“…Therefore, HRR values of both WB and WBE are higher than cDF. Patel et al [10], Alptekin et al [30] and Jamrozik et al [31] have also similar results in their studies. The similar studies on combustion analyses of WB, bioethanol and CI in diesel engines are presented in Table 6.…”

In this study, bioethanol produced from sugar beet and biodiesel produced from waste cooking oils was blended with each other in the volumetric rates to be 20% and 80%, respectively. Cetane improver (di-tert-butyl peroxide) was added into blend fuel in 1-2-3% as volumetric. The obtained blends were used as a fuel in the diesel engine which is single-cylinder, directinject, four-stroke. The tests were conducted under four different engine loads (25%, 50%, 75% and 100%) and 1400 rpm engine speed. The test results showed that brake-specific fuel consumption was decreased up to 15.5% thanks to the addition of cetane improver, although biodiesel and bioethanol increased brake-specific fuel consumption by 16.1% and 27.54%, respectively. However, brake thermal efficiency values were increased up to 9.44% with both biodiesel and cetane improver added blend fuels, while brake thermal efficiency was decreased by 3.88% with bioethanol addition. The more compatible combustion characteristics with that of diesel fuel have been obtained due to especially the increase in cetane number. The use of biofuels increased both maximum cylinder pressure and heat release rate. While, with the cetane improver addition, a decrease in CO, HC and smoke opacity values was observed up to 22.5%, 17.44% and 24.44%, respectively, CO 2 , NO X and exhaust gas temperature values were increased up to 19.55%, 5% and 15.22%, respectively, according to bioethanol blend fuel.

The transport vehicles have been using the internal combustion engine for many decades. The internal combustion engine is used because of their high reliability. The transport sector plays a vital role in the country’s economy. It is estimated that about 90% of the transportation sector uses fossil fuels. With the increasing industrialization, there will be a shortage of fossil fuels. Every year there is an increase in the energy demand by 2%, stated by International Energy Agency Report. There would be 39% increase in the greenhouse gas emission by the year 2030 from fossil fuels. With the rising concern about climate change and the increasing amount of toxic emissions, manufacturers of the car are getting aware and are shifting towards less polluting vehicles or green vehicles. Biodiesel is also gaining interest and is being preferred because of its continued availability, emission characteristics showed that biodiesel have low CO emission. With addition of ethanol the emission of CO further decreases but NOx emission increases. NOx decreased with jatropha methyl ester & 50% turpentine oil. On the other hand use of electric vehicle or hybrid electric vehicle would also decrease the emission by 51% but would increase the load on power grid by 3% for every 30% penetration. Which would increase the emission/air pollution from the thermal power plant. Emission in the human body can cause illness, increase the death of can be hazardous to the health of humans. This paper gives a review of the emissions from biodiesel and electric vehicles and the health effects

“…Blends of Karanja oil up to 50% on single cylinder compression ignition engine at various pressures have indicated slight improvement in BTE and 20% of higher NO x than the diesel [13]. Formation of carbon deposits were found with pyrolytic biodiesel, which also shows improved BTE at 30% blend [14]. Biodiesels of animal fat extraction have given remarkable reductions in emissions except NO X [15].…”

Hazardous pollutants and limited sources of fossil fuels made power dependent sectors to focus on alternative sources. However, complete replacement is still constrained and challenging. Attempts to assure complete replacement were more or less fulfilled by biodiesels. In this article, trials made on EGR associated single cylinder CRDI engine with blends of Jatropha and Rice-bran biodiesels are discussed. Set of readings obtained under the split injection system of mass 10% pilot fuel and 90% main fuel maintained at 300 bars with dwell of 10 o and 15% of cold EGR are examined. Results obtained show, brake thermal efficiency is higher at peak load for RJD-II sample than RJD-I sample, whereas specific fuel consumption is same. Sample RJD-I has indicated highest break mean effective pressure at full load which influenced mechanical efficiency. Remarkable changes observed in emissions indicate 11.7% and 16.6% reduction in CO for RJD-I and RJD-II, respectively. NO x discharge reduced up to 5.5% and 7.7% for RJD-I and RJD-II, respectively. CO 2 products are 6.6% and 8.6% higher for RJD-I and RJD-II respectively than diesel.
