described further the egr gas may be sent through a fuel injector 104 in particular a gas assist fuel injector 104 gas assist fuel injectors are configured to pass a stream of high pressure gas therethrough fuel in particular liquid fuel such as diesel gasoline and the like is received by the fuel injector 104 which causes the fuel to enter the stream of gas the gas assisted fuel then atomizes prior to entry into the combustion chamber it is noted that the fuel injector 104 may be configured for injection into an intake port not shown or directly into the combustion chamber 102 the egr gas may pass through a compressor 108 prior to entering the fuel injector 104 gas assist injectors typically require the gas to enter under pressure high enough to overcome the pressure in the combustion chamber 102 although the egr gas may have enough pressure initially it may be required under some engine operating conditions to compress the gas still further in the preferred embodiment the egr gas passes through a temperature control unit 106 prior to entering the fuel injector 104 an elevated temperature of the gas is desired for the present invention preferably the temperature of the gas as it enters the fuel injector 104 is within a range from about 100 degrees celsius to about 500 degrees celsius more particularly it is preferred that the temperature of the gas is within a.
