Abstract:
A method of increasing a flow rate of a flow of intake air to an engine, said engine defining a plurality of speeds, one of said plurality of speeds being a low speed and another of said plurality of speeds being a high speed, said engine further including at least a turbocharger, said steps of increasing said flow rate of intake air to said engine comprising;directing said flow of intake air to a turbocharger;compressing and densifying said flow of intake air within said turbocharger;monitoring said flow rate of intake air to said engine;monitoring a quantity of fuel to said engine;calculating a proportional relationship of said quantity of fuel to said flow rate of intake air;directing said flow of intake air from said turbocharger to at least one of a directional control valve and a supercharger depending on said calculating said proportional relationship;driving said supercharger with a motor;compressing and densifying said flow of intake air having passed through said turbocharger further within said supercharger; anddirecting said compressed and densified flow of intake air from said supercharger through said directional control valve prior to directing said increased flow of intake air to said engine.
