University of Gothenburg researchers study how bubbles in biodiesel can boost ICE energy efficiency

In Sweden, by studying how bubbles form in a drop of biodiesel, researchers at the University of Gothenburg can help future engines get the most energy out of the fuel. In an internal combustion engine, the fuel is distributed in small droplets in injection valves to maximize combustion.

In the engine, the fuel droplets are pressurized to turn into gas and burn. When gas is formed, bubbles form inside the droplets and it is these that the researchers at the University of Gothenburg have studied using femtosecond lasers.
