Before starting a story about this bus, it should be noted that the NefAZ-5299 is not one car, but several modifications based on the model for urban, intercity and suburban passenger transportation. The car is often used on regular passenger routes.

History of creation

It's completely domestic project, which was put into assembly and production only in 2000. NefAZ-5299 is one of the most popular passenger buses, which are used as public transport in many cities.

Now more than 1,000 units of these models are assembled at the Neftekamsk Automobile Plant every year. This technique successfully used by fleets across the country.

Technical data

Acquaintance with technical part bus NefAZ-5299 will help to appreciate all the advantages of this model. KamAZ trucks were used as the base platform. These are reliable loading platforms that will help the bus easily overcome a variety of obstacles on the way, they have been tested by time and a lot of tests of varying degrees of complexity. Each detail in the undercarriage of these machines has a huge resource and high strength reserves, which in the best way affects the durability and operation of the machine.

All equipment designed for control and monitoring, as much as possible meets the requirements of international standards for such equipment. This series of buses has a high safety record. There are devices and systems of both passive and active safety.

Power part

The NefAZ-5299 bus can be equipped with several types of engines, depending on the modification. So, the KamAZ-820.61-260 engine produces a maximum power of 260 Horse power at 2200 rpm. Its maximum torque is 931 Nm. Engine - eight-cylinder, V-shaped. The working volume is 11.76 liters. The power unit designed and built specifically for liquefied gas. The motor is equipped with a turbocharger and an inercooler. There is an electromagnetic dispenser, and the injection is distributed. The engine fully complies with Euro-4 standards. Paired with this power unit is a four-speed automatic transmission.

NefAZ-5299 is also equipped with Cummins 6ISBe270B diesel power units. The power of this engine is 270 hp. with. at speed crankshaft 2500 rpm The torque that the motor produces is 970 Nm. The unit has six cylinders with an in-line arrangement. Volume - 6.7 liters. The engine is also equipped with a turbine and an inercooler. Like the previous one, this motor fully complies with Euro-4 standards. Consumption diesel fuel on "Cummins" - 24 liters per 100 km. The fuel tank has a volume of 250 liters.

Modifications

Model 5299-10 is a standard bus with a high floor. This is one of the very first buses that were produced at the factory. I must say that at the very beginning of production, the developers did not have a clear design.

It was borrowed from the Belarusian MAZ-104. The remaining models, which were produced later, already had original design, developed by the specialists of the plant.

Modification 5299-11 is base model intended for suburban transportation. There are two doors for passengers. The number of seats has been increased to 45. The total number of passengers is 77 people. The cabin is equipped with tourist seats, which are great for long trips.

The audio system is organized in such a way that passengers can enjoy music and it does not distract drivers in any way.

Model 5299-30 is a semi-low floor bus. Its capabilities, unlike the base model, are somewhat increased. The salon accommodates up to 115 people. The designers of the bus did not forget about the disabled. There are special places for them. There is a ramp in the central door allowing wheelchair access. In the middle of the cabin, you can install a wheelchair and securely fasten it with special belts.

About repair and maintenance

Maintenance and repair of NefAZ-5299 is not difficult. The machine was developed on the basis of components and mechanisms of KamAZ trucks. The mechanics have vast experience in repairing trucks and will be able to handle this bus without difficulty. Spare parts (NefAZ-5299) are maximally unified with parts and assemblies of KamAZ trucks, so you can easily find anything you want, and even something that is rare. Any spare units and parts can be purchased from official dealers. As for the durability of the bus, good driving, as well as timely maintenance these machines are able to serve for several years before the very first repairs.

Model prices

For new NefAZ-5299 buses, the price is from 5 million rubles. There are also many offers for secondary market- used copies will cost much less. But it must be taken into account that such machines require certain costs for restoration and bringing them back to normal.

The NefAZ 5299 bus was put into mass production in 2000. It is one of the most common types of special equipment used as municipal transport. Neftekamsky car factory produces about 1000 copies of these buses annually. They go to bus fleets all over the country.

Technical characteristics of the city bus NefAZ 5299

Familiarization with technical specifications NefAZ 5299 allows you to evaluate the advantages of buses of this series. The basis for the production of buses was the chassis of serial KamAZ trucks. Truck platforms, proven by time and numerous tests, allow buses to easily overcome any obstacles on the road. All elements of the chassis have a high margin of safety and show themselves well in operation. Control and management equipment comply with all international standards for buses of this class. The level of active and passive safety is also at a high level.
