Compressed Natural Gas Engine

Advantages of Natural Gas Engine:
Advantages of Natural Gas Engine: Asdopting the electronic control multi-point injection and theoretic air and fuel ratio combustion strategy, the power performance and acceleration performance of NG engine are much higher than that of single-point injection and lean burn engine.
The main maintenance parts, such as oil filter, air filter, pressure reducing valve and ignition coil, are all mounted in the right side, while the inlet and outlet in the left side (facing the fan), which brings the convenience to the maintenance.
The adoption of the world advanced multi-point electronic fuel injection system not only brings the lower gas consumption and better economy, but also the higher emission standard.
The key parts, such as pressure reducing valve, ECU, and ignition coil, are all purchased from the world-famous brand.
