Method and device for automatic injection of an additive into the fuel tank of a motor vehicle

摘要

A method and apparatus for the automatic injection of an additive into the fuel tank of a motor vehicle, from an on-board additive tank in which the quantity of additive to be withdrawn from the additive tank is determined using an on-board computation unit, and the quantity of additive thus determined is injected by pulsed atomization, this atomization being carried out directly into the liquid bulk of the fuel. This pulsed atomization is preferably carried out by controlling a positive-displacement piston, where the number of strokes of the piston which is automatically determined as a function of the quantity of the additive to be withdrawn.
