Title: Youhei Hosokawa: Innovator in Internal Combustion Engine Technology

Introduction

Youhei Hosokawa is a notable inventor based in Susono, Japan. He has made significant contributions to the field of internal combustion engine technology, holding a total of 3 patents. His work focuses on enhancing engine performance and efficiency through innovative methods and devices.

Latest Patents

One of Hosokawa's latest patents is a "Device and method for controlling internal combustion engine." This invention provides a mechanism for injecting a prescribed amount of fuel over a predetermined period until an air-fuel ratio sensor is activated. This process is crucial when fuel cut control of the internal combustion engine is stopped to resume normal engine operation. Additionally, if EGR gas is inducted immediately before the fuel cut control starts, the prescribed amount of fuel is reduced.

Another significant patent is for a "Multicylinder engine and method for controlling the same." In this invention, Hosokawa addresses the challenges faced during cylinder deactivation modes, such as the virtual V-four operation mode. This mode involves deactivating two cylinders of a V-six engine, which can lead to uneven ignition and combustion intervals in the operating cylinders. To mitigate this issue, the multicylinder engine includes an ignition timing adjustment unit that smooths the output torque by adjusting the ignition timing in each of the operating cylinders.
