Description

Treibstoffmischungen Es sind Treibstoffmischungen bekannt, welche aroma.tische Amine, wie N-Alkylanilin, als' Antiklopfmittel, sowie primäre und/oder sekundäre. aliphatische, cycloaliphatische oder araliphatische Amine mit mindestens einem Kohfenwasserstoffrest von mindestens 5 C-Atomen enthalten. Diese Treibstoffmischungen bleiben beim Stehen im Licht niederschlagsfrei und geben keinerlei Verharzungen bei ihrer Verwendung in Viertaktverbrennungsmotoren. Beim Betreiben von Zweitaktvergasermotor.en hingegen hat es sich gezeigt, daß nach einem längeren Betrieb. solcher Moteren mit den erwähnten Treibstoffmischungen, noch geringe Verklobungen und Verharzung-en an Kolbenringen, Überströrnkanälen und Auslaßschlitzen auftreten können.Fuel mixtures Fuel mixtures are known which have aromatic amines, such as N-alkylaniline, as anti-knock agents, as well as primary and / or secondary. Contain aliphatic, cycloaliphatic or araliphatic amines with at least one hydrocarbon radical of at least 5 carbon atoms. These fuel mixtures remain free of precipitation when standing in the light and do not give off any resinification when they are used in four-stroke internal combustion engines. When operating two-stroke carburetor engines, however, it has been shown that after a long period of operation. Such engines with the mentioned fuel mixtures, still slight clogging and resinification on piston rings, overflow channels and outlet slots can occur.

Gegenstand der Erfindung sind nun verbesserte Treibstoffinischungen mit einem Gehalt an N-Alkylanilin als Antiklopfmittel und von primären und/ oder sekundären aliphatischen, cycloaliphatischen oder araliphatischen Aminen mit mindestens einem Kohlenwasserstoffrest von mindestens 5 C-Atomen als Stabililsatoren, gekennzeichnet durch einen Zusatz von N-substituierten Hexahydrophthalsäureimiden.The invention now relates to improved fuel mixtures containing N-alkylaniline as an anti-knock agent and primary and / or secondary aliphatic, cycloaliphatic or araliphatic amines with at least one hydrocarbon radical of at least 5 carbon atoms as stabilizers, characterized by the addition of N-substituted Hexahydrophthalic acid imides.

Obwohl sich der Vorteil der erfindungsgemäßen Treibstoffmischungen hauptsächlich bei ihrer Ver-Nvendung in Zweitaktvergasermotoren zeigt, indem auch nach längerem Betreiben solcher Motore mit den -neuen Treibstoffmischungen keinerlei Verklebungen und, Verharzungen an den Motorenteilen mehr auftreten, können die neuen Treibstoffmischungen gleichermaßen auch für Viertaktmotoren verwendet werden.Although the advantage of the fuel mixtures according to the invention shows mainly in their use in two-stroke carburetor engines by even after a long period of operation of such engines with the -new fuel mixtures none The new ones can cause sticking and gumming on the engine parts Fuel blends can be used equally well for four-stroke engines.

Als Hexahydrophthalsäureimidzusätze kommen z. B. in Frage: XL-Methyl-, -Äthyl-, -n-Propyl-, -Isopropyl-, -n-Butyl-, -Isobutyl-, -n-Amyl-, -Isoamyl-, -n#Hexyl-, Isohe x*yl-, -Octadecyl-, N, N-hexamethylen-bis-,' I\r-Cyclohexyl-, -Phenyl- und Acetoxyäthyl-hexahydrophthalsäureimid oder Mischungen solcher Stoffe.As hexahydrophthalimide additives come z. B. in question: XL-methyl-, -ethyl-, -n-propyl-, -isopropyl-, -n-butyl-, -isobutyl-, -n-amyl-, -isoamyl-, -n # hexyl-, Isohexyl-, -octadecyl-, N, N-hexamethylene-bis-, I \ r-cyclohexyl-, -phenyl- and acetoxyethyl-hexahydrophthalimide or mixtures of such substances.

Die zuzusetzenden Mengen solcher Hexahydrophthalsäureimide liegen zwischen etwa o,o5 und etwa i Gewichtsprozent und insbesondere zwischen etwa o,i und etwa o,5 Gewichtsprozent, bezogen auf N-Alkylanilin.The amounts of such hexahydrophthalic acid imides to be added are between about 0.05 and about i percent by weight, and in particular between about 0.05 and about 0.5 percent by weight based on N-alkylaniline.

Das N-Alkylanilin, das Amin und das Hexahydrophthalsäureimid können dem Treibstoff getrennt zugesetzt werden, in der Regel empfiehlt es sich aber, eine Mischung aller drei Komponenten dem Motorenkraftstoff zuzuführen.The N-alkylaniline, the amine and the hexahydrophthalic acid imide can can be added separately to the fuel, but it is usually advisable to use a Adding a mixture of all three components to the engine fuel.

Beispiel i 98 Gewichtsteilen eines Treibstoffes, der zu go% aus Krackbenzin und zu -io% aus einer benzolisehen Fraktion besteht, werden 4976 Gewichtsteile Monomethylanilin, o,o:2o Gewichtsteile Dicyclohexylamin und 0,004Gewichtsteile N-Cyclohexyl-hexahydrophthalsäureimid zugesetzt. Bei Verwendung eines solchen Treibstoffgemisches in einem Zweitaktvergasermotor treten nach 3ooo Fahrkilometern noch keinerlei Verklebungen und Verharzungen an Kolbenringen, überströmk-tanälen und Auslaßschlitzen auf.Example i 98 parts by weight of a fuel, the go% from cracked gasoline and to -io% consists of a benzene fraction, 4976 parts by weight of monomethylaniline, o, o: 2o parts by weight of dicyclohexylamine and 0.004 parts by weight of N-cyclohexylhexahydrophthalic acid imide added. When using such a fuel mixture in a two-stroke carburetor engine After 3,000 kilometers there are still no adhesions or gumming Piston rings, overflow channels and outlet slots.

Beispiel 2 97 Gewichtsteilen eines Treibstoffes, der zu 75 Teilen aus Krackbenzin und zu 25 Teilen aus einer benzolischen Fraktion besteht, werden 2,964 Gewichtsteilt Monomethylanilin, 0,03o Gewichtsteile Isoamylamin und o,oo6 Gewichtsteile N-Octa,decylhexahydrophthalsäureimid zugesetzt. Bei Verwendung dieses Treibstoffgemisch#s in einem Viertaktmotor treten nach 5oooFahrkilometern noch keinerlei Verklebungen und Verharzungen an Kolbenstirnflächen, Kolbenringen und Ventilen auf.EXAMPLE 2 97 parts by weight of a fuel consisting of 75 parts of cracked gasoline and 25 parts of a benzene fraction are added to 2.964 parts by weight of monomethylaniline, 0.030 parts by weight of isoamylamine and 0.06 parts by weight of N-octa, decylhexahydrophthalic acid imide. When using this fuel mixture in a four-stroke engine, no sticking or resinification of any kind on piston faces, piston rings or valves occurs after 500 kilometers of driving.
