Natural Gas Engine (CNG Engine)

L-series Diesel Engine (Aowei): CA6SL1 Natural Gas Engine (CNG Engine)
Main Features of Natural Gas Engine:
1. ECU collects various real time parameters of the engine to control jet volume of natural gas and supercharging pressure accurately and to perform closed-loop control of air fuel ratio by oxygen sensor.
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
7. Multiple engine protection functions can guarantee safe and reliable running of the engine
Application of Natural Gas Engine (CNG Engine):
(1) 10-12meters buses, coaches
(2) Various special vehicles and trucks
