Four different fuels, three different content of biodiesel （BD20, BD50 and BD100） and light oil, were prepared and tested in the four strokes diesel engine. Power output, fuel consumption rate and exhaust gases of the four fuels in the diesel engine were compared and discussed. Power output of light oil engine was the greatest showing 5.3% difference between light oil and BDI00. But, almost no power difference between light oil engine and BD20 engine, light oil engine produced 0.37% more power than BD20 engine superior to better power than BD20 engine. Less exhaust gases of CO2, CO, NOx and total hydrocarbon （THC） were produced from animal fats biodiesel than light oil, which confirmed that biodiesel is environmental friendly fuel. For fuel adoptability in the tractor, biodiesel engine tractor showed its fuel competitiveness comparing with light oil for tractor works in the paddy field.展开更多
This work examines the effect of fuel temperature in the gas emissions that is used in a four-stroke diesel engine under maximum constant fuel consumption. The fuel temperatures that were used are 20 ℃, 30 ℃, 40 ℃,...This work examines the effect of fuel temperature in the gas emissions that is used in a four-stroke diesel engine under maximum constant fuel consumption. The fuel temperatures that were used are 20 ℃, 30 ℃, 40 ℃, 50 ℃, 60 ℃, 70℃ and 80 ℃. The engine was functioned under full load condition when it was using different mixtures of diesel-palm oil as fuel. For those fuel temperatures and for any mixture of fuel the gas emissions of carbon monoxide （CO）, hydrocarbons （HC）, nitrogen monoxide （NO） and rotate speed of engine are examined.展开更多
