CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18327206 titled 'CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE
Simplified Explanation
The patent application describes a control apparatus for an internal combustion engine that detects misfires in each combustion stroke of the engine's cylinders. It counts the number of times a single misfire occurs for each cylinder and determines if a misfire is happening in a specific cylinder. If a misfire is detected, the apparatus corrects the ignition timing of that cylinder to an advance angle side.
- The control apparatus detects misfires in an internal combustion engine.
- It counts the number of times a single misfire occurs for each cylinder.

Original Abstract Submitted
A control apparatus, for an internal combustion engine, detects a rotational speed parameter (time parameter) that represents a rotational speed of the internal combustion engine including a plurality of cylinders, detects a single misfire that is a misfire for every ignition for each of the plurality of cylinders, based on the rotational speed parameter that has been detected in each combustion stroke of the plurality of cylinders (steps to and ), counts, as a misfire counter value, the number of times that the single misfire has been detected for each of the plurality of cylinders (steps and ), determines whether the misfire is occurring in the cylinder, based on the misfire counter value (steps to ), and corrects an ignition timing of the cylinder that has been determined that the misfire is occurring to an advance angle side (steps , and ).
