Abstract

This paper describes a study that compared performance and emission from a 97 cc small single cylinder gasoline engine using five differences carburetor jet configuration. The study is based on the engine test bed results. The test results have shown that the bigger main jet produce slightly higher torque and power than the smaller one, but the fuel consumption also higher. The emission test results have shown a higher hydrocarbon (HC) and carbon monoxide (CO) for bigger main jet configuration. However Oxide of Nitrogen (NOx) emission from bigger main jet configuration was generally lower. The smallest jet configuration produced to lean fuel air mixture and caused engine over heat. The data obtained in this study indicate that the best configuration for the engine tested is 72/38 jet configuration.

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.
