Abstract
The concept of JPIC (Jet Plume Injection and Combustion) is introduced as a radical refinement of DISC (Direct Injection Stratified Charge). The system for its implementation consists of a fuel injector and a PJC (Pulsed Jet Combustion) generator (described in our previous papers) connected in series via a check valve. In operation, rich air-fuel mixture is admitted thereby first to a lean charge in the cylinder, forming a turbulent jet plume, and, thereupon, the process of combustion is executed using a pulsed jet of combustion products created upon ignition, by means of a conventional spark discharge, of the mixture remaining in the cavity of the PJC generator. Charge stratification thus obtained affects not only chemical composition, but also the scale and intensity of turbulence. The latter is, under such circumstances, associated with a significant amount of entrainment due to the large scale vortex structure of the turbulent plume. Experimental tests of JPIC systems, carried out in a constant volume enclosure, demonstrate the advantages of such stratification over the PJC mode of combustion we determined previously.
