Embodiment Construction

[0025] The present invention will be further described below in conjunction with accompanying drawing.

[0026] Such as Figure 1 to Figure 6 The engine timing system inspection tool shown includes a crankshaft position fixing part 4 and a camshaft phase inspection part 8 .

[0027] Such as Figure 4 As shown, the crankshaft position fixing member 4 includes a crankshaft position fixing body 43, and one end of the crankshaft position fixing body 43 is provided with a boss 41 matching the notch on the edge of the signal plate 1, and the top surface of the boss 41 is from The direction from the inside to the outside is inclined downward, so that the boss 41 can be inserted into the notch on the edge of the signal plate 1 conveniently. A projection 42 for fixing the position of the crankshaft 2 is provided on the top surface of the crankshaft position fixing body 43 .

[0028] Such as Figure 5 with Image 6 As shown, the camshaft phase inspection part 8 is a cylindrical bod...

Abstract

The invention discloses an engine correct timing system inspection tool. The inspection tool comprises a crankshaft position fixing component and a camshaft phase inspection component. The crankshaft position fixing component comprises a crankshaft position fixing body. One end of the crankshaft position fixing body is provided with a boss which is cooperated with a gap on a signal disc edge. A top surface of the crankshaft position fixing body is provided with a bump used for fixing a crankshaft position. The camshaft phase inspection component is a cylinder body whose bottom end is sealed. A top end of the cylinder body is provided with a step. A bottom of the cylinder body is made of a transparent material. The bottom of the cylinder body is marked with scales used for detecting a camshaft position. The invention also discloses an engine correct timing system inspection method. By using the tool and the method of the invention, a oil leakage risk of a correct time system is reduced and work efficiency is increased.

Description

technical field [0001] The invention belongs to an automobile engine inspection tool, in particular to an engine timing system inspection tool and a method. Background technique [0002] At present, the purpose of the inspection of the timing system of the automobile engine is to determine whether the phases corresponding to the camshaft and the crankshaft are correct, and to troubleshoot the timing system failure. [0003] The steps for an existing timing system inspection include: [0004] (1) Disassemble the parts covering the timing system one by one; since the phaser or gear connected to the intake and exhaust camshafts, the crankshaft or the crankshaft sprocket are connected with each other by a chain, so turning the crankshaft in the timing system, The relevant parts will follow the rotation; [0005] (2) Turn the crankshaft in the timing system, and observe whether the timing mark set on the phaser or gear connected to the intake and exhaust camshafts and the timin...
