An adiabatic intake insulator inserted into a portion for connecting a carburetor to a small two-cycle gasoline engine or the like in which the generation of cracks due to stress concentration when bolts are fastened are restrained and the looseness of the fastening member due to the shortage of fastening torque is prevented. The intake insulator comprises: portions for supporting and securing a carburetor; an intake passage through which air-fuel mixture from the carburetor is introduced to the engine; portions for securing the intake insulator to the engine each comprising a through hole for a bolt and a counterbore for accommodating a head of the bolt; and a channel formed on a circumference of a bottom of the counterbore.

Intake insulator

A muffler for internal combustion engines is formed of vertically separable body sections so that the sound absorbing and filter members may be accessed easily for replacement and/or cleaning.

Exhaust muffler for internal combustion engine

A muffler with a catalyst A muffler closure is detachably attached to the muffler body of the muffler. A thermal insulation acoustic material layer and a catalyst layer are mounted to an inner surface of muffler closure through a porous holding plate along exhaust gas passage.

Muffler with a catalyst

Disclosed is a centrifugal clutch of the type that includes a driving side member, a driven side member and a plurality of clutch shoes each having one end connected to the driving side member, the other end being capable of being friction-engaged with the driven side member, the driving side member and the clutch shoes being integrally formed using a high specific gravity resin type composite material.

Centrifugal clutch

In a crank, a tri-iron tetroxide thin film is formed over at least one of the inner surface of a hole formed in a crank arm and one end of a crank pin, and the end of the crank pin is press fitted into the hole formed in the crank arm.

Crank

An aluminium alloy cylinder includes a cylinder body and a cylinder bore therein. An iron layer is electrodeposited on the wall surface of the cylinder bore by means of a high cathode current density so that a multiplicity of randomly oriented channels are formed in the electrodeposited iron layer.
