| Popis: | In this study, the effect of nitromethane addition to gasoline fuel on engine performance and emissions in a single-cylinder spark-ignition engine was experimentally investigated. By adding 5% and 10% nitromethane to gasoline, experiments were carried out at full load at six different cycles. Engine load, fuel consumption, exhaust gas temperature, and emissions were measured during the experiments. According to the measured experimental data, engine power, torque, specific fuel consumption, exhaust gas temperature, average effective pressure, thermal efficiency, CO, CO2, HC, and NOx values were compared with each other. According to these results, nitromethane's addition improved engine power, torque, specific fuel consumption, and thermal efficiency. It is understood that the addition of nitromethane to gasoline improves combustion efficiency and increases thermal efficiency. With the addition of nitromethane, an increase in CO2 emission, which is a product of complete combustion, and a decrease in CO emission occurred. This supports the increase in combustion efficiency. HC emissions have decreased. There has been an increase in NOx emissions. In addition, since the addition of more than 10% nitromethane causes knocking, it has created difficulties in using it without modification in the engine. |
