| Summary: | This paper investigates about the rate of heat losses from through exhaust gas using exhaust gas calorimeter. A four stroke gasoline engine Magma 4G15 is used as a reference in this study. The engine simulation has been done using one dimensional GT-Power software and the simulation are at the various engine speed. The engine speed is varied for five different cases staring from 1000, 2500, 3000, 4500 and 6000 rpm at wide open throttle. The simulations are conducted with the purpose to test the applicability of exhaust gas calorimeter model in order to quantify the heat losses through exhaust gas. The model considered the calorimeter system components such as water reservoir, pipe for water in and out as a cold fluid and pipe connected from exhaust tail pipe to the calorimeter for the hot fluid. It is important to evaluate energy losses in the engine in order to increase the engine performance. The result showed that the rate of heat losses through the exhaust gas is increased with the increasing of engine speed. This is due to the fact that when the engine speed increase, the throttle opening will also increase in order to allow more mass of air entering the cylinder during combustion. Consequently, the mass of fuel also will be increased and affect the exhaust gas temperature. |
