Recently CO₂ emission regulation has become more stringent and higher thermal efficiency of the internal combustion engine is required. Spray-guided gasoline direct injection engine has promising potential for lower fuel consumption. The purpose of this study is to clarify the air-fuel mixture formation requirements and to investigate the spray specification of multi-hole nozzle injector for spray-guided stratified combustion.

A new display technology is presented in order to improve the value of automotive systems which use displays; such as navigation systems and future communication systems. Displays are becoming crucial to making the systems complete and user-friendly. A full-color antiferroelectric liquid crystal display has been developed featuring excellent display image quality and wide viewing angle characteristics. The antiferroelectric liquid crystal display has a completely different operation principle from any other LCD and makes it possible to realize image quality which is comparable to TFT-LCDs with a simple matrix structure.
