An experimental study of gasoline effects on injection rate, momentum flux and spray characteristics using a common rail diesel injection system

► Higher injection rate in Diesel than gasoline fuel. ► Lower gasoline viscosity implies a faster opening and specially a faster injector closing. ► The results show not clear differences between diesel and gasoline for momentum flux. ► Similar spray penetration for both fuels independently of the nozzle diameter. ► A correlation for spray penetration is presented both for gasoline and diesel fuel.
