Title: Takuya Kado: Innovator in Engine Technology
Introduction
Takuya Kado is a prominent inventor based in Shizuoka, Japan. He has made significant contributions to the field of engine technology, holding a total of 9 patents. His innovative designs focus on improving engine performance and efficiency, particularly in marine applications.
Latest Patents
One of Kado's latest patents is an advanced engine and outboard motor design. This engine features a catalyst located within the exhaust passage, which guides exhaust from the combustion chamber. The system includes a controller that manages the throttle valve and fuel injector. In cases of overheating, the controller adjusts the throttle valve's opening degree or the fuel injection amount to reduce the crankshaft's rotational speed. It also modifies the fuel injection to achieve a richer air-fuel ratio than the stoichiometric ratio.
Another notable patent is the propulsion unit control system designed for boats with multiple propulsion units. This system connects the propulsion units electrically and synchronizes their engine speeds based on inputs from two adjacent operation levers. The control system calculates the deviation between the average engine speed of a reference propulsion unit and that of the unit to be synchronized. It then corrects the throttle opening of the propulsion unit to ensure that the engine speeds are aligned.
