ANOMALY DETERMINATION DEVICE FOR INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18589315 titled 'ANOMALY DETERMINATION DEVICE FOR INTERNAL COMBUSTION ENGINE

Simplified Explanation: The patent application describes a process where an Engine Control Unit (ECU) temporarily stops fuel injection in an internal combustion engine by executing a fuel cut-off time ignition process. The ECU detects if the fuel injection valve is stuck open by monitoring rotation fluctuations during this process.

The ECU executes a fuel cut-off time ignition process to temporarily stop fuel injection.
The ignition device generates a spark discharge during the fuel cut-off.
The ECU detects if the fuel injection valve is stuck open by analyzing rotation fluctuations.
If the rotation fluctuation amount exceeds a predetermined value, the ECU determines that the valve is stuck open.
This innovation helps prevent issues with fuel injection valves getting stuck open, improving engine performance and efficiency.

Potential Applications: This technology can be applied in automotive engines, motorcycles, and other internal combustion engine systems where precise control of fuel injection is crucial.

Problems Solved: 1. Prevents fuel injection valve from getting stuck open. 2. Improves engine performance by ensuring proper fuel injection timing. 3. Enhances fuel efficiency by optimizing fuel delivery.

Benefits: 1. Increased engine reliability. 2. Improved fuel efficiency. 3. Enhanced engine performance. 4. Reduced maintenance costs.

Commercial Applications: Title: Advanced Fuel Injection Control System for Internal Combustion Engines This technology can be utilized by automotive manufacturers, engine tuning companies, and aftermarket performance parts suppliers to enhance engine performance and efficiency.

Prior Art: Prior research in the field of engine control systems and fuel injection technology may provide insights into similar methods of detecting and preventing fuel injection valve issues.

Frequently Updated Research: Researchers are constantly exploring new ways to optimize fuel injection systems in internal combustion engines for better performance and efficiency.

Questions about Fuel Injection Valve Control: 1. How does the ECU determine if the fuel injection valve is stuck open? The ECU monitors rotation fluctuations during the fuel cut-off time ignition process to detect if the valve is stuck open.

2. What are the potential implications of a stuck-open fuel injection valve on engine performance? A stuck-open fuel injection valve can lead to inefficient fuel delivery, poor engine performance, and increased fuel consumption.

Original Abstract Submitted

An ECU executes a fuel cut-off time ignition process that causes the ignition device to generate a spark discharge during a fuel cut-off for temporarily stopping fuel injection of the fuel injection valve. The ECU determines that the fuel injection valve is stuck open when a rotation fluctuation amount of an internal combustion engine during execution of the fuel cut-off time ignition process is greater than or equal to a predetermined stuck-open determination value.
