Title: The Innovative Mind of David W. Deppe
Introduction
David W. Deppe, an accomplished inventor based in Marshall, Michigan, has made significant contributions to the field of internal combustion engine technology. With a total of five patents under his name, Deppe's work reflects his dedication to enhancing performance and efficiency in heavy-duty diesel engines.
Latest Patents
Among his latest innovations, Deppe's patents focus on advanced exhaust gas recirculation (EGR) systems designed for heavy-duty diesel engines. One notable patent describes an EGR assembly mounted on the exhaust system of an internal combustion engine. This assembly features an EGR valve that moves between open and closed positions to communicate exhaust gas back to the intake manifold effectively. Incorporating an electric motor and a gear train, the EGR valve responds dynamically to changes in electrical input signals. Additionally, this patent includes a cooling chamber that allows for the use of more cost-effective electrical components rated for lower temperatures.
Another significant patent outlines an improved actuator for the EGR system, which utilizes a valve that remains closed under gas pressure until it begins to open. This design ensures that the valve operates efficiently, providing higher force at lower speeds as it opens against exhaust gas pressure, then reducing force while increasing speed as it reaches a fully open position.
