Study Of Optimum Parameters In Enhancing The Performance Of VCR Engine Using Taguchi Method

Biofuels are in present days are known commonly to the peoples which is considered to be as alternative fuel to the various types of engines in automobile sectors. The commonly used engine is variable compression ratio engine which is available in market. The fuel type is diesel. Moreover, to run the engine using alternative fuel has made challenging to researcher in present scenario, due to depletion of traditional fuel i.e. fossil fuel. In the present work biofuel namely turmeric leaf oil (TLO) with various percentages of blends is used in VCR engine along with traditional fuel to evaluate the performance based on their output parameters like brake thermal efficiency and volumetric efficiency and their emissions from the exhaust. The blend with various percentages like B70 (i.e. 70% diesel and 30% turmeric leaf oil), B60 (i.e. 60% diesel and 40% TLO) and B50 (i.e. 50% diesel and 50% of TLO) were considered in the present work. As the type of engine is variable compression ratio, therefore three compression ratios are considering i.e. 17.5:1, 18.5:1 and 19.5:1, by maintain constant speed rate of 1500rpm in the current work. The finding reveals that 19.5:1 compression and B70 has performed better when compared with other ratios and blends. The performance is determined based on the load applied on the VCR engine
