Abstract:

This paper investigates the effect of a cetane improver on the autoignition characteristics of Sasol IPK in the combustion chamber of the Ignition Quality Tester IQT. The fuel tested was Sasol IPK with a Derived Cetane Number DCN of 31, treated with different percentages of Lubrizol 8090 cetane improver ranging from 0.1 to 0.4. Tests were conducted under steady state conditions at a constant charging pressure of 21 bar. The charge air temperature before fuel injection varied from 778 to 848 K. Accordingly, all the tests were conducted under a constant charge density. The rate of heat release was calculated and analyzed in details, particularly during the autoignition period.
