Due to the world’s growing population, the size of areas intended for food production in many countries of the world can only be achieved through severe environmental damage and deforestation, which has many other detrimental consequences in addition to accelerating global warming. By replacing the bio-content of fuels with other alternative fuels, land that is used for energy crops can also be used to grow food, thus mitigating the damaging effects of deforestation. Waste-based tire pyrolysis oil (TPO) can be a promising solution to replace the bio-proportion of diesel fuel. Since it is made from waste tires, it is also an optimal solution for recycling waste. This research shows the effect of different low-volume-percent tire pyrolyzed oil blended with diesel on the performance, fuel consumption, and emissions on a Mitsubishi S4S-DT industrial diesel engine. Four different premixed ratios of TPO were investigated (2.5%, 5%, 7.5% and 10%) as well as pyrolysis oil and 100% diesel oil; however, the following studies will only include the data from the pure diesel and the 10% TPO measurements. The experimental investigations were in an AVL electric dynamometer, the soot measurements were in an AVL (Anstalt für Verbrennungskraftmaschinen List) Micro soot sensor (MSS), and the emission measurements were in a AVL Furier-transform infrared spectroscopy (FTIR) taken. The scope of research was to investigate the effect of low volume percentage TPO on performance and emissions on a light-duty diesel engine.

Compression Ignition Engine

Diesel engines are principally employed in industries, transportation and agricultural fields because of their high efficiency and reliability. However, too much of smoke and nitric oxide emissions is one of the drawbacks. To regulate pollution and other negative effects of diesel engines, alternative fuels have come into existence. Ethanol produced from sugarcane in the biomass process is a recent example of it, due to its high octane number. But using raw ethanol is not a quality fuel for a solid ignition engine. It can be converted through a dehydration process to produce Diethyl Ether (DEE), which is an excellent compression-ignition fuel with a higher energy level than ethanol. DEE having a starting problem can’t be used directly in large amounts in diesel engines, but using it in small amounts is an advantage. This paper highlights the performance of blended pyrolysis oil with diesel fuel in the combination of DEE used in a mono cylinder four-stroke diesel engine. The pyrolysis process was used to extract the pyro oil from the Mosambi peel biomass. The oil has been extracted from Mosambi peel at the reaction temperature of 750˚C, in other words, the fast pyrolysis process. The study was conducted on composition of MDEE5 (5%MPPO+5%DEE+90D),MDEE10(10%MPPO+5%DEE+85% D) and MDEE15 (15% MPPO + 5%DEE + 80% D). Characteristics of the above combinations, MDEE5, MDEE10, and MDEE15 were analyzed and the properties like viscosity, density, flashpoint, fire point FTIR analysis of oils are also recorded. The blending of pyrolysis oil and DEE are mixed with diesel fuel with its volume. All the blended fuels were tested at 1500 rpm single-cylinder diesel engine. The maximum power output of brake thermal efficiency was recorded as 31.5% with MDEE5 as it was 30.0% with BD. The emission of smoke and NOx were considerably reduced

The Impact

Experimental work was done to examine the impact of diesel fuel with alumina nanoparticles on combustion characteristics, emissions and performance of diesel engine. Alumina nanoparticles were mixed with crude diesel in various weight fractions of 20, 30, and 40 mg/L. The engine tests showed that nano alumina addition of 40 ppm to pure diesel led to thermal efficiency enhancement up to 5.5% related to the pure diesel fuel. The average specific fuel consumption decrease about neat diesel fuel was found to be 3.5%, 4.5%, and 5.5% at dosing levels of 20, 30, and 40 ppm, respectively at full load. Emissions of smoke, HC, CO, and NOX were found to get diminished by about 17%, 25%, 30%, and 33%, respectively with 40 ppm nano-additive about diesel operation. The smaller size of nanoparticles produce fuel stability enhancement and prevents the fuel atomization problems and the clogging in fuel injectors. The increase of alumina nanoparticle percentage in diesel fuel produced the increases in cylinder pressure, cylinder temperature, heat release rate but the decreases in ignition delay and combustion duration were shown. The concentration of 40 ppm alumina nanoparticle is recommended for achieving the optimum improvements in the engine’s combustion, performance and emission characteristics.

Increasing industrialization and motorization led to a significant rise in demand of petroleum products. As these are the non-renewable resources, it will be troublesome to predict the availability of these resources in the future, resulting in uncertainty in its supply and price and is impacting growing economies like India importing 80% of the total demand of the petroleum products. Many attempts have been made by different researchers to find out alternate fuels for Internal Combustion engines. Many alternate fuels like Biodiesel, LPG (Liquefied Petroleum Gas), CNG (Compressed Natural Gas) and Alcohol are being used nowadays by different vehicles. In this context pyrolysis of scrap tyres can be used effectively to produce oil, thereby solving the problem of waste tyre disposal. In the present study, Experimental investigations were carried out to evaluate the performance and emission characteristics of a single cylinder diesel engine fueled by TPO10, TPO15, and TPO20 at a crank angle 280 before TDC (Top Dead Centre) and injection pressure of 180 bar keeping the blend quality by controlling the density and viscosity of tyre pyrolysis oil within permissible limit of euro IV diesel requirement. The performance and emission results were analyzed and compared with that of diesel fuel operation. The results of investigations indicate that the brake thermal efficiency of the TPO - DF blend decreases by 4 to 8%. CO emissions are slightly higher but within permissible limit of euro IV emission standards. HC emissions are higher by about 40 to 60% at partial load whereas smoke opacity is lower by about 14% to 22% as compared to diesel fuel.

Emulsified Fuel

Diesel engines are employed as the major propulsion power sources because of their simple, robust structure and high fuel economy. It is expected that diesel engines will be widely used in the foreseeable future. However, an increase in the use of diesel engines causes a shortage of fossil fuel and results in a greater degree of pollution. To regulate the above, identifying an alternative fuel to the diesel engine with less pollution is essential. Ethanol–diesel emulsion is one such method, used for the preparation of an alternative fuel for the diesel engine. Experimental investigations were carried out to compare the performance of diesel fuel with different ratios 50D: 50E (50 per cent diesel No: 2: 50 per cent ethanol –100 per cent proof) and 60D: 40E emulsified fuels. In the next phase, experiments were conducted for the selected emulsified fuel ratio 50D: 50E for different high injection pressures and the results are compared. The results show that for the emulsified fuel ratios, there is a marginal increase in torque, power, NO x, emissions, and decreasing values of carbon monoxide (CO), sulphur dioxide (SO2) emissions at the maximum speed conditions, compared with diesel fuel. Also, it is found that an increase in injection pressure of the engine running with emulsified fuel decreases CO and smoke emissions especially between 1500 to 2000 r/min with respect to the diesel fuel.

Moringa Oil

World at present is confronted with the twin crisis of fossil fuel depletion and environmental pollution. Rapid escalation in prices and hydrocarbon resources depletion has led us to look for alternative fuels, which can satisfy ever increasing demands of energy as well as protect the environment from noxious pollutants. In this direction an attempt has been made to study a biodiesel, namely Moringa Oil Methyl Esters [MOME]. All the experiments were carried out on a 4.4 kW naturally aspirated stationary direct injection diesel engine coupled with a dynamometer to determine the engine performance and emission analysis for MOME. It was observed that there was a reduction in HC, CO and PM emissions along with a substantial increase in NOx. MOME and its blends had slightly lower thermal efficiency than diesel oil.

Viable Solution

The progressive diminution of the oil reserves all over the world highlights the necessity of using alternative fuels derived from durable renewable resource. The use of the alternative fuels represents a viable solution to reduce the pollutant emissions and to replace fossil fuels. Thus, a viable solution is the use of the animal fats in mixture with the diesel fuel at the diesel engines. A D2156 MTN8 diesel engine was firstly fuelled with diesel fuel and then with different blends of diesel fuel-animal fats (5% and 10% animal fats content). In the paper are presented some results of the experimental investigations of engine fuelled with preheated animal fats. The raw animal fats effects on the combustion process and on the pollutant emissions at different engine loads and 1450 rev/min engine speed are showed. The engine cycle variability increases at the animal fats content increase. The cycle variability for maximum pressure, maximum pressure angle and indicated mean effective pressure is analysed. The cycle variability coefficients values don’t exceed the recommended values of the standard diesel engine.

Petroleum Reserves

Random extraction and consumption of fossil fuels have leads to a reduction in petroleum reserves. As for as developing countries like India is connected the need to search for alternative fuels is most urgent as India is heavily dependent upon the import of petroleum to meet its demands for automotive and power sectors. This has inspired curiously in alternative sources for petroleum based fuels. An alternative fuel must be economically competitive and environmentally acceptable. India has great potential for production of biofuels like Biodiesel from vegetable seeds. In the quest to find an alternative to the existing diesel and petrol fuels various Biodiesel and alcohol has been tried and tested in the Internal Compression engine. In this direction, an attempt has been made to investigate the performance and emission characteristic of Biodiesels and compare it with diesel. The Biodiesels considered are Tamanu, Mahua and Pongamia were tested with four stroke diesel engine. A drastic improvement in reduction of Hydrocarbon (HC) and Carbon monoxide (CO) were found for Biodiesels at high engine loads. Smoke and Nitrogen oxides (NOx) were slightly higher for Biodiesels. Biodiesels exposed similar combustion stages to diesel fuel. Therefore use of transesterified vegetable oils can be partially substituted for the diesel fuel at most operating conditions in term of the performance parameters and emissions without any engine modification.

In the present work on unheated Corn oil methyl ester and Preheated Corn oil methyl ester is used to prepare different concentration blends with diesel, B20, B40 and B60 were used as alternative fuels in a compression ignition engine. The properties like calorific value, flash point, fire point and viscosity of these oils were determined. The viscosity of corn oils has been reduced through transterification process. The waste heat energy from the exhaust gas was reused to preheat the corn oil around 80°C by adjusting the flow rate of exhaust gas.  The performance and emission characteristics of a single cylinder, direct injection diesel engine were determined using unheated corn oil, Preheated Corn oil and diesel. Brake thermal efficiency of preheated B20 was more than other blends and unheated fuels but equal to diesel fuel. Brake specific fuel consumption, CO2 and HC of preheated B20 were less than unheated fuels and diesel. However, the NOx emission of preheated B20 was little higher than unheated fuels and diesel due to high combustion temperature. By considering the result of all the factors, preheated B20 blend was found to be a suitable alternative for diesel fuel.

Alternative fuels available at low cost, friendly to natural environments and meet the energy needs and demands, have witnessed a growing demand and use today. Ethanol is an attractive renewable energy source with a high content of oxygen. Ethanol can be produced through ethanolisis, however for this work direct blending of conventional diesel, waste plastic pyrolysis oil and ethanol with commercial fuel improver CI-0808 purchased from Innospec company was attempted. The primary purpose of adding a cetane improver was to improve the combustion characteristics of the blends by at least 1- 3 ignition quality points. Five mixing ratios were chosen in the following order, 50:25:25, 60: 20:20, 70: 15:15, 80: 10:10 and 90: 5:5 for Waste Plastic Pyrolysis Oil (WPPO), ethanol and conventional diesel (CD) respectively. However, for the fuel additive mixing ratio the total volume percentage was considered and the ratio put at 0.01% of the total quantity of blended fuel. In this work WPPO, diesel blends and fuel additives improvers were used as alternative fuel. This was to evaluate their performance and emission characteristics in a stationary single cylinder water cooled experimental diesel engine. The CI-0808 was added due to its potential power to reduce emissions of CO, UHC, NOX, PM and improved engine performance. The results obtained were compared carefully to ASTM standards and discussed using graph curves figures and tabulated values. The conclusion was that ethanol and WPPO blends can be used in diesel engines as alternative fuel without modification. Used in combination with cetane improvers the emissions reduce significantly and performance improved equalling that of conventional diesel fuel.
