Bauer S, Zhang H, Pfeifer A, Wenzlawski K.Numerically and results were represented. Using this detailed model, behavior of the piezo injector,Įffects of the injector parameters on the fuel flow were investigated In model, fuel flows from the common rail toĪ tee that separates the flow into two paths: fuel gallery and valve with the Input voltage in the entrance is used to describe the piezo actuatorįorce for piezo-electric material. ![]() Predicted based on the geometry and the physical quantities describing theĮquipment. The hydraulic and mechanical component interaction is modeled Piezo-actuated common rail injector fluid-mechanical model with detail isĭemonstrated. They provide exact combustion inside the combustion chamber. Pulverized fuel droplets are evaporated and oxidized in a very short time and To ultra-high pressure in piezo-injection systems, fuel droplets are scaledĭown into a smaller particle form and thus provided more efficient combustion. This high-tech instrument decreases fuel consumption, thereby harmfulĮxhaust emissions are also lowered especially in diesel ignition engines. Common rail injectors are often utilized in today’s automobile engines’ fuel ![]()
