Operating internal combustion engine with filling lock involves inhibiting filling of fuel tank and/or engine starting if predefined minimum quantity in operating medium tank is reached

摘要

The method involves detecting the quantity in the fuel tank, detecting the operating medium at least relative to a predefined minimum quantity and generating a signal on reaching the minimum quantity with which filling fuel tank and/or starting the engine is prevented. The inhibition is removed after the operating medium tank has been re-filled.
