Title: Yuichi Kohara: Innovator in Internal Combustion Engine Technology
Introduction
Yuichi Kohara is a prominent inventor based in Toyota, Japan. He has made significant contributions to the field of internal combustion engine technology, holding a total of six patents. His work focuses on improving the efficiency and performance of multi-cylinder internal combustion engines.
Latest Patents
Kohara's latest patents include an "Apparatus for detecting imbalance abnormality in air-fuel ratio between cylinders in multi-cylinder internal combustion engine." This innovative apparatus increases the fuel injection quantity to a predetermined target cylinder to detect imbalance abnormalities in the air-fuel ratio. The detection process is based on the rotation variation of the target cylinder after the fuel injection quantity is increased. This method is executed during the post-fuel-cut rich control, minimizing exhaust emission deterioration during abnormality detection.
Another notable patent is the "Abnormality detection apparatus and abnormality detection method for multi-cylinder internal combustion engine." This apparatus changes the fuel injection quantity of a predetermined target cylinder to detect abnormalities in the engine. It utilizes values of rotational variations detected before and after the change in fuel injection quantity, correcting these values based on engine revolutions and load at the corresponding detection time.
