Development of a Laboratory Test for Multiport Fuel Injector Deposits - Evaluation of the Jet Fuel Thermal Oxidation Test Apparatus (JFTOT)

Abstract

This report describes the laboratory effort to develop a bench test suitable for screening gasolines to determine their potential for forming deposits in automative port fuel injectors. The test selected for this work was the Jet Fuel Thermal Oxidation Test (JFTOT) method described in ASTM D 3241. Tests were conducted at various temperatures and operating conditions on two base gasolines having low and high deposit forming tendency in vehicle tests. In addition, tests were also run on a commercial unleaded gasoline containing detergent additives and on the high deposition fuel treated with varying dosages of four additives claimed to be effective in preventing port fuel injector deposits in vehicle tests.
