  • Patent number: 10947919
    Abstract: A fuel injector controller is disclosed. The fuel injector controller may determine respective values of a set of parameters of the engine; process, using a neural network, the respective values to determine a target fuel output of a fuel injector, wherein the neural network is configured to determine the target fuel output based on the set of parameters being an input layer of the neural network; determine, based on an output of the neural network, the target fuel output; and provide the determined target fuel output to the fuel injector to permit the fuel injector to inject fuel according to the target fuel output.
    Type: Grant
    Filed: August 26, 2019
    Date of Patent: March 16, 2021
    Assignee: Caterpillar Inc.

  • Patent number: 10669952
    Abstract: A cylinder cutout system for an internal combustion engine is provided. The system may include a plurality of cylinders having a first pattern of cylinders and a second pattern of cylinders. Additionally, a fuel governor operatively coupled to a plurality of fuel injectors may regulate an amount of fuel received by the plurality of cylinders. The system may further include a plurality of sensors configured to collect a set of engine data and a controller communicably coupled with the plurality of fuel injectors, the fuel governor and the plurality of sensors. The controller may be programmed to detect a start-up condition of the engine and to execute a cylinder test cycle on at least a portion of the plurality of cylinders based on a positive detection of the start-up condition. The controller may activate one of the first or second patterns of cylinders based on the cylinder test cycle results.
