Currently, our global environment has been affected due to the air pollution caused by many sectors (such as automotive, industrial, transportation) in higher magnitudes. Many environmentalists, scientists, researchers and engineers have contributed their efforts to eradicate the air pollution. It is well known noted that most of the harmful pollutants were evolved from diesel engine power engines/plants. Considering the objective of enhancing performance and reducing harmful emissions of diesel engine, the current research work has been conducted on mixing DEE (Di-Ethyl Ether) and normal water with normal diesel fuel in definite quantities. Five stages of investigations were carried out to perform the task of blending water and DEE with the normal diesel fuel. In the first stage, to obtain the baseline readings, normal diesel fuel was experimented in a light duty constant speed diesel engine. Normal water (2% & 4% by vol.) was combined with the normal diesel fuel with the aid of emulsifiers (Span80 & Tween80) and mechanical stirrer (speed of 3000 rpm) to obtain the water blended diesel emulsion fuels in the second stage. In the third stage, DEE was mixed with water-emulsion fuels which were prepared in the second stage. The stability and properties of fuels was determined in the fourth stage. In the fifth stage, the prepared stable DEE-water-diesel emulsion fuels were tested in a light duty constant speed diesel engine generator and eventually compared to those readings of normal diesel fuel. Experimental outcome from all the tested fuels revealed that water and DEE mixed emulsion fuels reflected better performance and reduced harmful emission attributes.

Fossil fuels are exhausting quickly because of incremental utilization rate due to increase population and essential comforts on par with civilization. In this connection, the conventional fuels especially petrol and diesel for internal combustion engines, are getting exhausted at an alarming rate. In order to plan for survival of technology in future it is necessary to plan for alternate fuels. Further, these fossil fuels cause serious environmental problems as they release toxic gases into the atmosphere at high temperatures and concentrations. The predicted global energy consumption is increasing at faster rate. In view of this and many other related issues, these fuels will have to be replaced completely or partially by less harmful alternative, eco-friendly and renewable source fuels for the internal combustion engines. Hence, throughout the world, lot of research work is in progress pertaining to suitability and feasibility of alternative fuels. Biodiesel is one of the promising sources of energy to mitigate both the serious problems of the society viz., depletion of fossil fuels and environmental pollution. In the present work, experiments are carried out on a Single cylinder diesel engine which is commonly used in agricultural sector. Experiments are conducted by fuelling the diesel engine with bio-diesel with LPG through inlet manifold. The engine is properly modified to operate under dual fuel operation using LPG through inlet manifold as fuel along FME as ignition source. The brake thermal efficiency of FME with LPG (2LPM) blend is increased at an average of 5% when compared to the pure diesel fuel. HC emissions of FME with LPG (2LPM) blend are reduced by about at an average of 21% when compared to the pure diesel fuel. CO emissions of FME with LPG (2LPM) blends are reduced at an average of 33.6% when compared to the pure diesel fuel. NOx emissions of FME with LPG (2LPM) blend are reduced at an average of 4.4% when compared to the pure diesel fuel. Smoke opacity of FME with LPG (2LPM) blend is reduced at an average of 10% when compared to the pure diesel fuel.

Substitution ratio is an important parameter influencing on the performance of dual-fuel engine. In order to study the effects of substitution ratio on the emission characteristics of diesel/ methanol dual-fuel engine, a 6-cylinder turbocharged diesel engine was converted into a dual-fuel engine fueled with pilot diesel fuel and methanol. Methanol was injected into the intake pipe and ignited by pilot diesel fuel. Experiments were performed at a constant speed of 1400 r/min, and at three different engine loads of 40%, 60% and 100%. The experimental results indicate that CO and HC emissions of dual-fuel mode both increase significantly with the increase of substitution ratio, and are higher than those of diesel mode. Compared to diesel mode, dual-fuel mode generates lower NOx and smoke emissions. In addition, as substitution ratio increases, NOx and smoke emissions are decreased.

Diesel Emissions

This research work investigates diesel combustion and exhaust emissions with additives addition to conventional diesel fuel in a four-stroke naturally aspirated direct injection (DI) diesel engine. The additives include DGM, and liquid cerium. The results show that with the addition of DGM to diesel fuel, brake specific energy consumption (BSEC) and all diesel emissions are significantly reduced. The volumetric blending ratios of additives to diesel fuel are 0, 25, 50, 75 and 100%. All emissions including smoke emissions decrease with the increase in oxygen content in the fuel and it is noted that smoke emission completely disappeared at an oxygen content of 36 wt–%. The reason for improvement in BSEC with the addition of additives to base diesel fuel is the improvement of degree of constant volume combustion, and the reduction of the cooling loss. Engine noise and odor concentrations are remarkably reduced with diesel-additive blends. Significant improvement in BSEC and exhaust emissions is not only found at medium load condition but also at high load condition. Key words: Diesel engine, DGM, emissions, BSEC, and cooling loss

Using biodiesel in diesel engines is beneficial for reducing emissions of carbon monoxide (CO), hydrocarbons (HC) and particulate matters (PM). Biodiesel is usually produced from vegetable oils or animal fats. When produced from plant oil or woody plant sources, biodiesel can reduce a significant amount of carbon dioxide on a life cycle basis. The objective of this study is to produce biodiesel from a non-conventional woody plant source that is, crude tall oil, which is a dark brown viscous liquid extracted and processed in wood pulping plants. It contains a high percentage of fatty acids. From raw crude tall oil, tall oil fatty acids were separated and were successfully used for the production of biodiesel in this study. Although biodiesel produces lower CO, HC and PM than petroleum diesel fuel, it produces higher oxides of nitrogen (NOx) emissions in diesel engines. Water emulsifications of diesel-biodiesel blends are investigated in a direct injection (DI) diesel engine in this work to understand their potential for NOx reduction. When using 10% water in the emulsions, NOx was reduced by nearly 15%. In aldehyde emissions, B100 showed 35% lower aldehydes and B100 with 10% water emulsion produced nearly 90% lower aldehydes than diesel fuel - a substantial reduction. Therefore, this study accomplished the desired goal of producing biodiesel from a non-conventional source, which satisfies ASTM biodiesel standard and results in lower NOx and aldehydes emissions with water emulsifications of diesel-biodiesel blends in a diesel engine compared to that of diesel fuel.

Many alternative fuels have been introduced in the fuel market in the recent years. But, still there is a lot of research work going on around the world in the conversion of waste substances into useful energy. Some of the researchers show a remarkable interest in using pyrolysis oil as an alternative fuel for diesel engines. Tire pyrolysis oil (TPO) from waste automobile tires has been found to be an energy source. It could be blended with diesel fuel and used as an alternative fuel for diesel engines. But, it cannot be used as the sole fuel in diesel engines due to its poor ignition quality. Diethyl ether (DEE) is a good ignition improver having a cetane number of more than 125. In the present investigation, two different blends of Tire pyrolysis oil and DEE (with addition of DEE at 0.5 and 1%) were used in a single cylinder four stroke water cooled direct injection diesel engine developing a rated power of 3.7 kW at 1500 rpm. The engine was able to run with 100% Tire pyrolysis oil with a maximum DEE addition of 1%. Results indicated that nitric oxide emission reduced by about 4% with an 8% increase in smoke emission at full load when the engine was fueled with TPO and 1% of DEE compared to that of diesel fuel operation. The brake thermal efficiency of the engine fueled with TPO-DEE blends was found to be lesser than that of diesel operation at full load. Brake specific energy consumption was also found to be higher with TPO DEE blends compared to that of diesel fuel operation. The results of the performance and emissions of the DI diesel engine are presented in this paper.
