Abstract

PURPOSE:To narrow the width between the left and right side running parts of a chain by an arrangement wherein a pair of cam shafts mounted on the upper part of an engine body are connected by means of the chain with a crankshaft mounted on the lower part of the engine body. CONSTITUTION:An engine body 1 comprises a crankshaft 2 mounted on the lower part thereof and a pair of front and rear cam shafts 3 mounted on the upper part thereof for air intake and exhaust system. Located between both the cam shafts 3 and somewhat under them is an intermediate shaft 4 having a common gear 6 engaging with gears 5 thereof and which is connected by a chain 7 with a crankshaft 2. This construction enables the whole width of the chain 7 including the shaft 4 to be narrowed relatively.

and the pair of camshafts, and these are generally installed in a continuous manner, and in such a case, the ceno as a whole tends to be relatively wide in the front and back direction, which is a disadvantage.・The purpose of the present invention is to obtain a device that does not have such inconveniences.
and a pair of camshafts 70 in front and rear of the O which are interlocked with this through a chain;
The camshaft is connected to the crankshaft via the chain at a common intermediate shaft that engages with the camshaft in gears.

The width of the crankshaft and each cam can be made relatively narrow as a whole, including the shaft, thus eliminating the above-mentioned disadvantages of the conventional one.Furthermore, by adjusting the gear module, shift coefficient, etc. as necessary, the crankshaft and each cam can be made relatively narrow. This has advantages such as being able to freely set the distance between the shafts.
