ENGINE IGNITION TIMING CONTROL METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17696246 titled 'ENGINE IGNITION TIMING CONTROL METHOD
Simplified Explanation
The patent application describes a method for controlling the ignition timing of an engine based on intake air humidity and engine operation region. The engine control unit (ECU) acquires the intake air humidity using a humidity sensor and calculates the first ignition timing correction based on the intake air humidity and an EGR rate. It also calculates the second ignition timing correction based on the engine operation region. The ECU then corrects the ignition timing of the engine using these calculated corrections.
- The engine control unit (ECU) acquires intake air humidity using a humidity sensor.
- The ECU calculates the first ignition timing correction based on the intake air humidity and an EGR rate.
- The ECU calculates the second ignition timing correction based on the engine operation region.
- The ECU corrects the ignition timing of the engine using the calculated first and second ignition timing corrections.
Potential Applications
- Automotive industry: This technology can be applied in the development of advanced engine control systems for automobiles.
- Engine manufacturing: Engine manufacturers can incorporate this technology to improve the performance and efficiency of their engines.
Problems Solved
- Inaccurate ignition timing: By considering intake air humidity and engine operation region, this technology helps in accurately controlling the ignition timing of an engine, leading to improved performance and efficiency.
