Pilot injection timing
WebMay 12, 2024 · If the pilot injection time is short enough or the pilot injection/fuel mass ratio is large enough, the pilot injection creates an acceleration effect for the main injection. Although a shorter injection interval helped to form the acceleration effect, it performed worse in terms of the space utilization and thermo-atmosphere utilization.
