October 31, 2023. Three new gas-engine vehicles are presented by KAMAZ at the St. Petersburg International Gas Forum 2023, which has opened today in the Northern Capital of Russia.
In particular, the company has for the first time presented to the general public the mobile instrumentation workshop 62501 based on the KAMAZ-6250 gas-powered crew-change bus. The vehicle was developed specifically for the oil and gas industry. The new model is designed mainly for maintenance and repair of instrumentation at facilities remote from stationary repair shops. Passenger capacity is three passengers plus a driver.
The vehicle is equipped with a gas inline six-cylinder engine with a capacity of 279 horsepower (Euro 5), a six-speed automatic transmission. Smooth ride is ensured by a front suspension with long leaf springs, hydraulic telescopic shock absorbers and a stabilizer bar. The rear suspension is pneumatic, with four pneumatic elements. The body has a load-bearing frame (welded from steel pipes) and an external decoration made of composites. The total weight of the vehicle is 16 tonnes, the length is 9,660 mm, the height is 3,780 mm, the width is 2,550 mm.
The second exhibit of KAMAZ is a low-floor gas-engine commuter bus NEFAZ-5222. This is an effective solution for transportation of personnel. The new product is equipped with a six-speed automatic transmission with a built-in retarder which reduces brake lining wear. The energy-efficient, powerful enough gas engine (290 hp) complies with the Euro 5 environmental standard and runs on methane gas fuel.
At its stand, KAMAZ PTC is demonstrating a new in-line six-cylinder engine with forced ignition, running on natural gas. The engine with a power of 460 horsepower and a torque of 2000 Nm complies with the Euro 5 environmental class, and is also unified in all main components and assemblies with the KAMAZ R6 910 diesel engine, which has already proven itself in operation. These gas engines will be installed on long-haul tractors of the KAMAZ K5 generation. The engine has high consumer properties. By the way, the service life of the R6 gas engine is 1,000,000 km, and in terms of fuel efficiency and service intervals, it is not inferior to the best world analogues.
