Abstract: A rocker housing is configured to enclose a rocker shaft and rocker arms connected to push rods that protrude from a cylinder head of an internal combustion engine. The rocker housing comprises a sidewall configured to enclose the rocker shaft and a top wall extending laterally from an upper portion of the sidewall so as to extend over the rocker arms. The rocker housing further comprises an aperture configured to accommodate a fuel injector or a fuel supply pipe for supplying fuel to a fuel injector of the internal combustion engine. The rocker housing further comprises a fuel return channel extending within at least a part of the sidewall. The fuel return channel comprises an inlet at the interior surface of the sidewall configured to receive excess fuel from the injector; an outlet at an exterior surface of the sidewall configured to output the excess fuel, wherein the outlet is laterally offset from the inlet; and an interior passage extending between the inlet and the outlet.

Abstract: Multi-plate brake or clutch includes a carrier, a fluid dispensing device and plurality of friction plates located around the carrier and the fluid dispensing device. The carrier includes a carrier body, a plurality of external splines located around a rim of the carrier body extending outwardly from the rim, and a passageway that extends through the carrier body to a passageway outlet. The fluid dispensing device includes a body defining a reservoir with an opening in fluid communication with the passageway outlet to allow fluid to be dispensed when a volume of fluid in the reservoir exceeds a predetermined volume.

Abstract: A method of remanufacturing a cylinder head comprises the steps of removing material from the cylinder head around at least a portion of a crack in the cylinder head to form a slot, and applying a compound material using direct laser deposition to fill the slot. The direct laser deposition includes performing a pre-scanning operation at a first laser power and a first scan speed, and depositing the compound material at a second laser power and a second scan speed. The second laser power and the second scan speed may be respectively equal to or different from the first laser power and first scan speed. The first laser power and the second laser power are less than or equal to 700 W. The first scan speed and second scan speed are less than or equal to 700 mm/minute.

Abstract: This disclosure relates to a process for at least one of engaging and disengaging splined members in a vehicle system. The process includes applying an axial reciprocating motion to one splined member and applying an oscillatory motion to another splined member such as a gear. This enables the splined member to be moved at least one of into and out of engagement with the gear.
