Aqueous Ethanol Gasoline Efi Gasoline Engine Performance And Combustion Characteristics

Energy, environment, agriculture, population and employment is the impact of global economic and social sustainable development. How co-ordination to address the above problems have been caused by the domestic and the international community's attention. The development and application of fuel ethanol and motor gasoline to promote the use of ethanol, to alleviate the above problems will be one of the effective ways, the meaning of the concept of scientific development to actively explore.First, the subject of access to a large number of the fuel ethanol and motor gasoline ethanol research, promotion and use of information, based on summarized and concluded that demonstrates its feasibility.To Chery's SQR481F EFI gasoline engine for the study, carried out by burning E10w, E20w, E30w water content of ethanol and 93 # gasoline Comparative Experimental Study on gasoline. The experimental results show that:power, the fuel moisture content of ethanol with gasoline is lower than its dynamic 93 # gasoline, and with the increase of ethanol content in a downward trend; in the economy is concerned, in line with the characteristic curves showed that the effective higher rate of fuel consumption, and with the increase of ethanol content increased to the equivalent calorific value of fuel consumption rate of less than 93 # gasoline, and with the ethanol content increasesEmission rate and the catalytic converter, fuel moisture content of ethanol with petrol in small and medium-sized load of CO changes the scope of basically the same, and lower than the 93 # gasoline, improving the load in the more obvious effects. In HC emissions, the entire load range was improved. NOx emissions in the medium and small load more obvious improvement, in little change in load. CO, THC and NOx emissions along with the increase of ethanol content, the more obvious improvement. The product of their emissions with catalytic converters in the conversion efficiency with engine speed, load and the content of ethanol, EFI gasoline engine in the SQR481F followed by burning 93 #, E10w, E20w, E30w, E50w aquifer was burning ethanol gasoline data (cylinder pressure, the pressure rise rate and its associated data), and through the above-mentioned data and indicator diagram of the comparative study found that:the maximum cylinder pressure and maximum rate of pressure rise along with the increase of ethanol content decreased; maximum cylinder pressure crank angle, as well as the corresponding increase in the rate of maximum pressure along with the ethanol content increases.
