Abstract

ABSTRACT The wear of fuel injection system which supplies fuel to CI engine plays a dominant role on combustion behaviour of fuels as well as on exhaust emission. Certain amount of fuel lubricity is required for mitigation of wear of these components. A simple laboratory test was devised using ball on disc machine. Various diesel fuels and n-cetane were evaluated. The paper describes a laboratory test method for assessing lubricity characteristics of fuels and compares its operating parameters with ASTM D-5001 BOCLE test. It also discuss the effect of sulphur and fuel lubricity additive on wear.
