Effects of enhanced fuel with Mg-doped Fe3O4 nanoparticles on combustion of a compression ignition engine: Influence of Mg cation concentration

The present study focuses on the synthesis of novel catalytic nanoparticles and their effect combustion, performance, emission characteristics a diesel engine. For this purpose, Mg cations were doped into Fe3O4 lattice to form MgxFe(3-x)O4 (x = 0.25, 0.5, 0.75, 1) using solution combustion method. Comprehensive characterization studies carried out assess oxygen storage capacity (OSC) properties final powders. These synthesized samples dispersed in diesel-biodiesel blend fuel with concentration 90 ppm. Assessment structure proved formation MgFe2O4 structures, suggesting that embedded formed appropriate structures. OSC was reduced from 8661 ?mol/g (Mg0·25Fe2·75O4) 7069 (MgFe2O4) by introducing additional cations. When run six-cylinder engine, mixed did not significantly influence indicated power (IP), brake specific consumption (BSFC) or thermal efficiency (BTE). In addition obtained result for sample, which declined increasing lattice, sample highest cations, considerable reduction detected major exhaust emissions such as HC (56.5%), PM1 (35%), PN (37%) slight decrease occurred CO (7%) compared engine fueled pure fuel. Based experimental results, can be considered useful nanocatalyst mixing fuels reduction.
