“…It was found that the efficiencies of both energy and exergy were almost equal at higher operating loads. However, destructed exergy with biodiesel and the fumigation of gasoline were greater in biodiesel and fumigation [60].…”

The ever-increasing demand for transport is sustained by internal combustion (IC) engines. The demand for transport energy is large and continuously increasing across the globe. Though there are few alternative options emerging that may eliminate the IC engine, they are in a developing stage, meaning the burden of transportation has to be borne by IC engines until at least the near future. Hence, IC engines continue to be the prime mechanism to sustain transportation in general. However, the scarcity of fossil fuels and its rising prices have forced nations to look for alternate fuels. Biodiesel has been emerged as the replacement of diesel as fuel for diesel engines. The use of biodiesel in the existing diesel engine is not that efficient when it is compared with diesel run engine. Therefore, the biodiesel engine must be suitably improved in its design and developments pertaining to the intake manifold, fuel injection system, combustion chamber and exhaust manifold to get the maximum power output, improved brake thermal efficiency with reduced fuel consumption and exhaust emissions that are compatible with international standards. This paper reviews the efforts put by different researchers in modifying the engine components and systems to develop a diesel engine run on biodiesel for better performance, progressive combustion and improved emissions.

“…Compression ignition engines are widely used in industry and transportation due to their higher fuel economy, durability and specific power output. On the other hand, these engines are the major sources of nitrogen oxides and particulate matter (PM) emissions [1][2][3]. Research works are aimed at creating a high performance engine with low exhaust gas emissions.…”

“…The results showed that gasoline fumigation increases the energy and exergy efficiency. The main conclusion was that the combination of biodiesel and gasoline fumigation might be used as a substitute for diesel fuel in diesel engines under high loads, with higher exergy efficiency and lower exhaust exergy losses [1].…”

This paper presents results of investigation of co-combustion process of biodiesel with gasoline, in form of mixture and using dual fuel technology. The main objective of this work was to show differences in both combustion systems of the engine powered by fuels of different reactivity. This paper presents parameters of the engine and the assessment of combustion stability. It turns out that combustion process of biodiesel was characterized by lower ignition delay compared to diesel fuel combustion. For 0.54 of gasoline energetic fraction, the ignition delay increased by 25% compared to the combustion of the pure biodiesel, but for dual fuel technology for 0.95 of gasoline fraction it was decreased by 85%. For dual fuel technology with the increase in gasoline fraction, the specific fuel consumption (SFC) was decreased for all analyzed fractions of gasoline. In the case of blend combustion, the SFC was increased in comparison to dual fuel technology. An analysis of spread of ignition delay and combustion duration was also presented. The study confirmed that it is possible to co-combust biodiesel with gasoline in a relatively high energetic fraction. For the blend, the ignition delay was up to 0.54 and for dual fuel it was near to 0.95.

“…In another study, Sekmen et al [28] employed the first and second Laws of thermodynamics to study exergy and energy in a four-cylinder, direct injection diesel engine which had been fuelled by blends of diesel and biodiesel. Hoseinpour et al [29] studied the exergy and energy balance in a direct injection diesel engine which was fuelled by diesel/biodiesel/gasoline fuel blends. Based on results the maximum exergy of engine was in case of using the combination of B20 and gasoline fumigation.…”

Biodiesel, as the main alternative fuel to diesel fuel which is produced from renewable and available resources, improves the engine emissions during combustion in diesel engines. In this study, the biodiesel is produced initially from waste cooking oil (WCO). The fuel samples are applied in a diesel engine and the engine performance has been considered from the viewpoint of exergy and energy approaches. Engine tests are performed at a constant 1500 rpm speed with various loads and fuel samples. The obtained experimental data are also applied to develop an artificial neural network (ANN) model. Response surface methodology (RSM) is employed to optimize the exergy and energy efficiencies. Based on the results of the energy analysis, optimal engine performance is obtained at 80% of full load in presence of B10 and B20 fuels. However, based on the exergy analysis results, optimal engine performance is obtained at 80% of full load in presence of B90 and B100 fuels. The optimum values of exergy and energy efficiencies are in the range of 25-30% of full load, which is the same as the calculated range obtained from mathematical modeling.
