| 20090018751 | CONTROLLING CYLINDER MIXTURE AND TURBOCHARGER OPERATION - A method for controlling differences in exhaust gas residual amount for a two cylinder bank engine having at least one turbocharger is presented. In one example, the description includes a method for adjusting valve timing to reduce cylinder exhaust gas residual variation. | 01-15-2009 |
| 20090281713 | CYLINDER-BY-CYLINDER BALANCING OF COMBUSTION TIMING IN HCCI ENGINES - Various systems and methods are described for controlling fuel injection to a plurality of cylinders. One example method comprises during combustion timing imbalances among a plurality of cylinders carrying out homogeneous charge compression ignition combustion, adjusting a fuel injection amount in a first cylinder to adjust a combustion timing of the first cylinder in a first direction, and correspondingly adjusting a fuel injection amount in a second cylinder in a second direction to maintain average engine torque and reduce the imbalance. | 11-12-2009 |
| 20100012087 | SPARK TIMING ADJUSTMENT BASED ON VEHICLE ACCELERATION - Systems, methods and a processor are provided for adjusting the spark timing of an internal combustion engine. The systems, methods and processor include adjusting the spark timing of an internal combustion engine configured to power a vehicle toward peak torque timing based on an output of a longitudinal acceleration sensor configured to sense a longitudinal acceleration of the vehicle. | 01-21-2010 |
| 20100017096 | VEHICLE STABILITY AND SURGE CONTROL - In one example, a method is described for operating an engine of a vehicle, the engine having a combustion chamber. The method may include controlling a stability of the vehicle in response to a vehicle acceleration; and adjusting dilution in the combustion chamber of the engine to reduce surge in response to the vehicle acceleration. The dilution may be adjusted by adjusting cam timing, for example. | 01-21-2010 |
| 20100017101 | VEHICLE SURGE AND SPARK TIMING CONTROL - A method is described for operating an engine of a vehicle, the engine having a combustion chamber. The method may include controlling a stability of the vehicle in response to a vehicle acceleration; and adjusting spark timing in the combustion chamber of the engine in response to a knock indication, and further adjusting spark timing in response to the vehicle acceleration to reduce surge. | 01-21-2010 |
| 20100313847 | VEHICLE STABILITY AND SURGE CONTROL - In one example, a method is described for operating an engine of a vehicle, the engine having a combustion chamber. The method may include controlling a stability of the vehicle in response to a vehicle acceleration; and adjusting dilution in the combustion chamber of the engine to reduce surge in response to the vehicle acceleration. The dilution may be adjusted by adjusting cam timing, for example. | 12-16-2010 |
| 20100318279 | SYSTEM AND METHOD FOR CONTROLLING AN ENGINE DURING TRANSIENT EVENTS - Systems and methods for controlling an internal combustion engine include adjusting fuel delivered to a cylinder during a transient event by an amount indexed by number of combustion events after detecting the transient event. A base fueling parameter may be adjusted by an adaptive correction value indexed by combustion events after the transient event is detected, with the adaptive value determined using air/fuel ratio difference of previous combustion events during similar transient operating conditions associated with the same combustion event index number. Ionization sensor signal characteristics may be used to determine actual air/fuel ratios used to determine the air/fuel ratio difference and corresponding adaptive correction values. The adaptive values may be modified in response to a vehicle refueling event based on an amount of added fuel relative to existing fuel in the vehicle fuel tank. | 12-16-2010 |
| 20110000448 | CONTROLLING CYLINDER MIXTURE AND TURBOCHARGER OPERATION - A method for controlling differences in exhaust gas residual amount for a two cylinder bank engine having at least one turbocharger is presented. In one example, the description includes a method for adjusting valve timing to reduce cylinder exhaust gas residual variation. | 01-06-2011 |
| 20110132341 | Delay Compensated Air/Fuel Control of an Internal Combustion Engine of a Vehicle - A fuel control approach that compensates for time delays to increase exhaust gas sensor feedback response speed. | 06-09-2011 |
| 20110137539 | Multi-Component Transient Fuel Compensation - A method adjusts fuel injection to account for fuel puddling in the engine intake. The fuel is adjusted based on the ethanol content of the fuel in the puddle, and the make-up of the various fuel components in the puddle. In this way, it is possible to better account for the effects of these parameters on puddle evaporation. | 06-09-2011 |
