Abstract
An exhaust gas processing system includes a cylindrical tube through which an exhaust gas of an engine passes, a sensor configured to detect information regarding the exhaust gas discharged from the engine, a coil antenna provided on an outer periphery of the cylindrical tube and connected to a high-frequency power supply, and a control unit configured to control output power of the high-frequency power supply. The control unit controls output power of the high-frequency power supply based on the information detected by the sensor.
Claims16
An exhaust gas processing device, comprising:
- a cylindrical tube through which an exhaust gas discharged from an engine passes;
- and
- a coil antenna provided on an outer periphery of the cylindrical tube and connected to a high-frequency power supply.
An exhaust gas processing system, comprising:
- a cylindrical tube through which an exhaust gas discharged from an engine passes;
- a high-frequency power supply;
- a coil antenna provided on an outer periphery of the cylindrical tube and connected to the high-frequency power supply;
- a sensor configured to detect information regarding the exhaust gas discharged from the engine;
- and
- a control unit configured to control an output power of the high-frequency power supply based on the detected information.
A method for controlling an exhaust gas processing system which includes a cylindrical tube through which an exhaust gas discharged from an engine passes, a high-frequency power supply, a coil antenna provided on an outer periphery of the cylindrical tube and connected to the high-frequency power supply, a sensor configured to detect information regarding the exhaust gas discharged from the engine, and a control unit, the method comprising:
- detecting the information regarding the exhaust gas discharged from the engine with the sensor;
- and
- controlling an output power of the high-frequency power supply based on the detected information by the control unit.
A control program for an exhaust gas processing system which includes a cylindrical tube through which an exhaust gas discharged from an engine passes, a high-frequency power supply, a coil antenna provided on an outer periphery of the cylindrical tube and connected to the high-frequency power supply, a sensor configured to detect information regarding the exhaust gas discharged from the engine, and a control unit, wherein the control program executes:
- detecting the information regarding the exhaust gas discharged from the engine with the sensor;
- and
- controlling an output power of the high-frequency power supply based on the detected information by the control unit.
A cylindrical tube around which a coil antenna is wound, the cylindrical tube comprising:
- an exhaust gas path through which an exhaust gas of an engine passes;
- and
- a coolant flow path provided at an outer periphery of the exhaust gas path.
