“…DEE is also blended with diesel to increase the brake thermal efficiency and reduce emissions in compressioneignition engines (Iranmanesh et al, 2008;Sudheesh and Mallikarjuna, 2010;Michie et al, 2005). DEE has a high cetane number and is used as a starting fluid in combination with petroleum distillates for gasoline and diesel engines because of its high volatility and low flash point.…”

“…Generally, DEE is used as a cold starting aid in IC engines. The DEE is also blended with diesel for improving BTE and reducing the emissions in CI engines (Iranmanesh, Subrahmanyam, and Babu 2008). Onishi et al were the first to introduce controlled autoignition in a two-stroke engine in order to reduce combustion instability at part-load operations.…”

In this study, a single-cylinder, water-cooled, direct-injection, compression ignition (CI) engine is operated on the homogeneous charge CI (HCCI) mode using acetylene and diethyl ether (DEE) as fuels. Acetylene is inducted as a main fuel and a small quantity of DEE is injected into the intake manifold for controlling combustion phasing. The engine performance and exhaust emission characteristics are investigated experimentally under various operating conditions. From the results, it is found that brake thermal efficiency of the acetylene-DEE HCCI mode is comparable with that of the conventional CI mode. It has a wide operating range of 0-4.2 bar brake mean effective pressure without exhaust gas recirculation compared with the liquid fuels-HCCI mode. The engine could easily start in the HCCI mode using DEE alone. Nitric oxide and smoke emissions are at ultra-low level. Hydrocarbon emissions are comparatively lower at lower loads and higher at higher load conditions. Carbon monoxide emissions are comparable with that of the conventional CI mode.

“…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.
