Effect of ignition time on particle size and particle size distribution

Recommended Posts

Ignition time has little influence on the mixture formation of PI engine, but it has great influence on GDI engine. The C engine is mainly used for analysis. The bigger the ignition advance angle is, the shorter the mixing time and the more inhomogeneous the mixing will be. Therefore, the nucleate particles will increase the ignition advance angle and the quantity concentration will gradually increase. Because the oxidation rate and formation rate of particulate matter have little change with ignition advance angle, the change of aggregated particulate matter with ignition advance angle is not obvious. With the increase of ignition advance angle, nitrogen oxides emissions gradually increased, and CO and HC. gradually increased.
