Abstract

See full text

An internal combustion engine has a valve train and decompression mechanisms disposed in a valve chamber, and a fuel pump attached to a cylinder head. A pump cam for driving the actuating rod of a fuel pump through a swing arm, and a decompression mechanism opposite an end journal relative to the pump cam with respect to an axial direction parallel to the axis of the camshaft are formed on the camshaft in the valve chamber. One of the decompression mechanisms is disposed between the pump cam and an exhaust cam. The swing arm has a contact tip in contact with the pump, cam and a pushing tip in contact with the actuating rod at a position nearer to the exhaust cam than the contact part with respect to the axial direction. The pump cam comes into contact with an end bearing supporting the camshaft to restrain the camshaft from axial movement. The above structure serves to suppress increase in the length of the camshaft in the axial dimension of the valve chamber, and the projection in the axial direction of the fuel pump from the cylinder head 4, whereby the internal combustion engine can be formed in compact construction.
