Abstract
An exhaust system for an internal combustion engine includes an air injection port in a designated region of an exhaust conduit having a converging-then-diverging nozzle providing increased exhaust gas flow velocity and decreased exhaust gas pressure. In another embodiment, an injection air conduit is connected between an alternator blower and the engine exhaust conduit to supply injection air to the latter.
