Latest Patents

One of Minato's latest inventions is a variable valve driving device designed to accurately control the lift amount of valves while being cost-effective to manufacture. This device includes valves that serve as either intake or exhaust valves of an engine, springs that bias the valves in the closing direction, and a cam that presses the valves open against the springs' biasing force. Additionally, it features a piston joined to the valves, a control chamber for piston insertion, and a control mechanism that regulates the valve closing timing by managing the introduction and discharge of a working fluid.

Another notable patent is the exhaust valve drive control method and device. This invention provides a method for controlling the closing operation of an exhaust valve in an internal combustion engine. It determines the current position of the exhaust valve and the engine's rotation speed, calculating the timing for the piston to arrive at the valve's position. The method ensures that the closing operation of the exhaust valve is initiated and temporarily halted at precise intervals to optimize performance.
