Title: **The Innovative Contributions of Kei Murakami**

Introduction

Kei Murakami, an accomplished inventor based in Zama, Japan, has made significant strides in the field of internal combustion engine technology. With a total of six patents to his name, his innovations focus on enhancing engine performance and reducing vibrations linked to abnormal combustion.

Latest Patents

Murakami's latest patents revolve around two groundbreaking systems: the abnormal combustion detection and vibration reduction system. This apparatus and method are designed to detect abnormal combustion in an internal combustion engine while also controlling the vibrations caused by such occurrences. Key components of the detection apparatus include:

- A unit for detecting the rotation of the internal combustion engine.

- A unit for calculating the rotation angular acceleration based on the detected rotation.

- A comparison unit that analyzes the calculated angular acceleration against a predetermined reference value.

By assessing these parameters, the system can accurately determine the occurrence of abnormal combustion. To tackle vibration issues, Murakami's vibration reduction system cleverly offsets vibrations by passing a pulse-like field current through an electric generator, generating torque that mitigates vibration from both the generator and the combustion engine.

Another notable invention is the apparatus for reducing vibrations in vehicle bodies. This mechanism effectively induces vibrations in a generator, which helps to diminish vibrations arising from engine irregularities. By adjusting the load torque of the generator during rough idling conditions, the system can achieve a cancellation of engine and body vibrations, ensuring a smoother driving experience.
