文摘

Fuel physical effects on the split injection strategies are numerically studied. The injection mass and pressure propagation at the injector inlet are investigated. Effects of each individual fuel physical property are isolated. Effects of fuel density and bulk modulus of compressibility are more pronounced. Injection dwell time is a crucial parameter influencing the main injection event.
