With a total of two patents to his name, Iseyama's work focuses on enhancing the efficiency and performance of automotive engines.
Latest Patents
Iseyama's latest patents include an automotive engine idle speed control device and an idle speed control device. The automotive engine idle speed control device meters the flow rate of air supplied to the engine by bypassing an intake pipe during engine idle operation. This innovative device controls the engine idle speed by producing an actuating vacuum in response to an electrical signal, which acts on a diaphragm fixed to a valve. Additionally, adjusting means are provided to control the vacuum on the diaphragm independently of the electrical signal, allowing for precise control against external forces acting on the valve.
The idle speed control device features an electromagnetic driving portion and a flow rate controlling portion located in a bypass passage formed in a throttle chamber. This design minimizes the unfavorable effects of fluctuations in intake vacuum on the actual air flow rate, ensuring stable engine performance. The arrangement allows for effective vacuum compensation without increasing the initial leak, showcasing Iseyama's innovative approach to automotive technology.
