ABSTRACT:
An energy recovery system for a motor vehicle having a gasoline engine and an exhaust energy recovery device disposed in an exhaust system of the engine. When the amount of depression of an accelerator pedal is zero and the speed of travel of the motor vehicle and/or the rotational speed of the engine is higher than a predetermined value, it is decided that an engine brake is applied to the motor vehicle at the time the motor vehicle is decelerated or runs down a slope. Then, fuel to be supplied to the engine is cut off, and the throttle valve is fully opened. As a result, the engine functions as a compressor, and air compressed by the engine operates the exhaust energy recovery device. The braking energy produced by the engine brake is now effectively converted into and recovered as electric energy.
