Pilot injection of fuel occurs
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. WebFuel injected during pilot injection depends on the injection pressure and on the pilot injection duration; for the present study, injection pressure was kept almost constant for …

WebNov 24, 2013 · The compression ignition event takes place by injecting fuel into the combustion chamber when the piston is close to the Top Dead Center (TDC) position. The hot air in the cylinder causes the fuel to vaporize. At first, a very small portion of the fuel vaporizes and begins to ignite.
