Title: Innovations by Peter Joppig in Internal Combustion Engine Technology.
Introduction
Peter Joppig is a notable inventor based in Korb, Germany. He has made significant contributions to the field of internal combustion engines, holding a total of 9 patents. His work primarily focuses on improving the efficiency and performance of these engines through innovative heating methods.
Latest Patents
One of Joppig's latest patents involves the control of an electrically heated pre-heating device for cold-starting internal combustion engines. In this method, the heating power is managed by a control unit of the engine electronics based on the operating data of the engine. Initially, during the preglow phase, the heating element receives full current until it reaches a reference temperature. Once this temperature is achieved, a post-heating phase begins, where the heating element is maintained at a constant temperature with reduced power. During the start-up phase, the heating element is switched off for a brief period and then reactivated as the engine speed increases.
Another significant patent by Joppig describes a method of heating the intake air for internal combustion engines. This method utilizes at least one electrically heatable heating element positioned upstream of the air inlet. The heating duration for pre-start is determined by the cooling water temperature and the temperature of the incoming air. The post-start heating period is selected independently, based solely on the cooling-water temperature.
Career Highlights
Throughout his career, Peter Joppig has worked with prestigious companies such as Mercedes-Benz and Daimler-Benz. His experience in these leading automotive firms has allowed him to develop and refine his innovative ideas in engine technology.
