With a total of 2 patents, Sekino's work has had a lasting impact on engine performance and efficiency.
Latest Patents
One of Sekino's latest patents is a fuel injection timing control system for internal combustion engines. This innovative system utilizes a fluid actuator with a movable wall member to control the fuel injection timing of a fuel injection pump. The control system generates a control voltage based on the engine's rotational speed and the amount of fuel injected. This voltage is then compared to an injection timing voltage to produce a deviation signal, which actuates an electromagnetically operated control valve. This allows for automatic adjustment of the fuel injection timing, optimizing engine performance under varying conditions.
Another significant patent is for an alternator driven by a vehicle engine. In this design, an internal combustion engine is adjusted to a preset speed by an engine governor. The engine's driving force is transmitted to the alternator through a magnetic slip coupling. An excitation control circuit regulates the excitation current to the magnetic slip coupling, ensuring that the alternator produces alternating current with a highly accurate preset frequency.
