Abstract: In this study the performance and emissions tests were conducted on a single-cylinder3.5kW diesel engine using a non-edible plant-based bio-fuel Cardanol produced from cashew nut shell liquid (CNSL) blend with Hongeand diesel. The bio-fuel blends 5C10H85D (5% cardanol+10% Honge+85% diesel),10C10H80D, (10% cardanol+10% Honge +80% Diesel) 15C10H75D (15% cardanol +10% Honge + 75% Diesel) and 20C10H70D (20% cardanol+10% Honge+70% diesel) were prepared and tested at various loads (0%,25%, 50%, 75% and full load conditions) and compared with baseline diesel at 300 bar, 400 bar and 500 bar injection pressure and 18:1 compression ratio. The experimental results show that at full load, the brake thermal efficiency of 10C10H80D is 28.78% comparatively similar to that of diesel is 29.75%. The lower emissions of CO, hydrocarbon except NOx are encouraging to recognize 20C10H70D as an optimized fuel blend for a compression ignition engine. The significant factors of cardanol bio-fuel include its low cost, non-edible, abundance, and it is a by-product of the cashew nut industries.

I. INTRODUCTION
The creating economy combined with population development has added to an exponential interest for energy sources. The disappointment of oil based goods to meet these proceeded with essential demands and pollution related issues as a result of far reaching usage of non-renewable sustainable power sources have required the advancement and the adjustment of inexhaustible and eco-pleasing fuel communicated by Kulkarni BM et.al (2008). Increasing familiarity with the utilization of non- renewable energy resources similarly as their negative characteristic impact has actuated excitement for the potential benefits of biofuels, for example, biodiesel, which is a substitute fuel for diesel engines revealed by Pullen and Saeed (2011). Vegetable oils contain many fatty acids. Four fatty acids, namely palmitic, stearic, oleic and linoleic acids, present in higher compositions. The variation of fatty acid content in the biofuel affects the performance and emissions in a compression ignition (CI) engine reported by Dinesh (2017).
