[0058] figure 1 The overall structure of the motorcycle according to one embodiment of the present invention is schematically shown. The motorcycle 11 includes a frame 12 . At the front end of the body frame 12 , a front fork 14 is steerably supported on a head pipe 13 . The front wheel WF is rotatably supported by a front fork 14 about an axle 15 . A handlebar 16 is coupled to the front fork 14 on the upper side of the head pipe 13 . On the rear side of the vehicle frame 12 , a swing arm 18 is swingably supported by a pivot frame 17 about a support shaft 19 extending horizontally in the vehicle width direction. The rear wheel WR is rotatably supported on the rear end of the swing arm 18 about an axle shaft 21 .

[0059]An internal combustion engine 23 is mounted on the body frame 12 between the front wheels WF and the rear wheels WR. The internal combustion engine 23 is configured as a V-shaped two-cylinder internal combustion engine. That is, the internal combustion en...

Abstract

The internal combustion engine (23) is equipped with: a crankcase (24) that supports the crankshaft (35) in a rotatable manner; a casing cover (54) that covers the side of the crankcase (24) in a liquid-tight manner; combined with the crankcase (24), A plurality of cylinders (25a, 25b) arranged in a V-shape intersecting each other at an inclination angle are arranged above a virtual horizontal plane (HP) including the rotation axis (Xc) of the crankshaft (35). The cylinder block (25); the object to be detected (56) which rotates integrally with the crankshaft (35); ) track and generate a pulse signal detection sensor (31) according to the motion of the object to be detected (56). This provides an arrangement structure of detection sensors that can detect the angular velocity of the crankshaft with high precision in a so-called V-type internal combustion engine.

Description

technical field [0001] The present invention relates to an internal combustion engine comprising: a crankcase rotatably supporting a crankshaft; a case cover liquid-tightly covering the sides of the crankcase; The cylinder block is located above the imaginary horizontal plane and divides a plurality of cylinders arranged in a V shape that intersect each other at an oblique angle. Background technique [0002] Patent Document 1 discloses a pulse sensor. The pulse sensor faces the outer rotor of the generator. The outer rotor is fixed to the front end of the crankshaft. One object to be detected is mounted on the outer surface of the outer rotor. The pulse sensor detects the object to be detected based on the rotation of the outer rotor, and generates a pulse signal while synchronizing with the rotation based on the detection of the object to be detected. [0003] Patent Document 2 discloses a ring gear (object to be detected) attached to a crankshaft of an internal combus...
