This shows a screenshot of a diesel compression test done with a glow plug adaptor. The waveform from a diesel compression is very similar to a petrol compression test as we have no vacuum due to a normally open diesel throttle. The peak pressures, however, are far higher.
Image waveform shown below with injector disconnected.
Add diesel compression testing to your list of uses with this glow plug adaptor kit. It contains 15 different glow plug adaptors and the adaptor that connects them to our standard universal compression hose. This covers the majority of commonly used glow plug styles in modern diesel engines.
Diesel vehicles have become more advanced and testing of compression and engine efficiency is an everyday problem for technicians. Because of this issue, Pico Technology has worked to put together this fifteen-piece adaptor kit. As part of the kit included is a vehicle application list, covering models and engine codes for 30 vehicles.
