摘要： In a motorcycle power unit, a crank shaft (56) and a clutch shaft (57) disposed on the right side (in the figure) from a body center (127) and a cylinder head (129H) is disposed on the left side from the body center (127). Since the crank shaft, the clutch shaft and a transmission shaft are disposed on one of right and left sides with respect to the body center and the cylinder is disposed on the other side with respect to the body center, it becomes possible to make a favorable lateral balance of the power unit.

摘要： An engine cooling structure for a water cooled engine includes water pump and a thermostat. The water pump pumps coolant to a water jacket of the engine. The water pump and thermostat are provided on a cover member installed on an outside of a crankcase of the engine, and a coolant passage, which communicates with the water jacket through the water pump from the thermostat, is integrally formed in the cover member, so as to obtain arrangement of the cooling structure that is efficient in terms of space. The engine cooling structure increases the degree of freedom of layout around a cylinder head by keeping the projection amount on a side of the cylinder head small, simplifies the piping construction, and reduces the number of assembly steps.

摘要： A motorcycle (1) is disclosed wherein a crank shaft (56) is disposed in a lower portion of a power unit case (55), a clutch shaft (57) is disposed in parallel to and higher than the crank shaft (56), and a transmission shaft (58) and an electric motor shaft (59) are disposed in such a manner as to extend from one end of the clutch shaft (57) in a longitudinal (fore and aft) direction of the vehicular body. That is, the clutch shaft (57), transmission shaft (58), and electric motor shaft (59) are disposed in series and also in parallel to and higher than the crank shaft (56). Since the transmission shaft (58) and the electric motor shaft (59) are disposed in series in the longitudinal direction of a vehicular body, the direction of a force applied to the power unit case (55) becomes simple. This makes the designing of the power unit case easy.

摘要： To provide a compact water-cooled four cycle engine suitable for a hybrid type power unit. The tension of a belt is increased by loosening bolts, turning an eccentric tube fitting, and moving a common pulley. After the tension of the belt is thus adjusted, the bolts are fastened. A water pump, which is supported by a shaft portion fitted in a guide groove and by the two bolts, are not moved except for the step of adjusting the tension of the belt 122. Since the tensioner serves as the pump pulley, it is possible to reduce the number of pulleys and hence to simplify the layout of the pulleys and reduce the number of parts. In accordance with another aspect of the present invention, a thermostat is mounted in a water jacket near an intake port of a cylinder head and is covered with an intake manifold. It is therefore unnecessary to provide a case and a lid for mounting the thermostat.

摘要： To provide a power unit less affected by the length of the cylinder of an engine. A cam shaft drive mechanism is composed of a cam shaft drive pulley, a belt, a pair of cam shaft pulleys, and a tensioner disposed on the front surface of a power unit. Since the cylinder is disposed in the width direction of the vehicular body with its cylinder axis substantially in the horizontal direction (for example, a tilt angle .alpha. with respect to the ground is set at +10), the center of gravity of the vehicle is lowered and also the cylinder length can be set within the vehicular width. This increases the degree of design of the vehicle.
