| 20090249888 | Device for Determining a Mass Flow - A device is provided for determining a mass flow of a first gas flowing in a flowing channel of an internal combustion engine of a motor vehicle. The device includes: sound transducers arranged at respective ends of a measuring path for providing sound signals, a temperature sensor for determining a temperature of an overall mass flowing in the flow channel, and an evaluation unit arranged downstream of the sound transducers. The evaluation unit is capable of carrying out the following: determining a flow rate of the overall mass and a speed of sound based on delay times of the sound signals, determining an overall mass flow based on the flow rate, the temperature, and a pressure of the overall mass in the flowing channel, ascertaining a proportion of a second gas flowing in the flow channel at a temperature above 10° C. and based on the speed of sound and the temperature, and correcting the overall mass flow to obtain the mass flow of the first gas. | 10-08-2009 |
| 20090290731 | Circuit arrangement for the bidirectional operation of a sound transducers disposed at the ends of a measuring section - A sensor circuit for a flow sensor comprises terminating impedances connected in parallel to the sound transducers and has a signal generator, which is configured as a power source. The circuit arrangement is suitable particularly for the operation of an airflow sensor in internal combustion engines. | 11-26-2009 |
| 20100000309 | Method and device for monitoring an exhaust-gas turbocharger - The present invention relates to a method and a device for monitoring an exhaust-gas turbocharger of an internal combustion engine. In order to create an inexpensive and also reliably operating method and a corresponding device for monitoring an exhaust-gas turbocharger, it is proposed that a sound transducer which is designed to record rotational-speed dependent turbocharger operating noise is provided, which sound transducer is connected to an electronic system for frequency analysis for the output of a turbocharger rotational speed signal. | 01-07-2010 |
