US 2016/0090907 A1 · INTERNAL COMBUSTION ENGINE FOR VEHICLE

Abstract

In an internal combustion engine for a vehicle wherein a crankshaft is supported for rotation on a crankcase and a speed change gear shaft which extends in parallel to the crankshaft and forms part of a transmission for changing the speed of rotational power from the crankshaft is supported for rotation on the crankcase such that it is disposed on one side of the crankshaft with a plurality of oil filters being mounted from the same direction to enhance the maintenance. A cover is coupled to a crankcase on one end side of a crankshaft in an axial direction, and a plurality of oil filters are attached to an outer side wall of the cover on the opposite side to a transmission with respect to the crankshaft and are disposed in an upwardly and downwardly juxtaposed relationship with each other.
