Abstract: An engine valve actuation system is provided. The engine valve actuation system includes an intake valve that is moveable between a first position to prevent a flow of fluid and a second position to allow a flow of fluid. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator is configured to selectively prevent the intake valve from moving to the first position. A source of fluid is in fluid communication with the fluid actuator. A directional control valve is configured to control a flow of fluid between the source of fluid and the fluid actuator. A check valve is disposed between the directional control valve and the source of fluid, only allowing fluid flow from the fluid source to the directional control valve. A bleed orifice may be disposed between the directional control valve and the source of fluid, in parallel with the check valve.

Abstract: A clamping assembly for clamping a fuel injector into a fuel injector bore located in cylinder head of an engine includes a housing having a housing opening, connectors coupling the housing to the cylinder head, and a compression spring. The compression spring is located in the housing opening, operably coupled to a top of the fuel injector, and axially aligned with a longitudinal axis of the fuel injector.

Abstract: Past applications have found that a joint becomes damaged due to the high loading and vibration loads in which it encounters during operation. The counterbored joint utilizes the flexible shim that is larger than the body receiving bore. A undercut is machined into the body receiving bore which allows for the flexible shim to be placed within the body receiving bore between the first and second step surfaces. The first step surface is parallel to the second step surface which distributes stresses uniformly and helps in sealing. The principal use is for a cylinder liner joint, however any joint that is highly loaded or encounters vibrational loads will benefit from this invention. For example, a hydraulic joint that utilizes a piston in operation may be remanufactured with this invention.
