中文摘要	With rapid increase of worldwide internal combustion engine retain quantity and excess exploitation of petroleum resources that triggers more intense discrepancy between demand and supply of fuel, need for developing fuel replacement energy sources is urgent.. China enjoys abundant resources of combustible gas. Combustible gas, as substitute fuel for internal combustion engine, is a desirable energy source. The development of gas internal combustion engine can not only take full advantage of current energy resources to relieve the pressure of petroleum shortage, but also is capable of supplying electricity to the areas which face a circumstance of electricity deficiency, exerting its strength in the field of distributed energy generation. This paper mainly discuss the status today and the future development trend of gas internal combustion engine, the technical problems and advantages of internal combustion engine development。The influence of biomass gas from gasification to the internal combustion engine is deeply analyzed from the aspect of the components of gas from gasification, the combustion characteristic, the heat value, and the impurity. Given the phenomenon of valve spring fracture frequently of the 8300 gas internal combustion engine in the practical application carefully research of valve train reveals that acceleration change sharply is the main reason. A new cam is designed to overcome the defects of old cam and also to satisfy the request of internal combustion engine fueled with gas from gasification. Guangzhou Institute of Energy Conversion, Chinese Academy of Sciences, with the "national high-tech development plans" ('863 'Plan) support, launched a 5 MW biomass gasification-steam integrated generation combined cycle demonstration project. Experiments were carried out to analyse the aspects of the combustible gas consume rate, exhaust temperature, peak eruption temperature and the emission characteristic smoke, NOx, CO, HC. The experiment suggests that the bad performance of economic and power characteristics is the result of the lower heat value and the excessive components for hindering combustion. the proper air fuel ratio，and enhancement of gas flow in cylinders, and catalyzing are effective ways to lower the gas emissions of internal combustion engine fueled with biomass gas from gasification. Simulation of internal combustion engine fueled with biomass gas from gasification is carried out using the software of AVL BOOST, which optimizes the internal combustion engine parameter of spark advanced angle and air fuel ratio.
