Introduction to Yuchai Power Generation Gas Engine

Dec. 12, 2018

As an independent manufacturer in China, Yuchai's engine is widely used in trucks, passenger cars, construction machinery, agricultural equipment, ships and power generation, special vehicles, light vehicles and other fields.


In this article, we mainly talk about Yuchai power generation gas engine features and its main technical parameters.


Yuchai Power Generation Land Gas Engine


Yuchai Gas Engine Technical Features:

1. Adopt clean fuel, energy saving and environmental protection.

2. Based on the professional development of Yuchai mature batch production platform, the design of special gas engine cylinder head, piston ring group, camshaft, intake and exhaust system and other key development, the reliability of the whole machine is high.

3. Adopt advanced mature gas control system to achieve lean combustion, high thermal efficiency, low gas consumption rate, low discharge temperature, high reliability and stable control.

4. Soft combustion, ultra-low noise, low vibration and good comfort.

5. Parts and diesel engine models have a high general rate, wide service network, mature parts market and convenient maintenance.
