    Abstract: An engine assembly includes an engine block that defines a cylinder bore. A reciprocating piston is disposed in the cylinder bore, and has a first side and a second side. The first side cooperates with the engine block to partially define a combustion chamber, and the second side is opposite the first side. A piston squirter is disposed adjacent to the second side of the piston and configured to expel a received flow of engine oil onto the piston. A thermal fluid valve is disposed in fluid communication with the piston squirter and is configured to selectively restrict the flow of engine oil to the piston squirter in response to a temperature of the engine oil.

    Abstract: An engine assembly includes a two-cylinder engine, an intake assembly, and an air-oil separator. The two-cylinder engine defines a first cylinder bore, a first combustion chamber, a second cylinder bore, a second combustion chamber, and a crankcase volume. The engine further includes a first piston disposed within the first cylinder bore, and a second piston disposed within the second cylinder bore. The intake assembly includes an intake manifold in fluid communication with each of the first and second combustion chambers, and the air-oil separator defines a separator volume and in fluid communication with each of the crankcase volume and the intake manifold. A reciprocal, synchronous motion of the first and second pistons is operative to exhale gas from the crankcase volume through the separator volume and into the intake manifold.

    Abstract: A camshaft-drive tensioner system is disclosed for an internal combustion engine having a camshaft-drive element. The camshaft-drive tensioner system includes a tensioner configured to be energized by a pressurized fluid in order to apply a force to the camshaft-drive element. The camshaft-drive tensioner system also includes a fluid pump configured to supply the pressurized fluid. The camshaft-drive tensioner system additionally includes a controller configured to regulate either volume or pressure of the fluid supplied to the tensioner by the fluid pump to thereby selectively vary the force applied to the camshaft-drive element. An internal combustion engine having such a camshaft-drive tensioner system and a method of selectively varying a force applied to the camshaft-drive element are also disclosed.

    Abstract: An internal combustion engine includes an engine assembly and an oil containment system attachable to the assembly. The oil containment system includes a cover component including an oil fill apparatus configured for conducting an oil to the internal combustion engine. The apparatus has a first end sealable with a cap, a second end spaced apart from the first end along a central longitudinal axis, and an annular wall concentric with and extending along the central longitudinal axis. The annular wall defines a first passage therethrough and a channel extending through the cover component along the central longitudinal axis. The oil containment system also includes a baffle component abutting the second end and defining a second passage therethrough such that the second passage is spaced apart from the channel.
