Tag: Dynamic emulsion

Анотація: (English) When using gasoline-ethanol fuel blends, there is always a risk of phase separation into organic fractions and water (inherent in ethanol). The higher the ethanol content in the blend, the more significant the negative impact of phase separation into organic components and water. This paper proposes a device with no moving parts, installed in the fuel pipeline between the fuel pump and the high-pressure pump. The fuel pump outlet is connected to a splitting tee, which divides the fuel flow into two streams. These streams undergo turbulence-level homogenization within the device, and if water is present in the gasoline-ethanol mixture, it is dynamically emulsified during the homogenization process. The dynamic emulsion exiting the device then enters the engine’s high-pressure pump, where, under high-pressure conditions, it is further transformed into a nanoscale emulsion. Upon combustion in the cylinder’s combustion chamber, this emulsion eliminates soot formation and nitrogen oxide emissions while maintaining engine power output. These effects have been confirmed through testing conducted by ROUSH.
