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 abstract describes a method for controlling the ignition timing of an engine based on intake air humidity and other factors. Here is a simplified explanation of the abstract:

• The engine control unit (ECU) measures the intake air humidity using a humidity sensor.
• Based on the intake air humidity and the exhaust gas recirculation (EGR) rate, the ECU calculates the amount of first ignition timing correction.
• The ECU also calculates the amount of second ignition timing correction based on the engine's operation region.
• The ECU then corrects the ignition timing of the engine using the calculated amounts of first and second ignition timing corrections.

Potential applications of this technology:

• Automotive industry: This method can be applied to control the ignition timing of engines in cars, trucks, and other vehicles.
• Power generation: The method can be used in engines used for power generation to optimize ignition timing based on intake air humidity and engine operation region.

Problems solved by this technology:

• Optimal ignition timing: By considering intake air humidity and engine operation region, this method helps in achieving the most efficient and effective ignition timing for the engine.
• Improved performance: Adjusting the ignition timing based on these factors can lead to improved engine performance, fuel efficiency, and reduced emissions.

Benefits of this technology:

• Enhanced efficiency: By accurately controlling the ignition timing, the engine can operate at its optimal performance level, resulting in improved fuel efficiency.
• Reduced emissions: Optimizing ignition timing based on intake air humidity and engine operation region can help in reducing harmful emissions from the engine.
• Improved engine performance: The method ensures that the engine operates with the correct ignition timing, leading to better overall performance and smoother operation.

Original Abstract Submitted

An engine ignition timing control method includes: acquiring, by an engine control unit (ECU), intake air humidity of an engine using a humidity sensor; calculating, by the ECU, an amount of first ignition timing correction based on the intake air humidity and an EGR rate; calculating, by the ECU, an amount of second ignition timing correction based on an engine operation region; and correcting, by the ECU, ignition timing of the engine using the amount of first ignition timing correction and the amount of second ignition timing correction.
