Abstract: A valve actuation system is disclosed for an engine. The valve actuation system may have a variable valve actuator that is configured to engage a rocker arm and hold the valve at an open position regardless of motion of a cam lobe. The variable valve actuator may have a housing forming a chamber, a plunger disposed in the chamber, a control valve movable to control a flow of fluid into the chamber, and a relief valve configured to automatically open and release fluid from the housing when a pressure inside the chamber is below a predetermined pressure. The valve actuation system may further have a controller configured to cycle the control valve prior to start-up of the engine and to selectively move the control valve after start-up.

Abstract: A fuel injector includes an injector body, and a stack within the injector body, and having a nozzle supply passage therein. The stack includes a solenoid assembly having a solenoid housing piece with a fuel bore formed therein that includes a segment of the nozzle supply passage. The solenoid housing piece includes a solenoid housing material in a base state, and a solenoid housing material in a residual compressive stressed state, with the fuel bore being formed by the solenoid housing material in the residual compressive stressed state. Residual stresses may be imparted by ballizing, nitriding, carburizing, autofrettage, or still another technique.
