Active scavenge prechamber

摘要: In certain embodiments with large size prechambers and/or that have spark-gap electrode assemblies, a poor scavenge of the crevice volume may cause deterioration preignition margin, which then limit power rating engine, flow velocity field fuel-air mixture to be excessively uneven and result in misfire limit. One or more auxiliary scavenging ports allow admission fuel rich volume, thereby cooling residual gases preventing occurrence preignition. More organized powerful fields obtained assembly region. This condition significant extension flammability significantly improve combustion efficiency prechamber. Passive using active concept increase engine output reduce emission pollutants from combustion.
