System Description
This system integrates the engine's ignition control, gas control, and generator speed regulation control, replacing conventional universal ignition systems and electronic speed regulation systems. It enables more precise control over ignition energy, ignition timing, and fuel supply, resulting in smoother and more reliable engine operation. Meanwhile, it achieves significant improvements in fuel consumption and emissions. This system is applicable to various fuels, including pipeline natural gas, biogas, CNG, LNG, and LPG.
System Advantages
1. Gas engines integrated with this system maintain power and torque levels exceeding those of the original diesel engines.
2. The system adopts controls such as BOSCH sensors and IMPCO proportional mixers, ensuring consistently stable intake pressure for enhanced operational stability and safety.
3. Featuring integrated control of engine gas supply and ignition, the generator set delivers superior overall performance with low operating costs.
4. Superior starting performance, stable operation, low noise, and minimal vibration.
5. High cost-effectiveness: spare parts are reasonably priced and easy to maintain.

The 500kW Weichai gas generator set is classified as non-continuous operation power generation equipment. If operated continuously for more than 12 hours, its output power will decrease to approximately 90% of the rated power. Natural gas generator sets offer moderate power output. However, owing to their compact size, flexibility, and easy operation and maintenance, they are widely applied across sectors including mining, railways, field construction sites, road maintenance, as well as factories, enterprises, and hospitals, serving as backup or temporary power supplies.
