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 *2V
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) ****2meters buses, coaches
(2) Various special vehicles and trucks
