ABSTRACT:
A dual cold air induction (“DCAI”) system, apparatus and method for decreasing the intake air temperature, which increases the air's volume and efficiency, at the diesel internal combustion engine's point-of-ignition. The DCAI system comprises a dual air cooling unit defined by primary and secondary compartments. The primary compartment ingests ambient air and conditions it to a preset predetermined temperature for mixing with ambient air upstream of the turbocharger's compressor side. The conditioned ambient air, located on the turbocharger's compressor's downstream side, is further conditioned in the secondary compartment to a preset predetermined temperature which is then delivered to the engine intake. The housing, which houses a plurality of air cooling components for producing cold air, has insulative capabilities for maintaining the cold air temperature created within both compartments of the housing. An expansion valve and an expansion block valve are provided for regulating the refrigerant's flow into both compartments.
