Title: The Innovations of Osamu Fukasawa

Introduction

Osamu Fukasawa is a notable inventor based in Nagoya, Japan. He has made significant contributions to the field of engine technology, holding a total of nine patents. His work primarily focuses on fuel injection systems, which are crucial for enhancing engine performance and efficiency.

Latest Patents

Fukasawa's latest patents include a fuel injection control device for engines and a controller for direct injection engines. The fuel injection control device executes a split injection, consisting of a fixed injection and a variable injection. The required injection amount for the fixed injection is set in a low range, while the variable injection is set in a high range. The variable injection amount can be adjusted within the high range based on engine load variations. This innovative approach allows for improved control of the air-fuel ratio, enhancing engine performance.

The controller for direct injection engines features an ECU that feedback controls the discharge amount of a high-pressure pump. This ensures that the detected fuel pressure aligns with a target fuel pressure. The ECU also determines when engine shutdown is imminent, adjusting the target fuel pressure to prevent fuel leakage from the injector during shutdown conditions.
