Impact Of Compression Ratio In The Emission And Performance Phenomenon Of A Ci Engine Fuelled With Jojoba Biodiesel Blends

In the present experimental investigation, jojoba biodiesel-diesel bends were fuelled to a four stroke single cylinder compression ignition engine at compression ratio of 17.5 to understand its emission and performance phenomenon. Jojoba biodiesel was prepared through base catalysed transesterification process using NaOH and methanol. The physio-chemical properties like calorific value, kinematic viscosity, density, flash and fire point were determined and found to be within ASTM standards. The performance parameters includes brake thermal efficiency, brake specific fuel consumption and emission parameters includes unburned hydrocarbon, carbon monoxide, oxides of nitrogen and smoke were assessed. Optimal operating parameters of the engine was analyzed by incrementing and decrementing the compression ratio upto CR18 and CR17 respectively. (C) 2019 Elsevier Ltd. All rights reserved.
