Alcohol Blends for Experimental Investigation of Noise Emission and Deposit Accumulations in Diesel Engine
Main Article Content
Abstract
In this experimental study, three fuel samples—PD100, D95Bu5 (95%vol. diesel Bu5%vol. N-butanol), and D95Pn5 (96%vol. diesel, 4%vol. N-pentanol)—were tested for endurance in a single-cylinder CI engine as part of this inquiry. The study's findings demonstrated that small deposits on the engine head were visible upon visual inspection of all gasoline samples tested. Compared to the engine running with DF, the D95Bu5 engine exhibited more carbon deposits on and around the engine head surface, according to SEM examinations. However, the binary mix D95Pn5 showed less carbon accumulation. At the moment, fuel blends were made from residual diesel, n-butanol and n-pentanol. When compared to DF, the deposit concentration was reduced by emulsion fuel in the binary blend, even when n-pentanol was added as blend D95Pn5 for aluminum (Al), calcium (Ca), and cadmium (Cd). Concentrations were further reduced.
