Fuel nozzle and swirler

The engine may utilize a combustor to burn fuel to drive the engine. The fuel nozzle assembly may supply fuel to the combustor for combustion or ignition of the fuel. The fuel nozzle assembly may include a swirler and a fuel nozzle to supply a mixture of fuel and air for combustion. The use of alternative fuels that burn at higher temperatures or velocities compared to conventional fuels, requiring improved fuel introduction without flame retention or tempering, may meet increased efficiency and emission requirements. 发动机可以利用燃烧器来燃烧燃料，以驱动发动机。燃料喷嘴组件可以将燃料供应到燃烧器，用于燃料的燃烧或点火。燃料喷嘴组件可以包括旋流器和燃料喷嘴，以供应燃料和空气的混合物，用于燃烧。使用替代燃料可以满足增加效率和满足排放需求，该替代燃料与传统燃料相比，以更高的温度或更高的速度燃烧，从而需要改进的燃料引入，而不出现火焰保持或回火。
