Title:
INTERNAL-COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/180560
Kind Code:
A1
Abstract:
An internal-combustion engine (27) is provided with: a piston (57) which is accommodated in a cylinder (58) and which reciprocates along a cylinder axis C; a connecting rod (61) connected to the piston (57); a crankshaft (62) connected to the connecting rod (61); a detected body (63) which rotates integrally with the crankshaft (62); and a detecting sensor (64) which is oriented toward the trajectory of the detected body (63) and generates a pulse signal in accordance with the movement of the detected body (63). An axis (64a) of the detecting sensor (64) is positioned in a range of ± 45° about an axis of rotation (33) of the crankshaft (62) relative to a virtual plane (65) orthogonal to the cylinder axis C. In this way it is possible to provide an internal-combustion engine achieving a detecting sensor layout which is not readily influenced by the reciprocating motion of the piston when detecting the crank angle.
