Di Diesel Engine

A numerical study of NOx reduction for a Direct Injection (DI) Diesel engine with complex geometry, which includes intake/exhaust ports and moving valves, was carried out using the commercial computational fluid dynamics software KIVA-3v. The numerical simulations were conducted to investigate the effects of engine operating and geometrical parameters, including fuel injection timing, fuel injection duration, and piston bowl depth, on the NOx formation and the thermal efficiency of the DI Diesel engine. The tradeoff relationships between the reduction in NOx and the decrease in thermal efficiency were established.

Di Diesel Engine

Environmental contamination has been increasing day by day due to increase in use of fossil fuel, therefore world is moving towards unconventional sources of energy generation. In this study, a diesel engine characteristic was analysed in a single cylinder, four strokes, water cooled, direction injection (DI) diesel engine by using two different fuel blends, one is non-edible oil (Moringa oleifera) and another one is alcohol (Ethanol) and operating at different engine load. Diesel engine characteristics were examined in terms of engine performance, emission and combustion characteristics by using Diesel-RK software and before that validate the numerical result with experimental result. The result shows that MB20 has reduction of 2.26%, 7.37%, 2.6%, 8.3% and 15.02% in BTE, EGT, Smoke emission, MRPR and NOX respectively and increases 8.9% and 12.34% in SFC and CO2 emission. The MBE20 has increased by 2.9% and 18.75% in SFC and CO2 emissions and decrease of 1.25%, 2.45, 5.44%, and 3.06% in BTE, EGT, MRPR and NOX respectively was found as compare to diesel fuel. In this paper, mixing various blends 20% of Moringa Oleifera biodiesel fuel with 20% of ethanol gives optimum blends ratio.
