  • Fuel pump health assessment system
    Patent number: 11598302
    Abstract: A pump health assessment system and a method for providing a pump health of a pump is disclosed. The method includes: determining that there is an imbalance in the pump; increasing pump flow from the pump; measuring a rail pressure of a fuel rail; determining if the rail pressure is substantially equal to an expected rail pressure profile; and in accordance with a determination that the rail pressure is not substantially equal to the rail pressure profile, outputting an indication of pump damage.
    Type: Grant
    Filed: November 24, 2020
    Date of Patent: March 7, 2023
    Assignee: Caterpillar Inc.
    Inventors: Daniel R. Puckett, Bradley S. Bashore

  • End-of-current trim for common rail fuel system
    Patent number: 9856840
    Abstract: Fuel is injected by energizing a solenoid of a fuel injector for an on-time that terminates at a first end-of-current timing. An end-of-current trim is determined at least in part by estimating a duration between an induced current event in a circuit of the solenoid and a valve/armature interaction event. An induced current event occurs when an armature abruptly stops, and a valve/armature interaction event occurs when the armature couples with or de-couples from the valve member. Fuel is injected in a subsequent injection event by adjusting the end-of-current timing by the end-of-current trim.
