An exhaust system includes a supercharger, a first communication path, a negative pressure generator, and an exhaust sensor. The supercharger includes a turbine and compressor. The turbine is provided in an exhaust pipe of an engine. The compressor is provided in an intake pipe and coupled to the turbine by a shaft. The supercharger supercharges intake air using energy of exhaust air. The first communication path communicates with the exhaust pipe on a downstream side of the turbine and communicates with the intake pipe on an upstream side of the compressor. The exhaust pipe and the intake pipe communicate through the first communication path. The negative pressure generator is interposed in the first communication path and generates a negative pressure. The exhaust sensor is provided in the first communication path between a location where the first communication path is coupled to the exhaust pipe and the negative pressure generator.

Exhaust system

A vehicle cooling system includes a circulation flow path section which has a first flow path section and a second flow path section, and a solenoid valve which can switch between an open state in which the first flow path section and the second flow path section are connected and a closed state in which the first flow path section and the second flow path section are blocked. The circulation flow path section includes a valve body accommodating section configured to include a first accommodating section and a second accommodating section which connects the first flow path section and the second flow path section in the open state, and a connection flow path section whose one end is connected to the first flow path section. The other end of the connection flow path section opens to the first accommodating section.

A blow-by gas supply device includes an upstream-side passage, a downstream-side passage, a gas passage, a bypass passage, a valve mechanism, and a valve control unit. The device is provided in an engine including a compressor, and recirculates blow-by gas upstream of the compressor. The upstream-side passage is coupled to an input port of the compressor. The downstream-side passage is coupled to an output port of the compressor. The gas passage is coupled to the upstream-side passage and guides the blow-by gas from inside of the engine to the upstream-side passage. The bypass passage is coupled to the upstream-side passage and the downstream-side passage and guides the intake air from the downstream side passage to the upstream side passage. The valve mechanism is provided in the bypass passage and switched between communication and cutoff states. The valve control unit controls the valve mechanism in the communication or cutoff state.
