“…The CO2 emissions for all fuel blends were less than that of diesel. This concurs with results obtained by Dubey and Gupta [49]. This is attributed to the fact that biodiesels are low carbon fuels and have a lower elemental carbon to hydrogen ratio than diesel [47,50].…”

In this study, 18 soapnut biodiesel-diesel blends along with soapnut oil as an additive in some blends were prepared and used in a diesel engine to investigate the effect of oxygen content in the fuel blends on engine performance and emission characteristics. Considering the large variations in the oxygen content of these fuel blends, the obtained results were demonstrated based on varying fuel oxygen content. Findings showed that the best engine performance was achieved with a fuel oxygen content in the range of 1.8%-3.0%, whereas the best engine emissions were obtained with a fuel oxygen content in the range of 0.71%-2.37%. Hence, considering both engine performance and emissions, the optimal zone of fuel oxygen content was found to be in the range of 1.80%-2.37%. Thus, it can be concluded that biodiesel blended fuels having an oxygen content in the aforesaid range can be successfully used in diesel engines with comparable engine performance and emissions to those using diesel fuel. Nevertheless, further research is required to reduce the fuel oxygen content to this optimal range if the blends consist of higher biofuel components. Besides that, the use of suitable additives in the biodiesel blended fuels may be a viable option to achieve the said purpose, which needs further research.

The most important advantage of biogas is that one can retrofit easily the conventional combustion engines to be used for the new fuel but remain the problem of pollutant emission. In this paper, the effect of the biogas composition on the emissions of CO and NOx in an SI engine is investigated numerically. Three compositions were studied (CH4:40 %, CO2:60 %), (CH4:50 %, CO2:50 %), (CH4:60 %, CO2:40 %), at equivalence ratio (ϕ) from lean to rich. The non-adiabatic partially premixed combustion model with probability density function (PDF) method and Zimont model of the turbulent flame speed are used. It was found that increasing CO2 in the biogas lowers NOx emissions significantly, whereas, CO was found to be very low, and appears only at high CH4 concentration. A biogas with (CH4:60 %, CO2:40 %), burning at about (ϕ = 0.9), i.e. slightly lean mixture, and advanced spark timing (between 10 to 20°.) seems to be a very a realistic combination in terms of biogas composition, stoichiometry and spark timing. It is recommended that, to accomplish some upgrading, in case of biogases with low CH4 percentage, to get it up to 60 %.

“…Using catalysts in the reaction between VOs or AFs and methanol, 2-propanol, ethanol, and buthanol was carried out for transesterification. The transesterification was potential and cheap method of transforming bio-oils with the large structure and non-straight-chain molecules into smaller structure, straight-chain molecules aiming at meeting the requirement of fuel standard for diesel engines [8]. The biodiesel properties such as viscosity, cloud point, heat of combustion, volatility were similar to diesel fuel.…”

Alternative fuel and renewable energy is becoming important issue due to unstable fuel supply and price. Recently, bio-fuels are much interested because of their beneficial effects on environment, agriculture and economic development. Raw vegetable oils -a kind of bio-fuels, even though it has many disadvantages, are potential renewable fuel replaced for ever-exhausted fossil fuel. In this work, vegetable oil available in the South of Vietnam such as raw coconut oil is used by heating up to aim at reducing its high viscosity, surface tension, density and meeting the fuel requirements. Experimental and comparative study is carried out on an 80 hp small marine diesel engine fueled with heated coconut oil (HCO) and fossil diesel fuel. The results of engine performance and emission characteristics are measured. The results show that, specific fuel consumption, CO, HC and smoke emissions are higher, but thermal efficiency and NOx emission are lower as using HCO in comparison with diesel fuel. Besides, this study also denotes that, heated raw coconut oil up to 100 o C is considered as the most proper fuel to achieve the engine performance and emission characteristics, which are equal to diesel fuel.
