Performance studies of Tire Pyrolysis Oil blends with Diesel Fuel
2015
The present rate of consumption of gasoline would lead to severe shortage of it within next few decades. An urgency of finding an alternative fuel in its place has led to several researches around the world. In this study oil obtained from pyrolysis of waste tire was studied upon for its suitability to be used with diesel fuel. A study was carried out to evaluate the use of various tire pyrolysis oil (TPO) blends with diesel fuel. Performance and emission characteristics of TPO blends with diesel on a 4 cylinder direct injection engine are presented in this study. In the initial stage the test were conducted on four stroke single cylinder diesel engine by using diesel and base line data was generated.A constant speed off 1500rpm was maintained throughout the experiment. Then commercially available TPO was blended with diesel fuel at the volumetric ratios of 5 % ( D5), 10 % (D10) and15 % ( D15).The results showed that brake thermal efficiency of the engine was maximum for D10 blend t...
Experimental Investigation of Single Cylinder Diesel Engine using Tyre Pyrolysis Oil (TPO) Blends
— 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 tires can be used effectively to produce oil, thereby solving the problem of waste tire 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 26 0 before TDC (Top Dead Centre) and injection pressure of 190 bar keeping the blend quality by controlling the density and viscosity of tire 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 2 to 3%. CO emissions are well within permissible limits. HC emissions are higher by about 20 to 40% at partial load whereas smoke opacity is lower by about 20 to 30% as compared to diesel fuel.
WASTE PYROLYSIS TIRE OIL AS ALTERNATIVE FUEL FOR DIESEL ENGINES
Today, India is facing two biggest problems, one is the depletion of the fossil fuel reservoir and the other is the pollution. These two problems motivated us, as well as many other researchers, to work on the utilization of non biodegradable material. Scrap tyre consists of organic matter, that is often disposed illegally in open lands, ultimately causing an environmental problem. Pyrolysis is considered as a useful technique, for recycling of scrap tyres by using which liquid, gases, carbon black and steel wires are obtained. Tire-derived oils can be used as fuel or added to conventional fuels, producing fuel blends with improved properties and reduced cost. Pyrolysis of scrap tyre starts at 250 °C and gets completed at 550 °C. The properties of the Tyre pyrolysis oil, was compared with the petroleum products and found that, it can also be used as a fuel for diesel engine. Experimental Investigations will examine the use of blended fuel (i.e., TPO with Pure Diesel), in different ratios in single cylinder, four stroke VCR diesel engines. Performance characteristics like Efficiencies and Powers were calculated at various loads conditions, at constant speed. It was found that, the blends of pyrolysis tire oil (TPO) of waste tire can efficiently be used in diesel engines, without any engine modifications.
The use of tyre pyrolysis oil in diesel engines
Tests have been carried out to evaluate the performance, emission, and combustion characteristics of a single cylinder direct injection diesel engine fueled with 10%, 30%, and 50% of tyre pyrolysis oil (TPO) blended with diesel fuel (DF). The TPO was derived from waste automobile tyres through vacuum pyrolysis. The combustion parameters such as heat release rate, cylinder peak pressure, and maximum rate of pressure rise also analysed. Results showed that the brake thermal efficiency of the engine fueled with TPO-DF blends increased with an increase in blend concentration and reduction of DF concentration. NO x , HC, CO, and smoke emissions were found to be higher at higher loads due to the high aromatic content and longer ignition delay. The cylinder peak pressure increased from 71 bars to 74 bars. The ignition delays were longer than with DF. It is concluded that it is possible to use tyre pyrolysis oil in diesel engines as an alternate fuel in the future.
Experimental Investigations on Diesel Engine Fueled with Tyre Pyrolysis Oil and Diesel Blends
The prices of conventional fuels are increasing day by day due to technological constraints, gap in the demand and supply and scarcity of conventional fuels. Environmental pollution is also increasing by the usage of crude oils and hence there is a need for exploration of alternative fuel sources for automobile applications. Bio-diesel is a renewable fuel which is derived chemically by reacting with the sources of bio diesel. In the present investigation the alternative fuel used is the tyre pyrolysis oil, which was obtained by the pyrolysis of the waste automobile tyres. In the initial stage the tests are conducted on the computerized 4-stroke single cylinder water cooled DI-CI diesel engine by using diesel and base line data is generated. Further in the second stage experimental investigations are carried out on the same engine with same operating parameters by using the tyre pyrolysis oil blended with diesel in different proportions such as T10, T20 and T30 to find out the performance parameters and emissions. Among the three blends T20 has shown better performance in terms of engine performance and emission control, there by T20 is taken as the optimum blend. Finally the performance and emission parameters obtained by the above test are compared with the base line data obtained earlier by using diesel.
Due to the higher energy demand, constrict emission norms and shortage in oil resources led the researchers to find alternative fuels for IC engines. Many alternatives fuels such as Alcohols, Biodiesel, LPG, CNG, etc. already have been developed and commercialized. In this context, the pyrolysis oil obtained from the waste tyre is receiving renewed interest. The properties of the Tyre pyrolysis oil was compared with the petroleum products and found that it can also be used as a fuel for diesel engine. So, tyre pyrolysis oil can be used as an alternate fuel in a diesel engine. The present paper represents the literature review for enhancing the performance and emission of the compression ignition engine for the blend of pyrolysis oil of tyre and diesel fuel.
Optimization of Diesel Engine for Tyre Pyrolysis Oil & Diesel Blend
Reduction of biological fuel resources and stringent environmental laws have forced researchers to develop methods to sustainingly manage resources. The focus has been shifting towards energy recovery from waste materials which can solve the problems. One of the biggest wastes in the automobile sector is automobile tires. These have an unfavorable impact on the atmosphere if they are not disposed properly. Further, tires are a source of energy so it's not suitable disposal means wastage of energy. Some methods have been developed to extract energy from waste tires. One of them is pyrolysis of tires which produces Tyre Pyrolysis Oil (TPO) by thermal decomposition of tires. The properties of TPO with diesel were analyzed and compared with diesel and found that it is also used as a fuel in diesel engines. Tests are carried out on a diesel engine running with dissimilar blends of TPO 15% on a volume basis. The value of the Taguchi identifies that compression ratio 18, injection pressure 160 bar and engine load 9 kg are optimum parameters for lowest specific fuel consumption. Engine performance is mostly influenced by engine load and is least influenced by pressure injection.
