Title: Takahiro Aki and His Engine-Control Inventions.

Introduction

Takahiro Aki is an inventor associated with Kobe, Japan. His patent work focuses on engine systems, including gas-leak detection and fuel-injection control. His listed portfolio includes 2 patents.

Latest Patents

Aki’s patent, “Gas Leakage Detection and Fail-Safe Control Method for Gas-Fueled Internal Combustion Engine and Apparatus for Implementing the Same,” describes a system for detecting gas leaks while an engine is stopped. It compares gas pressure at the time the shut-off valve closes with pressure measured after a prescribed interval. The method can also accumulate pressure decreases or their rates across engine stops to identify leakage. When a leak is detected, the system closes the gas shut-off valve and issues a warning.

His patent, “Fuel Injection Control Apparatus for Engines,” concerns vehicle engines, particularly those used in golf carts. When the accelerator pedal is pressed to start the engine, a controller activates the starter and commands one initial fuel injection. The design allows the initial injection and associated ignition to occur even when no pulse signal is received from the crank-angle sensor.

Career Highlights

The available patent descriptions show Aki’s work addressing engine startup and operational safety. One invention focuses on detecting gas leakage and triggering a fail-safe response, while the other coordinates starter and fuel-injection control during startup.

Collaborations

Aki’s listed coworkers include Hiroki Matsuoka and Mikio Hamada. No company affiliation is specified in the provided information.

Conclusion

Takahiro Aki’s two listed patents address practical engine-control challenges, combining gas-leak safety measures with controlled fuel injection during startup.
