Abstract

An additional carburettor adds water to the air fuel mixture, and heat is withdrawn from the compression stroke to vapourise the water and prevent detonation to give higher engine performance together with a decrease in nitric oxide formation. The water carburettor could be combined with a fuel carburettor with two respective float chambers for the water and fuel with their jets extending into the venturi. The float chambers would have pressure compensator tubes entering the air intake above the venturi.

Description

Beschreibung: Beimischung von Wasser mittels Verneblungsanlage zur Vrbrennugsluft für Ottomotoren bei äußerer Gemischbildung.Description: Adding water to the Combustion air for gasoline engines with external mixture formation.

Bei der Verdichtung des angesaugten kraftstoff - Luftgemisches entsteht infolge polytroper Verdichtung Wärme, welche die Temperatur des Gemisches zum Verdichtungsende hin ansteigen läßt. Nach Zündung des Gemisches beginnt dieses mit fortlaufender Flammfront zu verbrennen.When the sucked-in fuel-air mixture is compressed as a result of polytropic compression heat, which is the temperature of the mixture at the end of compression can rise. After ignition of the mixture, this begins with a continuous Burn flame front.

Dabei steigt der Druck infolge weiterer Temperaturernonung stetig an. Gleichzeitig steigt infolge dieser Isovolumen Zustandsänderung die Temperatur im restlichen noch nicht verbrannten kraftstoff - Zuftgemisch an. wird dabei die Selbstzündungstemperatur des Gemisches erreicht, verbrennt das restliche Gemisch schlagartig bei hoher mechanischer Belastung des Motors. Nachfolgend beschriebene Erfindung sieht vor, dass dem Praft stoffluftgemlsch für Ottomotoren mittels einer separaten Verneblungsanlage der Verbrennungsluft gleich dem Kraftstoff zusätzlich Wasser in vernebelter Form bei ebenfalls äußerer Gemischbildung beigemischt wird.The pressure rises steadily as a result of further temperature reduction at. At the same time, as a result of this isovolume change in state, the temperature rises in the remaining fuel / air mixture that has not yet been burned. is the When the auto-ignition temperature of the mixture is reached, the remainder of the mixture burns suddenly with high mechanical load on the motor. Described below Invention provides that the test stoffluftgemlsch for gasoline engines by means of a separate nebulization system for the combustion air as well as the fuel Water is added in atomized form when the mixture is also formed externally.

Dieses vernebelte Wasser wird infolge der bei der Verdichtung der Verbrennungsluft entstehenden Wärme verdampft und entzieht dabei der Verbrennungsluft die für die Verdampfung erforderliche Wärme. Dadurch wird f die Verdichtungsendtemperatur gesenkt und die Klopffestigkeit des Rotors erhöht.This atomized water is due to the compression of the The heat generated by combustion air evaporates and is extracted from the combustion air the heat required for evaporation. This makes f the compression end temperature lowered and the knock resistance of the rotor increased.

Da die Verbrennungstemperatur auf die Verdichtungsendtemperatur aufbaut, liegt auch diese um den entsprechenden Betrag niedriger. Diese niedrigere Verbrennungstemperatur hat eine geringere Stickoxidbildung zur Folge.Since the combustion temperature is based on the final compression temperature, if this is also lower by the corresponding amount. This lower combustion temperature results in less nitrogen oxide formation.

Infolge des Wärmeentzuges durch das zu verdampfende Wasser während des Verdichtungshubes verringertsich der Polytropeneiponent für den Verdichtungsvorgang und damit ie zu leistende Verdichtungsarbeit. Bei gleicher Wärmezufuhr währena der Verbrennung bedeutet dies höherei lotorleistung bei gleichem traftstofiverbrauch.As a result of the removal of heat by the water to be evaporated during the compression stroke decreases the polytropic component for the compression process and thus the compression work to be performed. With the same heat input, the Combustion means higher engine performance with the same fuel consumption.
