Latest Patents
**System for Preventing Knocking in a Combustion Engine.** This invention uses an engine-vibration sensor to detect knocking and produce a knock signal. In response, the system enriches the air-fuel mixture and retards ignition timing to help prevent knocking.
**Fuel-Vapor Emission Control System for an Automotive Engine.** This system captures fuel vapor in a canister connected to a carburetor’s float chamber and the fuel tank. It uses vacuum-operated and solenoid-operated controls to regulate purging, with a vehicle or engine speed signal governing when purging occurs to help avoid engine stalling.
Career Highlights
Yuasa’s listed inventions focus on two practical automotive challenges: reducing engine knock and controlling fuel-vapor emissions. Together, they illustrate approaches to engine management that coordinate sensing, fuel delivery, ignition timing, and vapor purging.
