Abstract: A compound engine including a gas turbine unit and a two-stroke uniflow scavenge piston unit having a hollow cylindrical exhaust valve mounted concentrically with an associated piston to form a portion of the combustion chamber within a peripheral wall of the exhaust valve. A double acting exhaust valve actuator is responsive to rotation of the crankshaft and is operatively coupled to the peripheral wall of the hollow cylindrical exhaust valve to produce forces derived directly from rotation of the crankshaft to open and close the exhaust valve. The actuator is a camshaft having two sets of cams which drive a cam follower in response to rotation of the crankshaft.

Abstract: A two-stroke engine has a piston operatively connected to a crankshaft for reciprocating motion within a cylinder. An annular piston valve is mounted for slidable motion with respect to a centrally located inner body of the piston to control a flow of cycle air through the piston. A cycle air intake opening is located in a wall of the cylinder at a location above a bottom dead center position of the piston. The cycle air intake is blocked and unblocked by the reciprocating motion of the piston. A transition member located between the crankcase and the cylinder has a bore for sealingly receiving the straight body section of the connecting rod.
