Ethanol–biodiesel–diesel Blends as a Diesel Extender Option on Compression Ignition Engines

Abstract

Increasing fuel demand, decreasing natural reserves and environmental consciousness have together led to testing and implementing new fuels and blending components of compression ignition engines. Biofuels are very commonly added to fossil fuels, mostly ethanol to gasoline and FAME to diesel. Harmonizing their properties with engines is a great challenge for automotive and oil industry. Increasing demand for diesel oil in Europe raised the question about the possibility of increasing the amount of bio extenders. There were and certainly there are a number of experiments aimed at substituting or blending diesel with other fuels. One group of such fuels makes bioethanol– biodiesel–diesel oil mixtures. The paper proposes a global overview on literature and presents the obtained results. The article explores the possibility of using bioethanol–biodiesel–diesel oil mixtures in vehicles and agricultural compression ignition engines. The main aspect of researches was to find blends substitutable for compression ignition engines. Investigations were made to determine the maximum volume of a renewable part thus reaching the same or similar power output with lowering emissions. The received results were used for environmental and economical investigations. The valorisation of the results shows that bioethanol–biodiesel–diesel blends fulfil the cetane number, viscosity and lubricity requirements for standard diesel. Practical measurements and engine tests show that the utilization of a new fuel decreases emissions from the engine. The results of agricultural feedstock calculation indicate that in Hungary the biofuel part of the investigated fuels can be produced from an overflow.

An analysis of noise pollution emitted by moving MF285 Tractor using different mixtures of biodiesel, bioethanol and diesel through artificial intelligence

“…29,30 vibrations are increased per unit of time, thereby causing more noise pollution. This finding was consistent with the results of studies conducted by Taghi Zadeh-Ali Aaraei et al 34 and Zoldy 35 (see Figure 6). In Figure 6, it is shown that a change in the percentage of bioethanol in fuel mixtures on average led to little change in noise pollution at various revolutions, whereas the noise pollution emitted in the third gear was more than that in the second gear.…”

The Impact of Biodiesel Fuel on Ethanol/Diesel Blends

“…Therefore, biodiesel fuel was used to compensate the decrease in the aforesaid two properties [16]. The impact of biodiesel fuel on the CN of ethanol-diesel blends was predicted using the formula suggested in [46]. The CN of pure diesel fuel (CN D ) was predicted using the formula suggested in [47], as follows:…”

Fuel Properties of Butanol – Hydrogenated Vegetable Oil Blends as a Diesel Extender Option for Internal Combustion Engines

“…In these, the biodiesel helps blend ethanol with diesel as it acts as an emulsifier. Results of numerous investigations, [13][14][15][16] showed that the bioethanol-biodiesel-diesel blends fulfil the cetane number, viscosity and lubricity requirements for standard diesel. The practical measurement, the engine bench tests showed that utilization of the new fuel decreases the emissions of the engine.…”

“…The brake-specific fuel consumption increases with the addition of alcohol. Alcohol fuels contain oxygen, so this will improve combustion, but power decreases due to lower calorific value compared with diesel, so using alcohol in large quantities is not favorable [13].…”
