Effect of compression ratio on a single cylinder diesel engine operated with Ternary fuel

The objective of this research is to evaluate the characteristics of an engine by using diesel-biodiesel-ethanol (Ternary fuel) into the present VCR (Variable Compression Ratio) single-cylinder four-stroke water-cooled diesel engine. In this investigation, palm oil is taken as biodiesel. The world needs biodiesel due to the deficiency of fossil fuels. The best choice is selecting the biodiesel and ethanol because they are available from the renewable feedstock, non-toxicity to the environment and it is eco-friendly. In blending stage B30 as a blend chosen because it contains 70% of diesel, 20% of biodiesel as palm oil and lastly remaining 10% is ethanol was used. 0 kW which is known as a no-load condition, 3 kW, 6 kW and 9 kW were taken as loading conditions. In these loading conditions 9 kW taken as maximum load condition. The present investigation is to measure together with these parameters emissions like Hydro Carbons (HC), Carbon monoxide (CO), Carbon dioxide (CO2), Oxides of nitrogen (NO) and smoke were taken. 15:1, 16.5:1, 17.5:1 and 18:1 are the four compression ratios selected to find the engine emission characteristics.
