World is suffering with continuous crises of energy demand, hike in its price, and depletion of fossil fuels. Largely used one of the fossil fuel is diesel is used for transportation, for locomotives, and all types of CI engines, but all countries aren’t fulfill with diesel fuel and they import their fuel from other countries like UAE, East Asia and some European countries. India is one of the country which consumes 3.7 mb/day of crude oil out of which 70 % of crude oil was import by other countries, it directly affects the growth of economy of India. The alternative for diesel fuel was comes out is an Biodiesel (Methyl Ester) which is defined as per ASTM standards is, long chain of mono alkyl ester obtained by fatty acids which prepared from renewable resources. Biodiesel has obtained from vegetable oils by ‘Transesterification Process’ that have been considered as a promising alternate fuel. The researches regarding blend of diesel and single biodiesel have been done already. But very few researches are done with combination of two biodiesels, so it shows lots of scope for research in this area. In this research work we took combination of two biodiesels prepared from thumba and waste fried oil. Firstly we prepared biodiesel from waste fried oil which is easily available in the hotels and restaurants at very cheap cost so that we can easily overcome cost issue. The second biodiesel was prepared from thumba which is non edible vegetable oil plant, mainly grows in rain fed parts of Rajasthan and Gujarat. We firstly mix the both biodiesels and then prepare blends of them with pure diesel in the various ratios of B09, B18, B27, and B36. Testing of hybrid methyl ester is taken on single cylinder VCR CI without any modification in hardware of engine with two compression ratios of 16 and 18. By putting biofuel in engine works without any disturbance in working of the single cylinder engine and results are as below.
