V-2 Engine

摘要

A V-2 engine includes two cylinder blocks (51L, 51R) mounted to a crankcase (11) such that the respective cylinder axes (Cy, Cy) of the cylinder blocks extend at an angle (&thetas;1+&thetas;2) to each other and merge together at the axis (L1) of a crankshaft (21) with the angle formed between the cylinder axes being divided into two angle parts (&thetas;1, &thetas;2) by a centerline (L2) of the crankcase passing through the axis of the crankshaft, and an auxiliary machine (47) 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 (L3) circumscribing an outer end (61a) of a head cover (61R) attached to the one cylinder block (51R) and an outer end (47a) of the auxiliary machine is in parallel to the centerline of the crankcase.
