Petrol engine compression tester is a diagnostic tool used to measure the compression pressure inside the cylinders of a petrol (gasoline) engine. It helps determine the engine's internal condition without dismantling it.
Functions
Measures the compression pressure of each engine cylinder.
Detects worn piston rings, leaking valves, or damaged pistons.
Identifies blown head gaskets or cylinder head leaks.
Compares compression between cylinders to locate faulty cylinders.
Diagnoses hard starting, rough idling, loss of power, and engine misfires.
Evaluates the overall condition and wear of the engine.
Confirms the quality of engine repairs after maintenance or overhaul.
Supports preventive maintenance by identifying engine problems before they become serious.
