A controller is configured to control an internal combustion engine. The internal combustion engine includes an intake passage, a motor, a forced-induction device, a flow rate adjusting valve, a crankcase, and first and second passages connected to the crankcase. The forced-induction device uses the motor to drive a compressor wheel provided in the intake passage. The flow rate adjusting valve is provided downstream of the compressor wheel in the intake passage. The controller includes processing circuitry configured to execute scavenging control that drives the motor with the flow rate adjusting valve closed in a case where engine shutdown is performed.

A filter abnormality determination system includes: an internal combustion engine having a plurality of cylinders; an exhaust passage connected to the internal combustion engine; a filter provided in the exhaust passage and opposed to the filter and outputting a detection value corresponding to an oxygen concentration in the exhaust gas; and a determination device, wherein the determination device includes a control unit that executes an imbalance control for controlling an air-fuel ratio of one of the plurality of cylinders to a value different from an air-fuel ratio of another of the plurality of cylinders; and a determination unit for determining whether the filter is abnormal based on a detection value of the sensor corresponding to an air-fuel ratio of an exhaust gas of the one cylinder during execution of the imbalance control.

Filter abnormality determination system

The inner surface of an oil passage in a member which is made as a die-cast formed product is made as a molded surface. By this structure, permeation of oil from the inner surface of the oil passage into the thickness portion of the member which is made as a die-cast formed product, and leakage thereof out to the exterior, is prevented.
