The Effects of an Increase in the Concentration of Ethylene Dibromide in a Leaded Fuel on Lead Deposition, Corrosion of Exhaust Valves and Knock-Limited Power

Abstract

Tests were conducted to determine if an excess of ethylene dibromide might decrease the amount of unscavenged lead in the cylinder and thereby reduce valve-crown corrosion. When ethylene dibromide in excess of the amount theoretically required to combine with lead in the fuel (1-T mix) is added, corrosion of the exhaust-valve-crown corrosion and material deposits on piston and spark plugs were reduced. Fuel containing twice the theoretical amount of ethylene dibromide (2-T-mix) produced the same knock-limited indicated mean effective pressure as did fuel containing the theoretical amount of ethylene dibromide (1-T mix).
