Title: Masahiko Shinagawa: Innovator in Fuel Injection Technology
Introduction
Masahiko Shinagawa is a notable inventor based in Higashimatsuyama, Japan. He has made significant contributions to the field of fuel injection systems, holding 2 patents that enhance the efficiency and safety of internal combustion engines.
Latest Patents
One of his latest patents is a fuel injection control system for internal combustion engines. This innovative system allows for feedback mode control when the system is functioning normally. In the event of an abnormality, the system switches to an open loop mode via a limp home circuit, enabling the vehicle to be driven slowly to a safe location for servicing. The limp home circuit includes fuel cutoff mechanisms that interrupt the fuel supply when the engine's rotational speed exceeds a predetermined value.
Another significant patent is a fuel-injection device that features a solenoid valve. This device adjusts the fuel-injection level of a pump by modifying the throttling of the fuel-injection passage. The driving pulse for the solenoid valve is carefully designed, taking various factors into account to ensure responsiveness. The pulse consists of segments with varying duty ratios to optimize performance, considering voltage changes and unique characteristics of the fuel-injection pumps.
