摘要： In a cooling system structure for a vehicular water-cooled internal combustion engine with a cylinder section and a cylinder body and a cylinder head. The cooling system structure having water jackets formed in the cylinder body and the cylinder head, respectively, with a radiator disposed forwardly of the engine main unit. A water pump performs forced circulation of coolant through the radiator and the water jackets, to permit routing of pipes with enhanced appearance. Water jackets are formed, respectively, in a cylinder body and a cylinder head such that coolant flows through the cylinder body and the cylinder head independently of each other. A thermostat is mounted on a front wall surface of a cylinder section and is capable of selecting a condition in which the water jackets directly communicate with each other or a condition in which the water jackets communicate with each other via a radiator.

摘要： An oil passage of an internal combustion engine including a crankcase, a cylinder block integrally connected to the crankcase, a piston operatively mounted within the cylinder block, a piston jet for providing oil to the piston within the cylinder block and a breather device integrally formed on the cylinder block wherein the breather device is in communication with the inside of the crankcase. An elevation of temperature of the oil which flows in an oil supply path is prevented thus allowing oil in the oil supply path to maintain a low temperature wherein the oil in the supply path is supplied to a piston jet formed on the internal combustion engine. An oil supply path through which oil is supplied to the piston jet is integrally formed on a wall body exposed to ambient air on a peripheral wall which forms the breather device.

摘要： An exhaust emission control device for an internal combustion engine including multiple reed valve chambers which are provided to cylinder head portions of a multi-cylinder engine. The reed valve chambers are formed by covering recessed portions in the cylinder head portion with reed valve covers. Upstream sides of the reed valve chambers communicate with the atmosphere via a secondary air supply pipe. Downstream sides of the reed valve chambers communicate with exhaust ports via communication passages provided to the cylinder head portion. The reed valves are interposed between the upstream sides and the downstream sides of the reed valve chambers, and are opened by exhaust pulsation pressure. In the cylinder head portion, the multiple reed valve chambers are disposed with spaces therebetween. The reed valve covers communicate individually with the secondary air supply pipe, and the reed valve covers are connected in series by the secondary air supply pipe.

摘要： In an electric motor cooling structure for cooling an electric motor provided in a power unit by jetting an oil to the electric motor, an oil passage for passing the oil therethrough is formed between a cover member covering the electric motor from outside and a lid member fitted to the cover member. The cover member is formed with a plurality of jet holes as through-holes communicating with the oil passage, and the plurality of jet holes are oriented in the same direction as an axial direction of the motor. The oil passage is formed in an annular shape as viewed in the axial direction of the electric motor. The cover member is formed with a second oil passage for supplying the oil to a rotary shaft of the electric motor. Such cooling structure efficiently cools the electric motor while suppressing processing cost with a simple oil passage structure.
