Apparatus and Method for Reducing Fouling of Exhaust Gas Recirculation Cooler - A simplified explanation of the abstract
This abstract first appeared for US patent application 17970809 titled 'Apparatus and Method for Reducing Fouling of Exhaust Gas Recirculation Cooler
Simplified Explanation
The embodiment apparatus described in the patent application aims to reduce fouling of an exhaust gas recirculation (EGR) cooler in an exhaust gas post-treatment system. The system includes a diesel oxidation catalyst (DOC), an exhaust line, an EGR cooler, and an EGR line.
- The apparatus includes an exhaust gas transfer part that connects the DOC to the EGR cooler.
- A valve is installed in the exhaust gas transfer part to control the flow of exhaust gas.
- A controller is provided to selectively open the valve when the exhaust gas post-treatment system enters a predetermined diesel particulate filter (DPF) regeneration condition.
- When the valve is open, exhaust gas discharged from the DOC is supplied to the EGR cooler through the exhaust gas transfer part.
Potential applications of this technology:
- Automotive industry: This apparatus can be used in diesel engines to reduce fouling of EGR coolers, improving engine performance and reducing emissions.
- Exhaust gas post-treatment systems: The apparatus can be integrated into various exhaust gas post-treatment systems to enhance their efficiency and reliability.
Problems solved by this technology:
- Fouling of EGR coolers: The apparatus helps to reduce fouling of EGR coolers by selectively supplying exhaust gas from the DOC to the cooler during DPF regeneration conditions.
- Engine performance degradation: By preventing fouling of the EGR cooler, the apparatus ensures optimal performance of the engine and exhaust gas post-treatment system.
Benefits of this technology:
- Improved engine performance: By reducing fouling of the EGR cooler, the apparatus helps maintain the efficiency and performance of the engine.
- Reduced emissions: The apparatus contributes to lower emissions by preventing fouling and ensuring proper functioning of the exhaust gas post-treatment system.
- Enhanced system reliability: By selectively supplying exhaust gas to the EGR cooler during DPF regeneration conditions, the apparatus improves the reliability and longevity of the exhaust gas post-treatment system.
Original Abstract Submitted
An embodiment apparatus for reducing fouling of an exhaust gas recirculation (EGR) cooler includes an exhaust gas transfer part configured to connect a diesel oxidation catalyst (DOC) of an exhaust gas post-treatment system extending from an engine through an exhaust line to an EGR cooler installed in an EGR line and configured to recirculate exhaust gas discharged from an exhaust manifold to an intake manifold, a valve installed in the exhaust gas transfer part, and a controller configured to selectively open the valve as the exhaust gas post-treatment system enters a predetermined diesel particulate filter (DPF) regeneration condition and allow exhaust gas discharged from the DOC to be supplied to the EGR cooler through the exhaust gas transfer part.
