This invention discloses a hydrogen-ammonia fuel injector with a swirling structure. The injector includes a fuel injector housing, an ammonia inlet assembly, an electronic control assembly, a valve assembly, an air intake assembly, and an injection assembly. The injection assembly includes an injector housing, a hydrogen-ammonia interface, a fixed sleeve, a flow pipe, a sliding sleeve, a fixing block, a return spring, and a return assembly. Swirling vanes are installed inside the flow pipe, forcing liquid ammonia and hydrogen into a high-speed swirling state. Centrifugal force and shear force are used to achieve uniform mixing of the two phases, forming a homogeneous hydrogen-ammonia fuel mixture. Combined with the hyperboloidal outlet channel at the bottom of the flow pipe, the injection flow pattern is organized, achieving an integrated function of "hydrogen premixing - forced swirling mixing - injection flow pattern organization." This fundamentally solves the combustion instability problem caused by uneven mixing, significantly improves the uniformity of the hydrogen-ammonia fuel mixture, and, combined with the flow pattern organization effect of the hyperboloidal outlet, effectively improves combustion stability and fuel utilization, reducing NOx emissions and ammonia slip.

This invention relates to a novel one-step titanium alloy wire drawing process using rollers. This process replaces the traditional stretching method with multi-angle composite roller rolling, processing the wire in a circular-elliptical-circular pattern. By rationally allocating the elongation coefficient and the horizontal angle between the rollers for each pass, continuous one-step forming of the titanium alloy wire is achieved. This process is carried out at room temperature, requiring no auxiliary lubricants or intermediate heat treatment. Only one annealing after wire forming is needed to obtain a bright wire. The final finished wire exhibits excellent mechanical properties and high dimensional accuracy, significantly simplifying the titanium alloy wire manufacturing process, reducing production costs, and making it suitable for large-scale industrial production.
