A case member mounting structure, in which a case member ( ) is mounted to an engine body ( ) by fixing an outer circumference of the case member ( ) to the engine body ( ) with a plurality of fastening means ( ) to cover a power transmission mechanism, includes at least one projecting portion ( ) which projects from one or both of the inner wall surface of the case member ( ) and the outer wall surface of the engine body ( ) for contact with the other, and a seal member ( ) applied to the contact surface at the distal end of the projecting portion ( ).

Case member mounting structure

A tensioner device for an engine comprises a support member , a blade shoe coming into sliding contact with a timing chain having a base end section held by a cylinder block and a tip end section supported by the support member , and a leaf spring held by the blade shoe for pressing the blade shoe against the timing chain elastically. The support member is formed integrally with the cylinder block . The tip end section comes into sliding contact with a guide surface formed on the support member to be supported.

Tensioner device

An internal combustion piston engine has a main combustion chamber and an auxiliary combustion chamber connected by a torch passage, which is tapered end to end, the large end communicating with the main combustion chamber. Lean mixture is supplied to the main combustion chamber and rich mixture is supplied to the auxiliary combustion chamber. A spark plug ignites the mixture in the auxiliary combustion chamber, causing a torch flame to be projected through the tapered torch passage into the main combustion chamber near its center. A suction conduit, smaller in diameter and total area than any portion of the tapered torch passage, extends from a peripheral portion of the main chamber and intersects the tapered torch passage between its ends. Movement of the burning gases through the torch passage aspirates a flow of mixture from the main combustion chamber through the suction conduit into the torch passage.
