ABSTRACT:
A liquid injection system for internal combustion engines has a simplified pumping system, with a vacuum driven pump, assisted by an electrically driven booster pump. The liquid is delivered to the engine manifold by way of a spray nozzle incorporating an expansion chamber, into which chamber a calibrated air nozzle delivers air as a high velocity jet to impinge in atomizing, droplet forming relation on injection liquid entering the expansion chamber.
