| Abstract: | A study of a direct fuel injection 2-stroke engine as a new generation power unit was performed and concluded as follows. - 1.(1) A comparison of fuel injection system candidates was made and the one-fluid high-pressure type was chosen.
- 2.(2) Adopting the high-pressure fuel system to a single-cylinder engine, stratified charge combustion was realized using the late injection.
- 3.(3) It was found that homogeneous charge combustion using the early injection would enable high power output.
- 4.(4) The “2-zone combustion” was also achieved by injecting the fuel twice within one cycle.
