[0002] The engine is the heart of the vehicle, and the high-pressure oil circuit is one of the most important parts of the engine. Leakage in the engine's high-pressure oil circuit is a common problem, which may cause the fuel to be unable to be effectively delivered to the engine, thus affecting the normal operation of the engine. At present, after the engine is produced, it is impossible to effectively test the air tightness of its high-pressure oil circuit. Utility Model Content
[0003] In order to make up for the deficiencies of the prior art, the utility model provides an engine high-pressure oil circuit leak testing tool which has the advantages of simple structure, convenient operation, accuracy, reliability and high efficiency.

DETAILED DESCRIPTION
[0016] The accompanying drawings are a specific embodiment of the utility model. This embodiment includes a mounting plate 1, on which two push-pull clamps 2 are fixedly mounted, and circular plugs 3 are mounted on the ends of the push-pull clamps 2. Three horizontal clamps 4 are fixedly mounted on the mounting plate 1, and conical plugs 5 are mounted on the ends of two horizontal clamps 4, and an air intake plug 6 is mounted on the end of another horizontal clamp 4. The push-pull clamp 2 is mounted on a push-pull clamp mounting plate 7, and the push-pull clamp mounting plate 7 is fixed on the mounting plate 1. The horizontal clamp 4 is mounted on a horizontal clamp mounting plate 8, and the horizontal clamp mounting plate 8 is fixed on the mounting plate 1. Two positioning pins 9 are fixedly mounted on the surface of the mounting plate 1. Two fixing plates 10 are fixedly mounted on the side of the mounting plate 1.
[0017] By using the engine high-pressure oil circuit leak test tool of the utility model, the product to be tested is positioned and placed on the mounting plate 1 through two positioning pins 9, and the two circular plugs 3, two conical plugs 5 and the air intake plug 6 are pushed by two push-pull clamps 2 and three horizontal clamps 4 to seal the oil circuit holes of the product, so that the oil circuit holes are sealed and leak-proof. An air intake pipe is connected to the air intake plug 6, and the air circuit is opened so that the oil circuit reaches a specified pressure. Then, the tool is placed in a bucket to check whether there are bubbles. If no bubbles emerge, the product is a qualified part with no leakage. If bubbles emerge, the product is an unqualified part with a leakage point. Check where the bubbles emerge, and the place where the bubbles emerge is the leakage point of the product. The manufacturing process of the product is modified through the leakage point to improve the quality of the product.
