Abstract
A two cycle interal combustion engine constituting of upper exhaust ports and a lower exhaust port provided on the upper and the lower of the level of the upper edge of scavenging ports, respectively, and having only the upper exhaust ports connected to a cleaning device. As a result of that, exhaust gas containing large amounts of hazardous components is mainly discharged from the upper exhaust ports and, because the exhaust gas can be cleaned concentratively, the decontamination efficiency of exhaust gas is good.
