  • Engine starter predictive maintenance system
    Patent number: 8534082
    Abstract: An engine starter system that predicts when starter failure is imminent. The engine starter system monitors engine starter crank speed, battery voltage and ambient air temperature. The crank speed, battery voltage and ambient air temperature are communicated to a controller which compares the crank speed for the measured battery voltage and air temperature to a predicted crank speed for the measured battery voltage and air temperature. If the crank speed is lower than the predicted crank speed, a signal is sent to an alarm.
    Type: Grant
    Filed: July 20, 2010
    Date of Patent: September 17, 2013
    Assignee: Thermo King Corporation
    Inventors: Daniel L. Price, Greg R. Truckenbrod, Ross T. Nelson
