Akira Watabe

Title: Akira Watabe and Engine Air-Control Innovations.

Introduction

Akira Watabe is an inventor associated with Fujimi, Japan, and Honda Giken Kogyo Kabushiki Kaisha, commonly known as Honda Motor Co., Ltd. Watabe’s patent work addresses secondary-air control systems for internal-combustion engines. The supplied information lists 2 patents.

Latest Patents

Watabe’s listed patents concern an air-intake-side secondary-air supply system for an internal-combustion engine.

One patent describes separate secondary-air passages controlled by an open/close valve and an air-control valve. Its pressure-control device rapidly supplies a closing pressure when the engine transitions from feedback control to open-loop control, with the aim of improving driveability during that transition.

The other patent describes a system that rapidly closes a secondary-air passage when a no-load condition is detected during cold engine operation. This action stops at least the integral component of air/fuel-ratio feedback control, with the aim of improving engine operation when the engine is cold and unloaded.

Career Highlights

Watabe’s listed inventions focus on coordinating secondary-air flow with engine operating conditions. The patent descriptions emphasize responsive valve control during changes in feedback mode and during cold, no-load operation.

Collaborations

The supplied information identifies Norio Suzuki and Kazunari Yamashita as Watabe’s coworkers. It does not specify their roles or the details of any joint work.

Conclusion

Akira Watabe’s listed patents reflect engineering work on secondary-air systems designed to support engine control and driveability under changing operating conditions.
