  • Patent number: 10711689
    Abstract: A control device is provided capable of reliably preventing occurrence of a surging state by judging a possibility of the surging state in a relatively easy manner and promptly executing a surging state avoidance control. When a supercharging pressure decreasing state in which a target supercharging pressure decreases is detected, an operating speed of a wastegate valve is determined based on a detected engine rotational speed. That is, by lowering the operating speed as the engine rotational speed lowers, reduction in flow rate of the air passing through a compressor is prevented, and the occurrence of the surging state is reliably prevented. By lowering the operating speed instead of changing a target opening degree of the wastegate valve, a maximum opening degree of the wastegate valve can be suppressed, and responsiveness in the case where an acceleration request is made immediately after deceleration of an engine can be improved.

  • Patent number: 10711714
    Abstract: The invention relates to a method for operating an internal combustion engine during any driving operation and in particular during a defined testing cycle which determines compliance with regulations. The internal combustion engine has at least one exhaust gas aftertreatment device with an adjustable degree of efficiency (for example by changing the reduction agent) or an exhaust gas recirculation device or alternative variables for changing the raw engine emissions. At least one monitoring window is assigned to the active profile. The aim of the invention is to allow strict exhaust gas regulations to be met in particular during real driving operations while simultaneously allowing a low fuel consumption. This is achieved in that at least one main monitoring window of the driving profile and a sub-monitoring window (F2) with a starting point and an end point are defined within a driving profile or test cycle.

  • Patent number: 10690067
    Abstract: When a waste gate valve (7) is forcibly fully closed for learning control at the time of start, the drive force of an electric actuator (20) is initially set to a large first level, and when a predetermined position (L1) immediately before seating is reached, the driving force is reduced to a second level. As a result, a valve body (7a) is gently seated. When a predetermined time (TM1) passes, the driving force is increased to a third level. Consequently, the electric actuator (20) presses the valve body (7a) onto a seat surface (34a) while displacing a spring member (37). As a result, a reliable sealability is obtained.

  • Patent number: 10663426
    Abstract: A sensor controller includes a signal reception determination section and a use suspension section. The signal reception determination section determines whether or not the sensor controller has received a specific state signal that indicates a specific state in which exhaust gas may contain a specific gas that differs from ammonia and reacts with an ammonia sensor. When the signal reception determination section determines that the sensor controller has received the specific state signal, the use suspension section suspends at least temporarily use of a detection result detected by the ammonia sensor after the determination. Specifically, upon reception of the specific state signal, the sensor controller suspends at least temporarily the use of the detection result detected by the ammonia sensor after the reception of the specific state signal.
