This paper deals with penetration distance and mixture of gaseous fuel injected in a cylinder. When the fuel is jetted directly to the cylinder in a two-stroke engine, time from the jet to the ignition is short. Therefore, the time permitted to the mixture formation is also short, and it is important for forming the best mixture at the ignition to understand the fuel spray travel and the diffusion, etc. of the jet fuel. In this research, the Hythane gas direct injection two-stroke engine was assumed, and the state of the mixing or diffusion was analyzed with a model engine. As a result, it is cleared that sprayed gas fuel has weak penetration and is influenced to in-cylinder flow because the molecular weight of gaseous fuel is smaller in comparison with it of liquid fuel.
