Features
With four-valve structure, centrally and vertically arranged fuel injector and new fuel mixing technology, this engine delivers high air intake efficiency, uniform atomization and good load transient response. Its working efficiency is improved by 12%.
The maximum torque is over l000N.m, and the torque reserve is as high as 36%, which is 20% higher than similar products.
The power and economy are both considered under common working conditions, and the minimum fuel consumption is 195g/kW.h.
A 180 BAR high combustion pressure design makes its environmental adaptability 7% higher than the similar products. Without auxiliary air intake heating device, the cold starting temperature is -15℃.
Frame type high strength alloy engine body, one-piece cylinder head and rear gear chamber result in small volume, light weight, high reliability and a noise of 3dB (A) lower than similar products.
By reference to SPS manufacturing standard of German Volkswagen, the average overhaul period is over 15000h, which is 50% longer than similar products.
