Abstract
An exhaust gas reflux mechanism for a multipurpose engine includes an exhaust reflux cam formed as an integral part of an single cam of the engine and having a cam lobe profiled to open an exhaust valve while an intake valve stays open during the intake stroke of the engine so that part of an exhaust gas remaining on the side of an exhaust port of the engine is drawn into a combustion chamber during the intake stroke.
