ABSTRACT:
A fuel injector of the invention comprises a plurality of parallel, threadlike tubes for admitting electrostatically charged fuel and an accelerator electrode biased at the opposite potential to that applied to a fuel charging electrode. The fuel admitted through the parallel tubes is atomized at the outlet port of the tubes as a result of electrostatic repulsion between charged particles, and attracted and accelerated by an electrode spaced from the outlet port of the tubes. A control electrode may be provided spaced from the accelerator electrode adjacent to the outlet port of the tubes and biased at a potential with respect to the accelerator electrode much lower than the potential applied across the accelerator and fuel-charging electrodes. By varying the potential at the control electrode, the fuel quantity delivered can effectively be controlled.
