AB  - Compression ignition engines powered by diesel are the work horses of developing 
      countries like India. However, burning fossil fuel causes a lot of air pollution 
      and the depletion of fuel at an alarming rate. Fuels produced from biomass or 
      wastes can partially substitute fossil diesel to decrease its consumption. One 
      such feedstock is waste cooking oil (WCO) which can be easily converted into fuel 
      for diesel engines. The hydrotreating process stands out among the methods 
      available for converting WCO into fuel, since its properties are almost similar 
      to fossil diesel with little or no oxygen content. In this study, the 
      physico-chemical properties of the hydrotreated waste cooking oil (HVO), 
      biodiesel of waste cooking oil, diesel and blends of HVO and diesel are compared. 
      The blends were prepared by mixing 10%, 20%, 30%, 40% and 50% of HVO on volume 
      basis in diesel. The evaporation rate and ignition probability of the fuel 
      samples were found by using a hot-plate test setup. HVO had higher ignition 
      probability than all the test sample. As the percentage of HVO increased in the 
      test samples, the ignition probability increased. The Sauter mean diameter (SMD) 
      of the samples was also found using Malvern Spraytec. The SMD of HVO was larger 
      than diesel but smaller than biodiesel. The study shows that blends of HVO up to 
      30% are feasible for present use in diesel engines, as the viscosity (2.54, 2.59 
      and 2.62cSt) and calorific value (42.41, 42.29, 42.08 MJ/kg) of the three blends 
      (10%, 20% and 30%) is close to diesel (2.51cSt and 42.58 MJ/kg). Also, due to 
      high cetane index, neat HVO or blends having higher HVO content (> 30%) cannot be 
      used in the existing engines as the engine power output may be affected. 
      Therefore, to use these fuels, the engine needs to be modified which is not 
      feasible for existing engines. The FTIR and GC-MS analysis shows that the HVO has 
      low oxygen content and high amount of paraffins, whereas biodiesel of waste 
      cooking oil has high unsaturation and high oxygen content.
