Title: **Innovator Kenji Nakajima: Pioneering Patents in Engine Control Technology**

Introduction

Kenji Nakajima, an esteemed inventor based in Chiyoda-ku, Japan, has made significant contributions to the field of engine control technology. With a remarkable portfolio of 14 patents, his innovations continue to shape the landscape of automotive engineering and energy conversion systems.

Latest Patents

Among Nakajima's latest patents is the **Internal-combustion-engine control apparatus**. This advanced technology features an intake-air-temperature correction control apparatus that includes a first-order advance compensation means. This system calculates an advance-compensation amount for an intake-air temperature detection signal. It is equipped with a time constant determination means that assesses a time constant for the first-order advance compensation and a first-order delay compensation means, ensuring an efficient operation of the engine. Furthermore, it includes a time constant setting means, an upper-limit-value setting means, and a minimum value selection means to optimize response based on varying intake-air flow rates.

Another notable patent is the **Power converter and control method for power converter**. In this invention, a control section is designed to manage voltage levels effectively. When a voltage of a B-terminal of a power generator exceeds a predetermined threshold, the control section activates all switching elements of a negative arm in a bridge circuit while deactivating those of the positive arm. This innovative approach helps in reducing the field current in a field winding, ensuring smooth operation and stability in power conversion processes.
