Abstract
An engine control system comprises a coasting identification module, a throttle adjustment module, and a fuel adjustment module. The coasting identification module selectively identifies a coasting event. The throttle adjustment module increases an opening of a throttle valve during the coasting event. The fuel adjustment module decreases fuel provided to an engine during the coasting event.
