“…PEG is also known as polyethylene oxide (PEO) when its molecular weight is higher than 20,000 g/mol. This alcohol was used as ignition improver to produce the ED95 (ethanol and BERAID 3525/3555) [17,18,33,[48][49][50]. The PEG is soluble in water, methanol, ethanol, benzene and dichloromethane, but insoluble in ether ethylic and hexane.…”

“…The PEG is soluble in water, methanol, ethanol, benzene and dichloromethane, but insoluble in ether ethylic and hexane. In the compression ignition process, the following can be observed: the higher the molecular weight of PEG, the lower the amount of PEG in the blend with ethanol in order to increase the cetane number; and the higher the amount of PEG in the blend with ethanol, the higher the cetane number (the lower the ignition delay) [17,49]. Previous tests, made in a rapid compression machine, with mixtures of ethanol and PEG 400 and 600, showed a minor amount of additive necessary, when used the additive with major molecular weight in order to burn the ethanol under compression ignition conditions and similar compression ratios [51].…”

The world recognizes that the main source of energy used in transportation is diesel fuel because it is more economical and is also more efficient. For this reason, various sectors of transport and fuel production are developing new technologies aiming at the replacement of traditional fossil fuels by other renewable sources. In the current market, it is possible to find systems that run on blends of diesel and other renewable fuels and test systems that run on mixtures of ethanol and some other substance to reduce auto-ignition. To be able to use ethanol in compression ignition (CI) engines where diesel fuel is typically used, the poor flammability of ethanol under compression ignition conditions is the major problem to be overcome. The techniques used in trials with CI engines to correct this problem are preheating the air in the intake manifold, increasing the compression ratio or the addition of an ignition improver for ethanol. In this study, different tests were carried out in a rapid compression machine using ignition improvers derived from polyethylene glycol. Tests were conducted for different instants for the start of injection of the mixtures and different compression ratios.

<div class="section abstract"><div class="htmlview paragraph">Currently, several studies are being carried out to replace diesel oil with alternative fuels in compression ignition engines. Ethanol is a strong candidate, thanks to its extensive feedstock, low emissions and low cost. Although it also has easy adaptability to engine technologies, there are some difficulties that need to be eliminated regarding its direct use in compression ignition engines (diesel cycle). The present work aims to evaluate the ignition delay of ethanol/peg 600 blends in a four-stroke compression-ignition engine, in relation to maximum pressure and maximum rate of pressure rise under different experimental conditions. Parameters such as engine speed, load and compression ratio, in addition to fuel injection advance and percentage of additive were analyzed. For this study, a code was developed in Matlab computer software capable of analyze data collected through Indicon-AVL, to tests carried out at the Institute of Mobility and Sustainable Energy (IMES - PUC-Rio). From the data generated, it was possible to prove that the use of ethanol additive can be carried out with some modifications in the diesel engine, but adjusting the parameters mentioned above is essential to optimize the combustion process.</div></div>
