Abstract

This paper describes a study an influence of ethanol concentration in premium-ethanol fuel blends on vehicle performance and exhaust gas emissions. The study is based on the vehicle test on chassis dynamometer. Exhaust gas emission was measured on idle condition and using ECE standard regulation No. 83-04. Three compositions were performed on the first step, which are 3%, 10% and 20% of volume. Performance and emission results were compared to the test results on the same vehicle fuelled with 100% premium and pertamax. The test results have shown that increasing concentration of ethanol will increase torque and power, reduce CO and HC emission, except on idle condition. 10% ethanol concentration have identical performance characteristic with the same vehicle fuelled with pertamax, with 60% less CO emission on idle condition and 30% less when using ECE 83-04 standard.

Abstract

An engine performance can be predicted through modeling and simulation programs. This paper describes the cycle modeling and breathing process of a four-stroke diesel engine. Calibration of the model parameters to eliminate prediction error. This calibration requires the definition of empirical correlation of two parameters namely mechanical delay and the injector nozzle discharge coefficient. Modeling validation is also given by presenting the result data and evaluating the output parameters of the engine. The result of the diesel engine in-cylinder model produces good predictions by applying a mechanical delay correlation for correction of injection time and correlation coefficient of discharge nozze injector. The parameters for correction of injection duration where the mean temperature and pressure conditions for the duration of the injection are used as input model ignition delay cylinder.Keywords: Modeling, Diesel Engine, Performance, Ignition Delay, Emissions

Abstract

The depletion of petroleum reserves as the basic raw material for gasoline production has driven studies into alternative fuels. One of the alternative fuels is alcohol, both ethanol and methanol. Due to their liquid form and physical-chemical properties similar to gasoline, small modifications to the engine are required. This paper will explain the effect of using a mixture of gasoline (in this case, RON 98 gasoline with methanol or methanol on engine performance and emissions. The fuel mixtures are as follows: G100, E10, E20, E30, M10, M20, M30. AVL Boost simulation software was used as a tool for 1-dimensional engine modelling, where the modeling is based on engine testing with G100 fuel. The results show that with increasing ethanol-methanol composition, torque and power decrease, and SFC increases. On the emission side, CO, CO2, and HC were decreased and NOx increased.
