Abstract

A V-2 engine includes two cylinder blocks mounted to a crankcase such that the respective cylinder axes of the cylinder blocks extend at an angle to each other and merge together at the axis of a crankshaft with the angle formed between the cylinder axes being divided into two angle parts by a centerline of the crankcase passing through the axis of the crankshaft, and an auxiliary machine mounted to the crankcase on the same side as one of the cylinder blocks when viewed from the axis of the crankshaft. In order to reduce the maximum width of the engine, the cylinder blocks are offset from a symmetric position with respect to the centerline of the crankcase to such an extent that a straight line circumscribing an outer end of a head cover attached to the one cylinder block and an outer end of the auxiliary machine is in parallel to the centerline of the crankcase.

Dependent claims

A V-2 engine comprising:

a crankshaft rotatably supported in a crankcase, the crankcase having a centerline passing through the axis of the crankshaft;
two cylinder blocks each having one head cover and mounted to the crankcase such that the respective cylinder axes of the cylinder blocks extend at an angle to each other and merge together at the axis of the crankshaft with the angle formed between the cylinder axes being divided into two angle parts by the centerline of the crankcase;
and
an auxiliary machine mounted to the crankcase on the same side as one of the cylinder blocks when viewed from the axis of the crankshaft,
wherein the cylinder blocks are offset from a symmetric position with respect to the centerline of the crankcase to such an extent that a straight line circumscribing an outer end of the head cover of the one cylinder block and an outer end of the auxiliary machine is in parallel to the centerline of the crankcase.
