Abstract
To produce biodiesel from waste oil and use it as an alternative fuel in compression ignition (CI) engines is an efficient way to eliminate this harmful compound. In this experimental study, the effects of biodiesel derived from waste oil on emission and performance characteristics of CI engine were investigated. The production of biodiesel was realized at the condition: 9wt% acid catalyst amount, 9:1 molar ratio, 60oC reaction temperature and 120min reaction time. Biodiesel and diesel were mixed with different volumetric ratios and the properties of each blend were analyzed. Each blend was tested with a direct injection CI engine to see the effect of biodiesel on performance and emission characteristics. In conclusion, blends showed similar results in terms of performance comparing to diesel. The use of biodiesel derived from waste oil led to decrease in hydrocarbon (HC), carbon monoxide (CO) emissions and smoke opacity up to 81.25%, 55.02% and 40.48% respectively while led to slight increase in nitrogen oxides (NOx) emissions in general.
Highlights
Fossil-based fuels used in the production of energy release a large share of pollutant emissions into the environment
Higher density and viscosity of biodiesel may cause flow problems that lead to lower combustion and thermal efficiency which decrease performance characteristics of diesel engine
This paper focused on production biodiesel from waste oil and use as an alternative fuel in compression ignition (CI) engines
Summary
Fossil-based fuels used in the production of energy release a large share of pollutant emissions into the environment. The pollutant emissions, especially CO, HC, NOx and PM, cause regional air pollution that threaten people health and environment worldwide (Sanjid et al, 2014). They have contributed to the enhancement of the natural greenhouse effect led to climate change. Because of their high proportion in releasing pollutant emissions, fossil-based fuels are considered as the main reason of global climate change (Resitoglu et al, 2015). The alternative sources met these factors may be listed as solar, wind, hydro, nuclear and biomass energy. Biodiesel as one of the biomass-based fuels is an alternative and renewable source for fossil-based diesel (Qi et al, 2016; Ahmed et al, 2014)
