Abstract
An air induction system is disclosed for an engine that comprises an air cleaner, an inlet air conduit, a Mass Air Flow Sensor (MAFS), and a secondary air induction system. The air filter encloses a filter element that removes contaminants from the air supplied to the engine. A MAFS is disposed in the inlet air conduit and measures the mass of the air flowing through the inlet air conduit to an intake manifold of the engine and provides data to an engine control module that controls the air/fuel mixture supplied to the engine. The secondary air system receives air from the air cleaner that is provided to a vehicle component and includes an inlet port located upstream from the MAFS. The secondary induction conduit draws air through a port integrated with the MAFS bore with an air pump to provide clean air to an engine component or exhaust system component.
