ABSTRACT:
Accumulation of carbonaceous deposits on the combustion chamber surfaces of internal combustion engines is responsible for increased fuel octane requirement to prevent knock. Treatment of these carbonaceous deposits with weak bases, such as aqueous ethylenediamine, aids in their removal and thereby reduces the octane requirement of an internal combustion engine. The method is also applicable for removal of carbonaceous deposits from metal surfaces generally.
