Abstract: A tensioner device for a belt or chain defines a housing defining a bore with a plunger disposed in the bore. A spring is engaged with the plunger for biasing the plunger in an outward direction. The housing further includes an oil chamber connected to an oil passage in communication with the oil chamber for delivering pressurized oil to the oil chamber, wherein when the oil chamber is pressurized the pressurized oil applies a counter force opposing a force of the spring.

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: 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.
