This compression pressure tester for petrol engines measures cylinder compression within a 0–20 bar range. It is a diagnostic tool for checking engine compression during maintenance and troubleshooting.
When investigating starting difficulties, uneven running or reduced engine performance, comparing compression readings between cylinders can help identify differences that require further inspection. Always assess the readings against the engine manufacturer's specifications rather than a universal pressure value.
