Abstract
An arrangement is provided for use with an internal combustion engine. The arrangement includes an intake tract for the internal combustion engine and a valve that is fluidly connected to the intake tract. An activated carbon filter is located upstream from the intake tract and the valve. The valve is connected to the carbon filter by an intake line. When the valve is open, fluid can flow from the activated carbon filter into the intake tract. A pressure sensor measures upstream pressure (p) in the intake line. A pump helps generate the pressure (p) in the intake line. The valve is connected to the intake tract so they cooperate together to form a cavity that is connected to the intake line such that when the valve is closed, the pressure in the cavity is the pressure (p).
