摘要： A quantitative one-way oil gas lubricant system and a method for a 4-stroke engine, including a preceding stage quantitative oil intake orifice that is connected to a lubricant case on a wall of a crankcase of the 4-stroke engine, and a final stage quantitative airflow orifice disposed at a cylinder cover of the 4-stroke engine, are provided. A diameter of the preceding stage quantitative oil intake orifice D1 and a diameter of the final stage quantitative airflow orifice satisfy an equation: D1/D3=0.8-1.5, wherein a one-way connected oil gas lubricant channel is disposed between the preceding stage quantitative oil intake orifice and the final stage quantitative airflow orifice. A lubricant oil sucked from the preceding quantitative oil intake orifice by the crankcase flows along the oil gas lubricant channel and lubricates the engine parts that the channel passes through in turns. Finally, a minute quantity of waste oil gas that flows out from the final stage quantitative airflow orifice is introduced into a cylinder of the 4-stroke engine and is to be burned completely. The supply quantity of the lubricant oil may be controlled, and no extra lubricant oil gas may flow out from the final stage quantitative airflow orifice, therefore, the quantitative and one-way lubricating is realized.

摘要： In an oil filter attaching structure for a vehicle-mounted internal combustion engine, an oil filter of the engine is installed in a filter case integrally formed with a crankcase cover of a crankcase. The crankcase cover is mounted on a side surface of the crankcase so as to cover an end of a crankshaft supported by the crankcase to extend in vehicle widthwise directions. An internal combustion engine accessory and a transmission clutch device are disposed inside of the crankcase cover in respective positions forward and rearward of the crankshaft. The oil filter and an oil supply port are disposed inside of the crankcase cover in respective positions upward and downward of the crankshaft. The oil filter attaching structure efficiently utilizes the space for making itself smaller in size and for better maintainability.

摘要： A primary housing for a motorcycle engine includes an inner housing that defines internal coupling apertures, transmission coupling apertures, and external coupling apertures. Internal fasteners extend through the internal coupling apertures and the transmission coupling apertures to couple the inner housing to the crankcase and the transmission. An outer housing defines coupling apertures that align with the external coupling apertures and fasteners extend through the coupling apertures, through the external coupling apertures, and into the engine crankcase to couple the inner and outer housings to the crankcase. A resonant damping device is rigidly or moveably coupled to an anti-node region of the outer housing to reduce noise emissions from the outer housing during engine operation.

摘要： An engine block 10 is disclosed having machined front and rear faces. Each of the front and rear faces is capable of receiving and sealing against a housing (20,40) enclosing a gear train for coupling the engine crankshaft to a camshaft of the engine. The front face is additionally capable of directly receiving and sealing against an engine front cover while the rear face is additionally capable of directly receiving and sealing against a flywheel housing. In this way, the same engine block may be selectively assembled into an engine having a front mounted or a rear mounted camshaft gear train.

摘要： An electric variable valve timing apparatus includes a sprocket unit and an electric motor. The electric motor is fixed to a chain cover with bolts. The chain cover includes plural bosses each having an internal thread to which one of the bolts is threaded. The bosses extend from the chain cover toward the sprocket unit to positions at which the bosses face an outer periphery of the sprocket unit in a radial direction. The bosses are arranged such that, when the sprocket unit moves downward from an attaching position, at which the sprocket unit is attached to the camshaft, at least two bosses are engaged with the sprocket unit to restrict downward movement of the sprocket unit, and that the sprocket unit is allowed to move between a location outside of a space covered by the chain cover and the attaching position.
