Title: Nobuhiko Matsunaga: Innovator in Engine Technology
Introduction
Nobuhiko Matsunaga is a prominent inventor based in Iwata, Japan. He has made significant contributions to the field of engine technology, holding a total of 3 patents. His work focuses on innovative mechanisms that enhance the performance and efficiency of internal combustion engines.
Latest Patents
Matsunaga's latest patents include a valve-actuating variable cam for engines. This invention discloses a cam comprising a camshaft journaled for rotation by a reciprocating machine. The camshaft is driven in a timed relationship with the machine, featuring a first cam fixed upon the camshaft and rotatable with it. Additionally, a second cam is fixed for rotation with the camshaft and is movable relative to the first cam in a direction radial to the axis of rotation of the camshaft. The design includes a shift rod that is slidably mounted within the camshaft, which drives a key element that engages the second cam. This innovative mechanism allows for precise control of valve engagement.
Another notable patent is the engine valve operating system. This invention presents various embodiments of valve-actuating mechanisms for reciprocating machines, such as internal combustion engines. The system allows for controlled lift of the valve by providing a pair of cams on the camshaft that cooperate with the same follower. One of the cams is radially shiftable, enabling it to be brought into an operative position or an inoperative position, thus controlling the lift of the valve effectively.
