摘要： A method for detecting failures in a fuel system of a motor vehicle including monitoring a feed-forward table of a fuel pump controller that is electrically connected to a fuel pump of the fuel system. The fuel pump controller is electrically connected to a rail pressure sensor, which is coupled to the fuel injector rail. The actual fuel injector rail pressure measured by the rail pressure sensor is compared to a desired fuel injector rail pressure associated with the feed-forward table. The feed-forward table is adjusted if the actual fuel injector rail pressure is less than the desired fuel injector rail pressure. A fuel system error is signaled if an adjusted feed-forward table differs from an initial feed-forward table. A fuel system failure is signaled of the adjusted feed-forward table requires a saturation voltage of the controller.

摘要： An apparatus and method for controlling a throttle of an electronic throttle control-equipped engine including providing a throttle position feedback signal as a function of integer counts, each of the counts representing a resolution of a predetermined angle of actual throttle position, providing a desired throttle position command as a setpoint value being a function of half counts and generating an error signal representing a difference between the desired throttle position command value and the throttle position feedback signal value. A relay output signal is generated in response to the error signal, the relay output signal having one of two values depending upon a sign of the error signal and a direction of change of the error signal. A throttle actuator command is then generated as a function of the relay output signal value having a half count resolution.

摘要： A method for improving exhaust after treatment initial warm up during engine starting is presented. In one example, the method adjusts an engine air flow amount to a level where a desired substantially constant heat flux is provided by the engine to an exhaust after treatment device. The method may reduce fuel consumption and a need for a vacuum pump to provide vacuum to vacuum consumers of a vehicle during exhaust after treatment heating.

摘要： Methods and systems are provided for fuel systems including a gaseous fuel. Temporary flow restrictions in the fuel line of a first gaseous fuel may be addressed by temporarily shifting to cylinder operation with a second liquid fuel. Upon resumption of first fuel operation, if the flow restriction persists, a diagnostic code may be set and cylinder operation with the second fuel may be restarted.
