AIR SUPPLY DEVICE FOR AN ELECTRICALLY HEATED CATALYST AND A METHOD FOR CONTROLLING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17993125 titled 'AIR SUPPLY DEVICE FOR AN ELECTRICALLY HEATED CATALYST AND A METHOD FOR CONTROLLING THE SAME

Simplified Explanation

The patent application describes an air supply device for an electrically heated catalyst. The device includes an electronic supercharger, intake and exhaust valves, an electrically heated catalyst, and a controller.

  • The electronic supercharger is connected to the intake manifold and helps increase the air supply to the engine.
  • The intake valve is connected to the electronic supercharger and controls the flow of air into the engine.
  • The exhaust valve is connected to the exhaust manifold and controls the flow of exhaust gases out of the engine.
  • The electrically heated catalyst is connected to the exhaust manifold and is positioned in the front end of a catalyst part.
  • The controller is responsible for controlling the electronic supercharger, as well as the opening degree of the intake and exhaust valves.

The patent application explains that the controller controls the electronic supercharger based on a door opening condition during cold operation. It also switches the intake valve to an advance state and the exhaust valve to a retard state. This helps in heating the electrically heated catalyst.

Potential Applications

  • Automotive industry - The air supply device can be used in vehicles with electrically heated catalysts to improve their performance and reduce emissions.

Problems Solved

  • Cold start issues - The device helps in heating the electrically heated catalyst quickly during cold operation, improving the overall efficiency of the catalyst and reducing emissions.

Benefits

  • Improved catalyst performance - The device ensures that the electrically heated catalyst reaches its optimal operating temperature quickly, leading to better performance and reduced emissions.
  • Energy efficiency - The controller optimizes the operation of the electronic supercharger and valves, ensuring efficient use of energy.
  • Environmental benefits - By improving the performance of the electrically heated catalyst, the device helps in reducing harmful emissions from vehicles.


Original Abstract Submitted

An air supply device for an electrically heated catalyst is proposed. The device includes an electronic supercharger fluidly connected to an intake manifold, an intake valve fluidly connected to the electronic supercharger, an exhaust valve fluidly connected to an exhaust manifold of the engine, an electrically heated catalyst fluidly connected to the exhaust manifold and positioned in a front end of a catalyst part, and a controller configured to control driving of the electronic supercharger and an opening degree of each of the intake valve and the exhaust valve. The controller controls the electronic supercharger based on a door opening condition in a cold operation and switches the intake valve to an advance state and the exhaust valve to a retard state, thus heating the electrically heated catalyst.
