Abstract
A two-stroke cycle internal combustion engine has a quaternary Schnürle-type scavenging system that is configured such that the capacity of a pair of second scavenging passageways are made larger than the capacity of a pair of first scavenging passageways, so that during the descending stroke of the piston, air is allowed to be introduced into the combustion actuating chamber from the second scavenging passageways prior to the introduction of the air-fuel mixture and at the same time, a relatively large quantity of air is allowed to be introduced into the combustion actuating chamber from the first scavenging passageways over a longer period of time as compared with the period of time in which air is introduced from the second scavenging passageways.
