“…where ν is the kinematic viscosity of the mixture in mm 2 /s; φ is the volume fraction; ξ , , and, ω are adjustable temperature parameters; and T is the temperature in K. The parameters a, b, c, d, e, and f are found from the experimental data given in the article of Cano-Gomez and Iglesias-Silva (2019). Oxidation stability of biodiesel/diesel blends with pentanol addition (10 and 15%) was investigated by Peer et al (2017). They concluded that pentanol addition of only up to 10% volume to Calophyllum inophyllum biodiesel/diesel blends increased the oxidation stability, but above which it decreased the storage stability.…”

Of several higher alcohols such as pentanol, hexanol, octanol, decanol, dodecanol, phytol, and fusel oil, pentanol isomers have recently received remarkable attention as alternative fuels for diesel engines because they emit less greenhouse gases and harmful pollutants. Because of great potential as a blending component and physicochemical properties of pentanol, binary blends such as diesel/pentanol and biodiesel/pentanol and ternary blends such as diesel/biodiesel/pentanol were mainly studied in the conventional diesel engine. Quaternary blends of diesel, biodiesel, straight vegetable oil, and pentanol were also investigated. Very few information related to the application of pentanol to advanced compression ignition (CI) engine is available in the literature. The diesel/pentanol blends coupled with exhaust gas recirculation (EGR) technology could simultaneously reduce NOx and soot emissions from CI engine. Further, diesel/pentanol blends generally produced higher CO and hydrocarbon (HC) emissions than did diesel fuel. However, CO and HC emissions were significantly reduced by mixing the cetane improver with the blends. Up to 45-50% n-pentanol/diesel blends can be safely used in diesel engines without any engine modification or any additive. However, in terms of kinematic viscosity, lubricity, and oxidation stability of diesel/pentanol blends, the use of pentanol should be limited to concentrations below 10%. Generally, in the studies of biodiesel/pentanol blends in CI engines, the reduction of CO, HC, NOx, and smoke emissions was observed compared to neat biodiesel. For ternary blends, diesel/biodiesel/pentanol blends were mainly investigated by the researchers. The emission characteristics in terms of CO, HC, NOx, and smoke opacity showed the different trends according to the pentanol proportion in the ternary blends, particularly <10% or more than 10%. To increase the biofuels in the CI engine, more studies for the quaternary blends of pentanol are required.

“…While no specific research addresses the quality of diesel fuel found in the 11 Latin America countries targeted in this research, several peer‐reviewed papers describe the characteristics of fuel blending, an important factor when dealing with diesel fuel quality. For instance, while evaluating the use of alcohol‐blends with biodiesel, Peer et al . determined that mixing alcohol, biodiesel, and fossil diesel fuels is common in developing Latin American countries to deal with diesel fuel shortages.…”

Between 2010 and 2015, engines in 20-ton excavators in Latin American countries failed with low hours of usage. System maintenance data such as engine oil samples are critical to address engine durability issues seen in equipment operating in the Latin America region. Risk analysis addressing premature engine wear in the Latin America region has not been described in peer-reviewed literature. Thus, the primary objective of this paper is to apply a system engineering standard risk model evaluation to identify, quantify, and prioritize cost risks associated with diesel engine durability in Latin America. This research is based on several data sources, including a database of 7561 engine oil analysis results for the period of 2010 through 2015. These results were obtained from oil analysis laboratories located in the following Latin American countries: Bolivia, Colombia, Costa Rica, Dominican Republic, Ecuador, Guatemala, Honduras, Mexico, Paraguay, Peru, and Uruguay. This research applied the standard risk model and cataloged the root-causes of risks under two groups: fuel and environment. The paper identified a cause and effect correlation between risk drivers and abnormal oil sample analysis results. After calculating, prioritizing, and mapping each risk, the research concludes that diesel sulfur content and diesel quality are the primary risks that should be addressed in machinery operating in Latin America. Risk and cost threshold formulas are presented in this research and support the conclusions.
