Such vehicles in Beijing more than 5 million cars city, PM2.5 particle pollution, most from automobile emission. Especially in the idle state, PM2.5 emissions of pollutants is smooth driving more than five times. In idling process of tail gas pollution and fuel waste, some European auto makers such as Benz BMW started developing the idle stop intelligent fuel system, eliminate idle while waiting in the harmful gas emissions and oil saving effect achieved good results. According to statistics, in the big cities of China general road idle speed stopping time ratio reached 10%, main road even as high as 50% above. Using the idle start-stop intelligent oil saving system in general traffic conditions can save 8% of the fuel, but in the congestion in the section of the highest can save about 15% of fuel, is of great significance for consumers. This paper discusses the intelligent oil saving system functions, characteristics, main structure, working principle and daily use, through to the intelligence of the fuel system parts design improvement, make it better adapt to the day-to-day use, at the same time, this paper discusses the intelligent oil saving system of systematic, modular design method, and intelligent oil saving system of intelligent control, and an example is introduced to make simple.
