Cylinder Leak Detector It is suitable for most cars and trucks, especially for testing trucks and car models where the clearance is minimum. Check the leakage of the four stroke engine.Principle: When the engine is stationary and the piston is at the top dead center of the stroke, inject the required compressed air into the cylinder, and the air pressure drops to the specified value to reflect the time required for air leakage. The shorter the time, the greater the air leakage; on the contrary, the smaller the leakage.If the stabilized air is continuously supplied, the main part of the air leakage can be judged, so that the engine can be targeted for maintenance.
