METHOD FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE INCLUDING AT LEAST ONE EXHAUST-GAS AFTERTREATMENT COMPONENT HAVING AN ELECTRIC HEATING ELEMENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18355334 titled 'METHOD FOR CONTROLLING AN INTERNAL COMBUSTION ENGINE INCLUDING AT LEAST ONE EXHAUST-GAS AFTERTREATMENT COMPONENT HAVING AN ELECTRIC HEATING ELEMENT
Simplified Explanation
The abstract describes a method for controlling an internal combustion engine with an exhaust-gas aftertreatment component that has an electric heating element. The heating element heats the exhaust-gas aftertreatment component, and the exhaust gas flows through it. The heating element is acted upon by a heating current and a gas (such as fresh air or exhaust gas) flowing downstream through the exhaust-gas path. The method involves measuring the temperature upstream from the exhaust-gas aftertreatment component.
- The patent application describes a method for controlling an internal combustion engine with an exhaust-gas aftertreatment component.
- The exhaust-gas aftertreatment component has an electric heating element that heats it.
- The heating element is briefly or permanently acted upon by a heating current and a gas flowing downstream through the exhaust-gas path.
- The method involves measuring the temperature upstream from the exhaust-gas aftertreatment component.
Potential applications of this technology:
- Automotive industry: This method can be applied to control internal combustion engines in vehicles, ensuring efficient operation of the exhaust-gas aftertreatment component.
- Emission control systems: The method can be used in exhaust-gas aftertreatment systems to improve the performance of emission control devices, such as catalytic converters.
Problems solved by this technology:
- Efficient heating: The method ensures effective heating of the exhaust-gas aftertreatment component, which is crucial for its optimal performance.
- Temperature control: By measuring the temperature upstream from the aftertreatment component, the method allows for precise control of the heating element, preventing overheating or underheating.
Benefits of this technology:
- Improved emission control: The method ensures that the exhaust-gas aftertreatment component is properly heated, leading to more efficient removal of pollutants from the exhaust gas.
- Enhanced engine performance: By controlling the temperature of the aftertreatment component, the method helps optimize the overall performance of the internal combustion engine.
- Energy efficiency: The method allows for the heating element to be activated only when necessary, reducing energy consumption and improving fuel efficiency.
Original Abstract Submitted
A method for controlling an internal combustion engine including at least one exhaust-gas aftertreatment component having an electric heating element, the electric heating element heating the exhaust-gas aftertreatment component and the exhaust gas flowing through the exhaust-gas aftertreatment component, the electric heating element briefly or permanently being acted upon by a heating current, a gas, in particular fresh air and/or exhaust gas, flowing downstream through the exhaust-gas path. In the method, a first temperature upstream from the at least one exhaust-gas aftertreatment component is ascertained,
