摘要： Oil feed and discharge lines (34) and (35) are respectively connected between an engine (15) and an external oil feed type engine-driven supercharger (I) so as to circulate a lubricating oil (0) between them. The lubricating oil (0) used in the engine (15) is fed through the oil feed line (34) to the supercharger (I) while the lubricating oil (0) used in the supercharger (I) is returned through the oil discharge line (34) to the engine (15). As a result, the lubricating oil and associated parts exclusively for the supercharger can be eliminated.

摘要： A mechanical supercharger of an internal combustion engine has a housing formed with inlet and outlet ports and a pair of spiral screws rotatably received in the housing for partially compressing air introduced in the mechanical supercharger and carrying it from the inlet port to the outlet port. The supercharger is disposed after a throttle valve in an intake system of the engine, and is provided with a relief port allowing compressed air to be relieved from the supercharger. The relief port is formed in the housing between the inlet and outlet ports where air is compressed to allow compressed air to be relieved. A relief valve is controlled to variably open according to engine operating conditions and relieve compressed air in the supercharger.

摘要： A metal gasket capable of preventing the occurrence of cracks in a stopper while employing a wave-shaped stopper, improving the contact pressure balance around the bead to enhance the engine performance, and improving the durability of the stopper. The metal gasket is constituted by a gasket component sheet having an opening formed to face a combustion chamber, and the gasket component sheet is provided with a combustion chamber bead surrounding the opening. An inner circumference side stopper lower than the height of the combustion chamber bead is formed along the combustion chamber bead in a portion between the combustion chamber bead and the opening such that at least a section of each wave where stress amplitude is large becomes thin, a thin portion and a thick portion are arranged alternately in each wave, and the hardness of the thin portion is higher than that of the thick portion.
