  • SYSTEM AND METHOD FOR ESTIMATING TURBO SPEED OF AN ENGINE
    Publication number: 20210293193
    Abstract: The speed of a turbocharger may be estimated using data from sensors that are readily available in most engine management systems. In some cases, a pressure measurement from a MAP sensor may be used, in combination with one or more computational models, to provide an efficient, lower cost estimate of turbo speed that can be used to control operation of the engine and/or the turbocharger.
    Type: Application
