A cleansing agent, for example water, for an internal combustion engine is added in proportion to the flow rate of the fuel, air or fuel/air mixture supplied to the engine. The addition is controlled by a fluid flow sensor (10) which produces a pulse output indicative of the fluid flow rate. The output is supplied to a conditioning circuit (30) which produces a voltage spike for actuating an injector (16A) in a mixing chamber (26). Direct measurement of the fluid flow rate provides an immediate and accurate indication of the amount of additive required as the flow rate changes. |
