In order to improve the performance of a two-stroke hydrogen injection engine, it is necessary to clarify the scavenging characteristics with the supercharging taken into account. In the present study, the gas in the cylinder before combustion was sampled and analyzed to obtain the contents of H_2 and O_2 molecules. On the other hand, by using the chemical reaction theory, a theoretical equation with H_2 and O_2 contents as variables was derived to obtain the scavenging efficiency and the trapping efficiency. Applying this theory to the experimental results with a practical operating hydrogen fueled engine, the scavenging characteristics have been evaluated. Also, the effects of mechanical supercharging and turbocharging on the two-stroke engines were investigated both theoretically and experimentally. As a result, is was found that supercharging was practically effective for increasing the output power.
