Document Type and Number:
Japanese Patent JP2023150672
Kind Code:
A
Abstract:
To provide an attachment structure of a cam angle sensor of an internal combustion engine which can suppress the vibration of the cam angle sensor by improving the stiffness of a peripheral part of an attachment point of the cam angle sensor, and can prevent the lowering of the detection accuracy of a rotation angle of a camshaft.SOLUTION: An EGR housing 25 attached to a cylinder head 4 has: an upper wall 25D having attachment boss parts 28A, 28B attached with cam angle sensors, and continuously connected to a front wall 25A, a rear wall 25B and a left sidewall 25C; and a cylindrical EGR passage part 26 provided at the left sidewall 25C side, and having an EGR passage 26a in which an EGR gas flows. The EGR passage part 26 comprises: an EGR gas introduction port 26b provided at the front wall 25A, and introducing an EGR gas into the EGR gas passage 26a; and an EGR gas discharge port 26c provided at the rear wall 25B, and discharging the EGR gas from the EGR passage 26a. The boss attachment parts 28A, 28B are connected to the EGR passage part 26.SELECTED DRAWING: Figure 6
