    Experimental analysis of cardanol biofuel as an alternative fuel for diesel engines with air-side oxygen enrichment
    (Trans Tech Publications Ltd ttp@transtec.ch, 2014) Dinesha, P.; Nayak, V.; Kumar, D.; Mohanan, P.
    The present study investigates the effect of air-side oxygen concentration enrichment on the performance and emission of a single cylinder diesel engine using a bio-fuel blend as fuel. In this study, a natural phenolic compound, namely, cardanol is selected as the bio-fuel, which is obtained from the shell of cashew nut after purification. A blend of B10M10 (10% cardanol +10% methanol + 80% diesel by volume) is prepared and tested in the engine at various loading conditions. The experiments are carried out at atmospheric oxygen condition and an increment of 3, 5, and 7% of atmospheric oxygen concentration by weight. There is a drastic reduction in HC, CO, and smoke except for NOx emission. The level of NOx emission increases as the oxygen concentration in the intake air is increased. The performance characteristic will increase as the oxygen concentration increases, and higher brake thermal efficiency is obtained for B10M10 at 7% oxygen concentration. B10M10 with 7% oxygen enrichment gives better results, similar to diesel, except for NOx emission. © (2014) Trans Tech Publications, Switzerland.

    Thermal barrier coating for diesel engine application - A review
    (Elsevier Ltd, 2020) Godiganur, V.S.; Nayaka, S.; Kumar, G.N.
    In the current world scenario with the threat of global warming, diesel engines have to more efficient than ever to avoid the situation to be even worse. Thermal barrier coating (TBC) may be successful in making diesel engines more efficient. TBCs are proven to be performing well in gas turbines and used widely in that application. TBCs in a diesel engine are exposed to a slightly different environment in comparison with gas turbines. Different bond coat and top coat materials that can be used in relatively low-temperature application such as diesel engine. A simplified review is done on durability and reliability aspects like residual stress, thermal cycling performance, thermal conductivity, and thermal reflectance is done in this paper. © 2020 Elsevier Ltd.
