Abstract
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.
Claims5
A controller for an internal combustion engine, wherein
- the internal combustion engine includes:
- an intake passage;
- a compressor wheel provided in the intake passage;
- a motor;
- a forced-induction device that drives the compressor wheel using the motor;
- a flow rate adjusting valve provided downstream of the compressor wheel in the intake passage;
- a crankcase;
- a first passage that fluidly connects the crankcase to the intake passage between the compressor wheel and the flow rate adjusting valve;
- and
- a second passage that fluidly connects the crankcase to a section of the
- intake passage on a downstream side of the flow rate adjusting valve, and the controller comprises processing circuitry configured to execute scavenging control that drives the motor with the flow rate adjusting valve closed in a case where shutdown of the engine is performed.
