  • Patent number: 10663076
    Abstract: A rotation stop shape is visually recognizable through an exposing hole. A relative angle between an output shaft and an actuator lever can be freely set while the rotation stop shape, which is visually recognizable through the exposing hole, is used as the reference angle of the output shaft. Therefore, it is possible to limit disadvantageous variations in a fixation angle of the actuator lever. The fixation angle of the actuator lever relative to the output shaft can be freely changed by using the rotation stop shape, which is visually recognizable through the exposing hole, as a reference angle of the output shaft.

  • 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.

  • Patent number: 10655515
    Abstract: This blow-by gas recirculation device for an internal combustion engine is provided with a vacuum pump which supplies negative pressure to a brake booster and usable for recirculation of blow-by gas to an intake passage. This device includes: a PCV device for recirculating blow-by gas in a crankcase to the intake passage; a ventilation shortage region determination unit which determines whether or not an operational region of the engine is a PCV ventilation flow rate shortage region; and a brake negative pressure determination unit which determines whether or not the negative pressure of the brake booster is secured. The vacuum pump ventilates blow-by gas in the crankcase only when the determination units determines that the operational region is the PCV ventilation flow rate shortage region and that the negative pressure is secured. This reduces a contact risk of blow-by gas with engine oil, and inhibits the degradation of the oil.

  • Patent number: 10648403
    Abstract: In order for charge air to be conducted with the lowest possible losses in pressure in a turbocharger including a blow-off valve, a flow-guiding element in an inlet region is designed such that neutral zones are formed at the flow openings. The flow openings recirculate charge air from the pressure side to the suction side when the blow-off valve is opened. The flow-guiding element avoids vortices and therefore losses in pressure in the region of the flow openings.
