An improved combustion system for an internal combustion engine is disclosed wherein a rich air/fuel mixture is furnished at high pressure to one or more jet plume generator cavities adjacent to a cylinder and then injected through one or more orifices from the cavities into the head space of the cylinder to form one or more turbulent jet plumes in the head space of the cylinder prior to ignition of the rich air/fuel mixture in the cavity of the jet plume generator. The portion of the rich air/fuel mixture remaining in the cavity of the generator is then ignited to provide a secondary jet, comprising incomplete combustion products which are injected into the cylinder to initiate combustion in the already formed turbulent jet plume. Formation of the turbulent jet plume in the head space of the cylinder prior to ignition has been found to yield a higher maximum combustion pressure in the cylinder, as well as shortening the time period to attain such a maximum pressure.

An improved combustion process for an internal combustion engine which comprises: a) providing a lean air/fuel mixture to a cylinder of an internal combustion engine; b) injecting an unignited rich air/fuel mixture at a pressure exceeding the pressure in said cylinder into at least one generator cav

An improved combustion process for an internal combustion engine which comprises: a) providing a lean air/fuel mixture to a cylinder of an internal combustion engine; b) injecting an unignited rich air/fuel mixture at a pressure exceeding the pressure in said cylinder into at least one generator cavity adjacent said cylinder so that said rich air/fuel mixture will flow from said cavity into said cylinder through at least one orifice in said at least one generator cavity to form a jet plume of such rich air/fuel mixture in said cylinder which entrains said lean air/fuel mixture therein; c) igniting, in said cavity, portions of said rich air/fuel mixture remaining in said cavity after said high pressure injection; and d) injecting through said orifice into said cylinder the incomplete combustion products generated in said cavity, triggered by said ignition in said cavity, to initiate combustion in said cylinder of said rich air/fuel mixture previously injected into said cavity and said lean air/fuel mixture entrained in said rich air/fuel mixture.
