Title: **Kenji Kawahara: Innovator in Engine Control Technologies**

Introduction

Kenji Kawahara, an esteemed inventor hailing from Kariya, Japan, has made significant contributions to the automotive industry, particularly in the field of engine control technology. With a remarkable portfolio of 14 patents, Kawahara has demonstrated his expertise and commitment to advancing vehicle efficiency and safety.

Latest Patents

Among his latest innovations is an engine control apparatus designed to perform automatic engine restart, aimed at ensuring brake booster assistance after an automatic engine stop. This technology is particularly beneficial for vehicles equipped with a vacuum-assist type of brake booster that relies on the engine's intake air pressure. The device automatically stops the engine under specific conditions and restarts it when it detects a drop in brake booster pressure below a certain level. It further ensures engine reactivation if a designated maximum time interval has passed since the engine was halted, thus preventing excessive drop in booster pressure.

Another notable patent is the control apparatus for the automatic stop of an engine. This invention regulates the engine's automatic shutdown based on predetermined conditions, such as the vehicle's running speed. The apparatus incorporates a prediction unit that forecasts whether the next automatic stop will occur within a timeframe that still affords fuel-saving benefits, using historical data of the vehicle's stop times. If the prediction indicates that stopping the engine won’t yield a fuel-saving advantage, the system will prohibit the automatic stop.

Career Highlights

Kenji's illustrious career includes tenures at leading automotive companies such as Denso Corporation and Toyota Motor Corporation. His innovative spirit and problem-solving skills have led to the development of vital technologies that enhance vehicle performance and reliability.
