EXHAUST GAS CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18125191 titled 'EXHAUST GAS CONTROL APPARATUS OF INTERNAL COMBUSTION ENGINE
Simplified Explanation
The abstract describes an exhaust gas control apparatus for an internal combustion engine that includes an exhaust gas control catalyst, an electrochemical reactor, and a control device.
- The exhaust gas control catalyst is placed in the exhaust gas passage of the engine and can purify a specific component in the exhaust gas.
- The electrochemical reactor is located downstream of the exhaust gas control catalyst and is activated to purify the target component in the exhaust gas.
- The control device regulates the activation of the electrochemical reactor based on the active state of the exhaust gas control catalyst and the air-fuel ratio of the incoming exhaust gas.
Potential applications of this technology:
- Automotive industry: This technology can be used in vehicles to effectively control and reduce harmful emissions from internal combustion engines.
- Environmental regulations: The exhaust gas control apparatus can help meet and comply with strict emission standards set by environmental regulations.
Problems solved by this technology:
- Emission reduction: The apparatus addresses the problem of reducing harmful emissions from internal combustion engines, contributing to cleaner air and improved environmental conditions.
- Catalyst efficiency: By monitoring the active state of the exhaust gas control catalyst and adjusting the activation of the electrochemical reactor, the apparatus ensures optimal performance and longevity of the catalyst.
Benefits of this technology:
- Improved air quality: The apparatus helps in purifying exhaust gases, reducing the release of pollutants into the atmosphere, and improving overall air quality.
- Compliance with regulations: By effectively controlling emissions, the technology enables compliance with environmental regulations and standards.
- Enhanced catalyst performance: The control device ensures that the exhaust gas control catalyst operates at its best, maximizing its efficiency and lifespan.
Original Abstract Submitted
An exhaust gas control apparatus for an internal combustion engine for purifying exhaust gas discharged from an engine main body includes an exhaust gas control catalyst disposed in an exhaust gas passage of an internal combustion engine and capable of purifying a target component in the exhaust gas, an electrochemical reactor disposed in the exhaust gas passage on a downstream side in an exhaust flow direction of the exhaust gas control catalyst, and a control device for controlling energization of the electrochemical reactor. The electrochemical reactor is configured to purify the target component in the exhaust gas when energized. The control device controls the energization of the electrochemical reactor on the basis of an active parameter indicating an active state of the exhaust gas control catalyst and an air-fuel ratio parameter related to an air-fuel ratio of the inflow exhaust gas flowing into the electrochemical reactor.
