The effects of amorphous boron (AB) hybrid particles decorated with lanthanum orthoferrite particles on the combustion behavior and emission performance of conventional fuels were investigated. They are produced by combining ball-milling amorphous boron particles (AB/BM), Fe3O4 (F2) ferrite produced by sol–gel technique and La0.75Fe1.25O3 (LAF2) and LaFeO3 (LAF3) lanthanum ferrite nanoparticles by an ultrasonication technique. At 2.5 wt% (17353 ppm) particle load, the highest maximum flame temperature of gasoline-based nanofluid droplets was 644 K for AB-B.M., while at 7.5 wt% (52059 ppm) concentrations, the maximum aggregate temperatures were 642 K, 1358 K and 1298 K in the presence of nanohybrid structures based on AB-B.M., AB/LAF2 and AB/LAF3, respectively. At 2.5 wt% concentrations the lowest extinction time was recorded as 1321 ms for fuel droplets containing AB/LAF2 particles and at 7.5 wt% concentrations 1565 ms in the presence of AB-BM particles. According to the diesel engine test results, AB/LAF2 particulates have a 15 % and 17.6 % reduction in HRR compared to D100 at 15 Nm and 45 Nm respectively, and the largest reduction in BSFC values is 8.38 % and 7.99 % respectively at the same loads. At 60 Nm the highest decrease in CO emissions was 0.01 % in the presence of AB/LAF2 particles. The lowest HC emissions were observed in the presence of AB/LAF2 particulates, with 61.7 %, 42.85 %, 30.43 % and 41.37 % reduction in HC emissions compared to pure diesel at 15 Nm, 30 Nm, 45 Nm and 60 Nm respectively. At 30Nm, 45Nm and 60Nm, the lowest NOx emissions were recorded for the D100 + 250AB/LAF2 fuel, with reductions of 6.71 %, 9.33 % and 12.59 % respectively compared to D100.
