August 26, 2021, Xiangyang, China, Dongfeng Tianlong KX 600hp vehicle is equipped with Dongfeng Cummins Z14 600hp engine; Tianjin KR6.8m van is equipped with Dongfeng Cummins B6.2 six cylinders engine. Here are some advantages of the two engines:

1.Dongfeng Cummins Z14 engine with national VI emission standards

Dongfeng Cummins Z14 engine reaches national VI B emission standards with maximum power of 600hp and peak torque of 2750N.m.

Low friction power cylinder, efficient supercharging system and other designs decrease fuel consumption by about 5%; the optimized and light-weight designs decrease self-weight by 250kg.

B10 engine life increased to 1.6 million kilometers and experienced high temperature, high altitude, high humidity, mountains and cold areas adapt experiment and 6 million kilometers road tests.

2. Dongfeng Cummins B6.2 engine with national VI emission standards

Maximum power of 191kw and maximum torque increased to 1020N.m;

Optimized cooling system prolonged component life span; unique supercharger and turbine expansion pressure integrated design increases trapping efficiency and torque by 3-4%, and thus power and fuel economy were improved largely; besides, the vehicle only weighs 510kg.
