Embodiment Construction

[0016] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0017] figure 1 The lower surface (the surface in contact with the cylinder head) of the cylinder head cover constructed according to the present invention is shown. This cylinder head cover 1 is applied to an in-cylinder injection internal combustion engine that directly injects fuel into a combustion chamber, and is configured such that the upper surface of an upper cam holder (not shown) on which a fuel injection valve is fixed is raised from the upper surface of the cylinder head cover 1 The central opening 2 is exposed.

[0018] The cylinder head cover 1 is formed with an annular raised portion 3 for defining a cavity that surrounds an opening 2 through which a mounting portion of a fuel injection valve is exposed. The cylinder head cover 1 as figure 2 As shown, a sealing member 6 ( figure 2 ), in a state where it is in contact with the upper surfac...

Abstract

Provided is a cylinder head cover of an internal combustion engine in which a rotation detector can be attached without impairing maintenance and detection accuracy. A metal cylinder head cover (1) is fixed to a cylinder head (7) of an internal combustion engine via a bolt (9) via an elastic member (seal member 6), and is provided with a detector (16) for detecting the rotation of a camshaft (12) A boss portion (8) for inserting the bolt is provided in direct contact with the cylinder head, and the boss portion is connected with the mounting portion of the detector.

Description

technical field [0001] The present invention relates to a cylinder head cover of an internal combustion engine, and more particularly to a cylinder head cover which is attached to a cylinder head via an elastic member and has a mounting portion for a detector for detecting rotation of a camshaft. Background technique [0002] As a detection device for the rotation angle of the crankshaft, etc., it is known to detect passage of a protrusion of a pulse gear provided at the shaft end of a camshaft that rotates synchronously with the crankshaft using an electromagnetic non-contact detector. Furthermore, in order to improve the maintainability of the detector, it is also known to provide a fixing part of the detector on the cylinder head cover covering the valve mechanism (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Unexamined Patent Publication No. 10-37835 (FIG. 7) [0004] However, the cylinder head cover is generally attached to the cylinde...
