ABSTRACT:
An improved lean charge fuel ignition system for use with internal combustion engines and is conceptually based on the stratified charge condition. This system has a fuel igniter mechanism which includes a pair of passages formed in one of the electrodes of the fuel igniter. Enrichment fuel is injected into the neighborhood of a spark gap which is in a secondary chamber containing a lean fuel-air mixture. Upon ignition of the resulting enriched mixture a flame front propagates to the engine cylinder chamber where ignition of the lean mixture of fuel and air is initiated. The second passage formed within one of the electrodes of the fuel igniter means is connected to a fuel injection device which includes a spray pump actuated by the standard cycling pressures formed within the engine cylinder chamber to provide necessary metering and flow of enrichment fuel through the second passage of the electrodes into the neighborhood of the spark gap.
