Product advantages

Power performance

Coefficient of torque reserve > 30 %, high output torque at low speed.

The engine is specially developed according to the operating conditions of construction machinery, and its power performance is equivalent to that of diesel engine.

Economy

The electronically controlled single point injection system guarantees precise control and low fuel consumption.

The four-valve structure and the high-efficiency turbocharger guarantee high intake efficiency and full combustion.

Reliability

The latest OH6 fuel system is used, which ensures high reliability.

The ignition coil is integrated with the spark plug, such that the high voltage line is omitted, and the reduction of conductivity of the high voltage line on rainy days can be avoided accordingly.

Knock monitoring is provided, such that faults such as piston burnout caused by fuel can be avoided.

Comfort

Mild combustion ensures low engine vibration and low noise.

Its structure is identical with that of diesel engine, as well as the advanced technologies adopted on them.

Adaptability

The connection method of gas engine to the vehicle is identical with that of diesel engine, and the parts are highly universal.

The electronic control unit is arranged on the engine, facilitating the layout of wire harnesses.
