Problems solved by technology

As mentioned above, since the distance between the top surface of the cylinder head of the two units and the intersection point of the cylinder axes of the two units is different in the two units, there is a significant visual difference in the height of the two units, which often produces a sense of imbalance and damages the aforementioned functional beauty.

Abstract

To increase the functional beauty of an engine to improve the merchantability by making the heights of a pair of banks to be visually same as each other in a V-type engine for a motorcycle mounted with the V-shape in a plane orthogonal to an axis of a crank shaft, and having the heights of the banks different from each other. Side faces of cylinders 33A, 33B and side faces of dummy covers 42A, 42B covering at least a part of the cylinder heads 34A, 34B from side parts are provided with plural fins 40A, 44A, 40B, 44B arranged in the direction along the axes of the cylinders CA, CB in a state that the total numbers of the fins and mutual intervals of central lines of the fins are approximately equal to each other in both banks BA, BB. Distances LA2, LB2 respectively between the central line of the fin closest to the crank shaft 30 among the fins 40A, 44A, 40B, 44B, and an intersection CP of the cylinder axes CA, CB are approximately equally set in both banks BA, BB.

Description

technical field [0001] The present invention relates to a first unit in which a first cylinder head is combined with a first cylinder and a second unit in which a second cylinder head is combined with a second cylinder in a V-shaped arrangement in a plane perpendicular to the axis of the crankshaft, A V-shaped motor vehicle in which the distance between the intersection point where the first and second cylinder axes intersect in the plane and the top surface of the first cylinder head and the distance between the intersection point and the top surface of the second cylinder head are set to be different from each other. Background technique [0002] Such a V-type engine for a motorcycle is known in, for example, Japanese Unexamined Patent Application Publication No. 60-53625. In such an engine, in order to set the angle between the two units as small as possible, the intersection point of the axes of the two unit cylinders is arranged at a position deviated from the axis of t...
