To meet global environmental issue, so-called green house effect, lack of petroleum energy and rapid up and down change of energy cost, the expectation for gas engine has been expanding since about 20 years. There are several types of gas fuel such as natural gas, liquid petroleum gas, sewage gas, coal bed gas, coal mine gas and synthesis gas. The synthesis gas origin comes from waste materials, for example wood, plant, and town waste goods, using heat synthesis process. This is a sort of biomass fuel gas. The composition of synthesis gas is unstable, and a calorific value is easily changeable. Which derive unstable combustion and deteriorate energy efficient utilization. The improvements of performance gas engine, BMEP and the power generation efficiency, in recent years are remarkable, which were based on the advanced combustion method. The lean burn has an effect on low NO_x emission and increasing BMEP. Pre-combustion method has an effect on increasing thermal efficiency and BMEP. Another important point is ignition energy, especially unstable synthesis gas will use as the fuel of engine. Under these technical issues, the suitable combustion ignition method and technical points are described in here.
