Latest Patents

One of Masaaki Katoh's latest patents is a valve operating device for internal combustion engines. This system allows for a valve operation mode to be changed from low-speed to high-speed based on engine speed and the temperature of the working oil. It ensures that the valve operating mode is adjusted only when the working oil temperature exceeds a predetermined value. Additionally, the system is designed to terminate fuel supply to the engine when the oil temperature is below a certain threshold while the engine speed is high.

Another notable patent is an apparatus for changing the operation timing of valves for internal combustion engines. This invention involves a valve operating apparatus where intake or exhaust valves are operated by rocker arms driven by cams. It features a hydraulically operated coupling mechanism that selectively connects or disconnects adjacent rocker arms, allowing for variations in valve operation timing under different engine conditions. The fluid circuit for this mechanism includes a valve that is closed during low-speed operation and opened during high-speed operation.
