not consume more than 6.8.

Drivers' impressions

Reviews speak volumes. In the case of Renault Megane with a diesel engine installed, reviews revealed everything possible problems and the disadvantages of such engines, including an unreliable cylinder head and oil leaks, find the most optimal way to solve them.

The largest number of complaints are received specifically regarding the operation of the cylinder head of the 1.5 engine, which, with significant mileage, either cracks or requires replacement of the gasket.

Eugene. Ownership experience 4 years.

I have become the third owner of a station wagon with a 1.5-liter diesel engine. The mileage is, of course, solid, so it would be surprising not to encounter cylinder head repairs. For such an operation, the service center quoted me a considerable amount, so I mustered my will and repaired the cylinder head myself.

Judging by the reviews, no fewer problems are caused by the Renault Megane cylinder head gasket, which, if the regulations are not followed, quickly makes itself felt.

Vladimir. Ownership experience - 2 years.

I have a station wagon with a 1.5-liter engine. The cylinder head gasket made itself felt almost immediately: I went and changed it. Otherwise, apart from a slight oil burn, I did not find any problems.

Another nuance of the Renault Megane is the difficulty of starting the engine in winter, which is typical for engines of a similar configuration.

Irina. Ownership experience - 3 years.

My station wagon with a 1.5 liter MT engine never let me down until the frost hit. Starting up became very difficult: I had to constantly use additives. Bought new battery- it helped, but the problem did not completely disappear.

Summary

Renault Megane with turbocharged or naturally aspirated diesel engine - reliable and economical car. Knowing certain nuances of this engine, you can avoid most problems when owning it and provide yourself with a trouble-free and durable car that will last for many years.

The 1.5 dci is a four-cylinder diesel engine with a turbocharger. The engine capacity is 1.5 liters, and power, depending on the modification, can vary from 64 to 110 horsepower. Engine index - K9K. It has been produced since 2001 and has undergone some changes during this time.

It is worth noting that this is one of the most popular turbodiesels created by the Renault-Nissan alliance. This internal combustion engine is most popular in Europe, so secondary market We can often see used Renaults and Nissans with this engine. By the way, this unit is installed on several more Mercedes.

From obvious advantages engine - good low-end traction, relative fuel efficiency. The disadvantages are poor sensitivity to the quality of diesel fuel, especially Russian, and maintenance requirements.

Indeed, in order for this internal combustion engine to serve for a long time and be properly maintained. And this is to change engine oil every 10,000 km or even earlier, while changing the timing belt - every 60,000 km and, of course, do not overheat.

The following problems can often be found in reviews:

1) Failure of the injection pump. Therefore, it is not recommended to purchase a version with a dephi fuel system, which is very demanding on the quality of fuel, and if it is filled in poorly, it will quickly die. It is recommended to take it with the Siemens (Continental) system. Delphi come on versions with a small amount of horsepower. Please check this point before purchasing.

Also with the Siemens system, models with a 6-speed transmission usually come manual transmission transmission Engines with 5 speeds are usually Delphi.

2) turbine failure. This happens most often due to improper use. As we know, a turbodiesel cannot be turned off immediately after stopping, and you need to let it run for a while; for this there is a customized auto-start system in the alarms.

4) Turn connecting rod bearings. This happens if you do not change the oil on time and extend the change intervals. Change it every 10,000 km and this problem should not arise.

In conclusion, I will say that before buying a car with a 1.5 DCI engine, you should carefully check not only the body, suspension, legal purity, but also the engine itself, how it works, scan its errors, find out how often the oil has been changed, whether there have been problems, and so on . Often there are 5-7 year old Megans with a mileage of 60-80 thousand, this, unfortunately, is not always true, the mileage could be changed. You can check it at the dealer, unless of course the mileage has been removed from the car's ECU.

When purchasing a car with DCI, you should regularly change the oil, filters, attachments- in general, everything you need, and choose a gas station that fills in really high-quality diesel fuel.

And it’s definitely not worth saying that this internal combustion engine is good or bad, since each copy has its own history and care, if we talk specifically about used options.

For reference: installed on Renault Megane, Clio, Scenic, Dasia, Duster, Nissan Qashqai, Tiida and other models.

Japanese manufacturers have reliable diesel engines. And which one is the most reliable? diesel engine of all the reliable ones in Japan?

Let's look at the most common modern diesel engines in the Japanese automobile industry.

What are these diesel engines, what are the strengths and weaknesses of Japanese diesel engines. They now dominate mainly in Europe, but they have begun to appear quite often in Russia.

But, unfortunately, they also have problems when their mileage exceeds one hundred thousand kilometers, and even for some up to one hundred thousand.

Delivery precautions diesel engines from Japan is due to their capricious attitude towards fuel. Their fuel system quite weak to the use of our diesel fuel.

Another problem is the availability of spare parts. There are practically no non-original spare parts from reliable manufacturers. Chinese ones appear, but their quality leaves much to be desired and does not at all correspond to Japanese quality.

Hence their very high price, much higher than for German spare parts. There are many factories in Europe that produce spare parts of decent quality and at prices significantly lower than the original ones.

The most reliable diesel engine from Japan

So what is the most reliable diesel engine from Japan? Let's rank the TOP 5 best diesel engines.

5th place

In fifth place you can safely put the 2.0 liter Subaru engine. Four-cylinder, turbocharged, opposed, 16-valve. Intake system Common Rail.

It must be said that this is the only boxer diesel engine in the world.

Boxer engine, this is when mutual pairs of pistons operate in a horizontal plane. This arrangement does not require careful balancing of the crankshafts.

Weak sides This engine, it is a dual-mass flywheel, it failed even before five thousand kilometers. Cracking crankshaft, until 2009, crankshafts and shaft supports were destroyed.

This engine is very interesting in its design, with good characteristics, but the lack of spare parts for such engines negates its advantages. Therefore, we give it the fifth place of honor in the Japanese range of diesel engines.

4th place

In fourth place we will place the Mazda 2.0 MZR-CD engine. This diesel engine began to be produced in 2002 and installed on Mazda car 6, Mazda 6, MPV. This was the first Mazda engine with a common rail system.

Four cylinders, 16 valves. Two versions - 121 hp. and 136 hp, both developing a torque of 310 Nm at 2000 rpm.

In 2005, it underwent modernization, with an improved injection system and a new injection pump. The compression ratio and adaptation of the engine with a catalyst for the emission of harmful gases have been reduced. Power became 143 hp.

Two years later, a version with a 140 hp engine was released; in 2011, this engine disappeared from the line of installed engines for unknown reasons.

This engine calmly nursed for 200,000 kilometers, after which it was necessary to change the turbine and dual-mass flywheel.

When purchasing, you should carefully study its history, or better yet, remove the pan and look at the oil sump.

3rd place

Also a Mazda engine, Mazda 2.2 MZF-CD. The same engine, but with a larger volume. The engineers tried to eliminate all the shortcomings of the old two-liter engine.

In addition to the increased volume, the injection system was modernized and another turbine was installed. They installed piezo injectors on this engine, changed the compression ratio and radically changed particulate filter which was the reason for all the problems of the previous two-liter engine model.

But the global struggle for the environment, both in Europe and Japan, adds trouble to all engines, and this is where a system is installed, with the addition of urea to the diesel fuel mixture.

All this reduces emissions to Euro5, but as always, in Russia this adds problems to all modern diesel engines without exception. This is simply solved here: the particulate filter is thrown out and the valve for afterburning the unburned exhaust is turned off.

Otherwise the engine is reliable and unpretentious

2nd place

Engine Toyota 2.0/2.2 D-4D.

The first two-liter Toyota 2.0 D-4D CD appeared in 2006. Four-cylinder, eight-valve, cast-iron block, timing belt drive, 116 hp. The engines came with the index “CD”.

Complaints about this engine were very rare, they all boiled down only to the injectors and the recirculation system exhaust gases. In 2008, it was discontinued and replaced by a new one with a volume of 2.2 liters.

Toyota 2.0/2.2 D-4D AD

They have already begun to make it a chain one, there are already 16 valves for four cylinders. The block began to be made of aluminum with cast iron sleeves. The index of this engine became "AD".

The engines are available in both 2.0 liters and 2.2.

The most good feedback about such an engine, both good performance and low fuel consumption. But there were also complaints, the main one being the oxidation of the aluminum head at the point of contact with the cylinder head gasket, approximately in the period of 150-200 thousand km. mileage

Replacing the head gasket does not help, only grinding the cylinder head and block, and this procedure is only possible with engine removal. And such a repair is only possible once; the engine will not withstand the second grinding of the head and block, the depth will be critical with the possibility of the valves meeting the head. Therefore, if the engine has traveled 300-400 thousand kilometers, with one grinding, it should only be replaced. Although this is a very decent resource.

Toyota solved this problem in 2009; with such malfunctions, they even replaced the engines with new ones under warranty at their own expense. But the problem, very rarely, does occur. Mainly for those who are not weak in igniting the most powerful version of this 2.2-liter engine model.

Such engines are still produced and installed on various models cars: Raf4, Avensis, Corolla, Lexus IS and others.

1 place

Honda 2.2 CDTi diesel engine. The most reliable small-displacement diesel engine. Very productive and very economical diesel engine.

Four-cylinder, 16-valve, variable displacement turbocharged, common rail injection system, lined aluminum block.

The injectors are used by Bosch, and not the capricious and expensive Japanese Denso ones.

The predecessor to this engine was built back in 2003, badged 2.2 i-CTDi. It turned out to be very successful. Hassle-free, dynamic and economical in fuel consumption.

Modern under consideration Honda engine The 2.2 CDTi appeared in 2008.

Of course, there were no typical malfunctions, but they were all extremely rare. Cracks in the exhaust manifold, but they appeared in the first editions, the Japanese reacted and this did not occur in subsequent editions.

Sometimes there were malfunctions of the timing chain tensioner. Also, sometimes the turbine shaft play appeared prematurely.

All these malfunctions arose from excessive constant loads and poor maintenance.

Honda installed this engine on Honda Civic, Accord, CR-V and others.

Of course, this engine has the lowest number of failures and breakdowns compared to all other engines from Japanese automakers.

We give it five points out of five, assign it the first place of honor and wish you to have a similar one in your car.

Small turbodiesels have already managed to win the hearts of millions of car enthusiasts. Their main advantages are affordable price and high efficiency, comparable to larger brothers. One of the first automakers to start producing small diesel engines was Renault, which developed the very popular 1.5 dCi in collaboration with Nissan. Today, many cars are equipped with this engine.

The smallest of Renault's line of diesel engines is power unit with the designation K9K debuted on the market in 2001. The eight-valve four-cylinder turbocharged engine with a Common Rail fuel supply system was offered in several versions - with power ranging from 64 to 110 hp. The main differences between the modifications are the equipment with injectors, turbocharger, flywheel, etc. The advantages of the unit include: relatively high power and low fuel consumption - on average about 6 liters per 100 km. The 1.5 dCi engine is widely used in Renault cars, Dacia and Nissan. Between 2003 and 2010, a turbodiesel was installed on a small SUV Suzuki Jimny, and after the start of Renault’s collaboration with Mercedes - both in the new A-Class models and in the Citan van (the same Renault Kangoo only with a characteristic star on the radiator grille).

Typical problems and malfunctions

The list of problems plaguing the 1.5 dCi is quite long. One of the most serious and most common is a malfunction of the power system. As a rule, this is due to the use of low quality fuel, which French diesel does not accept. This is especially true for engines with Delphi injectors, which may not withstand 10,000 km on poor diesel fuel. The cost of one nozzle is about 8-12 thousand rubles. In modifications with a simple system and “normal” nozzles, you can save a lot by trying to restore their functionality. In the case of piezoelectric injectors, the only solution is replacement.

The turbocharger on some copies can cause trouble after 60 thousand km. Turbochargers were used in two types - fixed or variable geometry.

Sometimes there are cases of cranking of liners and burnout of pistons - due to poorly functioning injectors. In addition, you have to deal with malfunctions of the EGR exhaust gas recirculation valve, which are common for diesel engines. On more powerful versions, problems occur with the dual-mass flywheel.

Other typical problem for a modern diesel engine - a particulate filter, which can be expensive. It’s better not to ask about the cost of a new one, but pray that the troubles associated with it will bypass you. Sometimes trouble comes from the engine control electronics: the boost pressure and shaft position sensors are especially vulnerable.

As you can see from the review, there are a lot of potential problems with the 1.5 dCi engine. However, the vast majority of them are due to improper operation. To avoid unnecessary and high costs in the future, owners diesel cars It is worth compensating for gaps in your knowledge due to the operation of only naturally aspirated gasoline engines.

Conclusion

Still, some consider the 1.5 dCi a rather risky choice. At the same time, most owners of cars with this turbodiesel are very satisfied with their purchase and want to see 1.5 dCi under the hood in the future. Before buying such a car, it’s still worth calculating how many kilometers you have to drive per year. If the mileage is short, then a car with a gasoline engine will be more profitable. Despite some flaws, the reliability of the 1.5 dCi is not inferior to most well-known diesel engines from more famous manufacturers.

With a 1.5 liter diesel engine remains the most popular and affordable among crossovers on domestic market. Technical characteristics such as high torque of up to 240 Nm (which gives powerful traction already at 1750 rpm), efficiency, smooth running and reliability make the engine ideal for use in any conditions, be it city or off-road. After the update and restyling, the diesel performance became even more deserved.

Technical specifications diesel 1.5 Renault Duster

The French automaker Renault installs the diesel model K9K 1.5 dCi on almost 12 of its Renault models. This diesel unit proved to be reliable, durable, economical, for which it earned universal popularity.

Instead of a chain, the Duster diesel engine uses a timing belt. Its durability is about 60 thousand km; it is after this figure that the manufacturer recommends changing the belt. The K9K 1.5 dCi diesel has 4 cylinders, each equipped with only 2 valves, resulting in a total of 8 valves for the entire engine.

Diesel for Dustera is equipped with the latest system Common Rail, which reduces fuel consumption, diesel fuel consumption is only 5 liters on the highway and 5.9-6 liters in the urban cycle. Naturally, such an engine becomes demanding on fuel quality. With such advantages, the diesel engine of an SUV is inferior to gasoline versions in terms of dynamic characteristics. When buying a diesel Renault Duster, you must remember that you only need to refuel with high-quality diesel fuel, otherwise clogging of the injectors and problems with repairs will inevitably occur. That is why many, fearing such problems, choose models with gasoline engines, despite their gluttony.
