Abstract

Engine fuel is the foundation of the national economy, and engine fuel demand is increasing, with the social and economic development, increasing national dependence on diesel and gasoline. International oil prices fluctuated between more than 50 U.S. dollars and 147 U.S. dollars in 2008 and 2009. Of the oil-poor countries, reduce dependence on foreign oil is a colossal problem. No. 0 diesel based on ethanol and pressed peanut oil, mixed fuel preparation 0 # diesel ethanol peanut oil (50 ︰ 8:2, 10). Mainly carried out in the course of the experiment the following experiments: preparation of 0 # diesel ethanol peanut oil mixed oil; 2 test 0 # diesel ethanol peanut oil physical characteristics; 30 # diesel ethanol peanut oil bench test; 40 # diesel ethanol peanut oil load characteristic curve; 50 # diesel ethanol peanut oil smoke emissions and exhaust components analysis. The results showed that: 0 # diesel ethanol peanut oil temperature of -35 ℃ and 80 ℃, turbidity and stratification. The Engler viscosity values ??of 0 # diesel ethanol peanut oil (1.3970E) below 0 # diesel (1.660E), flash point (98.97 ℃) is higher than 0 # diesel oil (58 ° C), density (842.5kg / m3) below 0 # diesel (930 kg / m3), ignition (114.73 ℃) below 0 # diesel oil (220 ° C). 0 # diesel ethanol peanut oil compared to 0 # good atomization of diesel in the combustion process in the ignition delay period is short, full fuel combustion, maximum pressure rise during the rapid burning ratio to below 0 # diesel pressure higher than , the combustion process is stable, the emissions of CO and CH reduced NOx content increases. 0 # diesel ethanol peanut oil in ZH1100B diesel engine combustion in high-load conditions, 0 # diesel ethanol peanut oil and 0 # diesel peanut oil and 0 # diesel fuel consumption rate of fuel supply advance angle of 16.8 ° (no spacers), there is no obvious changes in the small-load conditions, 0 # diesel ethanol peanut oil and 0 # diesel fuel consumption rate and fuel consumption of peanut oil is higher than 0 # diesel. Fuel supply advance angle of 13.3 °, 0 # diesel ethanol peanut oil, 0 # diesel peanut oil and 0 # diesel fuel consumption in the high-load changes significantly, due to the peanut oil and ethanol as an oxygen-containing raw materials, fuel use 0 # diesel ethanol peanut oil and 0 # diesel peanut oil, the economy is good. 0 # diesel ethanol peanut oil used in the diesel engine fuel supply advance angle of 13.3 ° diesel economy better than oil supply advance angle of 16.8 ° engine economy. 0 # diesel ethanol peanut oil and 0 # diesel peanut oil ZH1100B burning diesel engine emissions of 0 # diesel. Since ethanol and peanut oil is fully oxygenated raw materials, combustion, opacity value is small, low smoke. When a load of 6.5kW about the maximum opacity value. 0 # diesel, ethanol and peanut oil used in the diesel engine, fuel supply advance angle of 16.8 ° diesel exhaust PM value better than oil supply advance angle of 13.3 ° diesel exhaust PM value.
