ABSTRACT:
A V-type multicylinder internal combustion engine having a construction that front and rear cylinder blocks are arrayed in V shape longitudinally of a car body, a longitudinal center line of the rear cylinder block is made offset from the longitudinal center line of the front cylinder block, a crankshaft borne rotatably on a crank and transmission case enclosing a speed change gear therein is coupled to an input shaft of the speed change gear through a primary reduction gear and a clutch, the clutch is disposed on one side of the rear cylinder block, front and rear driving sprockets are mounted on an end of the crankshaft coming on the side isolated from the clutch so that the front driving sprocket comes inside the rear driving sprocket, and front and rear timing chains are laid between the front and rear driving sprockets and front and rear driven sprockets fixed on front and rear valve gear cam shafts provided on front and rear cylinder heads, respectively, which cylinder heads are fixed on the front and rear cylinder blocks through gaskets. With the above arrangement, the parts such as front and rear cylinder blocks, front and rear cylinder heads, front and rear gaskets and front and rear head covers become available for common use to realize reduction in manufacturing cost.
