METHODS AND SYSTEMS FOR EGR SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17806310 titled 'METHODS AND SYSTEMS FOR EGR SYSTEM
Simplified Explanation
The patent application describes methods and systems for diagnosing an Exhaust Gas Recirculation (EGR) valve. The abstract specifically focuses on a method that compensates for the altitude of the vehicle by providing a correction to the position of the EGR valve. This correction is determined by comparing a pressure ratio to a curve rationalized with a barometric pressure.
- The method provides a correction to the position of the EGR valve based on the altitude of the vehicle.
- The correction is determined by comparing a pressure ratio to a curve rationalized with a barometric pressure.
- The method aims to improve the performance and efficiency of the EGR valve by compensating for altitude variations.
Potential Applications
This technology can be applied in various automotive systems and industries, including:
- Automotive manufacturing and assembly
- Engine design and development
- Emission control systems
- Vehicle maintenance and diagnostics
Problems Solved
The technology addresses several problems related to EGR valve performance and altitude variations, such as:
- Inaccurate EGR valve operation at different altitudes
- Reduced engine efficiency and performance due to altitude changes
- Difficulty in diagnosing and correcting EGR valve issues related to altitude variations
Benefits
The innovation offers several benefits to the automotive industry and vehicle owners, including:
- Improved accuracy and reliability of EGR valve operation
- Enhanced engine performance and efficiency across different altitudes
- Simplified diagnosis and correction of EGR valve issues related to altitude variations
- Potential reduction in emissions and environmental impact
Original Abstract Submitted
Methods and systems are provided for EGR valve diagnostic. In one example, a method includes providing a correction to a position of the EGR valve to compensate for an altitude of the vehicle. The compensation is based on a comparison of a pressure ratio to a curve rationalized with a barometric pressure.
