  • Patent number: 11326540
    Abstract: An abnormality determination device of an internal combustion engine in which a breather line connects an intake-air path positioned upstream from a forced-induction system and a crankcase includes an intake-air flow rate sensor that detects an intake air flow rate in the intake-air path, a pressure sensor that detects a pressure of the breather line, and an abnormality determination unit that determines abnormality of the breather line. The abnormality determination unit estimates an intake air resistance of the intake-air path from the pressure when the engine is under low load conditions under which the intake air flow rate is less than a predetermined value and the pressure when the engine is under high load conditions under which the intake air flow rate is the predetermined value or greater and determines abnormality of the breather line when the intake air resistance is less than a threshold.

  • Patent number: 11293367
    Abstract: In a failure determination device for an internal combustion engine equipped with a supercharger, the failure determination device determining a failure of a breather pipe that is connected between a crankcase and an intake passage at a position on an upstream side of the supercharger, the breather pipe is constituted by a double pipe including an inner pipe and an outer pipe, a communication passage communicates an enclosed space between the inner pipe and the outer pipe of the breather pipe with a portion of the intake passage on a downstream side of the supercharger. When the detected breather outer-pipe gauge pressure is higher than or equal to a determination threshold that is set in accordance with detected intake gauge pressure, the failure determination device determines that the breather pipe is failed.

  • Patent number: 11174765
    Abstract: An abnormality assessment device includes an on-off valve that shuts an intake path on an upstream side of a connection portion of a breather line with respect to the intake path and an abnormality assessment element that assesses abnormality of the breather line. The abnormality assessment element assesses abnormality of the breather line based on a difference between an intake flow rate that is detected by an intake flow rate sensor and a target intake flow rate in a case where the on-off valve is closed.
