摘要： Methods and systems that monitor an actuator state of wear. One or more observations are made as to one or more extremum positions of the actuator to determine a reference extremum position when the actuator is not worn. As the actuator becomes worn, the difference between a present extremum position and the reference is used to monitor actuator wear. Actuator wear may be observed to identify or predict a need for maintenance or replacement, and/or may be used in determining health impacts of control system solutions.

摘要： During execution of a purge, a purge concentration-related value is learned based on an air-fuel ratio deviation that is a deviation of an air-fuel ratio detected by an air-fuel ratio sensor from a required air-fuel ratio. In this case, the purge concentration-related value is updated using an update amount with a smaller absolute value when the purge is a second purge of supplying evaporated fuel gas to an intake pipe through a second purge passage than when the purge is a first purge of supplying the evaporated fuel gas to the intake pipe through a first purge passage.

摘要： Methods and systems are provided for a pre-chamber ignition system. In one example, a pre-chamber ignition system may include a pre-chamber extending into a combustion chamber, a piston protrusion shaped to fit through a bottom aperture of the pre-chamber, and a plurality of orifices formed by sidewall of the pre-chamber. A method for the pre-chamber ignition system includes adjusting spark timing within the pre-chamber and pressing the protrusion into the pre-chamber to ignite air/fuel within a main chamber.

摘要： An engine includes: a turbocharger including a turbine and a compressor; an EGR passage connecting an exhaust passage on an upstream side of the turbine and an air intake passage on a downstream side of the compressor; an EGR valve provided in the EGR passage; a bypass passage that bypasses the turbine; and a waste gate valve provided in the bypass passage. In the engine, when a boost pressure is increased to a limit pressure, a first boost pressure control is executed, in which the EGR valve is opened and the waste gate valve is closed. After the first boost pressure control starts, when an engine speed is increased to a prescribed value, a second boost pressure control is executed, in which the waste gate valve is opened in addition to the EGR valve.

摘要： A hybrid vehicle includes an engine, an exhaust gas recirculation device, a traveling motor, and a control device. The exhaust gas recirculation device includes a communication pipe that allows an exhaust pipe and an intake pipe of the engine to communicate with each other and a valve that is provided in the communication pipe. The control device is configured to perform foreign matter removal control for opening and closing the valve when foreign matter caught in the valve is detected and the hybrid vehicle stops.
