Two blends were prepared by volume by mixing isopropyl alcohol and diesel fuels directly. The blends created were 25% isopropyl alcohol-75% (IPA25) diesel; 35% Isopropyl alcohol-65% diesel (IPA35). The blends were kept undisturbed for about a week and then various properties test were done over the test as mentioned in table 5. A single cylinder Marshal diesel engine was used with a Marshal AC generator was used to which a load bank was connected via multimeter for variating loads and study the current and voltage readings.
The specification DI marshal engine is shown in table 3. A measuring cylinder was used to store the blend and to pass the fuel towards the filter. The experiment was conducted at three different load conditions that are idle state (no load), medium load(1200W) and peak load(2400W). The test was done for 10 minutes on each load with every blend and the fuel consumption was measured with the help of measuring cylinder for ten minutes and an average was taken for determining fuel consumption rate.An AVL exhaust gas analyser was used for measuring the NOx, CO, CO2 and HC emissions over different load condition and for both the blends and 100 % diesel as well. The specifications of AVL gas analyser are shown in table 4.the Fig 1 shows the setup used in this experiment.TABLE 2: Specifications of AC Generator:POWER OUTPUT (KW)3.5RPM1500VOLTS230/415PHASE1AMPS10FREQUENCY (Hz)50TABLE 3: Specifications of DI marshal engine:RATED POWER (BHP)5.0RATED SPEED (RPM)1500BORE (mm)80STROKE (mm)110NO OF CYLINDER1CUBIC CAPACITY (cc)555COMPRESSION RATIO16.5:1TORQUE AT FLYWHEEL END (Kg-m)2.39TORQUE AT CAMGEAR END (Kg-m)7.78SFC (g/Kwh)250ENGINE BARE WEIGHT (Kg)163GRADE OF OILSAE 30/40TABLE 4: Specifications of Exhaust gas analyser: AVL DIGAS 444Measured parameterRangeResolutionCarbon Monoxide0-10%.01%volCarbon Dioxide0-20%.01%volHydrocarbons0-20000ppm1 ppmNOx0-5000ppm1 ppmEngine Speed400-6000rpm1 rpm
