Abstract: The present invention relates to the use of at least one, optionally alkylated diarylamine in a fuel or a fuel additive for cleaning the combustion chamber of an internal combustion engine, in particular of a motor vehicle engine. A further aspect relates to a method for cleaning the combustion chamber of an internal combustion engine during the operation of the internal combustion engine by burning a fuel, wherein the fuel contains a fuel additive comprising at least one, optionally alkylated diarylamine.

Abstract: In the Taylor reactor, in accordance with a first alternative of the invention, the reactor housing and/or the rotor are/is equipped such that the cross section of the reaction volume initially rises from the inlet to the outlet but the rise in cross section decreases in the direction of the outlet at least over part of the length of the rotor. In accordance with a second alternative of the invention, which may also find application in addition to the first, the end face of the rotor is designed in such a way that the reaction volume opens out into the outlet in such a way that it is at least substantially free from deadspaces (FIG. 4).
