A FLANGE AND SEALING COLLAR ASSEMBLY which comprises a flange and a sealing collar, the sealing collar being mounted inside the flange, where the sealing collar has a front portion with a smaller diameter than the rear portion, two rings piston in the anterior portion and the flange has a communication channel that interconnects the middle portion between the piston rings of the sealing collar with the exhaust manifold coupled to the turbocharged system, obtaining the advantage of through the positive pressure coming from the exhaust manifold prevent the return of lubricating oil to the compressor of the turbocharged system.

A bearing supporting an end of a layshaft in an internal combustion engine is lubricated by injection of oil through a flange that mounts the layshaft on the engine. A pressure responsive flow control valve controls delivery of oil through the flange to the bearing. A backflow prevention adapter prevents back flow of oil to the engine's oil pump.

Cover (25) is mounted on wall surface (12) on the front side of cylinder block (10). Sub gallery (26) through which engine oil flows is formed between cover (25) and wall surface (12). Chain tensioner (17) is mounted on cover (25), and the engine oil in sub gallery (26) is supplied to chain tensioner (17) through oil supply port (31) formed through cover (25).

An apparatus includes an exhaust gas purification device configured to be coupled to a cylinder head of an engine via a bracket, the exhaust gas purification device defined by a housing including a body portion, a first end portion, and a second end portion, the body portion interposed between the first end portion and the second end portion, the first end portion configured to be coupled to the bracket.

A rocker arm assembly for translating force between an intermediate member in communication with a camshaft of an internal combustion engine and a valve supported in a cylinder head of the engine. The rocker arm assembly includes a tube member and an arm. The tube member has first and second ends, a substantially cylindrical inner surface, and a tapered outer surface. The arm has a body extending between a pad for engaging the valve of the engine, and a socket for engaging the intermediate member of the engine. The body also has a tapered bore disposed between the pad and the socket. The tapered bore of the body of the arm cooperates with the tapered outer surface of the tube member so as to define a lock for constraining the arm to the tube member at a predetermined position between the first end and the second end.

A variable valve device includes a pair of cam housings separated from each other in a predetermined direction, a pair of rocker shafts supported by the pair of cam housings, a plurality of rocker arms supported by the pair of rocker shafts in a swingable manner, a switching mechanism that couples and separates intake arms, and an upper housing on the pair of cam housings. The upper housing is formed with a first injection hole for supplying lubrication oil to the switching mechanism and a second injection hole for supplying lubrication oil to the rocker arms. A passage length from a lubrication groove around a camshaft to the second injection hole is larger than a passage length from the lubrication groove to the first injection hole.

A fluid delivery system is provided including a reservoir including oil, a hydraulic pump in fluid communication with the reservoir, and a heat exchanger system. The heat exchanger system is in fluid communication with the hydraulic pump, a generator, and an engine gearbox. The hydraulic pump is configured to deliver the oil to the heat exchanger system. The heat exchanger system is configured to provide the oil according to first temperature criteria to the generator and provide the oil according to second temperature criteria to the engine gearbox.
