摘要： A method and system for fuel rail compensation in a returnless electronic fuel pump arrangement provides modification of fuel pulsewidth based on measured or inferred rail temperature. The present invention applies fuel pulsewidth control modifiers to enlarge the fuel pulse to increase the quantity of fuel being delivered to at least one fuel injector to offset any drop in fuel density and injector performance caused by fuel rail temperature. The present invention generates these modifiers separate from a vehicle's normal fuel delivery system adaptive control process, thereby eliminating any unnecessary adaptive processing and limiting of adaptive control range.

摘要： Methods and systems are provided for restarting an engine when a high pressure fuel pump is degraded. In response to an indication of high pressure fuel pump degradation, fuel may be injected during an intake stroke, rather than a compression stroke, for a selected number of combustion events since the engine restart. By shifting to an intake stroke injection, the engine may be started even when sufficient fuel rail pressures are not available.

摘要： A system and method for controlling an internal combustion engine during starting use position sensor information in addition to cylinder combustion information to transition from simultaneous fueling to sequential fueling by selecting a cylinder to receive a first sequential fuel injection. Embodiments include a system and method for controlling a sequentially fueled port injected internal combustion engine that contingently select a cylinder to receive a first sequential fuel injection based on position information indicating that the cylinder received a simultaneous fuel injection during its intake stroke. Engine rotational speed is monitored to detect combustion and determine which cylinder fired first. A first sequential fueling pulse is provided to the contingently selected cylinder unless a preceding cylinder in the firing order fires first.

摘要： An approach is provided for compensating engine fueling during starting conditions in which positive valve overlap is enabled early in the start. In one example, the valve timing is adjusted to increase positive overlap during cold starting conditions, and fuel adjustments are provided to compensate for the evaporation effects of the increased residual push-back.

摘要： An electronic valve actuation system and control method is described. The valve timing is changed between early and late intake valve closing depending on engine operating conditions. Further, valve timing is adjusted to control engine airflow or engine torque. Finally, air-fuel ratio is adjusted based on feedback from an exhaust gas oxygen sensor as well as an estimate of air, fuel, and residual exhausted from cylinders operating with late valve closing (after bottom dead center) timing.

摘要： A system and method of improving the control quality of a vehicle engine having a rotatable and positionable crankshaft by prioritizing tasks to be performed by a microprocessor preprogrammed with an inventory of foreground and background engine tasks affecting the efficiency and performance of the vehicle. The invention includes sensing the speed of rotation of the crankshaft to provide a first, second, or third signal indicative of respective low, medium, or high crankshaft speeds, sensing the position of the crankshaft to provide a fourth signal of the crankshaft position, and processing these signals. The foreground tasks are selected if the fourth signal is received. A first set of the foreground tasks are selected if the first signal is received. A second set of the foreground tasks are selected if the second signal is received. A third set of the foreground tasks are selected if the third signal is received.
