ABSTRACT:
A supercharged internal combustion engine which includes a turbocharger which includes a compressor and a turbine in communication with ambient air wherein that air is pressurized by the compressor to greater than ambient pressure. An intercooler, in communication with the outlet of the compressor, reduces the temperature of the greater than ambient pressure air. An intake manifold, in communication with the outlet of the intercooler, distributes the cooled and above ambient pressure air into an internal combustion engine. The internal combustion engine, which may be a diesel engine, a spark ignition gasoline engine or a direct ignition gasoline engine, is provided with an exhaust manifold in communication with the turbine of the turbocharger. A fuel metering means, introduces fuel into the internal combustion engine, such that the equivalence ratio of the mixture of fuel, provided by the fuel metering means, to air, provided by the intake manifold, is less than the equivalence ratio of an internal combustion engine at the smoke point or at an equivalence ratio operating at an equivalence ratio of about 0.85 to about 0.95. The supercharging parameter of air is greater than the supercharging parameter of air entering the internal combustion engine at the smoke point or at an equivalence ratio of between about 0.85 and about 0.95.
