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.
Emission Analysis 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 injection pressure.
Many alternate fuels like Alcohols, Biodiesel, Methanol, Ethanol, LPG, CNG etc have been already commercialized in the transport sector. In this context, pyrolysis of solid waste is currently receiving renewed interest. This research describe a comparison of the use of pyrolysis oils which are the tire pyrolysis oil, plastic pyrolysis oil and diesel oil in the assessment of engine performance, and feasibility analysis. Pyrolysis oils from waste tire and waste plastic are studied to apply with one cylinder multipurpose agriculture diesel engine. It is found that without engine modification, the tire pyrolysis offers better engine performance whereas the heating value of the plastic pyrolysis oil is higher. The plastic pyrolysis oil could improve performance by modifying engine. The economic analysis shows that the pyrolysis oil is able to replace diesel in terms of engine performance and energy output if the price of pyrolysis oil is not greater than 85% of diesel oil. Tests have been carried out to evaluate the performance analysis of a single cylinder direct injection diesel engine fueled with 5%,15%, 25%, 50%,75%and 85% of tyre pyrolysis oil (TPO) blended with Diesel fuel (DF). The TPO was derived from waste automobile tyre through vacuum pyrolysis. Best suitable blend was found and pyrolysis oil was added in concentration of 50%,75%, with 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.

Environment pollution is a great hazard to our ecosystem which is greatly affected by the emissions from internal combustion engines. Also with the degradation of fuel it is high time that we find alternative source for generation of power from internal combustion engines. The modern thrust of the research is to obtain three blends of diesel with tyre pyrolysis oil in 10:90, 20:80and 30:70 ratios and analyse the engine emissions like Carbon-mono-oxide (CO) and HydroCarbons(HC).In doing so, it was found that CO emission is 0.16%. 0.15%, 0.15% and 0.16% by volume for the blends mentioned above and for diesel respectively.
Optimisation of performance and emission parameters of diesel engine using tyre pyrolysis oil
Australian Journal of Mechanical Engineering, 2020
In this paper the effect of incremental rise of tyre pyrolysis oil in the blend is analyzed to explore the performance and emission parameters of a single cylinder VCR diesel engine. During experimentation proportion of TPO were 10, 25, 35, 50, 60, 75 and 90 % with diesel fuel. Tests were conducted using four different loading conditions. The experiments were performed using an analytical tool known as Design of Experiments on the basis of Response Surface Methodology. The conclusive models of the RSM prepared to predict the response criterion such as BSFC, BTE, CO, nitrogen oxides, smoke and Mechanical efficiency. The results depicted that with rise in the load, BSFC decrease while it increases with rise in TPO proportion and found lower at 50% TPO and increases again above 50% TPO. BTE increased with increase in the load and found to be highest at higher TPO. For all blends, an increase in Nitrogen oxides found with increase in load and TPO proportion. Parameter optimization executed using the desirability approach method of the RSM for improved conduct and reduced emissions. A load of 4.57 kg (61.7567%) and 40.94% TPO in the blend are suggested as the optimal criterion for the test engine.

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 effect of operating parameters on performance and emission characteristics of a single cylinder diesel engine fueled by TPO10, TPO15, and TPO20 at a crank angle 28 0 before TDC (Top Dead Centre) and injection pressure of 190 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 4.5 to 5.5%. CO emissions are slightly higher but within permissible limit of euro IV emission standards. HC emissions are higher by about 45 to 65% at partial load whereas smoke opacity is lower by about 10% to 25% as compared to diesel fuel.

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 fuelled by TPO10, TPO15, and TPO20 keeping the blend quality by controlling density and viscosity of tyre pyrolysis oil within permissible limit of euro IV diesel requirement to study its replace ability. The investigation involves three parameters such as blend proportion, injection timing and injection pressure, a simultaneous optimization method called Taguchi was used in this work. This method requires fewer numbers of trials for fixing optimum levels. As per this method nine experiments were required to be conducted and the results were used for optimization. This is the primary advantage as well as disadvantage of this method. In order to eliminate this difficulty and improve the quality of the research work, twenty-seven experiments were conducted in this work and the results were used for optimization. In addition, an ANOVA was also performed for the parameters to evaluate its percentage contribution over the desired output. Using the optimum levels, a full range experiment was conducted to compare its performance and emission behaviour with standard diesel operation.
