“…The biomass feedstock consists of cellulose, hemicellulose, and lignin, which makes new production pathways possible. As the fuels help to establish highly efficient and "clean" combustion, it is expected that the new fuels will differ from today's ones as shown by Leitner et al 1 For instance, the currently investigated renewable fuels contain oxygen atoms because they are made from biomass which was shown by Hoppe et al 2 To find suitable fuel molecules, a tool based on quantitative structure−property relationships was developed by Hechinger et al, 3 which initially generates all possible molecular structures according to valence rules and given restrictions (e.g., number of carbon atoms) developed by Dahmen et al 4 For gasoline-like fuels, the restrictions are as follows. A derived cetane number below 9, a heating value of >30 MJ/kg, a boiling point between 50 and 100 °C, and an enthalpy of vaporization of <60 kJ/kg air,λ=1 were selected by Hoppe et al 5 These parameters are discussed in more detail in the study by Hoppe et al 2 In that prior work, the selection of fuels is also more thoroughly explained.…”

Experimental and Numerical Study of Abnormal Combustion in Direct Injection Spark Ignition Engines Using Conventional and Alternative Fuels

In this paper, the potential of alternative fuels to reduce preignition in engines is primarily investigated. Two ketones (2-butanone and 3-methylbutanone), a furan (2-methylfuran), and five alcohols (ethanol, iso-propanol, 2-butanol, iso-butanol, and 1-propanol) are compared to three conventional fuels (RON95E0, RON95E10, and iso-octane). If the alternative fuels can reduce preignition significantly, the efficiency of spark-ignition engines can be potentially increased. One major aim is to categorize the fuels in terms of preignition resistance. Additionally, the distributions of the initial preignition kernels are measured by high-speed luminescence imaging to analyze the reason for preignition. Furthermore, the occurrence of measured preignition is compared with computed ignition delay times at the pressures and temperatures of the engine load points used to find out whether the mixture is prone to autoignition in the bulk gas phase. This is most likely the case for the three conventional fuels because of thermodynamically critical gas-phase conditions. Seemingly, preignition is not induced by droplets, presumably because of an improved injector targeting. Moreover, the preignition resistance of the alternative fuels is significantly higher (critical intake pressure difference: ∼2 bar) compared to that of the three conventional fuels. It can also be concluded that 2-butanone is most resistant against preignition. Similarly, alcohols and 3-methylbutanone are highly beneficial compared to conventional fuels. Overall, the most important fuel properties for preignition appear to be research octane number and enthalpy of vaporization. Apparently, ignition is caused by glow ignition at a hot surface (spark plug) only for 2-methylfuran, iso-butanol, and 1-propanol.

“…Design methodologies can avoid expensive and time-consuming trial-and-error experimental campaigns. Similar approaches have been successfully used in several fuel development projects [4,[53][54][55][56][57][58][59][60], typically to design tailor-made molecules for fuel application. That is, molecular building blocks were computationally joined and reassembled to generate new molecules with good fuel blendstock potential.…”

Identification of Promising Alternative Mono-Alcohol Fuel Blend Components for Spark Ignition Engines

2020

Alcohols are attractive fuel blendstocks for spark ignition engines due to their high octane values and potentially positive influence on performance and emission. Although methanol, ethanol, and butanol have been widely studied, other biomass-derived alcohols may have similar or better properties. However, it is not feasible to experimentally investigate the fuel potential of every molecule. The goals of this study were to develop a methodology for rapid screening of a fuel property database for mono-alcohols and to identify alcohols with the potential of blending to produce advantaged motor gasolines. A database was developed with 13 fuel properties of all saturated C1-C10 mono-alcohols. A decision framework was used to evaluate alcohols suitable for blending in gasoline for spark ignition engines in two scenarios: low-range (up to 15 vol%) blends and high-range (greater than 40 vol%) blends. The low-range blend cases resulted in the identification of 48 alcohols. In the case of high-range blending, only six alcohols were found to be suitable. This is the first study to systematically evaluate all C1-C10 saturated alcohols for blending with gasoline using relevant fuel properties. A novel aspect of this study is the evaluation of the influence of errors in predicted property values. These scenario screenings focus attention on a smaller number of promising candidate molecules, and the approach could be modified for other classes of fuel molecules, engine types, and fuel blending goals.

“…The authors reported that Malaysia currently implemented biofuel through B5 diesel with 5 % blend of fatty acid methyl ester obtained from the palm biomass, there are no specific standards to compare the B5 biofuel with the conventional diesel. Most of the current studies on fuel blend design employ a forward approach relying on property prediction (Hechinger et al, 2012) from a set of fuel blend compositions (Manuel and Wolfgang, 2016).…”

Climate change is global issues with significant economic, social and environmental implications. Climate change mitigation in Asia has large impacts on global CO 2 emission reduction. CO 2 emission is the largest source of greenhouse gas emission constitutes about 65 % of the total emission. Low-carbon Society initiative is one of the various mechanisms that have been deployed to achieve green economic growth, societal well-being and development, environmental preservation and management in a holistic manner. Energy efficiency improvement in Asia will be a key factor to tackle the climate change issues. Water and energy conservation, green transportation and low emission technology are the key aspects to catalyse the shift towards climate-resilient economic growth. The latest developments in these aspects are reviewed in this special volume to sustain the development of low-carbon emission in Asian countries. The use of holistic management system to integrate these key areas for long-term sustainability goal is also highlighted.
