Though the DISC (Direct Injection Stratified Charge) engine has a good fuel consumption performance, it was not put into practical use. However, in 1996, Toyota Motor and Mitsubishi Motor began to manufacture it, and named it the D-4 Engine and GDI Engine, respectively. The development of fuel injection devices for the engine and an analysis of the combustion phenomena have been done in our laboratory with Toyota Motor. The new concept for the combustion system has been researched in our laboratory. The concept was applied to the 2nd generation D-4 Engine in 1998.
This magazine features the technology of the 2nd generation D-4 Engine. In this overview, the characteristics of the DISC Engine and progress of the development are described.
