“…Meanwhile ethylene glycol ethyl ether and propyl ether types biodiesels and diethylene glycol and triethylene glycol monomethyl ether types of biodiesels were developed to understand their effects. Table 1 lists some of new types of biodiesels and their fuel properties our group developed in recent years [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50]. The new types of biodiesels have a CN around 70, oxygen content about 17%, which are higher than FAME.…”

Biodiesel is regarded to be a renewable, CO2 neutral and thus sustainable biological alternative diesel fuel. With attention to the reduction of petroleum import, PM 2.5 aerosol particles and the greenhouse effect gas CO2, biodiesel has drawn great research interests and efforts in the past decade in China. Generally, biodiesel refers to fatty acid methyl ether (FAME) which has a proved effect in reducing diesel emission, particularly PM. However, FAME has a limited cetane number and oxygen content, to study the effects of elevated cetane number and oxygen content on fuel properties, engine combustion and emissions, ethylene glycol monomethyl ether is used to produce a series of new models of biodiesels by transesterification method. The feedstocks are rapeseed oil, soybean oil, peanut oil, palm oil and cottonseed oil. Ether group alcohols used in this study include ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, propylene glycol monomethyl ether, diethylene glycol monomethyl ether, triethylene glycol monomethyl ether. The molecular structure was proved by FT-IR and NMR analyses. Fuel properties were measured based on the corresponding standards. The developed new model biodiesels have cetane number (CN) over 70 and oxygen content over 17% by mass, which are higher than FAME (50 CN and 11% oxygen). They have the same level of lower heating value as FAME, but have a higher density, which helps to compensate the decrease of engine power. Meanwhile, the engine tests were carried out to investigate the effects of ether ester group on engine combustion and emissions. The test results show that FAME reduced smoke 30% to 50%, while the new model biodiesel fuels reduced engine smoke as high as 80% and have the potential to decrease engine HC, CO and NOx emissions 50% or more.

“…6 Recently, a kind of novel biodiesel was synthesized by the transesterication reaction of FAMEs with short chain glycol ethers. 7,8 Compared with the conventional biodiesel, novel biodiesel not only has the advantages of traditional biodiesel, but also attempts the introduction of ether groups into the molecules, and the amount of oxygen contained can be largely improved. So, engine-out exhaust emissions and combustion are effectively reduced.…”

“…In the study, calcined sodium silicate was used as a solid basic catalyst, and such parameters as the calcination temperature, amount of catalyst, molar ratio of FAME to EGMME, reaction temperature, and reaction time were optimized. As early as 2006, the authors had developed ethylene glycol monomethyl ether soyate as a novel biodiesel for the first time . The investigation manifested that when a single cylinder diesel engine was fueled with the biofuel under partial loads substituting for diesel fuel, carbon monoxide (CO) emissions were reduced by up to 79.1%, unburned hydrocarbon compounds (HC) emissions were decreased by up to 61.6%, and smoke opacity was lessened by 54.7% to 85.7%.…”

In the article, a new biofuel named ethylene glycol monomethyl ether palm oil monoester (EGMMEPOM) is developed as a clean alternative fuel for diesel engine. It was synthesized through transesterification reaction with a refined palm oil and ethylene glycol monomethyl ether (EGMME) as reactants and potassium hydroxide (KOH) as catalyst under certain conditions. Its chemical structure was identified through Fourier transform‐infrared (FT‐IR) spectrum, 1H nuclear magnetic resonance (1H NMR) spectroscopy, and gel permeation chromatography (GPC) analyses, and its main fuel properties were measured precisely. A two‐cylinder diesel engine was utilized to investigate its combustion performances, fuel economy and emissions characteristics. When the engine was operated with the new biofuel at a high speed of 2000 r/min instead of diesel fuel, smoke emissions were decreased by 26.3% to 70.0% with carbon monoxide (CO) and hydrocarbon compounds (HC) emissions significantly reduced. Nitrogen oxides (NOx) emissions were decreased by 14.0% to 23.5%. The new palm oil monoester has a cetane number as high as 77.0 which leads to a shorter autoignition delay duration than diesel fuel and makes the curves of in‐cylinder pressure increasing rate and heat release rate shift forward 2 to 3 degrees crank angle (°CA). Owing to more amount of oxygen existing in the new biofuel, both peak in‐cylinder pressure increasing rate and peak heat releasing rate decreased. © 2015 American Institute of Chemical Engineers Environ Prog, 35: 241–249, 2016
