Title: Haruhito Fujimura: Innovator in Variable Valve Timing Technologies
Introduction
Haruhito Fujimura, a prominent inventor based in Toyota, Japan, is recognized for his contributions to automotive technology, specifically in variable valve timing apparatus and systems. With a total of six patents to his name, Fujimura's innovations are integral to the efficiency and performance of internal combustion engines.
Latest Patents
Fujimura's latest patents include a sophisticated variable valve timing apparatus. This control device features two control modes for an electric power supply to an electromagnetic solenoid, activated based on the discrepancies between the sensed value of the phase and a target value. The special mode is triggered when the sensed value crosses a specific threshold, allowing for a larger opening degree of the advancing port compared to the normal mode.
Another significant innovation is the variable valve actuation apparatus for internal combustion engines. In this patent, a rotor within the variable valve timing mechanism is fixed to a camshaft's end using multiple bolts. What sets this design apart is the unique fastening of an oil control valve to the rotor, which streamlines maintenance by allowing easy removal without the need for realignment of the rotor during oil control valve replacement.
