Engine system and method of operation using matched fuel injector and piston to optimize injection jet interaction with combustion bowl
Operating the engine includes injecting liquid fuel directly into the combustion cylinder through exactly seven injection outlets in the fuel injector, and sweeping an injection jet of fuel against a ramp of a central cone within a combustion bowl in the piston. Operating the engine also includes di...

| description | Operating the engine includes injecting liquid fuel directly into the combustion cylinder through exactly seven injection outlets in the fuel injector, and sweeping an injection jet of fuel against a ramp of a central cone within a combustion bowl in the piston. Operating the engine also includes directing fuel of the swept injection jet to a recessed projection extending circumferentially around the combustion bowl, and divide the directed fuel into a separated small flow above an inclined inner edge surface formed by the piston end face and a circulating large flow propelled upward and inward from the recessed projection toward a fire deck surface of the engine. The directly injected liquid fuel is automatically ignited in the combustion cylinder. Related engine systems and combustion system devices are disclosed.
操作发动机包括通过燃料喷射器中的恰好七个喷射出口将液体燃料直接喷射到燃烧气缸中，并且对着活塞中的燃烧碗内的中心锥体的斜面扫掠燃料的喷射射流。操作发动机还包括将扫掠的喷射射流的燃料引导到围绕燃烧碗周向延伸的凹入突出部，并且将引导的燃料分成在由活塞端面形成的倾斜内缘表面上方的分离小流和朝向发动机的防火甲板表面从凹入突出部向上和向内推进的循环大流。直接喷射的液体燃料在燃烧气缸中自动点火。公开了相 |
