摘要： The invention provides an internal combustion engine equipped with a variable valve control system which switches the actions of an engine valve by sliding a rocker arm in the axial direction of the rocker arm shaft, while enabling the restriction on the sliding movement of the rocker arm to be removed in accordance with the timings of the actions of the rocker arms irrespective of the engine speed. The internal combustion engine includes an actuator that moves a rocker arm shaft in its axial direction, a trigger arm that engages with a rocker arm to prohibit the sliding movement of the rocker arm, and a trigger pin which is configured to be activated by an axial movement of the rocker arm shaft to bring the trigger arm into action, and to disengage the trigger arm from the rocker arm.

摘要： An internal combustion engine is equipped with a variable valve control system which is operable to selectively actuate an engine valve using one of two cams of a camshaft, by sliding a rocker arm in the axial direction of a rocker-arm shaft. The system is capable of restricting the axial-direction movement of the rocker arm within a predetermined range, using a simple structure without unduly increasing the number of component parts. Position-restriction portions are formed in a rocker arm, and abut on a trigger arm to restrict sliding movement of the rocker arm within a predetermined amount, when the trigger arm is disengaged from the rocker arm.

摘要： In an oil cooler, a heat exchange core is housed in a casing including a cylindrical sidewall part in a way that a cooling water passage is formed around a heat exchange core. The heat exchange core includes inlet-side and outlet-side oil passages, and enables oil to be delivered from the inlet-side oil passage to the outlet-side oil passage. Inlet and outlet pipes are connected to the sidewall part. The inlet pipe forms a cooling water inlet passage in communication with the cooling water passage. The outlet pipe forms a cooling water outlet passage in communication with the cooling water passage. Outward of the inlet-side oil passage, an outwardly swelling part is formed in the sidewall part of the casing. This arrangement avoids the oil cooler being constructed in a large size and avoids decreasing the heat exchange efficiency of the oil cooler, and also prevents cavitation and erosion from occurring due to the flow of cooling water in an area corresponding to the inlet-side oil passage.

摘要： A breather apparatus for an internal combustion engine which, when casting a cylinder head cover, can improve the fluidity of molten metal and promote gas-liquid separation through effective use of an entire breather chamber. A breather apparatus for an internal combustion engine has a cylinder head cover in which a breather chamber is formed. In the breather chamber, a number of ribs extend from a side wall included in a peripheral wall of the chamber obliquely relative to a direction in which blowby gas flows in through inflow ports. The ribs extend up to where they are continuous with respective fixing bosses. The ribs include projecting lower edge portions which are partly cut out, forming respective concave portions.

摘要： An internal combustion engine in a power unit includes an oil pump that rotates by a transmission mechanism with an endless chain, and a crankcase with an opening formed by protruding walls of side walls of the crankcase in an axial direction. A drive sprocket is fitted to a main shaft of a gear transmission and a driven sprocket is fitted to a shaft end of a drive shaft of an oil pump. When viewed sideways, the protruding walls and mating faces have overlapping parts that partially overlap the driven sprocket. On the other hand, all the shaft end and the remainder of the driven sprocket are exposed inside the opening when the cover is removed. The resulting configuration improves the working efficiency in fitting an oil pump into the crankcase without reducing the rigidity of the crankcase.

摘要： A cooling structure is a separate member from a structural portion of an engine. An oil injection pipe includes cooling oil injection holes for injecting cooling oil into cylinder bores and is mounted across an engine at a somewhat upper position with respect to a crank shaft and in parallel with the crank shaft. Both ends of the oil injection pipe are fixed through mounting members to right and left side walls of the engine, whereby the pipe is mounted. Two left and right pipe portions are joined together at a central position between the two to constitute the oil injection pipe as a single pipe. At the connection in the central position, the oil injection pipe is connected to an oil supply path. Oil supplied through the oil supply path flows into the left and right pipe portions and is injected from the injection holes into the cylinder bores.
