Abstract

Abstract
A number of reports prove a negative influence of deposits accumulated on critical sites in an engine. It is known that deposits in engines increase octane requirement, emission of harmful exhaust gases, and fuel consumption. As a consequence of problems caused by deposits in engines, the ACEA issued a recommendation which requires 9 as a minimum rating for the cleanness of intake valves.
By using multipurpose additives the tendency of fuels to form deposits in engines is controlled more or less successfully. Thus, the proper selection of multipurpose additives is a prerequisite for competitiveness of motor gasoline.
The paper presents the results of efficiency tests of multipurpose additives made by regard of the issue of optimum additive selection.
