摘要:
Methods and systems for controlling an engine that may be automatically stopped and started are presented. In one example, a compressor is activated from a deactivated state in response to one or more environmental parameters during an engine start. The methods and systems may improve engine response after an engine start.
摘要:
A method for controlling a propulsion system for a vehicle including a transmission coupling an output shaft of the internal combustion engine to a drive wheel of the vehicle, wherein said transmission includes a lash region, the method comprising of adjusting an operating parameter of the engine so that at least one cylinder of the engine is transitioned between a first combustion mode and a second combustion mode, and varying a timing of said transition responsive to whether the transmission is operating within the lash region of the transmission.
摘要:
A method for controlling a vehicle operation in the transmission lash region. One method includes transitioning a combustion mode of a cylinder, and varying a timing of said transition responsive to whether the transmission is operating within the lash region of the transmission.
摘要:
Systems and methods for controlling shut down of a multiple cylinder internal combustion engine include a mechanical energy storage device to decelerate an engine crankshaft to a stopping position desirable for restarting of the engine. Energy stored during shut down may be used to adjust or reposition the crankshaft to one of a plurality of angular orientations advantageous for restarting, and/or used to rotate the crankshaft during restarting of the engine. A flywheel having a variable mass, such as provided by two or more segments, which may be fixedly or selectively coupled to one or more springs may be used to selectively store and release energy.

摘要:
Embodiments for operating an engine with direct injection are provided. In one example, a method for operating an applied-ignition internal combustion engine having at least one cylinder and direct injection comprises raising a component temperature of an injection device of the at least one cylinder at least locally in a region of a catalytic coating in order to initiate and assist oxidation of coking residues. Thus, deposits of coking residues may be counteracted even in part-load operation.
