    摘要： A cylinder block of a multicylinder engine, having a cylinder main body in which multiple cylinder bores are provided in parallel in an axial direction of a crankshaft, and a crankcase having plural journal walls. The crankcase is integrally provided with the cylinder main body, in which a communication hole extending in parallel to the axial line of the crankshaft is provided in the cylinder main body and the crankcase while at least a part of which is opened in the inner peripheral surface of the cylinder bore. This permits the cylinder block to be downsized, increases freedom of positional setting of the communication hole, and reduces ventilation resistance of air flow through the communication hole. A cut-processed member is expanded further outward from a piston slide surface and is formed along a radial direction of cylinder bores, in inner surfaces of the cylinder bores in at least portions closer to a piston at an open edge of a communication hole.

    摘要： A supercharger lubricating structure for an internal combustion engine is provided that can supply oil to a supercharger through a short oil passage without use of external piping and downsize a lubricating oil pump. A supercharger lubricating structure for an internal combustion engine can be characterized by the following: A rotating shaft can be connected to a crankshaft via a joint. A connection pipe can be insertably passed through the crankshaft and the rotating shaft to allow an intra-crankshaft oil-feed passage and an intra-rotating-shaft oil-feed passage to communicate with each other. An eccentric shaft portion can be provided on the rotating shaft. A supercharger composed of an orbiting movable scroll and front and rear fixed scrolls can be provided on the eccentric shaft portion via needle bearings. The front and rear fixed scrolls can be provided with ball bearings and the needle bearing supporting the rotating shaft. Oil passages can be disposed to allow the intra-rotating-shaft oil-feed passage, the ball bearing, the needle bearing and the needle bearings to communicate with one another.

    摘要： A scroll compressor including a stationary scroll formed with a scroll wrap, an orbiting scroll formed with a scroll wrap, a rotating shaft for putting the orbiting scroll into an orbiting motion, a rotating bearing for rotatably supporting the rotating shaft on the stationary scroll, an orbiting scroll bearing provided at an eccentric shaft portion of the rotating shaft and operative to orbitably support a central portion of the orbiting scroll. A coupling transmits a torque of a driving shaft to the rotating shaft. The scroll compressor is compact based on the layout of a balancer. The orbiting scroll bearing is disposed at a central portion of the rotating shaft, and the coupling is provided with the balancer. The stationary scroll may be provided with ribs being formed therein with an oil passage for connection between a central oil passage formed in the rotating shaft and the exterior.

    摘要： A piston cooling structure for a multicylinder engine having oil jets for ejecting oil toward pistons. The oil jets are mounted in each of a plurality of journal walls except one journal wall. The piston cooling structure is able to supply oil to a cylinder head in a position closer to a central region along the axis of the crankshaft while avoiding a complex oil passage shape. An oil passage for guiding oil to a cylinder head is defined in the one of the journal walls without an oil jet, and this one journal wall is disposed between a pair of adjacent cylinder bores. Oil jets are mounted in each of the other journal walls. A crankshaft of the engine is rotatably supported by the journal walls.
