Abstract (en)
[origin: EP1327762A2] The method involves maintaining a pressure greater than ambient pressure in a pressure region after turning off the engine and checking the functionality of a cut-off valve, which must be closed to maintain the pressure, by detecting the pressure in the pressure region after turning off the engine, driving the valve to open if functioning correctly, measuring the pressure again after a defined time and comparing with the previous pressure. The method involves maintaining a pressure greater than ambient pressure in a pressure region after turning off the engine and checking the functionality of a cut-off valve (50) device, which must be closed to maintain the pressure, by detecting (64) the pressure in the pressure region after turning off the engine, driving the valve device to open if functioning correctly, measuring the pressure again (68) after a defined time and comparing (74) with the previous pressure. Independent claims are also included for the following: a computer program for implementing the inventive method, a control and/or regulation device for operating an internal combustion engine and an internal combustion engine with an inventive control and/or regulation device.
