얀마디젤기관용 분사밸브 형상에 따른 분사특성 분석

Injection technology is one of the important technologies in a diesel engine. Many studies have done on the injection system. In this study, the fuel chamber geometry, the orifice ratio and the needle lift are tested in the injection valve for Yammar diesel engine. The result shows that the nozzle hole size has influence on the rail pressure and injection duration sensuously.
