Abstract

The equipment is designed to measure the air leakage through rings valves and liners of the internal combustion engine. The cylinder (1) contains a concentric piston (2) and inlet and exhaust valves (3, 4). A source of air pressure (7) is connected to the cylinder through test circuit valves (5, 8) between which is a feed line (6) with a temporary link (9) and two manometer U-tubes (10, 12) the first of which measures the pressure difference between the applied source and the residual cylinder pressure and the second of which measures the cylinder pressure relative to the atmosphere. From the pressure readings, the leak rate may be determined.
