“…Unfortunately, the lower combustion temperature also leads to the higher HC and CO emissions [20]. Qi et al [21] investigated the performance, emission and combustion characteristics of a common rail direct injection compression ignition (CI) engine fueled with diesel tung oil-ethanol blended fuels with different ratio of volume fraction. The experimental results indicated that, compared with diesel fuel, the ignition delay showed a little longer, the peak in-cylinder pressure and HRR were higher, while the combustion duration was slightly shortened for the blended fuels.…”

“…The NO x emissions of the blended fuel were lower at low engine loads and slightly higher at high engine loads. Smoke emissions were drastically reduced at high engine loads [21]. This paper presents the results of experimental researches of co-combustion of diesel-biodiesel-ethanol fuel in direct injection Diesel engine.…”

The paper presents results of co-combustion of diesel-biodiesel-ethanol fuel blend in direct injection Diesel engine. Test was performed at constant rotational speed at three commonly used loads of this engine: 100%, 85%, and 70% of load. During the test hydrated ethanol was used at a concentration of 89% of alcohol. In this study, the ethanol fuel was added to diesel-biodiesel fuel blend with concentrations up to 50% with the increment of 5%. The biodiesel was used as an additive to prevent the stratification of ethanol and diesel blends. Thermodynamic parameters of engine were analyzed, and combustion process and exhaust emission were characterized. It turned out that with the increase in engine load is possible to utilize larger ethanol fraction in blend. With the increase of ethanol fuel in blend the increase in ignition delay (38.5% for full load) was observed, but burning duration decreased (49% for full load). The ethanol fuel share in blend generally causes the increase in NO x emission (42% for full load) due to higher oxygen content and higher in-cylinder temperatures. It turned out that, at full load the unrepeatability of indicated mean effective pressure was near the same up to 50% of ethanol fuel in blend (about 2%). In case of partial load at higher ethanol fuel fraction the increase in indicated mean effective pressure un-repeatability was observed.

“…The experimental studies revealed that vegetable oils reduce HC, CO and CO2 emission due to fuel-borne oxygen in their structure. However, the primary drawback of vegetable oil is its high viscosity and poor volatility which affects fuel atomisation, evaporation and air-fuel mixing [8]. Therefore, use of vegetable oil in CI engines can lead to poor engine performance, piston ring sticking and injector clogging [9].…”

“…Estos últimos poseen bajos contenidos de azufre y compuestos aromáticos, altos puntos de inflamación y poder lubricante; sin embargo, su viscosidad elevada ha limitado su uso como combustible. Emplear aceite vegetal, aunque puede constituir una opción ambientalmente amigable para su uso en aplicaciones automotrices, no ha tenido gran acogida debido a los problemas derivados de su uso, tales como taponamiento de filtros e inyectores, combustión incompleta y depósitos de carbón en la cámara de combustión, entre otros (Qi et al, 2017;Suh and Lee, 2016;Corsini et al, 2015). Procesos como la transesterificación, pirolisis, micro-emulsión y mezclas con combustible diésel, son algunas técnicas empleadas para reducir la viscosidad de los aceites vegetales (Atmanli et al, 2015;Rakopoulos et al, 2014).…”

Se analiza el desempeño de mezclas de petrodiésel, biodiésel de palma y oleorresina de copaiba refinada, como combustible en un generador eléctrico. Los ensayos fueron realizados en una planta eléctrica provista con un sistema de alimentación secundario para monitorear el desempeño de las mezclas y el combustible de referencia en condiciones de carga plena. Se estudió la influencia del porcentaje de oleorresina en las mezclas sobre el consumo de combustible, la potencia entregada y la emisión de gases de escape. Se estableció una disminución de hasta el 19% en la potencia generada por la planta respecto a la energía suministrada por el motor operado con diésel. En relación a la emisión de gases, la adición de oleorresina de copaiba refinada al combustible, redujo la concentración de CO y SO2 en los gases de escape. De acuerdo a los resultados, la incorporación de oleorresina de copaiba al diésel comercial, podría constituir una opción ambientalmente amigable. Sin embargo, el aumento en la viscosidad del combustible limitaría su uso en aplicaciones automotrices.
