Title:
CAMSHAFT, CAM ANGLE DETECTION DEVICE, AND INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2015098819
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a camshaft, an internal combustion engine, and a cam angle detection device, capable of more accurately detecting a cam angle while saving a space of the internal combustion engine.SOLUTION: An intake camshaft 11 includes a sensor rotor 16 having a protrusion 17 as a detection target of a cam angle sensor 18 on an outer peripheral surface thereof, and a plurality of cams 15, and a nose 19 of the plurality of cams 15 includes a long diameter part in which a length L1 in a radial direction of the intake camshaft 11 from an axis O of the intake camshaft 11 to an outer peripheral surface of the nose 19 of the cam 15 is longer than a radius r of a base circle 22 of the sensor rotor 16. The long diameter part (nose 19) of a cam 151 closest to the sensor rotor 16 of the plurality of cams 15 is positioned in a region R sandwiched by two virtual lines L4 and L5 extending through both ends 23 of the protrusion 17 of the sensor rotor 16 from the axis O of the intake camshaft 11 in an axial view of the intake camshaft 11.
