Patent number: 12215640Abstract: An internal combustion engine system is described herein. The system uses compressed air from a compressor to purge at least a portion of a fuel from an internal combustion engine. During a purge operation, a controller opens and closes an injector of the fuel to be purged to allow the compressed air from the compressor to push at least a portion of the fuel back into a fuel tank through the injector. The controller deenergizes a fuel pump that pumps the fuel to be purged, allowing the pressure of the fuel that is to be purged to reduce to a pressure that allows the compressed air to flow into the injector.Type: GrantFiled: May 23, 2023Date of Patent: February 4, 2025Assignee: Caterpillar Inc.Inventors: Michael David Gerstner, Arnold Myoungjin Kim

Patent number: 12215644Abstract: An engine controller inhibits a fuel cut when it is predicted that a lockup clutch is released after elapse of a predetermined period of time, at the time of the starting of the fuel cut. Specifically, engine controller is configured to predict (calculate) the vehicle speed after a predetermined period of time, and inhibit the fuel cut when the predicted (calculated) vehicle speed after the predetermined period of time is equal to or less than a lockup release speed. With this, it is possible to avoid a situation in which an internal combustion engine restarts fuel supply immediately after the fuel supply has been cut. Consequently, in the vehicle, the occurrence of the torque fluctuation of internal combustion engine resulting from fuel cut recovery can be suppressed, a change in acceleration in the front-rear direction of the vehicle is suppressed, and a deterioration in driving performance can be suppressed.Type: GrantFiled: June 3, 2021Date of Patent: February 4, 2025Assignee: NISSAN MOTOR CO., LTD.Inventors: Masahiro Omori, Kazuki Hirasako
