Abstract

Injector for injecting coolant liquid such as water into the combustion chamber of internal combustion engines. This injection system is used for saving fuel and for increasing power. The coolant liquid injected is evaporated and the supply of this liquid is regulated in relation to the temperature of the cylinder walls and fuel suppled to ensure complete coolant evaporation. The coolant is injected after ignition so that the combustion process is not affected. The temperature in the combustion chamber is lowered and the vapour generated compensates largely for the compressed fluid volume reduction caused by cooling. Lower heat losses to the combustion chamber walls result and on using water as coolant the high specific heat content of exhaust gas ensures that the exhausted mixture expands to a lesser extent than conventional exhaust gas.

Description

Titel: Einspritzung von Kühlflüssigkeit (wie z.B.Title: Injection of coolant (e.g.

Wasser) in den Verbrennungsraum von Verbrennungsmotoren. Water) in the combustion chamber of internal combustion engines.

Anwendungsgebiet: Otto-,Diesel-,Wankel- und andere Verbrennungsmotoren.Area of application: Otto, diesel, Wankel and other internal combustion engines.

Zweck: @raftstoffeinsparung bei gleichzeitiger Leistungssteigerung.Purpose: @saving fuel while increasing performance at the same time.

Kritik des Standes der Technik: Zu grofer Energieverlust durch Wärmeabgabe des Verbrennungsgases an die Umwandung der Verbrennungsräume.Criticism of the state of the art: Too great a loss of energy due to the dissipation of heat of the combustion gas to the conversion of the combustion chambers.

AufSabe: Der Erfindung liegt die Aufgabe zugrunde, bei den gegenwärtig gebrauchten Verbrennungsmotoren unter Beibehaltung der zur Zeit gebrauchlichen Kraftstolfe (Benzin,Diesel,Gas) zu einer vergrößerten Energieausnutzung zu gelangen.Task: The invention is based on the task at present used internal combustion engines while maintaining the fuel currently in use (Petrol, diesel, gas) to achieve an increased use of energy.

Lösung: Nach der Einspritzung von Kühlflüssigkeit kommt es zur Verdampfung derselben.Die zugeführte Flüssigkeitsmenge soll in Abhängigkeit von der Tem-,eratur der Umwandlung des Verbrennungsraumes und der zugeführten Kraftstoffmenge derart geregelt werden, daß sie vollständig verdampft und nicht an der Umwandung des Verbrennungsraumes @ondensiert. Die Einspritzung soll nach der Zündung des Kraftstoffgasgemisches so spät erfolgen, da der Verbrennungsvorgang unbeeinflußt bleibt.Solution: After cooling liquid has been injected, it evaporates The amount of liquid supplied should depend on the temperature the conversion of the combustion chamber and the amount of fuel supplied be regulated so that it evaporates completely and not on the wall of the combustion chamber @ condensed. The injection should be like this after the ignition of the fuel-gas mixture take place late, since the combustion process remains unaffected.

Erzielbare Vorteile: Durch d.as Verdampfen der Kühlflüssigkeit wird die Temperatur in dem Verbrennungsraum gesenkt. Der entstehende Dampf kompensiert größtenteils die entstehende Druckvolumenminderung als Folge der Abkühlung. Das entstandene neue Verbrennungsgas- Dampfgemisch führt mit seiner geringeren Temperatur zu entsprechend geringeren Wärmeverlusten durch Kühlung der Wandung des Verbrennungsraumes. Zusätzlich wirkt sich die niedrigere Temperatur und der vor allem bei Verwendung von Wasser als Kühlflüssigkeit größere spezifische Wärmeinhalt (165 entstandenen Verbrennungsgas- Dampfgemisches dahingehend aus, daß unter Dekompression das Druckvolumen sich wesentlich weniger stark vermindert, als ein normales Verbrennungsgas ohne Kühlzusatz.Achievable advantages: The evaporation of the coolant the temperature in the combustion chamber is lowered. The resulting steam compensates largely the resulting reduction in print volume as a result of cooling. That resulting new combustion gas-vapor mixture leads with its lower temperature to correspondingly lower heat losses by cooling the walls of the combustion chamber. In addition, the lower temperature and especially when using it has an effect the specific heat content of water as a coolant is greater (165 Combustion gas-vapor mixture to the effect that under decompression the pressure volume decreases significantly less than a normal combustion gas without it Cooling additive.
