Compression Pressure Testers for Gasoline and Diesel Engines

The compression pressure test is an important mechanical diagnostic procedure for evaluating the pressure build-up in individual cylinders of an internal combustion engine. Abnormal or significantly divergent measurement values can indicate problems with valves, piston rings, the cylinder bore, or other components of the combustion chamber. However, the specific cause cannot always be clearly determined by the compression measurement alone.

Leitenberger Autotest Equipment offers professional compression pressure testers for gasoline and diesel engines in both analog and digital versions, as well as systems with Bluetooth transmission and documentation capabilities. A variety of measurement ranges and a comprehensive range of adapters enable their use on passenger car, commercial vehicle, industrial, and marine engines. If the compression test identifies problematic cylinders, a subsequent engine pressure leak test can help further narrow down the cause.
