Title: Innovations by Inventor Stefan Maier
Introduction
Stefan Maier is a notable inventor based in Schwieberdingen, Germany. He has made significant contributions to the field of engineering, particularly in the development of advanced fuel injection systems. With a total of 9 patents to his name, Maier's work has had a substantial impact on automotive technology.
Latest Patents
One of his latest patents is a method for measuring the lift of a valve needle of a valve and for adjusting the volume of media flow of the valve. This innovative method utilizes easily focused, high-energy radiation, allowing for a contact-free measuring operation. The radiation is directed at the valve-closure member, which is permanently joined to the valve needle in the installed valve. By performing a differential measurement in both end positions of the valve needle, the lift can be determined and corrected. This measurement is particularly suited for electromagnetically actuated fuel-injection valves in internal-combustion engines with externally supplied ignition.
Another significant patent is for a fuel injector that includes a magnetic coil. This coil's power dissipation is utilized to pre-heat the fuel flowing through the injector. The magnetic coil is strategically arranged to ensure thermal coupling with the fuel flowing through a heat exchanger segment. Additionally, a Peltier element can be arranged between the magnetic coil and the heat exchanger segment to enhance heating efficiency. Furthermore, the fuel can also be heated using a heating coil.
