Title: Innovations of Heinz Waras in Fuel Injection Technology
Introduction
Heinz Waras is a notable inventor based in Steyr, Austria. He has made significant contributions to the field of internal combustion engines, particularly through his innovative designs in fuel injection technology. His work has implications for improving engine efficiency and reducing emissions.
Latest Patents
Heinz Waras holds a patent for a two-stage fuel-injection nozzle for internal combustion engines. This invention features a nozzle housing that terminates in a nozzle tip, with a pintle guided within the housing. The pintle is pressed by spring action against a conical valve seat in the nozzle tip. The design includes a plurality of spray holes that are selectively covered by the conical end of the pintle, which leads into a blind hole. The imaginary cylinder surface area (M) along the extension of each spray hole is smaller at the end of the first phase of the stroke than the cross-sectional area (Q) of the corresponding spray hole. To enhance emission behavior, the imaginary cylinder surface area (M) is at most 0.3 times the cross-sectional area (Q) of the corresponding spray hole, and the entrance zone into the spray hole is rounded with a radius of at least one-tenth the diameter of the spray hole.
