“…According to Rakopoulos DC [37], the nitrogen oxides emissions reduced for diesel-ethanol emulsified fuel and gradually decreases with increasing percentage of ethanol in the fuel blend. Combustion temperature and oxygen content inside engine cylinder are two major reason for NOx formation [53]. This decrement of NOX emissions occurs because of temperature reducing effect of ethanol due to its lower calorific value and it is gradually decreasing with ethanol concentration.…”

CI engine is an important and widely used engine in the power generation industries generally fuelled by diesel. The use of CI engine vehicles is increasing continuously day by day which in turns diesel fuel consumption and engine emissions increases. Limitation of these conventional fuel as well as continuously increasing global warming by engine emissions has motivated to researchers in the field of alternative renewable fuel source like biofuel such as biodiesel, methanol, ethanol etc. Ethanol is the most commonly researched alcoholic fuel as alternative fuel. The objective of this study is to investigate the effect of ethanol-diesel fuel blend on engine performance such as BSFC, BTE, brake power, brake torque as well as engine emission parameters such as NOx, CO, HC, exhaust gas temperature etc. of a CI engine. Through this study it was found that ethanol significantly reduces HC, PM, NOx and exhaust gas temperature but slightly increases fuel consumption. Also, ethanol additive enhanced engine performance like BTE, brake power and brake torque. The outcomes of this study may help for researchers to understand the effect of ethanol addition on engine performances and emissions at different ethanol-diesel fuel blend concentration for CI engine.

“…They discovered that there was a 51% reduction in smoke emission with the fumigation method, and a 32% reduction in smoke emission with the emulsion method. Sandalci et al [27] investigated the effects of different proportions of ethanol-diesel blends with emulsions on performance and emissions. They reported that as the ethanol ratio in the blend increased, the smoke emission decreased, but the CO emissions increased.…”

In this research, as the first stage, the effects of the ethanol on engine performance and emissions under the fumigation and emulsion method were experimentally investigated under part load and various engine speed conditions. Diesel-ethanol blend containing 5% ethanol by volume was used as the mixture fuel. In the fumigation method, ethanol was used at the same rate and 99.9% purity as the emulsion method. As the second stage, the effects of ethanol post injection on engine performance and pollutant emissions were investigated in the experimental engine modeled in AVL Boost simulation program and compared with the experimental results. Simulation post injection tests were performed separately after the main injection at 3 CA (P1) and 7 CA (P2) crank angles. In the experimental studies, NOx emission decreased with the emulsion method (E5) at low and high engine speeds. In post injection strategies, NOx emission in general increased due to improved combustion and increased in-cylinder temperature with P1 (first post injection) and P2 (second post injection) strategies. Soot emission decreased significantly with E5. This improvement in soot emissions was approximately 87% in post injection strategies.

“…The ethanol use on compression ignition engines by direct injection into the combustion chamber, by blends method, is limited due to low density, low viscosity, and because the cetane number is insufficient [15]. Without modifying the engine structure, the limit of 15% ethanol mixed with diesel oil is indicated, in a volumetric ratio (v/v) [25]. For using ethanol in diesel engines, typically, it applies the fumigation method [26].…”

“…Chauhan et al [15] and Sandalci et al [25] cite that among the methods used for ethanol use on diesel engine, fumigation is the more studied, for enabling the higher diesel substitution rate by ethanol, in energy terms (up to 50%), and for requiring fewer changes on the engine physical structure. Besides the use of commercial ethanol, with low water concentration, in recent years, studies have been carried out aiming to characterize the use of ethanol with high water concentrations (wet ethanol) on spark ignition engine [27][28][29][30] and compression ignition engines.…”

New techniques for the use of renewable fuels have been proposed by researchers around the world, seeking to reduce our dependence on fossil fuels and emissions of harmful gases. For compression ignition engines, fumigation stands out for allowing more significant replacements than other dual-fuel techniques, and also for not requiring modifications to the original engine structure. In this context, wet ethanol has emerged as one of the most viable fuels for port fuel injection due to its low reactivity and its renewable origin. This paper investigates the effects caused on the compression ignition engine by the use of diesel oil and wet ethanol by fumigation method and an air restriction in the engine intake through a throttle. The used engine was a small single-cylinder, coupled to an alternator, with constant load and engine speed. The fumigation fuel was wet ethanol with four different water concentrations, and different fractions of diesel oil substitution were tested. The results indicated that the use of ethanol and wet ethanol by the fumigation method increases conversion efficiency by up to 10% compared to the baseline test. However, the reduction in the intake airflow always causes a decrease in this efficiency. Intake air throttled also provided an increase in exhaust gas opacity compared to the free airflow conditions, but it is reduced when compared to the baseline test. Concerning specific emissions, carbon monoxide has higher emission levels when ethanol fumigation is used compared to the baseline condition. Under the same conditions, nitrogen oxide emissions are reduced.
