Abstract
An intake system has a tubular intake manifold, having an end connected to an intake port of an engine and an opposite end connected to a throttle body that includes a throttle valve. The intake system also has a bypass passage, connected to the intake manifold downstream of the throttle valve, and an air flow meter disposed in the bypass passage for detecting an amount of intake air drawn into the engine. A portion of the intake air that flows through the intake manifold is divided and flows into the bypass passage, wherein the amount of intake air flowing through the bypass passage is detected by the air flow meter.
