Title:
INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2020/054845
Kind Code:
A1
Abstract:
An internal combustion engine (28) is provided with: a crankcase (31) that demarcates a crank chamber; a cylinder block (32) that is joined to the crankcase (31) and guides linear reciprocating motion of a piston; a detection sensor (86) that has a detection end which is opposed to a to-be-detected body rotating about a rotation axis (Rx), and that detects the rotation angle of the crankshaft on the basis of the movement of the to-be-detected body; and a starter motor (29) that is disposed at a position deviated from the cylinder block (32) about the rotation axis (Rx) and along the outer surface of the crankcase (31), and that drives the crankshaft in accordance with supply of electric power. The detection sensor (86) is disposed in a space sandwiched, along the outer surface of the crankcase (31), between the starter motor (29) and the cylinder block (32). Accordingly, provided is an internal combustion engine that contributes to size reduction of a crankcase and that can favorably protect a detection sensor for detecting the rotation angle of a crankshaft.
