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.

摘要： To improve a mounting configuration for a chain guide of a cam chain for transmitting power to a power system of an internal combustion engine to make mounting of a chain guide and a cylinder block simple and easy. A mounting device for a cam chain guide for an internal combustion engines constructed such that rotation of a crank shaft is transmitted to a cam shaft provided externally of a cylinder bore by a cam chain 3 to operate an intake/exhaust valve through a push rod and a rocker arm. A first protrusion provided in the vicinity of a lower end of a chain guide is fitted into a first locating groove provided in the vicinity of a crank shaft of a crank casing, and a second protrusion provided in the vicinity of an upper end of a chain guide is fitted into a second locating groove provided in a lower surface of a cylinder block and gradually enlarged from a protrusion fixed position toward an opening.
