Combustion system for gas engine other than dual fuel engine

An improved combustion system for an internal combustion engine having at least one cylinder wherein said at least one cylinder has operatively connected thereto a piston, at least one inlet valve, at least one exhaust valve, a fuel torch cell, and a first fuel injector with said torch cell being adapted to be operatively connected to said at least one cylinder, said system including:

• an auto-ignition chamber defined by said torch cell and having a torch cell nozzle at one end thereof and the other end having appropriate means to connect a fuel injector mounted in said torch cell, with said fuel injector being in operative communication with said auto-ignition chamber and having a plurality of orifices opening into said chamber, a glow plug extending into said torch cell and chordally spaced from and aligned with one of said orifices, and a touch nozzle passage connecting said auto-ignition chamber with said cylinder at a predetermined angle to a top inner portion of a cylinder head closing said cylinder, and wherein said fuel injector and said glow plug extend into said autoignition chamber in generally aligned but spaced relation, further, said fuel injector has one of said orifices adapted to inject fuel into said chamber in a generally axial direction while a second of said orifices is adapted to spray fuel in the direction of said glow plug, with said fuel injector being provided with means for controlling the direction of said second orifice, further, wherein said engine utilizes a low cetane gaseous fuel mixture.
