Title: **Hidenobu Nagase: Innovator in Internal Combustion Engine Technologies**
Introduction
Hidenobu Nagase, a prominent inventor based in Saitama, Japan, has significantly contributed to advancements in internal combustion engine technologies. With a remarkable portfolio of 10 patents, he has demonstrated his expertise and commitment to innovation in the automotive industry.
Latest Patents
Among his latest innovations, Nagase has developed a *fuel injection control system for internal combustion engines*, which features at least one unit injector for each cylinder. This system includes an actuator to vary the stroke of the plunger of each unit injector. When the calculated rise ratio of the engine's rotational speed exceeds a designated threshold, the actuator is adjusted to a specific position, effectively preventing an abnormal increase in engine speed. Additionally, the system detects no-load conditions and alters actuator positions accordingly.
Another significant invention is a *valve operating system for internal combustion engines*. This system consists of a valve-driving piston, which is designed to work within a cylinder body and is connected to an engine valve that is spring-biased to close. With a check valve and orifice regulating the oil pressure needed to operate the engine valve, the system effectively mitigates the effects of viscosity variations in the working oil, ensuring consistent performance.
