4.2L Powerpack for Natural Gas and Biogas Engine
Descriptions
1. The engine is developed based on consultation from German
company FEV
2. The base engine is featured with integrated crankshaft, which is
made of alloy cast iron, make the engine
smaller, weight reduced and reliable
3.With Yuchai exclusive piston ring sealing technology, the
lubricating oil consumption is 20% lower than that
of other domestic products of the same power level
4. Specific improvements on gas fuel, making the engine
reliable,durable and cost-effective
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.
