Main Features of Natural Gas Diesel Engine:
1. High precision air fuel ratio closed-loop control.
2. Adopt water cooling supercharger and electronic control exhaust release valve to increase reaction speed
3. Adopt superior ignition system, each cylinder ignites independently to make full use of ignition energy and increase combustion efficiency. The system can ignite steadily with battery voltage from 8V to 32V
4. Idle speed adjustment and overspeed protection function: Electronic air throttle enables engine to have functions of over-speed protection and idle speed adjustment. It can meet the requirements of buses.
5. Adopt under-pressure combustion and optimum ignition angle control in advance.
6. It has fault diagnosis function. Trouble lamp (MIL) can remind driver timely
