MISFIRE DETERMINATION APPARATUS FOR INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240110848 titled 'MISFIRE DETERMINATION APPARATUS FOR INTERNAL COMBUSTION ENGINE
Simplified Explanation
The patent application describes a misfire determination apparatus for an internal combustion engine that can detect single-cylinder or multi-cylinder misfires based on the rotational speed of the engine.
- The apparatus includes a rotational speed detector and a microprocessor.
- The microprocessor calculates a misfire parameter based on the change in rotational speed during the combustion stroke of each cylinder.
- It determines a single-cylinder misfire if the misfire parameter is below a first predetermined value, and a multi-cylinder misfire if it is below a second predetermined value greater than the first.
Potential Applications
This technology can be used in automotive engines to accurately detect misfires and improve engine performance.
Problems Solved
1. Efficient detection of misfires in internal combustion engines. 2. Enhancing engine reliability and performance by identifying misfires promptly.
Benefits
1. Improved engine efficiency and fuel consumption. 2. Reduced emissions and environmental impact. 3. Enhanced engine longevity and reliability.
Potential Commercial Applications
Optimizing engine performance in automotive vehicles for better fuel efficiency and reduced maintenance costs.
Possible Prior Art
One possible prior art is the use of individual cylinder pressure sensors to detect misfires in internal combustion engines.
What is the accuracy of misfire detection using this apparatus?
The accuracy of misfire detection using this apparatus is high due to the precise calculation of the misfire parameter based on the change in rotational speed during the combustion stroke of each cylinder.
How does this technology compare to traditional misfire detection methods?
This technology offers a more advanced and reliable method of misfire detection compared to traditional methods, as it can differentiate between single-cylinder and multi-cylinder misfires based on the calculated misfire parameter.
Original Abstract Submitted
a misfire determination apparatus for an internal combustion engine including a rotational speed detector detecting a rotational speed of an engine and a microprocessor. the microprocessor is configured to perform calculating a misfire parameter having a correlation with a change amount of the rotational speed in a combustion stroke of each of a plurality of cylinders and increasing as an increase amount of the rotational speed is large based on the rotational speed detected by the rotational speed detector, and determining that a single-cylinder misfire has occurred when the misfire parameter is less than a first predetermined value, while determining that the single-cylinder misfire or a multi-cylinder misfire has occurred when the misfire parameter is less than a second predetermined value greater than the first predetermined value.
