ABSTRACT:
An engine system includes an intake manifold, and an air inlet enabling an air flow into and out of the intake manifold. An air flow sensor is attached to the air inlet, and measures a flow of air through the air inlet. A first sensor is also included, and is operable to determine a direction of air flow. The air flow sensor is in communication with a controller, which records the mass of air flow through the air inlet. In one embodiment, the first sensor is a differential pressure that detects a pressure differential. In an alternative embodiment, a second sensor communicates with the air inlet, and the first sensor communicates with the intake manifold. The first and second sensors jointly determine a direction of air flow. In yet another embodiment, an output of the first sensor is compared to a calibrated barometric pressure to determine a direction of air flow.
