Abstract: A method for operating an internal combustion engine, wherein a valve of a cylinder is opened by a cam of a camshaft within a duty cycle of the engine, and a specified quantity of fuel is supplied to the cylinder. A dimension of the cam and/or a position of the cam on the camshaft is measured after the cam and/or the camshaft has been produced. The dimension, position, and/or a characteristic variable ascertained therefrom is stored, and the quantity of the fuel to be fed within the duty cycle is determined dependent on the stored dimension, position, and/or characteristic variable calculated therefrom. An internal combustion engine is also described for carrying out the method according to the invention.

Abstract: A tappet clearance setting apparatus includes a screwdriver, a pneumatic portion, and a controller. The screwdriver engages the tappet screw and the pneumatic portion provides a monitored and air flow through an engine cylinder. The controller directs the screwdriver to tighten the tappet until the air flow through the cylinder is indicative of a valve opening. The controller then directs the screwdriver to reverse directions until the sensed air flow indicates that the valve has closed, which further indicates that the tappet screw is in a reference position. From the reference position, the controller directs the screwdriver to loosen the tappet a predetermined amount to establish the desired tappet clearance.

Abstract: A partial assembly process for a vane-type cam phaser. A pulley/sprocket is loaded onto a first camshaft-shaped fixture with a cam nose extending beyond the length of an actual cam nose such that a phaser rotor containing a locking bolt, when mounted onto the cam nose, is displaced axially from the pulley/sprocket by an amount sufficient to set the axial engagement of the bolt upon final assembly. A stator is loaded onto the pulley/sprocket and is rotated clockwise until it contacts the rotor, thereby removing all rotational and radial lash from the system. One or more axial holes are bored through the pulley/sprocket and stator and a locking pin such as a roll pin is inserted to permanently pin the stator to the pulley/sprocket. Finally, the partially-assembled phaser is removed from the cam-like fixture, the rotor is fully seated against the pulley/sprocket, the locking bolt is withdrawn from the pulley/sprocket, the rotor is rotated to an intermediate position, and the phaser cover is added to the assembly.

Abstract: A method for automatically setting valve clearances in internal combustion engines (also known as “tappet setting” or “valve lash setting”) comprises a series of steps in which a rocker arm is set to a zero position that is recorded as a reference datum and an adjustment screw is then operated to set the rocker arm to a first reference position. The adjustment screw is then rotated through a predetermined angle so that the rocker arm is moved to a second reference position. The difference between the first and second reference positions and the predetermined angle are used to determine a coefficient relating the angular movement of the adjustment screw to linear movement of the rocker arm. The coefficient is then used to calculate the angular rotation of the adjustment screw required to set a predetermined valve clearance relative to the zero position. The initial adjustment of the rocker arm position serves to neutralize backlash in the valve drive train prior to setting the valve clearance. The method and associated apparatus may also be used to set the clearance between a rocker arm and other rocker arm actuated engine components.

Abstract: A continuously variable valve duration (CVVD) system includes a controller configured to determine whether a learning value existing in the CVVD system is required to be verified during one of a hardware abnormality, a learning value abnormality, and a motor voltage abnormality. In particular, the controller performs a learning value verification control using a rotation detection value and switches from a learning value verification control to a re-learning control when re-learning is required.
