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 abstract 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 controller controls the electronic supercharger and the opening degree of the valves to heat the catalyst.
- The device includes an electronic supercharger that is connected to an intake manifold.
- The intake valve is connected to the electronic supercharger, while the exhaust valve is connected to the exhaust manifold of the engine.
- An electrically heated catalyst is connected to the exhaust manifold and positioned in the front end of a catalyst part.
- The controller is responsible for controlling the electronic supercharger and the opening degree of the intake and exhaust valves.
- In cold operation, the controller controls the electronic supercharger based on a door opening condition.
- The controller switches the intake valve to an advance state and the exhaust valve to a retard state, which helps in heating the electrically heated catalyst.
Potential Applications
- Automotive industry
- Emission control systems
Problems Solved
- Efficiently heating the electrically heated catalyst in cold operation
Benefits
- Improved performance of the electrically heated catalyst
- Enhanced emission control system efficiency
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.
