    摘要: A fuel pressure control system for a vehicle comprises a pressure regulator module and a pressure increasing module. The pressure regulator module regulates a fuel pressure supplied to an engine to a first predetermined pressure during an engine running period. The pressure increasing module selectively increases the fuel pressure to a second predetermined pressure during the engine running period when a counter value is one of greater than and less than a predetermined final value. The second predetermined pressure is greater than the first predetermined pressure, and the counter value is set to the predetermined final value after the engine is started for a first time after being assembled.

    摘要: An engine system includes a status determination module and an open-loop fuel control module. The status determination module determines whether a first ignition fuse is in a failure state. The open-loop fuel control module disables a first plurality of fuel injectors and actuates a second plurality of fuel injectors based on a first air/fuel (A/F) ratio when the first ignition fuse is in the failure state, wherein the first ignition fuse and the first plurality of fuel injectors correspond to a first cylinder bank, and wherein a second ignition fuse and the second plurality of fuel injectors correspond to a second cylinder bank.
