Development of Multi-hole Nozzle Injector for Spray-guided DISI Engine

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.
