Benefits of technology

[0007] The primary objective of the invention is to provide an improved cam shaft intake angle examining device to fast measure the intake angle so as to save time and manual energy.

Problems solved by technology

However, the current calculation technique is too troublesome and wastes too much time.
As stated earlier, this technique takes too much time and involves a lot of manual energy.

Embodiment Construction

[0016] With reference to FIGS. 1 and 2, a cam shaft intake angle examining device in accordance with the present invention includes a base 1, a measuring disk 2, and an adjusting rod 3. The engine 4 with a cam shaft 41 to be tested is a two-stroke diesel engine. The engine 4 is first secured in the base 1. The adjusting rod 3 is used to position the cam shaft 41 at an initial position (0 point). A connecting block 22 is placed on the cam shaft 41. A rotation disk 21 is measured and fixed on the connecting block 22. After the adjusting rod 3 is taken away from the base 1, the engine 4 is ready for test.

[0017] The base 1 is defined with a fixing recess 12. The fixing recess 12 is so defined that it is adapted to mate with the shape of the cam shaft 41. The base 1 further has a ring 11 with scales that has a prevision of 0.1 degrees. A fixing hole 111 is defined in the ring 11 and a connecting hole 112 is defined in a bottom defining the fixing hole 111 to communicate with the connect...

Abstract

An intake angle examining device for an engine cam shaft includes a base adapted for receiving the engine, a measuring disk pivotally connected to the base for allowing the cam shaft to extend therethrough and an adjusting rod extendable into a cylinder of the engine to secure the cam shaft. The engine to be tested is secured in the base and the cam shaft is extended through and secured in the rotation disk. The adjusting rod is extended into the cylinder to fix the cam shaft and is removed when the engine is tested.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a cam shaft intake angle examining device, and more particularly to a diesel engine cam shaft intake angle examining device such that the intake stroke is able to precisely coordinate with different strokes of the engine. [0003] 2. Description of Related Art [0004] An engine provides power to vehicle, vessels and aircraft so that all these different transporting bodies are able to move. Based on the fuel consumed, some are gasoline engines and the other diesel engines. Based on the number of strokes each cycle, some engines are four-stroke engines and some two-stroke engines. As is generally known, the four strokes of the engine are intake, compression, explosion and exhaust. Thus, it is to be noted that the intake and exhaust occur at the same time to the diesel engine. Therefore, observation of the activation / deactivation of the intake and the traveling distance of the piston is ab...
