一、内燃机发展概况内燃机是热效率最高的热能动力机械。１９９７年产量按功率计近２亿ｋｗ（其中面广量大的中小功率内燃机占９７％），超过当年发电设备产量的１０倍。全国内燃机保有量达９～１０亿ｋｗ。改革开放以来，我国从国外引进了先进的内燃机产品、装备及成套技... First, the internal combustion engine development Overview Internal combustion engine is the thermal efficiency of the highest thermal power machinery. In 1997, the output was nearly 200 million kw by power meter (of which 97% were medium-sized and small-sized internal combustion engines with a large surface area), more than 10 times of the power plant output of that year. National internal combustion engine to maintain the amount of 9 to 1 billion kw. Since the reform and opening up, our country has introduced advanced internal combustion engine products, equipment and complete sets of technology from abroad.
