Abstract:
1. An internal combustion engine comprising: a) an engine having one or more combustion chambers; b) a compressor for receiving an air-fuel mixture and compressing the air-fuel mixture to form a compressed air-fuel mixture; c) a heat exchanger associated with the internal combustion engine; d) a control valve associated with the internal combustion engine; e) first and second outlets extending from the compressor wherein the first outlet is operative to direct a first stream of compressed air-fuel mixture to the control valve and the second outlet is operative to direct a second stream of the compressed air-fuel mixture to the heat exchanger where the second stream of compressed air-fuel mixture is heated and thereafter directed to the control valve; f) a controller operatively associated with the control valve for sending a signal to the control valve and causing the control valve to mix the first and second streams of compressed air fuel mixture together after the second stream of compressed air-fuel mixture has been heated; g) and wherein after the first and second streams of compressed air-fuel mixture have been mixed, the combined streams of compressed air-fuel mixtures is directed into one or more of the combustion chambers; h) a temperature probe positioned in an intake manifold of the internal combustion engine for sensing the temperature of the combined streams of compressed air-fuel mixture; and i) the controller configured to: (1) receive a temperature signal from the temperature probe that is indicative of the sensed temperature, (2) compare the sensed temperature with a set point temperature, and (3) generate an actuating signal and directed the actuating signal to the control valve where the actuating signal commands the control valve to a required setting for causing the temperature of the combined compressed air-fuel mixtures reaching the one or more combustion chambers to be at or near the self-ignition temperature of the fuel that forms a part of the combined compressed air-fuel mixtures.
