Abstract: A lash compensator for a valve train component of an internal combustion engine is provided that includes an end-cap arranged within a reverse-spring control valve assembly of an axially moveable piston. The piston has a first reservoir and an inner radial wall configured with a through-aperture. The reverse-spring control valve assembly has a control valve housing, a bias spring, an end-cap, and a closing body. The end-cap is configured with a cupped end; an inner side of the cupped end receives a second lower end of the bias spring, and an outer side of the cupped end engages an upper portion of the closing body. The end-cap minimizes or eliminates the variation in flow resistance caused by a variation in end-coil geometry of the second lower end of the bias spring.

Abstract: An electric boost pump oiler system is set forth to assist the engine driven oil pump of a motorcycle engine, to prevent the decrease of oil pressure at a preset value of 10 psi automatically during above normal oil operation temperatures at engine idle speeds. Additionally before engine start, the boost pump oiler will automatically deliver oil through the engine for 10 seconds to prevent internal mechanism dry starts and prime the hydraulic lifters. Additionally in the event of an engine driven oil pump failure, the boost pump oiler will automatically deliver oil pressure through the engine's internal mechanisms to prevent engine seizure. Additionally to remove oil from the oil tank, a drain hose will quick connect to the output port of the boost pump oiler delivering oil to a collection container. Additionally the oiler mounts in a saddle bag for concealment with quick connect/disconnect hoses and quick connect/disconnect electrical fittings for saddle bag removal.

Abstract: A method for detecting a low-lift or zero-lift failure mode in a variable valve activation system of an internal combustion engine includes the steps of positioning a piezo-electric element that acts as a radio frequency transmitter relative to a lost motion spring of a two-mode variable valve activation lost motion device, subjecting the piezo-electric element to a compression load when a load from displacement of a lobe of a camshaft acts on the lost motion spring, broadcasting a radio frequency signal each time the piezo-electric element is subjected to the compression load, and evaluating the presence or absence of the broadcasted radio frequency signal in relation to an expected presence or absence of the radio frequency signal. The direct measurement of the mode of each two-mode device is both more reliable and more efficient in the use of engine controller resources compared to currently existing diagnostic methods.

Abstract: The invention concerns a mounting and anti-rotation device (mounting aid) (1) for roller tappets of a valve train of an internal combustion engine in which gas exchange valves are activated by roller tappets. The roller tappets comprising a substantially cylindrical tappet body are retained in receptions (7, 8) of the mounting aid (1) that is made of plastic. With the help of opposing parallel anti-rotation surfaces that are arranged symmetrically to the longitudinal axis of the roller tappet and are disposed on the end of the tappet body that is oriented away from a roller, the roller tappets are guided secured against rotation in the mounting aid during the operation of the internal combustion engine. This is achieved by the fact that the inner profile of the receptions (7, 8) is matched to the outer profile of the roller tappets. To avoid mixing up the switchable with the non-switchable roller tappets during assembly, the distances between the anti-rotation surfaces on the different roller tappets, and thus also the inner contours of the corresponding receptions (7, 8) are chosen so as to differ markedly from each other. To achieve the correct orientation of the switchable roller tappets, for example, relative to an oil gallery, the anti-rotation surfaces of the switchable roller tappets and the corresponding receptions (8) of the mounting aid (1) are arranged asymmetrically to the longitudinal axis of the tappet body and comprise a groove (32) or a rib (35), respectively.
