Before starting a story about this bus, it should be noted that NefAZ-5299 is not one car, but several modifications based on a model for urban, intercity and suburban passenger transportation. The car is often used on regular passenger routes.
History of creation
This is a completely domestic project, which was launched 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 at Neftekamsk car factory more than 1000 units of these models are assembled every year. This technique is successfully used by car fleets throughout the country.
Technical details
Acquaintance with technical part the NefAZ-5299 bus will help to evaluate all the advantages of this model. As base platform used KamAZ trucks. 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 difficulty. Each part in the chassis of these machines has a huge resource and high safety margins, which is reflected in the best way on the durability and operation of the machine.
All equipment designed for control and monitoring meets the requirements of international standards for such equipment as much as possible. This bus series has a high safety record. There are devices and systems of both passive and active safety.
Power section
The NefAZ-5299 bus can be equipped with several types of motors, 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. The engine is an eight-cylinder, V-shaped. The working volume is 11.76 liters. The power unit designed and built specifically for the supply of 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. A four-speed automatic transmission works in tandem with this power unit.
NefAZ-5299 is also equipped with Cummins 6ISBe270B diesel power units. The power of this engine is 270 hp. with. at rotational speed crankshaft 2500 rpm The torque produced by the motor is 970 Nm.
