Summary:

The authors have been engaged in developing a new-generation two-stroke gasoline engine which could be employed ultimately for automobiles. By investigating the defects of the Schnurle-type two-stroke gasoline engine, a reverse uniflow-type direct injection engine has been developed and built. The newly introduced system employs stratified charge combustion in light to medium load conditions by using the technology already developed for the four-stroke direct injection gasoline engines while it can supply the maximum power output by using a super-charger and attaining homogeneous combustion. Engine performance is being tested experimentally. In order to analyze the performance test results, numerical analysis of in-cylinder phenomena, such as gas-exchange, gas motion, fuel spray formation, and mixture formation is carried out in this paper. As a result, it was found that the interaction between in-cylinder gas motion and spray motion is a very important factor to improve the combustion performance, depending on both the engine speed and engine load
