Abstract: An internal combustion engine is provided with a DOHC-type valve train in a cylinder head. The valve train includes an intake side camshaft with an intake side driven gear, and an exhaust side camshaft with an exhaust side driven gear. The cylinder head supports therein a spindle with an idle gear with an idle chain sprocket fixed thereto. The idle gear is in meshing engagement with both the intake and exhaust side driven gears. Rotary power of a crankshaft is transmitted via a cam chain to the idle gear to rotate both the intake and exhaust side camshafts. These camshafts are supported by bearings of a bearing wall and a camshaft holder. These bearings and camshaft holder are located, for compact arrangement, at a position axially coinciding or overlapping with the idle chain sprocket.

Abstract: A multiple variable valve lift apparatus includes a camshaft. At least two cam portions are disposed on an exterior circumference of the camshaft and including a high cam and a normal cam. A cylinder deactivation device is configured to perform a lever motion by one of the high cam or the normal cam and to be operated by hydraulic pressure. At least two lift operating portions are disposed on the exterior circumference of the camshaft and moving the cam portions in an axial direction of the camshaft. An operation control portion selectively moves the operating portions in the axial direction of the camshaft. A guide rail is formed in a groove of an exterior circumference of the lift operating portions into which a pin is inserted. The guide rail guides the pin according to rotation of the camshaft and the operating portions.

Abstract: The variable lift valve train includes a spring-loaded valve that is in mechanical connection with a lever bar. The lever bar is attached to a stroke limiter. The lever bar extends across the spring-loaded valve and the stroke limiter. The lever bar is positioned under a first cam. The angle of the first cam adjusts the angular orientation of the lever bar with respect to the stroke limiter as well as the spring-loaded valve. The stroke limiter is biased via a stroke spring. Moreover, the stroke limiter extends downwardly, and optionally engages against a stroke limiter cam. The stroke limiter cam is optionally able to influence the stroke limiter, and is a secondary influence when compared to the angular orientation of the lever bar. In use, the variable lift valve train is able to adjust the timing and lift of the spring-loaded valve of the engine.

Abstract: A method for producing a camshaft module and a camshaft module are provided. The camshaft module includes a camshaft and a bearing frame having bearing devices with cut-outs. The camshaft includes a shaft and cams having cut-outs. The shaft has at least two different outside diameters. At least some of the cams and/or some of the bearing devices have cut-outs of differing diameters. The bearing frame is supported during shaft insertion to be movable along a movement axis during production of the camshaft module and to be substantially rigid along an insertion direction of the shaft. The shaft is inserted into the bearing frame in the insertion direction in such a way that interference fit is obtained in each case at least between the shaft and at least some of the cams. A predefined target distance between two elements such as a gear located outside of the bearing frame and a cam or bearing device located inside of the bearing frame adjacent to the element outside of the bearing frame may be obtained by partially inserting the shaft, determining a distance between the two elements, and applying an insertion force to the shaft based on the determined distance to advance the shaft to result in setting the distance between the two elements to the target distance.
