4.6L Powerpack for Natural Gas and Biogas Engine
Descriptions
1. High power density
2. The base engine is developed based on MAN series, and
specifically improved for gas fuel, made which reliable and durable
3. Modular design and aluminum castings are used, so the engine has
light weight and low failure rate
4. Integrated cylinder head structure, four valves, overhead
camshaft design with compact structure
5. Advanced electronic control fuel system of continuous flow,super
durable design, especially resistant on dry and dirty gas
6. Self adaptive and self-learning abilities on gas composition
7. Closed-loop control on fuel
8. Electronic speed governing
9. Support CAN J1939 communication
10. SAE flywheel housing and flywheel
11. Using theoretical air-fuel ratio scheme, high exhaust
temperature,whcih can be used for GHP application.
