| 20080216787 | Method for starting an internal combustion engine - To achieve a reliable and exhaust-optimized combustion starting already from the beginning of a combustion phase in the startup of an internal combustion engine, the internal combustion engine is brought to a target speed by an electric motor in a drag phase, the target speed being higher than the previously known starting speed. The target speed corresponds approximately to an idling speed assigned to the internal combustion engine, for example. After exceeding the starting speed, first a mixture enrichment is determined, taking into account a prevailing state of a wall film here in particular. Only after reaching the target speed is the fuel metered and does the combustion take place in the combustion phase. The fuel is metered here in particular on the basis of the mixture enrichment determined after exceeding the starting speed. | 09-11-2008 |
| 20090211560 | Method for Operating a Tank System Comprising a Tank, and Tank System - The invention relates to a method for operating a tank system, in particularly of a motor vehicle, comprising a tank. According to the invention, said tank system has an adsorption filter for capturing the volatile substances exiting the tank. The loading of the adsorption filter suggests that the tank is being filled. | 08-27-2009 |

| 20100063709 | METHOD AND DEVICE FOR OFFSETTING BOUNCE EFFECTS IN A PIEZO-ACTUATED INJECTION SYSTEM OF AN INTERNAL COMBUSTION ENGINE - The invention relates to a method and a device for offsetting bounce effects in a piezo-actuated injection system of an internal combustion engine using a control valve actuated by a piezoelectric actuator. The inventive method comprises the following steps: detecting an actual bounce behavior of the control valve, and determining and offsetting a deviation between the actual bounce behavior and a desired bounce behavior of the control valve, thereby generating an actuation information for the control valve which influences a speed characteristic of a needle of the control valve. The invention also relates to a device for carrying out the inventive method. | 03-11-2010 |
