ABSTRACT:
A two-stroke cycle gasoline engine including at least one two-stroke cycle power cylinder - piston assembly incorporating uniflow scavenging and two horizontally opposed pistons, and a scavenging structure which gives zero or a relatively weak swirl to the scavenging mixture ejected into the power cylinder so as to effect stratified scavenging of exhaust gases when the engine is operating at relatively low load and which gives a relatively strong swirl to the scavenging mixture ejected into the power cylinder so as to cause high turbulence in the mixture when the engine is operating at relatively high load.
