  • Systems and methods for diagnosing an engine
    Patent number: 10845270
    Abstract: A method for diagnosing an engine in a vehicle, the method comprising: initiating a diagnostic test of the engine, disabling a cylinder of the engine, measuring a parameter indicative of performance of the engine, re-enabling the cylinder, comparing the parameter to reference data, assessing a status of the cylinder based on the comparison, and generating a diagnostic result based on the status of the disabled cylinder.
    Type: Grant

  • Consist adhesion level control system for locomotives
    Patent number: 10029704
    Abstract: A system for adjusting wheel adhesion levels on multiple locomotive axles in a rail vehicle consist is provided. The system includes a first controller associated with a lead locomotive and a second controller associated with at least one trailing locomotive. A wheel adhesion level sensor is configured to detect a low wheel adhesion level at an axle and transmit that information to the first or second controller. The first controller adjusts the load being delivered to the axles by the motor in response to the low wheel adhesion level.
