摘要： Various systems and methods are described for controlling engine operation. One method comprises, during a first variable displacement engine (VDE) mode in an engine having four cylinders, deactivating a first cylinder of the four cylinders and firing a second, third, and fourth cylinder of the four cylinders, each firing event separated by 240 degrees of crank angle (CA). The engine may be operated in a non-VDE mode by activating the first of the four cylinders and firing the first cylinder between the third and fourth cylinders.

摘要： Disclosed is a system for regulation of torque demanded from a prime mover of a vehicle, which prime mover responds to the torque demanded by delivering a dynamic torque. This dynamic torque is related by a gear ratio to a dynamic wheel torque which a power train comprising the prime mover imparts to at least one tractive wheel of the vehicle. The system regulates the torque demanded in such a way that a difference between the torque demanded and the dynamic torque is actively limited by employing feedback of the dynamic torque at an earlier time. The torque demanded at a time (t) for the regulation is limited to a maximum value which exceeds the dynamic torque at an earlier time by an offset value. The torque demanded is continuously varied according to the dynamic torque, so that power train oscillations in the vehicle are reduced in number and/or magnitude.

摘要： A control system for an engine includes a target air per cylinder (APC) module, a target area module, and a phaser scheduling module. The target APC module determines a target APC based on a target spark timing, a target intake cam phaser angle, and a target exhaust cam phaser angle. The target area module determines a target opening of a throttle valve of the engine based on the target spark timing, the target intake cam phaser angle, and the target exhaust cam phaser angle. The target area module controls the throttle valve based on the target opening. The phaser scheduling module determines the target intake and exhaust cam phaser angles based on the target APC. The phaser scheduling module controls intake and exhaust cam phasers of the engine based on the target intake and exhaust cam phaser angles, respectively.

摘要： A fuel control module transitions engine fueling from rich to lean. A catalyst fault detection module diagnoses whether a fault is present in an exhaust catalyst based on a response of an oxygen sensor to the transition. A prediction module generates a prediction based on a model and a set of possible target values. A cost module determines a cost for the set of possible target values based on comparisons of the prediction with minimum and maximums. Before the transition, a constraint module selectively adjusts at least one of the minimum and maximums for the fault diagnosis. Based on the cost, a selection module selects the set of possible target values from a group of sets of possible target values and sets target values based on the selected set of possible target values. An actuator module controls an engine actuator based on a first one of the target values.

摘要： A method of operating a gas or dual fuel engine having a plurality of cylinders, includes monitoring a characteristic of each of the plurality of cylinders during operation of the gas or dual fuel engine. The method also includes detecting a pre-ignition condition associated with one or more cylinders of the plurality of cylinders based on the monitored characteristic. The method further includes reducing fuel supply to the one or more cylinders having the pre-ignition condition. The fuel supply to remaining cylinders of the plurality of cylinders is increased, to maintain a constant power output of the gas or dual fuel engine. The method further includes adjusting an amount of air supplied to each of the plurality of cylinders based on the increased amount of fuel supplied to the remaining cylinders, to maintain an air-to-fuel ratio within a desired range.

摘要： A vehicle control apparatus performs an in-excess determination control by monitoring a drive power in-excess indicator at a time when a temporary in-excess state occurs which indicates that a drive power excess amount exceeds a predetermined value. As such, when a vehicle-dynamic safety parameter fulfills a prescribed condition, the vehicle control apparatus lowers an indicator threshold for determining an excess drive power continuation time from an original value to a lowered value. As a result, the excess drive power continuation time is determined as exceeding the indicator threshold, which indicates that a drive power of a vehicle is in excess, and a fail-safe instruction signal output is brought forward from an original timing to an earlier timing. Therefore, when a degree of dangerousness of a vehicle behavior is estimated to be relatively high, a fail-safe action is promptly taken.

摘要： Methods and systems are provided for improving vehicle torque control accuracy. Data points of an engine torque data set are adjusted en masse by an on-board vehicle controller while also being adjusted individually by an off-board controller. By adjusting engine operation based on a torque data set that is updated by each of the on-board and off-board controllers, engine torque errors can be reliably determined and compensated for.

摘要： Fuel management system for efficient operation of a spark ignition gasoline engine. Injectors inject an anti-knock agent such as ethanol directly into a cylinder of the engine. A fuel management microprocessor system controls injection of the anti-knock agent so as to control knock and minimize that amount of the anti-knock agent that is used in a drive cycle. It is preferred that the anti-knock agent is ethanol. The use of ethanol can be further minimized by injection in a non-uniform manner within a cylinder. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency or the engine.

摘要： Some embodiments relate to an internal combustion engine that includes a combustion chamber and a rotating component. The internal combustion engine further includes a sensing system that detects an angular position of the rotating component. A controller calculates a ratio between air and fuel in the combustion chamber based on the detected position of the rotating component. As an example, the rotating component may be a crankshaft where the controller calculates a speed of the crankshaft and an acceleration of the crankshaft based on the detected position of the crankshaft.
