METHOD AND DEVICE FOR CONTROLLING BURNING OF RESISTOR FOR MEASUREMENT |
摘要 |
<p>Disclosed is a method of and a device for controlling a burn-off function of a measuring resistor, particularly heated wire or heated film in an air flow sensor of an internal combustion engine. The burn-off operation for fast cleaning the measuring resistor is normally made either periodically or in response to preset operational conditions of the engine. The invention interrupts this burn-off function when detrimental operational condition of the engine depending on the rotary speed has occurred. The stoppage of the burn-off function preferably occurs after a simultaneous detection of a predetermined temperature value detected by a sensor.</p> |
