Methods and systems are provided for adjusting injection timing of closely spaced multiple injections via a same injector. In one example, during an inter-injection spacing between a first injection and a second injection in a set of multiple injections being lower than a threshold period, an opening time of the second injection in the set of multiple injections may be adjusted based on another opening time of another second injection in a previous set of multiple injections.

Method and system for multiple injections

Methods and systems are provided for balancing a plurality of fuel injectors. In one example, a method includes adjusting port-fuel injecting parameters in response to a learned direct injector fueling error.

Methods and systems for improving fuel injection repeatability

Methods and systems are provided for an exhaust system. In one example, a method may include determining presence of a zone flow based on a comparison of a first exhaust sensor and a second exhaust sensor. The presence or absence of the zone flow may determine a rate at which an air-fuel ratio is adjusted.

Systems and methods for air-fuel ratio imbalance monitor

Methods and systems are provided for restarting an engine following an engine idle-stop. In one example, a method may include, prior to an engine restart following an idle-stop, adjusting a spark ignition timing based on an estimation of a fuel-air equivalence ratio (phi) and an estimation of a cylinder turbulence. Optimal spark ignition timing based on estimated phi and cylinder turbulence during engine restart may result in stabilized combustion and a torque output sufficient to at least partially relieve demand on the starting device.

Adjusted ignition timing for engine restart

Methods and systems for adjusting fuel injector operation according to changes in fuel pressure during inter-injection periods are described. The inter-injection period may be before and after fuel is injected to an engine. The methods and systems described herein may be suitable for direct and port fuel injectors.

Method and system for operating a fuel injector

Methods and systems are provided for engaging and disengaging an electromagnetic clutch of a two-speed accessory drive of an engine of a vehicle. In one example, a method comprises, responsive to an electrical demand being higher than a threshold electrical demand, operating an electric machine of the vehicle in a motor mode to reduce a speed of a grounding gear of a planetary gear set of a two-speed accessory drive (TSAD) of the vehicle; and engaging an electromagnetic clutch responsive to the speed of the grounding gear reaching a clutch engagement threshold speed.

Methods and systems for a two-speed accessory drive of an engine

Systems and methods for controlling a gasoline urea selective catalytic reductant catalyst are described. In one example, an observer is provided that corrects an estimate of an amount of NHthat is stored in a SCR. The amount of NHthat is stored in the SCR is a basis for generating additional NHor ceasing generation of NH.

Methods and system for controlling selective catalytic reductant catalyst of a gasoline engine

Systems and methods for starting and operating a direct injection engine are described. In one example, the air and fuel are injected into a pre-chamber of a cylinder of an engine while the engine is not rotating. The air and fuel are combusted in the pre-chamber to improve ignition of an air and fuel mixture in the cylinder.

Methods and system for cold starting an engine

Methods and systems are provided for balancing fuel delivery amongst all engine fuel injectors. In one example, a method may include selectively adjusting an injection timing of one or more fuel injectors of a plurality of fuel injectors to increase an inter-injection period between two consecutive fuel injections in response to a request to balance amounts of fuel injected by the plurality of fuel injectors.

Method and system for fuel injector balancing

Methods and systems are provided for reducing hot fuel vapor formation in a port injection fuel rail. In one example, a method may include operating a dual fuel injection system with at least a calibrated minimum amount of port fuel injection over a wide range of engine operating conditions, even as conditions change. A direct fuel injection amount is adjusted in accordance.

Methods and systems for port fuel injection control

Systems and methods for improving accuracy of an amount of fuel injected to an engine are disclosed. In one example, a maximum fuel injector holding current value is adjusted from a higher value to a lower value within a predetermined amount of time of an end of fuel injection. By adjusting the maximum fuel injector holding current value, it may be possible to reduce variation in an amount of fuel that is injected via the fuel injector.

Methods and systems for improving fuel injection

Methods and systems are provided for a fuel system. In one example, a method includes comparing a resistance of a solenoid coil of a direct injector to a threshold resistance. The method further includes selecting one of a transient or a steady-state pressure-based injector balancing (PBIB) model in response to the comparison.

Methods and systems for fuel injection control

Methods and systems are provided for estimating a temperature of a direct injector. In one example, a method may include estimating the temperature of the direct injector based on a resistance of a solenoid coil of the direct injector. In one example, a pulse-width of the direct injector during an opening phase is adjusted in response to the temperature.
