Abstract

"ADITIVOS PARA COMPOSIçõES DE COMBUSTìVEIS, A FIM DE REDUZIR FORMAçãO DE DEPóSITOS EM CâMARAS DE COMBUSTãO". A presente invenção refere-se a um método para reduzir a formação de depósitos na câmara de combustão em um motor usando um modificador de atrito para combustíveis. O modificador de atrito é preparado combinando um ácido carboxílico saturado e uma amina alquilada ou alcoxilada. A seleção específica do modificador de atrito permite que um concentrado estável de aditivos seja formulado, proporcionando uma diminuição significativa em CCD, sem aumentar a incidência de IVD em motores de combustão que funcionam com um combustível modificado com o concentrado de aditivos.
