Patent number: 11905908Abstract: A method for operating an engine fueling system to manage fuel in an accumulator supplying fuel to an engine including multiple cylinders comprising monitoring fuel load in the accumulator, determining that the engine is operating in a cylinder deactivation mode such as a skip-fire mode during which one or more fueling events to one or more of the cylinders is being skipped, and controlling a supply of fuel from a fuel pump to the accumulator during the cylinder deactivation mode operation. In embodiments, controlling the supply of fuel includes causing fuel to be supplied from the fuel pump to the accumulator if the monitored fuel load is less than or equal to a first fuel load, and causing fuel to be not supplied from the fuel pump to the accumulator if the monitored fuel load is greater than the first load value. Controlling the supply of fuel may comprise controlling the supply of fuel during each fueling event cycle of each deactivated cylinder.Type: GrantFiled: October 11, 2021Date of Patent: February 20, 2024Assignee: Cummins Inc.Inventors: Ross A.
