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.

摘要： A valve operating mechanism for an internal combustion engine wherein a plurality of rotatable cams have different cam profiles for operating an intake or exhaust valve differently in high and low speed ranges of the engine. A plurality of rocker arms are selectively connected or disconnected for transmitting the appropriate cam lift to the valve depending on the engine speed range. The cam profiles have dampening areas at the start of opening and the finish of closing of the valve. The dampening areas of the high speed cam have a smaller rate of change than the dampening areas of the low speed cam to minimize the possibility of engagement by a rocker arm with a cam for one speed while the engine is operating at another speed by another cam and rocker arm.

摘要： An intake system for an internal combustion engine includes first and second intake valve bores provided to face a combustion chamber and to be independently opened and closed by first and second intake valves, and first and second intake ports which are connected to the corresponding intake valve bores with a partition wall interposed therebetween and which communicate with a common intake passage. In a particular operation range of the engine, an imbalance is produced in the concentration of the air-fuel mixture flowing through the first and second intake valve bores into the combustion chamber on the basis of a difference between the amounts of fresh air flowing into the first and second intake ports. The intake system further includes a communication hole provided in the partition wall for putting the first and second intake ports into communication with each other. This provides for improvements in the lean combustibility and in the nature of the exhaust gas.

摘要： A valve operating mechanism for operating a plurality of valves 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. At least one of a plurality of cam followers 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 valves in different speed ranges of the internal combustion engine, the speed ranges including a range in which all of the valves remain inoperative. The camshaft has one or two annular raised portions in addition to the cam, and the cam followers include one or two cam followers which slidably engage the raised portion or portions. The valves remain inoperative by the annular portion or portions and are operated in a high-speed range by the cam, or selectively in low- and high-speed ranges by low- and high-speed ranges.

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.
