Abstract
Past air intake systems have failed to effectively and efficiently utilize the arrangement of structural components to increase boost at low engine speeds. The present air intake system effectively and efficiently utilizes the arrangement of structural components to increase boost at low engine speeds. The air intake system directs intake air through a turbocharger and evaluates the quantity of flow of intake air to the engine as compared to the flow of fuel. And, depending on the results of the evaluation, a directional control valve directs the flow of intake air to a supercharger or to the engine. The supercharger is driven by a motor having a variable rate of speed as compared to the engine.
