A method and apparatus for delivering metered and atomized quantities of liquid to an internal combustion engine wherein the liquid is metered in a T-shaped fitting having a liquid supply arm, an air arm which is perpendicular to the supply arm, and a delivery arm is aligned with the supply arm. Liquid is pumped from a liquid source to fill the supply and part of the delivery arm of the T-shaped fitting. A predetermined pulse of pressurized air is delivered to the air arm of the T-shaped fitting, transversely striking and severing the accumulated liquid in the delivery arm from the liquid in the supply arm to form a liquid slug. The pressurized air pulse forces the liquid slug out of the T-shaped fitting into an acceleration pipe, accelerates the liquid slug through the acceleration pipe, stores kinetic energy in the moving liquid slug, moves the liquid slug through a nozzle, atomizes the liquid slug, and cleans the nozzle and preconnected passages of residual liquid. The quantity of liquid atomized is controlled by regulating the amount of liquid delivered to the supply arm and the timing of the atomization is controlled by timing the delivery of the pressurized air pulse to the air arm.
