Authors Abstract
Content
This work discusses the possibility of application of electrostatic forces and/or properties to control the spray development within in-cylinder flows. The liquid fuel is assumed to pass through a -12 kV charging potential before it is pumped into the combustion chamber. The development of the resulting charged droplets is then controlled by charge spread on the boundaries. The results indicate considerable improvement as far as the wall wetting is concerned. In addition, and though substantially suppressed by the late stages of the compression stroke, the in-cylinder reverse tumble is promoted by the electrostatic repulsion forces on the piston surface.
