Title: Method for testing the functional safety of cooling circuit for IC engine
Inventor: HERRMANN PETER DR
IPC: G01M3/32
Filed: 1996-12-19
Abstract: The method involves filling the circuit to a specified coolant level and then the coolant is connected under pressure. To test for entrapped air in the circuit, the circuit is discharged with a predetermined pressure and afterwards the falling level of the coolant is inspected, to determine whether the level falls under a specified state with constant pressure. The pressure head is set for each circuit as a function of the overall elasticity of the circuit. The pressure test is carried out with cold coolant. The coolant circuit includes a compensation tank. An exhaust line between a radiator and the compensation tank is interrupted during the pressure test.
