In this experimental investigation, the performance, combustion and emission characteristics of a HCCI (Homogeneous Charge Compression Ignition) engine are analyzed using various biodiesel blends such as B10, B20, B30, B10A30, B20A30 and B30A30 respectively. The alumina (Al2O3) nanoparticles of 30 ppm are mixed with the various prepared fuel blends by using an ultrasonicator which would help to fetch a uniform suspension of nanoparticles over the blend fuel. The prepared samples of biodiesel were tested for its chemical composition by using GCMS method. SEM analysis and X-ray diffraction have been done for the alumina nanoparticles to test the size of the particles that are blended to the biodiesel blends. The chemical reactivity and rate of mixing are better though the characteristics of nanoparticles exhibit high surface area/volume ratio during the combustion, which ultimately results in good performance and emission characteristics in the diesel engine. Among the test fuels, B10A30 shows better performance both in terms of efficiency and emissions such as HC, CO, NOx and Smoke.
