Domgfeng Cummins Z14 engine with low fuel consumption and national VI emission standards decreases self-weight by 250kg and consumes 2-3% less fuel due to upgrade in high-pressure ratio, low friction and efficient supercharger.
Low friction power cylinder and efficient supercharging system and other five measures decrease about 5% fuel consumption.
Maximum power of 520Ps and torque of 2500N·m can be reached in 900rpm.
Dongfeng Cummins Z14 engine largely decreases noise by 5-6% through low idle adjustment, gear and piston accuracy optimization.
After high temperature, high altitude, high humidity and mountain and cold areas experiments, B10 life span increased to 1.6m kilometers.
