摘要： To provide a multi-cylinder engine in which a plurality of cylinder bore rows, each including a plurality of cylinder bores disposed in parallel, are disposed in such a manner as to be perpendicular to a crank shaft disposed substantially in the horizontal direction. A plurality of cylinder heads, each forming combustion chambers between pistons slidably fitted in the cylinder bores and the cylinder head, are connected to cylinder blocks corresponding to the cylinder bore rows. Furthermore, a plurality of intake passages and a plurality of exhaust passages respectively in communication with the combustion chambers are provided in the cylinder heads, wherein the structure of an intake system and an exhaust system can be simplified. Intake passages and exhaust passages are provided in the a cylinder head corresponding to a cylinder bore row in such a manner that a relative positional relationship between the intake passages and the exhaust passages in the axial direction of the crank shaft is nearly equal to that between the intake passages and the exhaust passages in the axial direction of the crank shaft.

摘要： A bearing metal positioning structure in a split connecting rod with lowered production cost and improved accuracy in positioning the bearing metal. The bearing metal positioning structure includes a pair of bearing metal halves, each of which is formed into a circular arc shape traversing 180 degrees. The pair of bearing metal halves have flat mating planes which abut one another to form a cylindrical bearing metal. A pair of projections are disposed on each of the mating planes at both axial ends so as to project radially outwardly therefrom. Locking grooves to be engaged with the pairs of projections, and additional locking grooves, are integrally die-formed simultaneously with the production of a die-formed body of the split connecting rod.

摘要： To deem a dedicated oil passage unnecessary and therefore make an engine equipped with a plurality of cylinder bores with substantially horizontal axes and provided with transmission mechanisms between a camshaft and crankshaft within a valve chamber more lightweight and compact while returning oil for a valve chamber to a crank chamber. Transmission mechanisms include endless chains wrapped around drive sprockets fixed to one end of a crankshaft and driven sprockets fixed to one end of camshafts. The transmission mechanisms are housed in transmission chambers in such a manner that ends of the transmission mechanisms are made to communicate with the valve chambers and the other ends of the transmission mechanisms are made to face one end in the axial direction of the crankshaft. A return hole causing the lower part of the other end of the transmission chambers to communicate with the crank chamber is provided at the crankcases.

摘要： A multi-cylinder engine in which a transmission mechanism is provided between a cam shaft linked with intake valves and exhaust valves and a crank shaft rotatably supported by a crank case and a plurality of bearing caps, wherein the transmission mechanism is configured as a chain-type transmission mechanism for making the engine compact. The restriction on the rotatably supporting position of a chain tensioner is moderated and the length of the chain tensioner is set at a relatively large value. The transmission mechanism is configured such that an endless chain, is wound around a drive sprocket, fixed on a crank shaft and a driven sprocket, fixed on a cam shaft. One end portion in the longitudinal direction of a chain tensioner, extending in the running direction of the chain is rotatably supported on one of the plurality of bearing caps in such a manner as to be elastically, slidably in contact with the chain.
