Abstract: A rocker arm cover providing diagnosis and repair access to the rocker arm while the engine is running. The rocker arm is also capable of protecting a rocker arm from contacting other components of the engine, reducing contamination, and inhibiting oil and fluids from dispersing. The casing includes a multiplicity of access holes positioned along the casing, and positioned for accessing the rocker arm. A plurality of removable caps and joining mechanisms cover the access holes. Upon removal of the caps and joining mechanisms, a listening device with a diaphragm may be utilized to listen for specific rattling sounds associated with a loose rocker arm, or other valve in the cam system.

Abstract: A method of manufacturing a valve for an internal combustion engine, comprises: (i) a primary step of forging a bulging portion at one end of a rod material to form a generally disk-shape valve head of the valve having a tapered periphery; (ii) an thickness adjustment step of machining an excessively thick portion of the valve head; and (iii) a secondary step of forging a peripheral region of the valve head to create radial slip deformations therein to form a valve face of the valve head. In the step of thickness adjustment, only the front end of the disk-shape valve head is machined without harming dense grain flow lines induced in the tapered face (16a) in the primary forging while advantageously saving the valve material and reducing thickness adjustment time. In the secondary forging, the hardness of the valve face is further enhanced.

Abstract: Disclosed is a vehicle control apparatus which can execute a start-up control for improving acceleration performance at the time of starting an internal combustion engine during the running of a hybrid vehicle. When a hybrid ECU determines that a predetermined time has not yet elapsed after termination of the start-up control of the engine, and that the hybrid vehicle is in a high speed, high load condition, but not in a warming-up state, the hybrid ECU sets a value Nupest2 larger than a value Nupest1, that is usually set as a maximum value Krmx of a rise rate of an engine rotational speed.

Abstract: An adjustable camshaft sprocket assembly includes a hub and a sprocket body secured to the hub. A stud-receiving opening is defined in one of the hub flange and the sprocket body, and a tool-receiving opening is defined in the other of the hub flange and the sprocket body. The tool-receiving opening is aligned with the stud-receiving opening and is adapted to receive a body portion of an adjustment tool, and the stud-receiving opening is adapted to receive an eccentric stud of the adjustment tool. Either the stud-receiving opening or the tool-receiving opening is elongated. Rotation of the adjustment tool when its body is located in the tool-receiving opening and its eccentric stud is located in the stud-receiving opening causes relative angular movement between the hub and the sprocket body.
