摘要
Optimized alcohol and plasma enhanced prechambers for engines powered by gasoline and other fuels are used to increase the range of prechamber operation and to reduce soot. The increased prechamber capability is employed to extend the limit of lean operation of the engines. It can also be used to extend the limit of heavy EGR operation and to enable higher RPM operation. The amount of alcohol used in the prechamber is preferably less than 2% of the fuel that is used in the engine cylinder. The alcohol for the prechamber can be entirely provided by onboard separation from a gasoline-alcohol fuel mixture.
