Abstract
Rapid development of the global economy demands huge amount of Energy. Transportation sector contributes major part of economy development. Fossil fuels like Petrol and Diesel are used for transportation and heavy duty vehicles. Higher rate of consumption of these naturally available fuels leads to its depletion and deterioration of environment. To solve such issue many researchers are interested in identifying and using alternative fuels for internal combustion engines. Biodiesel is renewable fuel and can be used as alternative fuel for Diesel engines. In present work Canola oil based Biodiesel (COB) is blended in Diesel with different concentration like B20, B40 and B60. Engine input variables like compression ratio (13:1, 15:1, 17:1) and load (4, 8,12kg) are considered to optimize the results. The Performance of Variable Compression Ratio (VCR) Diesel Engine is evaluated using Taguchi method. Analysis of variance is conducted to recognise the significance of input variables on Brake Thermal Efficiency, Brake power Specific Fuel Consumption. Results of optimization showed that load is the most crucial factor which affects the engine performance i.e. Increase in load decrease the Brake Thermal Efficiency, Brake Power and increases the Specific Fuel Consumption.
Highlights
Alternative or non-conventional fuels, are the combustibles material and can be used as fuels like conventional fuels, like fossil fuels [1]
Maximum value of Delta is for load i.e. 9.3393 having rank 1 and minimum i.e. 0.0601 for Compression ratio having rank 3, it means Load is having maximum and compression ratio is having minimum effect of on Brake Power [31] this result can be confirmed with S/N ratio and Analysis of variance (ANOVA) [32, 33]
Maximum value of Delta is for load i.e. 4.11 having rank 1 and minimum i.e. 2.38 for Blend having rank 3, it means Load is having maximum and blend is having minimum effect of on Brake Thermal Efficiency this result can be confirmed with S/N ratio and ANOVA
Summary
Alternative or non-conventional fuels, are the combustibles material and can be used as fuels like conventional fuels, like fossil fuels [1]. Bio fuels are derived from biomass i.e. plant material or animal waste. Biodiesels possess similar characteristics as compared to conventional Diesel. Soybean oil [8, 9], corn oil [10, 11], sunflower oil [12], rapeseed oil [13, 14] and palm oil [15, 16], algae [17, 18], Jatropha [19, 20] are other major resources of biodiesel worldwide. Recycled grease [21, 22], oils [23] as well as animal fats [24] can be used for production of biodiesel. In present work Canola Oil Based Biodiesel (COB) is considered because canola seeds production is in greater amount than other oil seed crops, leading to increased canola oil production.
