“…At higher speeds, the power required to overcome friction increases at a higher rate, resulting in a slower increase in output power with a consequent increases in BSFC. This phenomenon has been largely documented by previous research [31], [9], [10], [32]- [34]. The main reason for higher BSFC for an engine running with biodiesel blends is mainly due to the low heating value of the biodiesel as discussed in Figure 3.…”

The heating value of fuel is one of its most important physical properties, and is used for the design and numerical simulation of combustion processes within internal combustion (IC) engines. Recently, there has been a significant increase in the use of dual fuel and blended fuels in compression ignition (CI) engines. Most of the blended fuels include biodiesel as one of the constituents and hence the objective of this study is to investigate the effect of biodiesel content to lower heating value (LHV) and to develop new LHV prediction models that correlate the LHV with biodiesel fraction, density and viscosity.Furthermore, this study also investigated the effects of the LHV on CI engines performance parameters experimentally. To achieve the above mentioned objectives density, viscosity and LHV of rapeseed oil biodiesel, corn oil biodiesel and waste oil biodiesel at different blend fraction values (B0, B5, B10, B20, B50, B75, and B100, where 'B5' denotes a blend of 5% biodiesel and 95% mineral diesel, etc) were measured as per EN ISO 3675:1998, EN ISO 3104:1996 and DIN 51900 standards. The engine experimental work was conducted on a four-cylinder, four -stroke, direct injection (DI) and turbocharged diesel engine by using rapeseed oil and normal diesel blends. Based on the experimental results, models were developed which have the capability to predict the 2 specific fuel consumption (BSFC) and thermal efficiency were analysed and it has been seen that for the neat biodiesel which its LHV is lower by 8% than diesel resulted in an increment of BSFC and thermal efficiency by 18% and 25% respectively.

“…In general, an increase of the injection pressure results in an increase in NO x emission and a decrease in soot emissions (Song et al 2012). Biodiesel influences significantly the fuel injection pressure; however, this influence is more exposed in MCFIS and less in ECFIS (Boudy and Seers 2009;Kegl 2006a;Kegl and Hribernik 2006;Luján et al 2009a, b;Payri et al 2012;Postrioti et al 2004;Tziourtzioumis and Stamatelos 2012;Zhang and Boehman 2007;Ye and Boehman 2012;Yoon et al 2009). …”

Özet: Biyodizel, dünyada kullanımı yaygınlaşan yenilebilir ve alternatif bir dizel yakıtıdır. Biyodizel üretiminde kullanılan alkol büyük önem arz etmekte ve üretilen biyodizelin yakıt özelliklerini doğrudan etkilemektedir. Farklı yakıt özellikleri, dizel motorlarda farklı yakıt enjeksiyon ve yanma karakteristiklerine sebep olabilmektedir. Bu nedenle bu çalışmada, metanol ve etanol kullanılarak üretilen iki farklı ester yakıtı ve saf motorin, common-rail yakıt enjeksiyon sistemine sahip bir dizel motorda üç farklı motor yükü (50 Nm, 100 Nm ve 150 Nm) ve 2000 dev/dk sabit motor devrinde deney yakıtı olarak kullanılmıştır. Bu yakıtların performans, yanma ve yakıt enjeksiyon analizi karşılaştırmalı olarak gerçekleştirilmiştir. Deney sonuçlarına göre, etil ve metil ester kullanımıyla özgül yakıt tüketimi (ÖYT) motorine kıyasla artış göstermiştir. Etil ve metil ester yakıtlarının silindir içi basıncı ve ısı yayılımı değerleri tüm deney şartlarında motorine kıyasla daha yüksek olmuştur. Yakıt enjeksiyon karakteristikleri, yakıt tipi ve motor yüküne bağlı olarak farklılık göstermiştir. Comparison of Performance, Combustion and Injection Characteristics of Methyl and Ethyl Ester Used In a Common Rail Diesel Engine KeywordsEthyl ester, Methyl ester, Injection, Combustion, Diesel engine Abstract: Biodiesel is a renewable alternative diesel fuel and its usage has become more popular in the world. The alcohol which is used in the biodiesel production is very important and it directly affects the fuel properties. Different fuel properties may cause different injection and combustion characteristics in diesel engines. Therefore, in this study, pure diesel fuel and two different esters produced via ethanol and methanol were used as test fuels in a common rail direct injection diesel engine under three different engine loads (50 Nm, 100 Nm and 150 Nm) and the constant engine speed (2000 rpm) test conditions. Detailed and comparative performance, injection and combustion analysis of these test fuels were done. According to the test results, brake specific fuel consumption (BSFC) increased with using ethyl and methyl ester compared with diesel fuel. Maximum in-cylinder pressure and heat release rate of ethyl and methyl ester were higher than those of diesel fuel for all test conditions. Fuel injection characteristics changed with the fuel type and engine load.
