Effects of ethanol–diesel fuel blends on the performance and exhaust emissions of heavy duty DI diesel engine

An organic compound, Dioxane, is blended to reduce the viscosity of raw vegetable oil (Mahua). A dilute blend was prepared by mixing with raw vegetable oil (Mahua) and 10% dioxane in volume basis. Tests were conducted on a single cylinder, water cooled, DI diesel engine coupled with the eddy current dynamometer. Emissions like HC, NOX, etc., were measured by using gas analyzer and smoke density was measured by using smoke meter. The cylinder pressure, heat release rate were measured by combustion analyzer. From the experimental investigation, it was observed that operating at a blend ratio of 10% diesel-80% mahua oil-10% Dioxane significantly reduced the HC and NOx emissions when compared to diesel fuel. It was also observed, the variation of break thermal efficiency is almost same to that of diesel fuel. Hence, it can be concluded that raw vegetable oil (mahua) with Dioxane blend could partially replace the diesel, as a fuel.

Di Diesel Engine

Utilization of oxygenated fuels has proven to be able to significantly control diesel engine exhaust emissions. Presented in this paper is a new oxygenated fuel di-(2-methoxypropyl) carbonate (DMPC), which was produced through transesterification reaction using dimethyl carbonate (DMC) and propylene glycol monomethyl ether (PGMME) as reactants as well as potassium hydroxide (KOH) as catalyst. Its structure characterization was completed through analyses with Fourier transform infrared (FT-IR), 1H nuclear magnetic resonance (NMR), and GC-MS analytical techniques. Further study was made about the effect of the oxygenate addition to diesel fuel on chemicophysical properties, combustion performances, and exhaust emissions characteristics. Experimental results displayed that the oxygenated fuel is mutually soluble with diesel fuel in any proportion at ambient temperature around 25 °C. With DMPC introduced to diesel fuel, kinematic viscosity decreases linearly, smoke point increases linearly, and flash point declines remarkably even under low content 5 vol %. Results of combustion test carried out on a single cylinder, DI diesel engine running at 1600 rpm and 2000 rpm showed that CO can be reduced by up to 60.0%, smoke can be lessened by up to 90.2%, while NOx increases by 4.4–14.0% as 15 vol % and 25 vol % of the oxygenate was added to a diesel fuel. Engine in-cylinder peak pressure increases somewhat and ignition delay duration becomes a little shorter. Both engine in-cylinder pressure rising rate and heat release rate increase noticeably during the premixed combustion.
