“…Kumar et al [9] investigated an engine fuelled with vegetable oil and discovered that NO x emission decreased with DEE addition. Iranmanesh et al [10] improved the combustion and emission of a diesel engine that was fuelled with biodiesel by using DEE as a cetane number improver. A combination of the premixed DEE and diesel injection on exhaust emissions was studied by Cinar et al [11], and they reported that the introduction of premixed DEE could decrease NO x emissions as compared with diesel combustion.…”

The combustion and emission characteristics of a turbo-charged, common rail diesel engine fuelled with diesel-biodiesel-DEE blends were investigated. The study reports that the brake-specific fuel consumption of dieselbiodiesel-DEE blends increases with increase of oxygenated fuel fractions in the blends. Brake thermal efficiency shows little variation when operating on different dieselbiodiesel-DEE blends. At a low load, the NO x emission of the diesel-biodiesel-DEE blends exhibits little variation in comparison with the biodiesel fraction. The NO x emission slightly increases with increase in the biodiesel fraction in diesel-biodiesel-DEE blends at medium load. However, the NO x emission increases remarkably with increase of the biodiesel fraction at high load. Particle mass concentration decreases significantly with increase of the oxygenated-fuels fraction at all engine speeds and loads; particle number concentration decreases remarkably with increase of the oxygenated-fuels fraction. HC and CO emissions decrease with increasing oxygenated-fuels fraction in these blends.

“…percentage of DEE reduced the in-cylinder pressure due to the increased was higher than diesel fuel, due to its lower bulk modulus of elasticity and higher latent compared to diesel fuel [11]. Lower bulk modulus increases the time required for the fuel to reach the desired delivery pressure inside the fuel pump and hence decreases the dynamic injection timing.…”

“…In spite of higher cetane number of DEE over neat diesel, the studies conducted by Rakopoulus et al [11,12]indicated that, the ignition delay period was getting increased when DEE was blended with diesel fuel. Moreover, lower in-cylinder pressure and temperature were reported or DEE blends than neat diesel.…”

In this research work, an experimental investigation was carried out to study the combustion, performance and emission characteristics of a single cylinder water cooled diesel engine, when fueled with blends of diethyl ether and diesel. Three different blends with 5%, 10% and 15% of diethyl ether were tested and compared with neat diesel fuel at different load conditions. Fuel consumption, in-cylinder pressure and exhaust emissions were measured at all load conditions. When compared to neat diesel fuel, the blends of diethyl ether exhibited reduced carbon monoxide, nitrogen oxide and smoke emissions with increased hydrocarbon emissions. Lower brake specific energy consumption and increased brake thermal efficiency were observed for the blended fuels. The in-cylinder peak pressure and the heat release rate for blended fuels were lower compared to the diesel fuel. It was evident from the experimental results that 15% of diethyl ether blend has the potential of overcoming the existing NO x -smoke trade-off in diesel engines.

“…Experiments conducted by Iranmanesh for DDE additive amounting up to 10 % [14] and up to 20 % [15] have shown a significant decrease in NO x emission (up to 51 %) for higher DDE rates. The smaller fuel viscosity achieved in this way leads to the improvement of fuel atomization and combustion process; however, it does not improve the PM emission, and there has been recorded even higher CO emission.…”

The paper discusses the issues of the influence of the fuel spray formation on the generation of self-ignition spots and the development of pre-flame processes in the cylinder of a model diesel engine. The investigations were carried out for a standard diesel fuel and two other types of fuel that were mixtures of ethanol, butanol, and diethylether in a variety of proportions. By applying optical methods of analysis, the authors determined the geometrical indexes of the injected fuel spray as well as fuel mass distribution in the longitudinal and transverse cross section of the fuel spray during the injection process. The location and number of the self-ignition spots in the combustion chamber were evaluated on the basis of a comparison under various conditions: in presence of the charge swirl and at the lack of it. Research conducted for the single-cylinder engine confirmed the possibility of the use of diesel-like fuels for compression ignition engines.
