“…Gumus [10] also reported that the start of ignition for biodiesel was advanced by up to 1.65deg. The advanced start of ignition is occurred due to the physical properties of the biodiesel such as higher bulk modulus [14], [46] higher viscosity [41], [45] and higher cetane number [47], [16].…”

“…The main findings from the literature reviewed indicate that biodiesels, when used in engines, have comparable power, BSFC and brake thermal efficiency, as compared to engines running with diesel. Biodiesel also offers significant advantages of significant portability and although there is not at overwhelming agreement many studies have reported higher combustion efficiency with the Biodiesel use [8], [9], [10]. Furthermore bio-diesel offers lower sulphur and aromatic content, a higher cetane number and higher lubrication effects [11].…”

Biodiesel is one of the alternative fuels which is renewable and environmentally friendly and can be used in diesel engines with little or no modifications. In the present study, experimental investigations were carried out on the effects of biodiesel types, biodiesel fraction and physical properties on the combustion and performance characteristics of a compression ignition (CI) engine. The experimental work was conducted on a four-cylinder, four -stroke, direct injection (DI) and turbocharged diesel engine by using biodiesel of waste oil, rapeseed oil and corn oil and normal diesel. Based on the measured parameters, detailed analyses were carried out on cylinder pressure, heat release rate and brake specific fuel consumption (BSFC). It has been seen that the biodiesel types do not result in any significant differences in peak cylinder pressure and BSFC. The results also clearly indicate that the engine running with biodiesel have slightly higher in-cylinder pressure and heat release rate than the engine running with normal diesel. The BSFC for the engine running with neat biodiesel was higher than the engine running with normal diesel by up to 15%. It is also noticed that the physical properties of the biodiesel affects significantly the performance of the engine.

“…Biodiesels used as alternative fuels in diesel engines reduce the emissions of hydrocarbons (HC), carbon monoxide (CO), sulfur oxide (SO 2 ), and PAHs (Antolin et al, 2002;Beer et al, 2002;Cardone et al, 2002;Durbin et al, 2002;Dorado et al, 2003;Kalam et al, 2003;Kalligeros et al, 2003;Goodrum and Geller, 2005;Hu et al, 2005;Legreid et al, 2007;Yuan et al, 2007;Chien et al, 2009;Pehan et al, 2009;Yuan et al, 2009;Tsai et al, 2010;. Previous studies and measurements of NO x emissions from biodiesel showed an increase in NO x emissions (Scholl and Sorenson, 1993;Graboski et al, 1996;Choi et al, 1997;Graboski and McCormick, 1998;Yoshimoto et al, 1999;McCormick et al, 2001;Grimaldi et al, 2002;Tat and Van Gerpen, 2003;Tat, 2004;Saravanan et al, 2010;Sun et al, 2010). The problem of high NO x emissions from biodiesel-diesel engines can be mitigated by the use of low-temperature combustion, reformulated biodiesel, selective catalytic reduction, and exhaust gas recirculation (Hess et al, 2007;Tsolakis et al, 2007;Muncrief et al, 2008;Tsolakis et al, 2008).…”

The development of biodiesels is being driven by the need for reducing emissions from diesel engines without modifying engines and for saving energy. The major obstacle to biodiesel commercialization is the high cost of raw materials. Biodiesel from waste cooking oil is an economical source and an effective strategy for reducing the raw material cost. Although biodiesels made from waste cooking oil have been previously investigated, PAH emissions from heavy-duty diesel engines (HDDEs) with catalyzer fueled with biodiesel from waste cooking oil and its blend with ultra-low sulfur diesel (ULSD) for the US-HDD transient cycle have seldom been addressed. Experimental results indicate that ULSD/WCOB (biodiesel made from waste cooking oil) blends had lower PM, HC, and CO emissions but higher CO 2 and NO x emissions when compared with that of ULSD. Using ULSD/WCOB blends instead of ULSD decreased PAHs by 14.1%-53.3%, PM by 6.80%-15.1%, HC by 6.76%-23.5%, and CO by 0.962%-8.65% but increase CO 2 by 0.318-1.43% and NO x by 0.384-1.15%. Using WCOB is an economical source and an effective strategy for reducing cost, and solves the problem of waste oil disposal.

-The article discusses the analysis of the influence of the connecting hole diameter on the amount of the mixture, flowing from the basic volume to the additional volume at the compression stroke in the prechamber engine. The resulting mathematical model allows one to accurately determine the amount of fresh charge, overflowing from the main combustion chamber into the secondary chamber at the compression stroke. The quantity of overflowing charge, taking into account the presence of throttling, allows one to determine the composition of the air-fuel mixture in the main and additional combustion chambers. Owing to the obtained results, it becomes possible to select the optimum mixture composition by adjusting the amount of fuel supplied. The experimental data on the immunity of the thermodynamic cycle of the upgraded engine to different sorts of fuels within a wide range of octane numbers and their viscosity by optimizing the air coefficient in the additional chamber without departing from the optimum ignition limits in all load conditions are given.
