THE EFFECT OF REDUCTION OF GASOLINE LEAD CONTENT ON ROAD ANTI-KNOCK PERFORMANCE

A STUDY OF THE EFFECT OF FUEL CONTAINING LEAD AT VARIOUS CONCENTRATIONS (O-O.7G PB/LITRE) ON THE ANTI-KNOCK PERFORMANCE OF CAR ENGINES IS DESCRIBED. THE WORK WAS CONDUCTED IN TWO WAYS: (1) BY OCTANE REQUIREMENTS SURVEYS IN WHICH A LIMITED NUMBER OF FUEL SERIES WAS TESTED IN A WIDE RANGE OF CARS; (2) BY DETERMINING THE ANTI-KNOCK BEHAVIOUR OF A WIDE RANGE OF FUEL COMPOSITIONS IN SELECTED CARS AT HIGH AND LOW ENGINE SPEEDS. IT IS DEMONSTRATED THAT, FOR A GIVEN LEVEL OF RESEARCH OCTANE NUMBER, A REDUCTION IN FUEL LEAD CONTENT GENERALLY RESULTS IN REDUCED ROAD ANTI-KNOCK PERFORMANCE. SOME ADDITIONAL COMMENT IS MADE ON ENGINE PERFORMANCE, THERMAL EFFICIENCY, AND EFFECT ON EXHAUST EMISSION LEVELS, CONSEQUENT UPON THE USE OF FUEL WITH REDUCED LEAD CONTENT. /AUTHOR/
