Abstract

The invention belongs to the automobile part technology field and provides an engine gas distribution phase detection apparatus. The apparatus comprises a dial indicator and a pointer. The dial indicator is installed on one side of a cylinder cover, wherein the side is close to an air valve. A measuring head of the dial indicator vertically abuts against the air valve. A driving terminal of a camshaft, which is stretched out of the cylinder cover, is connected to a dial. The driving terminal is connected to a driving mechanism driving the camshaft to rotate about an axis. The pointer is installed on the cylinder cover and is extended to the dial along a radial direction of the dial. Through adding the driving mechanism, the driving terminal directly drives the camshaft to rotate so as to detect a lift maximum value and an air valve phase angle. By using the above structure, detection processes are saved. If the phase angle does not accord with a design requirement, only parts of a cylinder cover portion need to be dismounted. Working time is saved and assembling efficiency and production efficiency are increased.

Description

technical field

[0001] The invention belongs to the technical field of automobile detection, and in particular relates to an engine valve phase detection device and method. Background technique

[0002] The engine valve mechanism is an important part of the engine, generally composed of camshafts, rocker arms, analog tappets, valve guides, valves, valve springs and other components. The main function of the gas distribution mechanism is to open and close the intake valve and exhaust valve of each cylinder regularly according to the requirements of the engine working cycle and ignition sequence, so that the fresh charge can enter the cylinder in time, and the exhaust gas is discharged from the cylinder in time. And the sealing of the combustion is guaranteed during the expansion stroke. The opening and closing of the valve must have precise control, which is mainly related to the valve timing. There are two points to ensure the timing of the gas distribution: one is the des...
