“…In terms of emission reduction, the oxygen content of the fuel has been reported to be a major factor compared to the other properties [7][8][9]. In this regard, a low volume of fuel additives with high oxygen content could play an import role boosting the emission reduction.…”

h i g h l i g h t sOxygen ratio was used instead of the equivalence ratio. Oxygen ratio decreases with engine load, but increases with engine speed. IMEP, BMEP, friction power, CO 2 , HC, PM and PN decreased with oxygenated fuels. BSFC, BTE and NOx increased with oxygenated fuels. Accumulation mode count median diameter decreased with oxygenated fuels. a b s t r a c tThis study investigates the effect of oxygenated fuels on engine performance and exhaust emission under a custom cycle using a fully instrumented 6-cylinder turbocharged diesel engine with a common rail injection system. A range of oxygenated fuels based on waste cooking biodiesel with triacetin as an oxygenated additive were studied. The oxygen ratio was used instead of the equivalence ratio, or air to fuel ratio, to better explain the phenomena observed during combustion. It was found that the increased oxygen ratio was associated with an increase in the friction mean effective pressure, brake specific fuel consumption, CO, HC and PN. On the other hand, mechanical efficiency, brake thermal efficiency, CO 2 , NOx and PM decreased with oxygen ratio. Increasing the oxygen content of the fuel was associated with a decrease in indicated power, brake power, indicated mean effective pressure, brake mean effective pressure, friction power, blow-by, CO 2 , CO (at higher loads), HC, PM and PN. On the other hand, the brake specific fuel consumption, brake thermal efficiency and NOx increased by using the oxygenated fuels. Also, by increasing the oxygen content, the accumulation mode count median diameter moved toward the smaller particle sizes. In addition to the oxygen content of fuel, the other physical and chemical properties of the fuels were used to interpret the behavior of the engine.

“…Gómez et al (2016) [10] showed that the negative effect of ethanol on NO x emissions and the positive effect on PM are both attenuated by the altitude. Other authors also came to the same conclusion under steady state engine tests [11]. However, none references can be found focused on the study of the combined effect of altitude under transient sequences when ED fuel blend is used.…”

“…Research conducted by He et al (2011) suggests that engine smoke increased by rates of 30% to 34% when operating diesel engines above 1,000 meters. Liu, Shen, Bi, and Lei (2014) reported a direct correlation between atmospheric pressure and the level of soot generated in diesel engines.…”

The Latin American region has many important ongoing infrastructure projects. It is a global source of mining materials such as copper and iron. Thus, the region is an important market for construction equipment manufacturers such as Caterpillar, John Deere, Komatsu, Volvo, and CNH. However, it is not financially feasible for these manufactures to test construction machines in all 33 countries. Consequently, there is a significant lack of engine system understanding in this region due to its diverse operating conditions. This research provides a system engineering analysis of how diesel engine durability is affected by the environmental factors such as altitude and fuel quality in Latin America. Examination of engine oil analyses shows that oil condition provides a leading indicator of premature internal engine wear in Latin America. The study further relates environment factors in Latin America such as altitude to machine diagnostic trouble codes.
