Biodiesel Fuels

The use of biological fuels based on vegetable oils and other similar raw materials in diesel engines in developed countries can reduce the cost of mineral diesel fuel and improve the environment. This issue is relevant for Ukraine as well, in connection with which the governing bodies pay great attention to it. The deepening of knowledge in the study of the peculiarities of the flow of operating cycles of diesel engines, their power and toxic characteristics at the same time contributes to the optimization of the use of these types of fuel. In this work, the main issues related to the use of vegetable oils, such as sunflower, rapeseed, corn oils and their ethyl esters, both in pure form and in a mixture with mineral diesel fuel, are considered as a biological component of fuel. Theoretical issues and experimental data related to the use of these fuels in diesel engines are considered. Experimental studies were carried out on diesel engines D21A and four-cylinder - Skoda - an analogue of the 1.9-liter Volkswagen engine with turbocharging. Economic and toxic characteristics were obtained by load and speed characteristics. There is an increase in the consumption of mixed fuel in comparison with mineral fuel, the toxic characteristics were better in some indicators, in some cases, for example, when operating at increased capacities, they worsened relative to those when operating on mineral fuel. The basic principles of the effective use of biofuels in transport diesel engines are formulated in terms of energy and toxic indicators, as well as the corrosive effect of blended biofuels on fuel equipment. Today, gas stations in Ukraine only sell alternative fuels for gasoline engines. These are mixtures in various proportions of gasoline and bioethanol with a content of the latter up to 35–40% by volume. The price of such fuel is lower than the price of gasoline. Biodiesel fuels are not commercially available, although they would also cost less than mineral diesel fuel. It is likely that the use of biodiesel fuels is restrained due to the need to adapt the diesel engine to these fuels and to monitor the state of the fuel equipment. However, these costs are small and can be easily compensated for by the difference in the price of mineral and biodiesel fuels. It can be assumed that, first of all, biodiesel will be introduced into agricultural machinery.

And Shifts

A significant portion of the automobile and industrial sector is mostly dependent on the running of diesel engines as it is efficient and shifts a large of the goods around the globe and power various equipment. Also, as the use of energy as diesel fuel is increasing enormously with the expansion of industrial growth, diversification, this led to the accelerating global emissions, global climatic change, health issues, and exhaustion of fuels. To succumb this, alternative fuel is needed to fight against the ill effects and as a replacement to diesel fuel. Thus, vegetable oils as alternative fuels are drawing more attention as they are renewable and do not address the problem of greenhouse gas. In the present work, the cottonseed oil was chosen as the favorite among the vegetable oils due to its advantages like less pollutant level, excessive availability, etc. The transesterification process was used to produce the cottonseed oil biodiesel. This research aims to investigate efficiency, emission characteristics by using smooth diesel, cottonseed oil, and mixtures with varying composition from 20 % to 80 % in 20 % steps to identify sustainable fuel as a substitute for existing fuel and to overcome fuel demand and enviro effects. This test was conducted on single-cylinder four-stroke water-cooled diesel engines. From the results, it was revealed that cottonseed oil and its blends have a significant influence on performance and emission characters. Keywords: water-cooled diesel engine, emission character, cottonseed oil, sustainable fuel.

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.

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.

Biofuels derived from renewable plant materials are considered promising alternative fuels to decrease emissions of ICEs. This study aimed to justify the possibility of using vegetable oils of different sources as a 10% additive in blended biofuel for diesel engines of agricultural machinery and commercial vehicles. Seven different vegetable oils were investigated. Experiments have been performed by fueling a diesel engine with blended biofuels of 90% petroleum diesel fuel and 10% vegetable oil. In the maximum power and maximum torque modes, the brake power drop was no more than 1.5%, and the brake-specific fuel consumption increase was less than 4.3%; NOx emissions were reduced by up to 8.3%, exhaust smoke—up to 37.5%, CO—up to 20.0%, and unburned HC—up to 27.9%. In the operating modes of the European 13-mode steady-state test cycle, the integral specific emissions of HC decreased by up to 30.0%, integral specific emissions of CO—up to 15.0%, and integral specific emissions of NOx—up to 16.0%. The results obtained show the feasibility and rationality of using the investigated vegetable oils as a 10% additive in blended biofuel for diesel engines of agricultural machinery and commercial vehicles.

Extensive research has been carried out with regard to the composition of the exhaust gases of Diesel engines in operation with biodiesel in relation to the operation with the conventional diesel fuel. Producing biodiesel from different raw materials and different technological biodiesel production processes can result in different individual physical and chemical characteristics of fuel. Generally, it can be said that the use of biodiesel (and mixtures) reduces the overall toxicity of the exhaust gases in relation to the operation of the engine with diesel fuel, and this is a significant environmental potential of biodiesel as a fuel for Diesel engines. However, there is a diversity of research results, due to different factors. The paper reviews and summarizes the relevant literature on the mentioned research that can contribute to the explanation of these effects. It also points to the need for a very careful selection of biodiesel for use as a Diesel engine fuel.
