Abstract

The disclosed technology concerns a method to shut down an internal combustion engine further to a shutdown signal, said internal combustion engine comprising at least one exhaust valve configured to evacuate exhaust gas from the combustion and a compression brake device configured to open said exhaust valve when activated, and an oil circuit fluidically connected to the exhaust valve to provide oil at a predefined oil pressure, said method comprising the steps of, after receiving (100) the shutdown signal by the control unit: - if the oil pressure (Poil) is greater than or equal to a pressure threshold (Pth), activating the compression brake device (110) during the compression stroke, - if the oil pressure is lower than the pressure threshold, increasing (120) the oil pressure to the pressure threshold and activating the compression brake device during the compression stroke once the oil pressure has reached the pressure threshold.
