摘要： An arrangement and structure for an oil pan system to permit mounting a vertical in-line engine in a vehicle in a horizontal or nearly horizontal attitude includes a cylinder block of the engine having an opening on the side wall thereof, a cover attached to the cylinder block where an ordinary oil pan is usually mounted, an adapter plate fastened to the lower side wall of the cylinder block and bottom of the cover, and an oil pan attached to the lower surface of the adapter plate. The adapter plate allows the oil pan to extend and always remain below the cylinder block, so that the return paths from the lubricated portions of the engine to the oil pan are shortened.

摘要： An exhaust gas purifying apparatus for use in connection with an internal combustion engine, especially for an automobile. The apparatus includes a fluid flow changeover valve having an outlet connected to the intake system of the engine, an exhaust gas inlet connected to the exhaust system and an air inlet connected to a source of pressurized air, for example, an air pump driven by the engine. When rotation of the engine is slow and consequently the output pressure of the air source is low, supply of the air to the intake system is stopped but exhaust gas is supplied thereto, whereby generation of nitrogen oxides (NOx) is reduced. In response to increase in the engine speed, air and exhaust gas are both supplied to the intake system until the output pressure of the air source increases to a predetermined value, whereby uniform combustion of fuel-air mixture in cylinders is maintained. When the output pressure of the air source exceeds the predetermined value, supply of exhuast gas to the intake system is stopped but only air is supplied thereto, causing dilution of fuel-air mixture provided through the carburetor, whereby fuel consumption is decreased and overheating of the exhaust gas purifying apparatus is prevented.

摘要： An internal combustion engine having its cylinders tilted at an angle of less an than 90 degrees relative to a vertical axis is provided with a oil drain mechanism for drainign excess oil that collects when the engine stops. For this purpose, an oil drain hole, which communicates with an interior of the piston body to drain the lubricating oil, is formed in the inner wall of an oil ring groove in such a way as to be located below the center line of the piston body. Both ends of the oil drain hole are set lower than the lowest portion of a piston head. Therefore, it is possible to prevent lubricating oil from entering the combustion chamber when the engine stops, without providing a whirl-stop on piston rings.

摘要： Disclosed is a secondary air supplying device of an internal combustion engine having an exhaust passage provided with a catalyzer for purifying exhaust gas. The device includes a first air injection port provided in the exhaust passage at the upstream side of an exhaust manifold and a second air injection port provided in the exhaust passage at the upstream side of the catalyzer. Under the engine warming operating condition only when the engine speed is abruptly accelerated, or during a predetermined time interval after the engine is warmed, is secondary air injected into the exhaust passage from the second air injection port. When the engine is in the other operating conditions, secondary air is injected into the exhaust passage from the first air injection port.
