“…The use of biodiesel and ethanol as surrogate to diesel fuel can help to decrease the overall concentrations of monoaromatic hydrocarbons in the exhaust gas of combustion engines, as shown by Di et al . [5] , but the concentration of oxygenates is increased. Because xylenes are present in gasoline several investigations of their combustion and oxidation behavior under different conditions have been performed, previously.…”

A fuel-rich ( = 1.79) m -xylene flame (7.3% m -C 8 H 10 , 42.7% O 2 , 50.0% Ar) at low-pressure (40 mbar) was investigated with focus on the reactive fuel radicals (C 8 H 9 ) and the first decomposition steps leading to C 8 H 8 isomers. The results show that an isomerization of the m -xylyl radical to o -and p -xylyl must take place to explain the observed intermediates in agreement with pyrolysis experiments. Important higher polycyclic aromatic hydrocarbons (PAHs) relevant to soot formation were also identified. All Measurements were performed with a molecular-beam mass spectrometry (MBMS) setup at the Swiss Light Source (SLS), where single-photon ionization with VUV radiation offers soft ionization of the sampled species. Isomer-selective detection with unprecedented resolution is achieved by a combination of time-of-flight mass spectrometry and imaging photoelectron photoion coincidence (iPEPICO) spectroscopy. In principle, species can be identified by comparison of measured ionization efficiency (PIE) curves with known or calculated ionization energies of expected species. For convoluted signals of several species, this procedure works well for the isomer with the lowest ionization energy. Changes in the slopes of the ionization efficiency curve do not necessarily correlate with ionization thresholds of other isomers and the assignment of higher thresholds can become difficult. PEPICO spectrometry, which detects the electrons that are produced in the ionization process in coincidence with the ions, enables the measurement of mass-selected threshold photoelectron spectra (ms-TPES). These spectra improve the detection capability of isomers because vibrational transitions from the neutral into ionic states can be observed and used as a fingerprint of a specific molecule. The JID: PROCI [m; June 30, 2016;16:41 ] ms-TPES are compared with reference spectra from the literature or Franck-Condon simulations. Quantification of the major species as well as several intermediate species for this fuel-rich m -xylene flame yields a data set for model validation and experimental results are compared with five kinetic reaction models from the literature.

“…Ethanol has a lower calorific value and Cetane number in comparison with diesel fuel. Low calorific value of ethanol leads to an increase in specific fuel consumption and low Cetane number reduces the Cetane level of the diesel and ethanol blend (Qi et al, 2010;Di et al, 2009). Another alternative bio-fuel for diesel engines is butanol.…”

In this study, performance and exhaust emissions of a diesel engine fueled with Fuel A (60% diesel-30% biodiesel-5% ethanol-5% butanol) and Fuel B (40% diesel-50% biodiesel-5% ethanol-5% butanol) were investigated. The biodiesel produced from trap grease was obtained with an oil separator. Fuel A and Fuel B were tested in a single cylinder, four-stroke diesel engine at full load conditions. Compared with diesel fuel, the performance characteristics of blend fuels slightly deteriorated while the emission characteristics improved significantly. CO and HC emissions decreased by 87.01 and 87.50%, respectively.
