    摘要: A tank ventilation system having an intake tract, the tank ventilation system including a hydrocarbon reservoir, a sensor, and a valve. The valve and the sensor are arranged in a fluid line that couples the hydrocarbon reservoir to the intake tract. The sensor captures a hydrocarbon concentration of a fluid in the fluid line. A captured value of the hydrocarbon concentration is measured using the sensor. When the open valve, a mass flow of the fluid flowing through the fluid line into the intake tract is captured or determined. An air/fuel ratio of an air/fuel mixture fed to the internal combustion engine is determined. An estimated value of the hydrocarbon concentration in the fluid line is determined according to the mass flow of the fluid and the air/fuel ratio. The sensor is calibrated according to the captured value of the hydrocarbon concentration and the estimated value of the hydrocarbon concentration.

    摘要: A device and a method for operating an internal combustion engine having at least one cylinder and a tank ventilation system with a line designed to provide pneumatic communication between the tank ventilation system and the at least one cylinder. The line has at least one sensor for determining a hydrocarbon content of a gas flow. A determination, as a function of a measurement signal from the sensor, of a hydrocarbon content of a gas flow flowing from the tank ventilation system to the at least one cylinder is performed. At least one characteristic variable for a fuel quantity to be metered is determined as a function of the determined hydrocarbon content. A metering of fuel into the cylinder is determined as a function of the at least one determined characteristic variable.

    摘要: A tank ventilation system includes a flushing line, off which a bypass branches and into which the bypass opens out. A sensor is arranged in the flushing line bypass to determine a concentration of hydrocarbons in a fluid in the flushing line. A hydrocarbon tank is coupled via a first connector to a first end of the flushing line and designed for coupling, via a second coupling, to a tank.
