This paper deals with an in-cylinder direct injection two-stroke engine. Generally, two-stroke engine with a carburetor cannot prevent the short-circuit loss of fuel at the gas exchange process. Therefore, it is bringing about problems to discharge the hydrocarbon and to get worse fuel consumption etc. As their solution, a fuel direct injection is very effective. In the gasoline direct injection, vaporization and mixture of fuel and air are very important. In this investigation, combustion chamber with squish area and the piston with hemispherical depression on the top are adopted to concentrate good mixture gas around the spark plug. As a result, the emission ratio of the hydrocarbon and the NOx decreased in comparison with a carburetor.
