摘要： A valve operating mechanism for operating a single valve of a particular cylinder of an internal combustion engine includes a camshaft rotatable in synchronism with rotation of the internal combustion engine and having at least one cam, and a plurality of cam followers, one of which slidably engages the cam for selectively operating the valves according to a cam profile of the cam. The cam followers are selectively interconnected and disconnected to operate the valve differently in different speed ranges of the internal combustion engine. In different embodiments, the camshaft has an annular raised portion and low- and high-speed cams, or low-, medium-, and high-speed cams, or an annular raised portion and a cam, and the cam followers are held in sliding contact with these raised portion and cams. The valve is selectively kept inoperative by the raised portion and operated in low- and high-speed ranges by the low- and high-speed cams, or selectively operated in low-, medium-, and high-speed ranges by the low-, medium-, and high-speed cams, or selectively kept inoperative by the raised portion and operated in a high-speed range by the cam.

摘要： A valve operating mechanism for operating a plurality of valves of an internal combustion engine includes a camshaft rotatable in synchronism with rotation of the internal combustion engine and having an array of three cams including a high-speed cam positioned at one end of the array. Three cam followers are held in sliding contact with the cams, respectively, for operating the valves according to cam profiles of the cams. The cam followers are selectively interconnected and disconnected to operate the valves at different valve timings in different speed ranges of the internal combustion engine. The speed ranges include a high-speed range in which all of the valves are controlled by the cam profile of the high-speed cam. The three cams may include low- and medium-speed cams, or two identical or different low-speed cams, in addition to the high-speed cam. These cams may be differently arranged in the array, and the cam followers include those which slidably engage one or two of the cams for operating the valves. The valves are operated selectively in low- and high-speed ranges, or in low-, medium-, and high-speed ranges, with different combinations of the cams.

摘要： A power unit mounting structure in a motor vehicle includes a power unit comprising an engine having a crankshaft, a transmission coupled to the crankshaft of the engine, and a differential interposed between drive axles connected to a pair of laterally spaced front road wheels of the motor vehicle and the transmission. The power unit is mounted in a front portion of the motor vehicle with its center of gravity positioned rearwardly of the drive axles extending from the differential toward front road wheels serving as the drive road wheels. A steering gearbox extends parallel to the drive axles and is disposed forwardly of the drive axles.
