| Abstract: | Supercharging of intake air can improve the engine power and combustion characteristics by boosting the intake pressure above
atmospheric pressure. In this work, the supercharging performance of a supercharged gasoline engine was discussed on the basis
of experimental investigation. The investigation results showed that the output and torque performance of a supercharged engine
were improved in comparison with the naturally aspirated engine. In the engine system with a supercharger, owing to supercharging
of intake air into the cylinder, the combustion pressure, the rate of heat release, and the burning rate of fuel-air mixture
were found to be higher than those of the naturally aspirated engine. In this paper, the effect of the drive pulley ratio
and the pressure ratio of supercharger, and the other factors on the supercharging performance were also investigated. |
