ABSTRACT:
An internal combustion engine (20) has a plurality of pistons (106) reciprocating within cylinders (34) and means to translate the reciprocating motion of said pistons into rotary motion. As the cylinders (34) rotate in an engine cavity (49) about a drive shaft (24), head ends (104) of the cylinders (34) cyclically pass stationary fuel injection means (28) and a stationary exhaust aperture (30) located rotationally downstream from the fuel injection means (28). Each cylinder (34) includes a cylinder wall having an air intake port (130) provided therein. The air intake port (130) is provided at a location at which rotation of the cylinder (34) in the cavity (49) tends to force or scoop air into the cylinder (34). In particular, the air intake port (130) is provided on a rotationally leading portion of a peripheral portion of the cylinder wall. The air intake port (130) of the cylinder is opened after alignment with the exhaust port (30) has commenced but before the piston (106) in a chamber (34) reaches its extreme point of travel. As the air intake port (130) is thusly opened, ambient air from the engine cavity (49) is forced into the air intake port (130) by rotational motion of the cylinder (34). Thus, with the cylinder (34) registering with the exhaust port (30), the rotational motion of the cylinder (34) forces or scoops ambient air from the engine cavity (49) into the air intake port (130), through the interior or the cylinder (34), and through the exhaust aperture (30) for scavenging the cylinder assembly (34).
