Abstract: A method and test device for recognizing detecting whether a mass air flow meter of intake air of an internal combustion engine is defective is provided. In the method and device, a test procedure is executed using a pilot controller while a mixture controller that is used in non-test engine operation is deactivated. The pilot controller for the mixture of fuel and air in the respective cylinders outputs control values which, during normal operation of the internal combustion engine via the mixture control, are varied on the basis of a mixture deviation of the current mixture from a stoichiometric mixture. The engine is set to one or more different idling speeds and at each respective idling speed the mixture deviation is detected. If the detected mixture deviation(s) (i'lA.) satisfy a predetermined criteria thresholds, the air flow meter is identified as defective. A method and test device for recognizing detecting whether a mass air flow meter of intake air of an internal combustion engine is defective is provided.

Abstract: A flow metering apparatus comprising a temperature sensing system for use to measure temperature of fluid includes temperature measurement components and temperature sensing components in close proximity to one another and to the flow of fluid. The components can include a temperature measurement member close-coupled to a processor member, each disposed on a circuitized substrate. This configuration exposes a temperature sensor element to the same dynamic temperature conditions as the processor member, thus reducing measurement error that might manifest in response to different temperature gradients proximate the respective components. A storage memory may be used to permit the temperature sensing system to store and/or retain data that relates to calibration as a dynamic system over the entire operating range of the sensor element. The calibration data may then be accessed from the storage memory to improve accuracy and operation of the flow metering apparatus. A flow metering apparatus comprising a temperature sensing system for use to measure temperature of fluid includes temperature measurement components and temperature sensing components in close proximity to one another and to the flow of fluid.

Abstract: Thermal type flow rate meters for measuring the flow rate of intake air of an internal combustion engine of a motor vehicle or the like have encountered a problem of an increase in pulsation errors during high engine speed and high pulsation. Meanwhile, digitally recovering responses has posed a problem in which pulsation performance is liable to become worse, affected by variation in a clock or the like. The sensor is provided with means for transferring a response variation factor to the engine control unit. The engine control unit is provided with logics for automatically determining the variation factor and correcting a response. Means for detecting a backflow occurrence is provided and a parameter for a response recovery is changed before and after a backflow occurrence. The sensor is provided with a selecting means by which a sensor response can be selected and obtained and the engine control unit is provided means for allowing selection of a response.

Abstract: A gas flow meter comprises a meter body, a tube, and a sensing unit. The sensing unit includes a base connected with one end of the tube; a speed transducer penetrating the base; a temperature transducer penetrating the base; a temperature compensator penetrating the base; and a microcontroller accommodated inside the meter body. The microcontroller is electrically connected with the speed transducer, the temperature transducer and the temperature compensator. The temperature transducer only functions to detect the temperature of the surrounding gas. The temperature compensator only functions to compensate the speed transducer for the temperature drop thereof. Each of them functions independently. Once the temperature of the speed transducer lowers, the temperature compensator directly compensates for the temperature drop, whereby the statistic error value is effectively decreased. A gas flow meter comprises a meter body, a tube, and a sensing unit. The sensing unit includes a base connected with one end of the tube; a speed transducer penetrating the base; a temperature transducer penetrating the base; a temperature compensator penetrating the base; and a ...more ...less
