SOFTWARE THE WINDOWS® -BASED INTERFACE PERMITS MANUAL AS WELL AS AUTOMATED OPERATION THROUGH KEYBOARD OR MOUSE INPUT. FOR SPECIFIC RESEARCH OBJECTIVES TEST CONDITIONS CAN BE VARIED TO SIMULATE ACTUAL ENGINE OPERATION - FROM COLD STARTING TO HIGH SPEED CONDITIONS. COMBINED WITH ITS LOW FUEL VOLUMETRIC REQUIREMENT (ABSOLUTE MINIMUM OF 15 ML) THE IQT IS A CAPABLE FULLY AUTOMATED TOOL FOR USE IN LABORATORY REFINERY AND PILOT PLANT APPLICATIONS WHERE CANDIDATE FUELS CAN ONLY BE PRODUCED IN SMALL QUANTITIES. BASE UNIT DIMENSIONS 56 CM (22 IN) H X 74 CM (29 IN) W X 36 CM (14 IN) D. BASE UNIT WEIGHT APPROX. 68 KG (150 LBS) POWER REQUIREMENT 20A 240VAC 50/60 HZ PROTECTED BY AN UNINTERRUPTIBLE POWER SUPPLY (UPS) AIR SUPPLY COMPRESSED AIR 20.9 % O2 ±1.0 % REGULATED MINIMUM: 21.7 BAR (310 PSI) - COMBUSTION PROCESS 12.1 BAR (175 PSI) - INJECTION PROCESS NITROGEN SUPPLY COMPRESSED NITROGEN INDUSTRIAL GRADE REGULATED MINIMUM: 3.5 BAR (50 PSI) - FUEL FEED PROCESS COOLING SYSTEM CLOSED-LOOP LIQUID TO AIR COOLING SYSTEM FUEL INJECTION SYSTEM (PATENTED) PINTLE-TYPE SINGLE HOLE NOZZLE WITH AIR-DRIVEN FUEL INJECTION PUMP. THE IGNITION QUALITY TESTER (IQT) IS A BENCH-SCALE CONSTANT-VOLUME COMBUSTION DEVICE WITH A SPRAY INJECTION SYSTEM DESIGNED FOR THE DIRECT MEASUREMENT OF THE IGNITION DELAY OF LIQUID FUELS. IGNITION DELAY IS THEN USED TO CALCULATE A DERIVED CETANE NUMBER (DCN) USING THE ASTM D6890-08 METHOD WITH HIGH REPEATABILITY (±0.85 DCN 34-61 DCN RANGE) PROVIDING HIGH SENSITIVITY FOR MIDDLE DISTILLATE FUELS. A PIEZO-ELECTRIC PRESSURE TRANSDUCER INSTALLED IN THE COMBUSTION CHAMBER MEASURES THE PRESSURE RISE DURING THE COMBUSTION EVENT; THE TIME DELAY BETWEEN THE START OF INJECTION (SOI) AND THE RISE IN COMBUSTION PRESSURE TO THE COMBUSTION PRESSURE RECOVERY POINT OF INJECTED FUEL DETERMINES THE IGNITION DELAY FOR VARIOUS FUELS THE IGNITION DELAY COMPRISES BOTH PHYSICAL PROCESSES (E.G. SPRAY BREAKUP VAPORIZATION AIR ENTRAINMENT) AND THE CHEMICAL KINETICS OF IGNITION. A PNEUMATICALLY DRIVEN MECHANICAL FUEL PUMP IS USED FOR THE INJECTION OF THE FUEL ALONG WITH A SINGLE-HOLE S-TYPE DELAYED (INWARD OPENING) PINTLE NOZZLE. THE INJECTION PRESSURE AS EXPERIMENTALLY DETERMINED IS APPROXIMATELY 225 BAR DURING THE MAIN INJECTION PERIOD; N-HEPTANE (?99.5% FLUKA) IS USED FOR ALL EXPERIMENTS IN THIS STUDY AND IS CHOSEN BECAUSE OF ITS USE AS A CALIBRATION FUEL FOR THE IQT WITH A REFERENCE IGNITION DELAY TIME OF 3.78 MS.
