Abstract
A device for an internal combustion engine for the combustion of a gasoline-based liquid fuel, having a tank, which is gas-conductively connected to the internal combustion engine with the aid of an exhaust gas line and a first shutoff valve, a hydrocarbon storage unit, which is gas-conductively disposed between the tank and the internal combustion engine with the aid of the exhaust gas line, for temporarily storing gaseous hydrocarbon contained in an exhaust gas escaping from the tank, and a hydrocarbon sensor, which is gas-conductively disposed between the tank and the internal combustion engine with the aid of the exhaust gas line, for measuring the hydrocarbon content in a purging air supplied to the internal combustion engine, the hydrocarbon storage unit being connectable to the free surroundings with the aid of a connecting line and a second shutoff valve.
