In today's society, researchers around the world are searching for ways to develop alternate forms of fuel. With the ever-rising fuel costs, developing alternate energy is a top priority. Biodiesel was developed to combat the high gas and oil prices. It is especially made for use in diesel cars and trucks. Biodiesel can be made from all natural foods that can produce oil. Oils such as vegetable, canola, peanut, rapeseed, palm, and olive oil can be used as bio diesel fuel. Virtually all oils that are used in the kitchens everyday can fuel automobiles. Biodiesel fuel is better for the environment because it burns cleaner and does not pollute the atmosphere. It is non-toxic and biodegradable, making it the perfect fuel. Many car manufacturers are realizing that the bio diesel automobile is becoming more popular, and are jumping on the bandwagon, by developing their own version of a biodiesel vehicle. They realize that the need for these vehicles will increase, and predict that they will be ready for the onslaught. Diesel engines have superior fuel efficiencies, and hence they are predominantly used in commercial transportation and agricultural machinery. Due to the shortage of diesel fuel and its increasing costs, a need for an alternate source of fuel for diesel engines is imminent. This paper investigates the suitability of biodiesels as such an alternative with particular reference to automobiles. It reviews techniques used to produce biodiesel and provides a comprehensive analysis of the benefits of using biodiesel over other fuels.

Fossil fuel consumption provides a negative impact on the human health and environment in parallel with the decreased availability of this valuable natural resource for the future generations to use as a source of chemical energy for all applications in energy, power, and propulsion. The diesel fuel consumption in the transport sector is higher than the gasoline in most developing countries for reasons of cost and economy. Biodiesel fuel offers a good replacement for diesel fuel in compression ignition (CI) diesel engines. Earlier investigations by the authors revealed that a blend of 70% amla seed oil biodiesel and 30% eucalyptus oil (AB70EU30) is the favorable alternative renewable fuel blend that can be used as a fuel in diesel engines. With any fuel, air/fuel mixing and mixture preparation impact efficiency, emissions, and performance in CI engines. Minor adjustments in engine parameters to improve air/fuel mixing and combustion are deployable approaches to achieve good performance with alternative fuel blends in CI engines. This paper provides the role of a minor modification to engine parameters (compression ratio, injection timing, and injection pressure) on improved performance using the above mixture of binary fuel blends (AB70EU30). The results showed that the use of AB70EU30 in modified engine resulted in higher brake thermal efficiency and lower brake specific fuel consumption compared to normal diesel for improved combustion that also resulted in very low tailpipe emissions.

The research is devoted to possibility of mineral diesel fuel with mixed biodiesel fuel partial replacement, which contains the vegetable oil as a biological component (such as: rapeseed, camelina, radish, mustard, colza, soybean, etc.). Constructive versions of bi-fuel supply system and mixers for diesel engines adaptation for their operation by biodiesel fuel are offered. The advantages of the developed bi-fuel systems and mixers are: universality in relation to different types of diesel engines; polyfuelness; availability of components; competitiveness; possibility of production in the plant conditions, no requirement of big capital investments, the small term of payback. The application of the offered system by the diesel-powered machinery provides the necessary percentage ratio of mixed fuel components depending on the load-speed mode without its essential constructive changes. The using of the mixed biodiesel fuel containing for example 50% of mineral fuel and 50% of camelina oil allows to save 50% of petroleum diesel fuel, to reduce smoke of the exaust gases by 17-20%, to reduce the content of carbon oxide by 35-40% in comparison with the work of the diesel engine on mineral diesel fuel, by insignificant decreasing of the effective power (no more than 6%) and by some increasing of specific fuel consumption of mixed fuel (to 14%).

Performance And Emission

Biodiesel has become more attractive recently, because of its environmental benefits and the fact that it is made from renewable resources. Over the past few decades, most of the countries depending on diesel engines for transportation. Some of its valuable advantages like highest thermal efficiency made it very popular. At the same time, the cost of diesel fuel is increasing, due to the depletion of fossil fuels. In this current scenario, we need an alternative fuel instead of diesel fuel. Many of the researchers have successfully placed several works on generating energy from different types of alternative sources including solar and some kind of conversion processes including renewable agricultural products into liquid fuel. One of the biggest challenges for developing countries in relation to energy consumption is to develop and implement technologies that help to improve efficiency of automobile engines, also to reduce the emissions of harmful gases and particulate matters. In order to avoid environmental impacts, emissions are reduced or eliminated by introducing renewable energy resources. The present research chronicles the production and testing of renewable biodiesel fuel derived from virgin coconut oil on a diesel engine, to analyses the engine performance and emission characteristics. In the first phase of work, production of biodiesel fuel from virgin coconut oil using transeterification process with two types of catalysts (homogenous and heterogeneous). The preliminary results shows that, with the addition of homogenous catalyst called Potassium Hydroxide (KOH) with methanol shows much higher activity than that of heterogeneous catalysts, and it shows more similar properties with diesel fuel. The results obtained from the chemical test and physicochemical properties of transesterified biodiesel fuel clearly proves the above-mentioned statement. The chemical tests such as GCMS and FT-IR clearly shows that the biodiesel fuel has sufficient amount of volatile components and functional groups. Then, physicochemical properties include, Fire point, Flashpoint, density, and viscosity were analyzed. Finally, Engine performance and Emission characteristics were analysed to confirm, whether this biodiesel fuel is suitable for diesel engines, without any engine modifications. It was found to be, the transesterified virgin coconut oil biodiesel has similar properties to that of the diesel fuel. From the physiochemical properties and engine performance clearly shows that, coconut oil biodiesel is suitable for diesel engine on blending, at a blending percentage level of 20% with conventional diesel fuel. Since the obtained transesterified biofuel can be used as an alternative fuel for diesel engines. The several journal reports and find outs from experimental investigation clearly depicts that the efficiency of the transesterified biofuel mainly depends upon the amount of catalyst adding and type of catalysts present in the biofuel, whether it is homogenous or heterogeneous catalyst is suitable with methanol. Finally, from the analysis made from biodiesel fuel. Coconut Oil Biodiesel fuel has less emission characteristics than that of the diesel fuels.

The main trends in modern diesel engines are the increase in fuel efficiency and operational reliability of engines, as well as their environmental safety, mainly related to stringent emission requirements for exhaust gases. The necessity of the world navy fleet in the non-existent amount of fuel is clarified, the forecast is made, which implies further increase of its consumption. The total capacity of marine engines in the world, and in the longterm perspective, until 2050, is determined. The number of emissions of harmful substances into the atmosphere by the ships of the world fleet is shown, international norms are regulated, which strictly regulate the number of these emissions, as well as the dynamics of the strengthening of norms for the present and for the future. Certain types of technological emissions and the composition of harmful substances in the exhaust gases of marine engines have been identified. They make up 0.1 - 1.0% of total emissions, are in gaseous state and include carbon monoxide oxides, NOx nitrogen, SOx sulfur, and hydrocarbon CrNy. Emissions of nitrogen oxides (NOx) with off-gas from marine diesel engines account for about 14% of global NOx emissions from the combustion of all types of fossil hydrocarbon fuels The analysis of methods of their purification is carried out. An analysis of recent publications has been carried out It is known that the quality of diesel fuel, its physical and chemical properties, affect the fuel economy and the content of harmful substances in the exhaust gases of the engine. The most common way to ensure the required properties of diesel fuel is the introduction of multifunctional impurities. The groups of impurities to diesel fuel are given. The influence of nano-metal impurity on Al2O3 fuel is analyzed. The analysis of diesel fuel with an admixture of aluminum oxide nanopowders (Al2O3) gamma-modification. It has been established that the additive to diesel fuel based on AL2O3 nanopowders is promising. It is expedient to carry out a complex of motor tests for introduction of an additive on the sea and river fleet
