EXPERIMENTAL VALIDATION OF A 3-COMPONENT SURROGATE FOR SASOL-IPK IN SINGLE CYLINDER DIESEL ENGINE AND IQT

摘要

The goal of this investigation is to compare the validation of Sasol-IPK and its surrogate fuel in the IQT and in an actual diesel engine. The surrogate fuel is composed of three components (46% iso-cetane, 44% decalin and 10% n-nonane on a volume basis). IQT experiments were conducted as per ASTM D6890-10a. Engine experiments were conducted at 1500 RPM, two engine loads, and two injection timings. Analysis of the ignition delay, peak pressure, peak RHR and other combustion phasing parameters, showed a closer match in IQT than in the diesel engine. This investigation suggests that validation in a single cylinder diesel engine should be a part of the surrogate validation, particularly for low ignition quality fuels.
