Title: Akinori Kojima: Innovator in Marine Propulsion Systems
Introduction
Akinori Kojima is a notable inventor based in Hamamatsu, Japan. He has made significant contributions to the field of marine propulsion systems, holding a total of 8 patents. His innovative designs focus on enhancing security and efficiency in outboard motors.
Latest Patents
Kojima's latest patents include a locking device for outboard motors. This invention features several embodiments of improved security systems for marine propulsion systems that do not have a continuously available source of electrical energy. These systems incorporate an electric key reader powered by a manually operated electrical power supply during starting, ensuring protection against theft. In one embodiment, if there is a failure in the electrical power supply for the security system, the speed of the propulsion system is limited, allowing the rightful owner to reach a service area. Another significant patent is the water jacket arrangement for marine two-cycle internal combustion engines. This design includes an outboard motor with an improved cooling system, where liquid coolant circulates through an exhaust manifold cooling jacket, then through a cylinder head cooling jacket, and finally through an upper portion of the cylinder block cooling jacket. A thermostatic valve controls the flow from the upper cylinder block cooling jacket to the lower cylinder block cooling jacket, preventing the quenching of the intake charge by coolant that has not reached operating temperature.
