“…Authors [27] pointed to a need of the injection strategy optimization to reduce HC and CO emissions. Similar to authors [27], numerous studies [5,10,13,23,24] shows that NO x , PM and smoke emissions are slightly lower than those of the diesel fuel operation, however, HC and CO emissions rise. According to the author's [10,23], the HC and CO emissions could be reduced with an earlier injection period, which would promote the oxidation reaction of the HC and CO emissions.…”

The ecological issues and the depletion of crude oil, has led the researchers to seeking for non-petroleum based alternative fuels, along with more advanced combustion technologies, and after-treatment systems. The use of clean alternative fuels is the one of the most perspective method that aiming at resolving of the said issues. One of the promising alternative fuels that can be used as a clean high efficiency compression ignition fuel with reduced of toxic emissions is dimethyl ether (DME). Moreover, it can be produced from various feedstocks such as natural gas, coal, biomass and others. This article describes the properties and the potential of DME application on the combustion and emission reduction characteristics of the compression ignition engines.

“…El biodiésel, el etanol, el metanol son los principales combustibles alternativos prospectivos que pueden reducir el calentamiento global, el consumo de combustibles fósiles y las emisiones de escape. Actualmente, se genera una masiva búsqueda del uso de aceite vegetal en los motores diésel seguido de la utilización del biodiésel con características técnicamente mejoradas en comparación con los aceites vegetales (Chen et al, 2018). Generalmente, la producción de biodiésel a través de la transesterificación de aceites vegetales es el método más reconocido y aceptado en todo el mundo (Mumtaz et al, 2012).…”

Autor a quien debe ser dirigida la correspondenciaResumen El objetivo principal de este trabajo es evaluar las prestaciones mecánicas y de opacidad de los combustibles diésel y mezclas de diésel/biodiésel en vehículos tipo camioneta a 2810 msnm, mediante pruebas dinamométricas. Para el estudio, se seleccionaron dos camionetas en las que se experimentaron cuatro mezclas: B10 (10% biodiésel), B20 (20% biodiésel), B10A (10% biodiésel con aditivos), y B20A (20% biodiésel con aditivos). Se determina la incidencia en el rendimiento mecánico del vehículo a partir de la realización de pruebas de potencia, par motor y opacidad. Se obtiene que la mezcla B10A es la más óptima para reemplazar al diésel puro, logrando mantener el par motor y la potencia sin variaciones significativas con relación al diésel para un nivel del 95.0 % de confianza. Se concluye que a medida que aumenta el porcentaje de biodiésel se disminuye en 2.37 % el par motor y en 1.37 % la potencia con relación al diésel. Además, los combustibles con mezclas de biodiésel y con la adicción de aditivo reducen la emanación de hollín bajo el criterio de opacidad hasta aproximadamente un 37%. AbstractThe main objective of this work is to evaluate the mechanical and opacity performance of diesel fuels and diesel/biodiesel mixtures in van vehicles at 2810 meters above sea level, by means of dynamometric tests. For the study, two van in which four mixtures were evaluated: B10 (10% biodiesel), B20 (20% biodiesel), B10A (10% biodiesel with additives), and B20A (20% biodiesel with additives). The impact on the mechanical performance of the vehicle from testing of power, torque and opacity were determined. It is obtained that the B10A mixture is the optimum one to replace the pure diesel, managing to maintain the torque and power without significant variations in relation to the pure diesel for a level of 95.0% confidence. It was concluded that as the percentage of biodiesel increases, engine torque decreases by 2.37% and the power by 1.37% in relation to pure diesel. In addition, fuels with biodiesel mixtures and with additives reduce soot emission under the opacity criterion up to approximately 37%.

“…As can be seen from Figure 8, Figure 9, and Figure 10, the NO x formation is depends on combustion duration. Any small changes in combustion duration resulted in a change in NO x emissions [15]. Therefore, from the results, it is analyzed that the retarding combustion duration is preferred for NO x emission.…”

The research presented in this article expresses experimental results on combustion duration effect on the dual fueled engine. In particular, the research was focused on the emissions occurred specifically from a hydrogen-ethanol dual fueled engine. This study was performed on a compression ignition engine that was converted to run and act as a spark ignition engine. This modified engine was fueled by hydrogen–ethanol with various percentage substitutions of hydrogen. The substitution was altered from 20 to 80% at a constant speed of 1500 rpm. The various engine emission characteristics such as CO, Hydrocarbon, and NOx were experimentally determined. This study resulted that at a compression ratio of 11:1 and combustion duration of 25°CA, the best operating conditions of the engine were shown. Moreover, the optimum fuel combination was established at 60 to 80% of hydrogen substitution to ethanol. The experimental results also revealed that at 100% load and at compression ratios 7, 9, and 11; the CO and HC emissions have decreased while NOx increased and followed with the increase in the percentage of hydrogen addition and combustion duration. It was concluded that the retarding combustion duration was preferred for NOx emission control in the engine.
