The supercharging characteristics and the combustion performance of the spark iginition engine are investigated through the experiments. The apparatuses used in the experiment are the carburetor type 1468cc Gasoline Engine and the screw type supercharger. A supercharger pulley and a water pump pulley through V-belt are connected to the engine. The diameter of supercharger pulley is 63mm. The diameter of water pump pulley used are 63mm and 135mm,repectively.A optical senser is used to measured the speed of a engine. The pressure in first cylinder is measured. The rate of pressure rise and the rate of heat release are calculated. The engine speed considered is increased by 500rpm from 1500rpm to 3500rpm. It is found that the supercharging characteristics and the combustion performance in case of the engine with supercharger are increased at low speed range. Compared the supercharged engine with the natually aspirated engine, the most effects of supercharging on the torque and the rate of maximium pressure rise are observed at 2000rpm and 1500rpm, respectively.
