Abstract
An exhaust system of an internal combustion engine comprising an ejector provided in the exhaust pipe of the engine and a compressor driven by the engine. Pipes are provided for selectively supplying compressed air to a nozzle of the ejector and to the intake pipe of the engine by operating valves. The exhaust pipe of the engine is communicated with an exhaust pressure reducing chamber of the ejector. The valves are adapted to be operated by the throttle valve of the engine and are so arranged that the compressor is communicated with the ejector in part-open throttle operation and with the intake pipe in wide-open throttle operation.
