Publication number: 20160222841Abstract: A lost motion engine valve actuation system and method of actuating an engine valve are disclosed. The system may comprise a valve train element, a pivoting lever, a control piston, and a hydraulic circuit. The pivoting lever may include a first end for contacting the control piston, a second end for transmitting motion to a valve stem and a means for contacting a valve train element. The amount of lost motion provided by the system may be selected by varying the position of the control piston relative to the pivoting lever. Variation of the control piston position may be carried out by placing the control piston in hydraulic communication with a control trigger valve and one or more accumulators. Actuation of the trigger valve releases hydraulic fluid allowing for adjustment of the control piston position. Means for limiting valve seating velocity, filling the hydraulic circuit upon engine start up, and mechanically locking the control piston/lever for a fixed level of valve actuation are also disclosed.Type: ApplicationFiled: January 8, 2016Publication date: August 4, 2016Inventors: Joesph M. Vorih, Jeffrey Mossberg, Richard Vanderpoel, Steven Ernest, Guy Paterson, John A. Schwoerer, Edward T. Leitkowski, Andrew Brzoska, Gheorghe Cosma
