摘要： An overhead-valve internal combustion engine with a breather chamber arranged below a camshaft housing chamber for housing the camshaft and formed between a cylinder head and a cylinder block. A driving force transmission chamber is formed between a cylinder and a crankcase. Thus, the discharge of oil from the breather chamber is performed smoothly so as to enhance the vapor-liquid separation performance. A breather inlet passage has an upper end thereof in communication with an inside of a camshaft housing chamber and a lower end thereof in communication with a breather chamber at a position corresponding to a mating face between a cylinder block and a crankcase is formed in the cylinder block such that the breather inlet passage extends vertically. An oil discharge hole is in communication with a lower portion of the inside of the breather chamber and is formed in the crankcase.

摘要： An oil separating chamber for separating oil contained in blow-by gas is arranged outside a transmission member passage connecting a crank shaft with a cam shaft of a valve system and at an abutting surface between a cylinder block and a cylinder head. Partition walls perpendicular to the abutting surface for dividing the oil separating chamber into a plurality of small subchambers are alternatively arranged at the cylinder block and the cylinder head to form a labyrinth structure. The small subchamber at one end of the plurality of small subchambers is provided with a blow-by gas intake passage communicated with the transmission member passage. The small subchamber at the other end is provided with a blow-by gas exhaust passage for returning blow-by gas to an air cleaner. Each of the small subchambers not provided with the blow-by gas intake passage is provided with an oil return passage communicating with the transmission member passage. This arrangement and construction of an oil separator structure for separating oil contained in blow-by gas of an internal combustion engine reduces the number of component parts and the number of assembling steps.

摘要： A diesel engine crankcase ventilation filter is provided by a flat low profile filter housing extending in a horizontal plane and having an upper planar horizontal surface, a lower planar horizontal surface, and side surfaces extending between the upper and lower surfaces. A planar horizontal flat panel filter element extends parallel to the upper and lower surfaces. The housing has an upper plenum between the flat panel filter element and the upper surface, and a lower plenum between the flat panel filter element and the lower surface, an inlet receiving oil and air from the diesel engine and supplying same along an inlet path to the upper plenum to flow downwardly through the flat panel filter element to the lower plenum, a first outlet outputting air along a first outlet path from the lower plenum, and a second outlet outputting oil along a second outlet path from the lower plenum.

摘要： A device to reduce corrosion which occurs in an internal combustion engine during long periods of non-use. Inactivity allows atmospheric moisture to collect on internal engine surfaces producing rust, and in the engine oil producing slug. This invention provides a means of reducing the presence of this moisture by pressurizing the internal engine areas with low humidity air.

摘要： Engine-driven portable tools are widely used for different kinds of work where the surrounding conditions are very different. Large variations in temperature can cause problems for the engine, especially during low temperatures that occur during winter. The present invention reduces these problems in a simple and effective way by guiding heated air from the area adjacent to the muffler through a channel placed outside the casing to the air inlet for the engine. The cold air sucked into the engine is mixed with the heated air from the channel so that the temperature of the air mixture is increased.

摘要： A centrifuge for cleaning the lubricating oil of an internal combustion engine, which simultaneously cleans the crankcase gases in which the separation result is improved by introducing crankcase gases (dashed arrows) directly, without any shielding baffles, into the oil mist generated by the drive nozzles in the centrifuge housing in order to produce a scrubbing effect, so that the crankcase gases are precleaned. For additional cleaning, guide vanes mounted on the rotor swirl the crankcase gas so that further residues are deposited along the walls of the housing, thereby making further measures to clean the crankcase gases unnecessary, with the result that the apparatus highly economical since it saves both material costs and maintenance costs.
