Cooking Oil

Exploitation of the natural reserves of petroleum products has put a tremendous onus on the automotive industry. Increasing pollution levels and the depletion of the petroleum reserves have lead to the search for alternate fuel sources for internal combustion engines. Usage of vegetable oils poses some challenges like poor spray penetration, valve sticking and clogging of injector nozzles. Most of these problems may be solved by partial substitution of diesel with vegetable oil. In this work, the performance and emission characteristics of a direct injection diesel engine fueled by waste cooking oil-diesel emulsion with different water contents are evaluated. The use of waste cooking oil-diesel emulsion lowers the peak temperature, which reduces the formation of NOx. Moreover the phenomenon of micro explosion that results during the combustion of an emulsified fuel finely atomizes the fuel droplets and thus enhances combustion. Experiments show that CO concentration is reduced as the water content is increased and it is seen that 20% water content gives optimum results. Also, there is a significant reduction in NOx emissions.

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.

Alternative fuel sources are needed to be developed to meet the escalating demand for fossil fuels. Also from an environmental point of view, these most modern resources of fuels must be environment-friendly. The rapidly increasing consumption of fossil fuel and petroleum products has been a matter of concern for many countries which imports more crude oil. So, there is necessary for the development of new energy sources. The biomass, edible oil, inedible oils from plants and fish fat oil are imperatives and seen to be a potential substitute for diesel fuel. Acid and Base catalyzed transesterification is the most acceptable process for biodiesel production. In this project, an attempt towards finding the effect of alternate fuels as a substitute over diesel and reduce its consumption to lessen the environmental effects. Biodiesel has been extensively used in diesel engines as a partial substitute in the past few decades. The present investigation is carried out with blending up fish oil biodiesel with diesel in varying proportions to test out the emission and performance characteristics of direct injection single cylinder, four strokes, and air-cooled diesel engine. The fish oil biodiesel was produced by the transesterification process and obtained fish oil biodiesel blended with diesel fuel with various propagations of B20, B50, B75 & B100. These blended fuels were further investigated in a diesel engine with variable speeds such as 1000rpm, 1250rpm, 1500rpm, 1720rpm, 2000rpm 2250rpm & 2500rpm. In this comparative study, the effects of fish oil biodiesel fuel blends are compared and evaluated with pure diesel.

Due to the ever-reducing conventional petroleum resources, considerable research on renewable energy sources such as biodiesel as a possible “greener” substitute fuel for internal combustion engines is needed. This study aims to compare the engine performance and emission results of various blends of pure diesel and a multi-feedstock (MFS) biodiesel when used in a naturally aspirated air-cooled, single-cylinder direct injection diesel engine. The engine was coupled to a dynamometer for torque measurement and output data transmitted to a PC for post-processing and displayed using customized programs in the computer. Engine combustion products — Nitrogen Oxide emissions (NOx), Hydrocarbons (HCs), Carbon monoxide (CO) and Carbon dioxide (CO2) — were measured and are presented alongside performance properties including brake-specific fuel consumption (BSFC), engine efficiency, torque and power. The experimental results show that, relative to diesel, biodiesel had approximately 3–24% decrease in torque, 4–11% decrease in power, 11–32% increase in BSFC and 8–29% general reduction in engine efficiency. However, biodiesel reduced the emissions of CO (1.5–6%), CO2 (13–34%) and unburned HCs (3–25%), while NOx emissions were increased significantly (12–48%). These results indicate that smaller percentages of biodiesel (20% or less) could be blended with pure diesel and used in a diesel engine, without any engine modifications, as an alternative and environmentally friendly fuel and without significantly compromising engine performance.

Material Choice

The piston material choice is a major factor in the design stages of internal combustion engines for its importance to improving the durability and the operation reliability during the piston life cycle. Indeed, even as many researches have been conducted for a long time to improve the piston performances in the diesel engine, considerable numbers of piston damages still significantly occur. This research work is an assessment by the finite element method (FEM) of a set of piston materials for the purpose of being used in a direct injection diesel engine. The main objective is to predict stresses concentrations and the clearance between the piston and the cylinder (to avoid metal-metal adhesion) from thermomechanical solicitations. The stresses and deformations are evaluated in a 3D piston model by using ABAQUS software. A first assessment step is performed in heat convection/conduction modes to determine the temperature distribution. Then, this last one is coupled to the pressure field resulting from the gas combustion in order to compute stresses and the magnitude displacement. The obtained results show that the austenitic steel AS12UNG with fibre-reinforced possess low thermomechanical stress values compared to other material types. This material allows a minimum failure risk and therefore contributes to the enhancement of the piston design.

The main objective of this study was assessment of the performance, emissions and combustion characteristics of a diesel engine using RME–1-butanol blends. In assessing the combustion process, great importance was placed on evaluating the stability of this process. Not only were the typical COVIMEP indicators assessed, but also the non-burnability of the characteristic combustion stages: ignition delay, time of 50% heat release and the end of combustion. The evaluation of the combustion process based on the analysis of heat release. The tests carried out on a 1-cylinder diesel engine operating at a constant load. Research and evaluation of the combustion process of a mixture of RME and 1-butanol carried out for the entire range of shares of both fuels up to 90% of 1-butanol energetic fraction. The participation of butanol in combustion process with RME increased the in-cylinder peak pressure and the heat release rate. With the increase in the share of butanol there was noted a decrease in specific energy consumption and an increase in engine efficiency. The share of butanol improved the combustion stability. There was also an increase in NOx emissions and decrease in CO and soot emissions. The engine can be power by blend up to 80% energy share of butanol.

Performance And Emission

This paper presents a comparative analysis of the diesel engine performance and emission characteristics, when operating on diesel fuel and various diesel-biodiesel (B10, B20, B40, B60) blends, at various loads and engine speeds. The experimental tests were performed on a four-stroke, four-cylinder, direct injection, naturally aspirated, 60 kW diesel engine D-243. The in-cylinder pressure data was analysed to determine the ignition delay, the Heat Release Rate (HRR), maximum in-cylinder pressure and maximum pressure gradients. The influence of diesel-biodiesel blends on the Brake Specific Fuel Consumption (bsfc) and exhaust emissions was also investigated. The bench test results showed that when the engine running on blends B60 at full engine load and rated speed, the autoignition delay was 13.5% longer, in comparison with mineral diesel. Maximum cylinder pressure decreased about 1–2% when the amount of Rapeseed Methyl Ester (RME) expanded in the diesel fuel when operating at full load and 1400 min–1 speed. At rated mode, the minimum bsfc increased, when operating on biofuel blends compared to mineral diesel. The maximum brake thermal efficiency sustained at the levels from 0.3% to 6.5% lower in comparison with mineral diesel operating at full (100%) load. When the engine was running at maximum torque mode using diesel – RME fuel blends B10, B20, B40 and B60 the total emissions of nitrogen oxides decreased. At full and moderate load, the emission of carbon monoxide significantly raised as the amount of RME in fuel increased.

In the present work, the combustion, performance and emission characteristics of sunflower oil, sunflower methyl ester and its blends were studied and compared with diesel by employing them as fuel in a single cylinder, direct injection, 4.4 KW, air cooled diesel engine. Emission measurements were carried out using five-gas exhaust gas analyzer and smoke meter. The performance characteristics of Sunflower oil, Sunflower methyl ester and its blends were comparable with those of diesel. The components of exhaust such as HC, CO, NOx and soot concentration of the fuels were measured and presented as a function of load and it was observed that the blends had similar performance and emission characteristics as those of diesel. NOx emissions of sunflower oil methyl ester were slightly higher than that of diesel but that of sunflower oil was slightly lower than that of diesel. With respect to the combustion characteristics it was found that the biofuels have lower ignition delay than diesel. The heat release rate was very high for diesel than for the biofuel.
