Introduction

Katsuyoshi Koyanagi is a notable inventor based in Esslingen, Germany. He has made significant contributions to the field of internal combustion engines, holding 2 patents that showcase his innovative approaches to engine operation and evaluation.

Latest Patents

One of Koyanagi's latest patents is a method of operating a diesel internal combustion engine. This method involves forming a homogeneous mixture in the combustion space before spontaneous ignition. Fuel is injected directly into separately supplied combustion air, which is admitted in a swirling flow that can be adjusted for swirl intensity. A control unit coordinates the swirl intensity with injection parameters to ensure effective engine operation with low emissions.

Another significant patent is a method for evaluating an ion current signal of a self-igniting internal combustion engine. This method derives the ignition shift from the time shift of the local maximum in the ion current signal curve relative to the injection point. It allows for the detection of continuous injection in a cylinder and can control injection parameters based on the evaluation of the ion current signal.
