    摘要： A tank ventilation system is arranged in an internal combustion engine having an intake tract, the tank ventilation system comprising a hydrocarbon reservoir, a sensor, and a valve (42), wherein the valve (42) and the sensor are arranged in a fluid line. The fluid line couples the hydrocarbon reservoir to the intake tract. The sensor is designed to capture a hydrocarbon concentration (cHC) of a fluid in the fluid line. A captured value (W1) of the hydrocarbon concentration (cHC) is measured using the sensor. For the open valve (42), a mass flow (mF1) of the fluid flowing through the fluid line into the intake tract is captured or determined. An air/fuel ratio (LKV) of an air/fuel mixture fed to the internal combustion engine for combustion is determined. An estimated value (W2) of the hydrocarbon concentration (cHC) in the fluid line is determined according to the mass flow (mF1) of the fluid and the air/fuel ratio (LKV). The sensor is calibrated according to the captured value (W1) of the hydrocarbon concentration (cHC) and the estimated value (W2) of the hydrocarbon concentration (cHC).

    摘要： A tank ventilation system comprises a flushing line (38), off which a bypass (50) branches and into which the bypass opens out. A sensor (54) is arranged in the flushing line bypass to determine the concentration of hydrocarbons in a fluid in the flushing line. A hydrocarbon tank (34) is coupled via a first connector (36) to a first end of the flushing line and designed for coupling, via a second coupling (42), to a tank (6).

    摘要： A gas, whose mass flow is intended to be determined, flows through a flow channel (2). A device (1) for determining the mass flow has sound transducers (4) at the ends of a measurement path (5), which sound transducers (4) can be used to determine the delay time of sound signals (7, 8). The flow rate of the gas and the speed of sound can be determined from the delay time. A total mass flow is determined from the flow rate and also from pressure and temperature. The proportion of a further gas in the total mass flow can be determined from the speed of sound and the total mass flow can be corrected to the mass flow of the gas.
