Abstract: An internal combustion engine includes an engine housing defining a cylinder, and a first and a second gas exchange valve for the cylinder, positioned within the engine housing. The engine further includes a valve actuating mechanism having a first and a second valve lifter reciprocating within adjacent lifter bores to actuate the first and second gas exchange valves. Each of the first and second valve lifters includes an end cap having a misalignment limiting projection, limiting rotation of the valve lifter in response to dynamic perturbation.

Abstract: The two-stroke engine has a plurality of intake passages extending from the external air inlet port through the crankcase, separating the intake air charge from the air and oil vapor within the crankcase. The piston has one or more corresponding inlet tubes depending therefrom that telescope within the crankcase intake passages as the piston reciprocates. All intake air travels through these passages and is separated from the remainder of the crankcase volume. The incoming air charge passes through a concentric poppet valve in the piston crown to enter the combustion chamber. Fuel is provided by conventional direct or port injection and ignition is provided by one or more conventional spark plugs. Diesel operation is achievable when the engine is configured appropriately. Exhaust exits the combustion chamber through a poppet valve in the cylinder head, the poppet valve being actuated by a rocker arm and pushrod from a crankshaft driven cam.
