Homogeneous Compression Ignition Method for Natural Gas Generator Sets

Traditional gasoline engines have low thermal efficiency, while traditional diesel engines struggle to solve the problems of soot and NOx emissions. Natural gas generator engines adopt the Homogeneous Charge Compression Ignition (HCCI) combustion mode. High - octane fuel is injected into the intake port to form a homogeneous mixture, and high - cetane fuel is directly injected into the cylinder to initiate ignition, potentially achieving efficient and clean combustion.

Before the ignition of the mixture in a natural gas generator set, a low - concentration homogeneous mixture is formed in the combustion chamber. When the in - cylinder temperature is compressed above the auto - ignition temperature of natural gas, the homogeneous mixture starts to ignite, thus completing the homogeneous charge compression ignition combustion. The natural gas engine with homogeneous charge compression ignition combines the operating characteristics of both spark - ignition and compression - ignition combustion modes in its operation. The mixture is formed by pre - mixing, and combustion is achieved through compression ignition. Dingbo Power, a generator manufacturer, controls the load by means of quality adjustment and removes the throttle valve. Research results show that the homogeneous charge compression ignition combustion mode is suitable for a variety of fuels, including gasoline, diesel, and natural gas. As a gaseous fuel, natural gas can more easily form a homogeneous mixture compared to liquid fuels such as gasoline and diesel. Coupled with its high octane number and excellent anti - knock performance, natural gas generator engines can use a relatively high compression ratio, making it easier to achieve the compression - ignition combustion mode.

The homogeneous charge ignition combustion mode uses both high - octane fuel (such as gasoline) and high - cetane fuel (such as diesel). The high - octane fuel is injected into the intake port to form a homogeneous mixture during the intake and compression processes, and the high - cetane fuel is directly injected into the cylinder to initiate ignition. This combustion mode can achieve a thermal efficiency close to that of diesel engines while reducing engine emissions. The homogeneous charge ignition combustion mode has always been a hot topic in research.
