今天,汽油发动机的数量多,用途广泛,特别是在汽车上,如何既能节省汽油,又要减少排放物质对生活环境造成的污染,是人们普遍关心的一个问题。国内外对于汽油掺水在发动机上的应用与研究、曾有过较长一段历史。近年来由于石油供应紧张,加上环境污染问题的提出,对发动机的排放物质有严格的限制,于是汽油掺水措施在很多地方又重新采用。已有的一些试验结果表明,如果发动机运行条件合适,汽油掺水这一技术措施可以取得 Today, there are many gasoline engines with many uses, especially in the automobile industry. How to save gasoline and reduce the pollution caused by the pollutants to the living environment is a common concern. At home and abroad for gasoline dosing in the engine on the application and research, there have been a long history. In recent years due to tight oil supply, coupled with the issue of environmental pollution, the emission of the engine material has strict restrictions, so gasoline blending measures in many places and re-use. Some of the existing test results show that if the engine operating conditions are suitable, the technical measure of gasoline blending can be obtained
