Abstract

SE PRESENTAN COMPOSICIONES PARA UN COMBUSTIBLE DE UN MOTOR QUE COMPRENDEN UN COMBUSTIBLE NORMALMENTE LIQUIDO CON UN PUNTO DE EBULLICION EN LA ZONA DE EL DE LA GASOLINA, Y (A) UN AMINOFENOL DE LA FORMULA (I) EN DONDE CADA A ES INDEPENDIENTEMENTE H O UN GRUPO HIDROCARBIL, CADA T ES INDEPENDIENTEMENTE H O UN GRUPO HIDROCARBIL DE HASTA 28 ATOMOS DE CARBONO, A, B Y C SON CADA UNA INDEPENDIENTEMENTE UN ENTERO QUE VALE AL MENOS 1 CON LA CONDICION DE QUE LA SUMA DE A, B Y C NO EXCEDA DE LAS VALENCIAS INSATISFECHAS DE AR; Y AR ES UNA MOLECULA AROMATICA DE UN ANILLO SIMPLE, DE UN ANILLO POLINUCLEAR FUNDIDO O UN ANILLO POLINUCLEAR ENLAZADO QUE TIENE ENTRE 0 Y 3 SUBSTITUYENTES OPCIONALES SELECCIONADOS ENTRE EL GRUPO QUE CONSTA ESENCIALMENTE DE ALQUIL INFERIOR, ALCOXIL INFERIOR, NITRO, ALQUIL INFERIOR CARBOXIDO, NITROSO, HALO Y COMBINACIONES DE DOS O MAS DE DICHOS SUBSTITUYENTES OPCIONALES; Y (B) UN AMINO DE LA FORMULA GENERAL (II) EN LA QUE R1 ES UN GRUPO HIDROCARBIL QUE CONTIENE ENTRE 8 Y 24 ATOMOS DECARBONO, R2 Y R3 SON CADA UNA INDEPENDIENTEMENTE H, UN GRUPO DE HIDROCARBIL QUE CONTIENE ENTRE 1 Y 24 ATOMOS DE CARBONO O UN GRUPO DE LA FORMULA GENERAL (III) EN LA QUE R5 ES UN GRUPO ALQUILENO QUE CONTIENE ENTRE 2 Y 8 ATOMOS DE CARBONO, Y R2 Y R3 SON SEGUN SE HAN DEFINIDO ANTERIORMENTE, CADA R4 ES INDEPENDIENTEMENTE UN GRUPO ALQUILENO QUE CONTIENE ENTRE 2 Y 8 ATOMOS DE CARBONO, Y CADA X, Y Y Z ES INDEPENDIENTEMENTE UN ENTERO ENTRE 0 Y 20. EN UNA CONFORMACION, LOS COMPONENTES (A) Y (B) ESTAN PRESENTES EN CANTIDADES SUFICIENTES PARA SUMINISTRAR UNA LIMPIEZA TOTAL DEL SISTEMA DE ADMISION. EN OTRA CONFORMACION, LOS COMPONENTES (A) Y (B) ESTAN PRESENTES EN CANTIDADES SUFICIENTES PARA EVITAR O REDUCIR LA FORMACION DE DEPOSITOS EN LAS VALVULAS DE ADMISION O PARA SEPARAR LOS MISMOS CUANDO YA SE HAYAN FORMADO. TAMBIEN SE PRESENTAN METODOS PARA SUMINISTRAR UNA LIMPIEZA TOTAL DEL SISTEMA DE ADMISION Y EVITAR O REDUCIR LA FORMACION DE DEPOSITOS EN LAS VALVULAS DE ADMISION O DE SEPARAR LOS MISMOS.COMPOSITIONS ARE PRESENTED FOR A FUEL OF AN ENGINE INCLUDING A FUEL NORMALLY LIQUID WITH A BOILING POINT IN THE AREA OF GASOLINE, AND (A) AN AMINOPHENOL OF FORMULA (I) WHERE EACH ONE IS INDEPENDENTLY HO HYDROCARBIL, EACH T IS INDEPENDENTLY HO A HYDROCARBON GROUP OF UP TO 28 ATOMS OF CARBON, A, BYC ARE EACH ONE INDEPENDENTLY AN INTEGER THAT IS VALUE AT LEAST 1 WITH THE CONDITION THAT THE SUM OF A, BYC DOES NOT EXCEED THE UNSATISFIED VALENCIES ; AND AR IS AN AROMATIC MOLECULA OF A SINGLE RING, OF A FUSED POLYNUCLEAR RING OR A LINKED POLYNUCLEAR RING THAT HAS BETWEEN 0 AND 3 OPTIONAL SUBSTITUTES SELECTED BETWEEN THE GROUP THAT IS ESSENTIALLY OF LOWER RENTAL, ALCOIL, ALCO , HALO AND COMBINATIONS OF TWO OR MORE OF SUCH OPTIONAL SUBSTITUTES; AND (B) AN AMINO OF THE GENERAL FORMULA (II) IN WHICH R1 IS A HYDROCARBON GROUP THAT CONTAINS BETWEEN 8 AND 24 ATOMS OF CARBON, R2 AND R3 ARE EACH ONE INDEPENDENTLY H, A GROUP OF HYDROCARBON CONTAINING BETWEEN 1 AND 24 ATOMS OF CARBON OR A GROUP OF THE GENERAL FORMULA (III) IN WHICH R5 IS AN ALKYLENE GROUP THAT CONTAINS BETWEEN 2 AND 8 ATOMS OF CARBON, AND R2 AND R3 ARE AS THEY HAVE BEEN DEFINED PREVIOUSLY, EACH R4 IS INDEPENDENTLY A RENTING GROUP BETWEEN 2 AND 8 CARBON ATOMS, AND EACH X, YYZ IS INDEPENDENTLY AN INTEGER BETWEEN 0 AND 20. IN A CONFORMATION, COMPONENTS (A) AND (B) ARE PRESENT IN ENOUGH AMOUNTS TO SUPPLY A TOTAL CLEANING OF THE INTAKE SYSTEM. IN ANOTHER CONFORMATION, COMPONENTS (A) AND (B) ARE PRESENT IN ENOUGH AMOUNTS TO AVOID OR REDUCE THE FORMATION OF DEPOSITS IN THE INTAKE VALVES OR TO SEPARATE THEM WHEN THEY HAVE ALREADY FORMED. METHODS ARE ALSO PRESENTED TO PROVIDE A TOTAL CLEANING OF THE INTAKE SYSTEM AND TO AVOID OR REDUCE THE FORMATION OF DEPOSITS IN THE INTAKE VALVES OR TO SEPARATE THEM.
