20090139989 | TANK VENTING DEVICE FOR A MOTOR VEHICLE - A tank venting device for a motor vehicle has a fuel tank, a fuel vapor accumulator for storing fuel vapors escaping from the fuel tank and a connection line, via which the fuel vapors may flow from the fuel tank into the fuel vapor accumulator. Furthermore, an overpressure line having an overpressure valve is provided, via which the fuel vapors may flow from the fuel tank into the fuel vapor accumulator when the overpressure valve is open. An attachment of the connection line on the fuel vapor accumulator and an attachment of the overpressure line on the fuel vapor accumulator are situated at different points on the fuel vapor accumulator. The operational reliability of a tank venting procedure may thus be increased and the adsorption capacity of the fuel vapor accumulator may be used better. | 06-04-2009 |
20090204309 | METHOD AND DEVICE FOR CHECKING THE OPERABILITY OF A TANK VENTING DEVICE FOR AN INTERNAL COMBUSTION ENGINE - The tank venting device has a fuel vapor reservoir connected to a fuel tank to deliver escaping fuel vapors to the fuel vapor reservoir, and is connected to the internal combustion engine in such a manner that during a tank venting operation the fuel vapors contained in the fuel vapor reservoir are delivered as regeneration gas. To check the operability of the venting device the fuel concentration in the regeneration gas is ascertained at a minimum of two different points in time during the venting operation. The fuel concentration values in the regeneration gas are compared with respective reference values representing the regeneration gas fuel concentration in the situation in which no additional fuel vapors are delivered during the venting operation. The assessment of the venting device operability is carried out by comparison of the values ascertained for the fuel concentration in the regeneration gas with the reference values. | 08-13-2009 |

20100059022 | Method, Device, and System for Operating an Internal Combustion Engine - 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. | 03-11-2010 |

20110174276 | Internal Combustion Engine and Method for Opertating an Internal Combustion Engine of this Type - During operation of an internal combustion engine system which has at least one sensor for measuring a hydrocarbon content of a gas stream in a line, a temperature is determined at the at least one sensor. If the temperature is greater than a prespecified temperature, the flow of gas through the line is interrupted. | 07-21-2011 |
20110226804 | Method for rapidly emptying the activated carbon filter while using an HC sensor (concentration change) - A method for rapidly emptying an activated carbon filter while using an HC sensor (concentration change). A device for a tank system, for a motor vehicle having the device for a tank system and to a method for emptying an activated carbon filter for a tank system. The concentration of volatile components which are flushed from the activated carbon filter is detected by a concentration sensor. The concentration sensor is used as an early warning sensor to prevent any disturbances of mixture production of an engine. | 09-22-2011 |
