Abstract The need of fuel is increasing constantly due to increase in population and industrialization all over the world. The increase in population and industrialization has put the increasing pressure on the use of non-renewable resources. The non-renewable resources like petrol, diesel, coal, natural gas, etc. are used for production of energy. The availability of fossil fuel is continuously decreasing due to increase in demand continuously, these reasons makes the researchers to find new renewable alternative fuel like biofuels. There are various vegetable plants like karanja, neem, soyabean, etc. are used for producting biodiesel only problem is the land availability, so the algae is now been used to produce biodiesel. It has been reported that use of biodiesel reduce the emission and increases the performance of engine. In this review we present an overview about algae use for biodiesel production, including their cultivation, harvesting and processing.

Abstract An experimental research is performed to determine the performance, combustion as well as emission qualities of a variable compression engine at constant speed using Copper Oxide nanoparticles as being fuel-borne additives in diesel–biodiesel blend. In this research, the effects of adding CuO2 nanoparticles to neochloris oleoabundans methyl ester-diesel blended (B20) fuel on compression-ignition engine had been experimentally investigated. The B20 with 25, 50, 75, and 100 ppm dosage of CuO2 nanoparticles were examined at various engine loads and constant engine speed. The fuel blends were labelled as B20, B20 + 25 ppm, B20 + 50 ppm, B20 + 75 ppm and B20 + 100 ppm. Moreover, even without the any engine alterations, the combustion properties of those fuel blend samples were investigated through the experimentally measured standards like viscosity, density, cloud point, calorific value and pour point while the engine combustion has also been examined through the factors like cylinder pressure, net heat release as well as rate of pressure rise. The experimental outcomes show that the use of biodiesel blend along with CuO2 nano particles in diesel fuelled engine has revealed better combustion than B20 fuel.

Abstract As the amount of heat that needs to be removed from four stroke spark ignition engine constantly increases, thermal engineers are faced with never-ending challenges not only to Provide innovative thermal designs but also to push the limits of the available technology Finite element analysis (FEA) can also be useful in determining performance, especially conductivity gradients. The heat transfer coefficient can be determined using advanced FEA codes which incorporate fluid mechanics. These simplified terms represent a combination of several factors, such as material conductivity, lateral fin conduction, boundary layer formation, and effective surface area; however, pin fin geometry cannot easily be modeled by using either method. Each pin must be individually discredited, increasing the modeling time substantially. A simulation program will be developed for predicting and optimizing thermal performance of hi-directional a) circular fin Fins b) axial fins C) circular fins with triangular profile Comparative thermal tests will be carried out using Aluminum two stroke S.I engine made with circular fin, axial fins, and circular fins with triangular profile with varying material properties of engine block. The results of the circular fin will be also compared with those axial fins, and circular fins with triangular profile using finite element analysis program developed on Ansys software. In addition to the temperature measurements, the Thermal stress distribution will be investigated.

Abstract The energy crisis is due to two reasons: one is the rapid growth of the global human population, and the other is the transformation of the residing human style. Traditional fuel is also a major component of adding pollutants to the environment. Changes in fuel consumption play a major role in increasing engine efficiency and reducing emissions. In the current research, fuel changes in the diesel engine were developed. The single-cylinder diesel engine was initially equipped with Botryococcus braunii algae oil methyl ester and its diesel blends with CuO2 nano additives B20, B20 + 25 ppm, B20 + 50 ppm, B20 + 75 ppm, B20 + 100 ppm at different loads at steady engine speed. From the experimental analysis, it has been shown that B20 is the more efficient fuel ratio than other blends. The results showed a significant reduction in CO, HC and smoke emissions. The current analysis shows that BBAME's biodiesel with CuO2 nano additives is best suited as an alternative diesel engine fuel.

ABSTRACT Microalgae biodiesel has been considered as a clean renewable fuel for diesel marine engines. This is due to its optimistic characterizations such as rapid growth rate, high productivity, and its ability to convert CO2 into fuel. In this study, the use of microalgae biodiesel, obtained from Botryococcus braunii, as an alternative fuel for diesel marine engines has been investigated. The diesel engine is verified experimentally using Ni-Doped ZnO nano additive blends with algae biodiesel and neat diesel fuel. The results showed that doped nano additive blends produce less emission compared to B20.

ABSTRACT In this present work, corn oil biodiesel with La2O3 was used as an additive with neat diesel fuel and blends were prepared. La2O3 nanoparticles are dispersed in the emulsions with different dosage levels of 50, 75, and 100 ppm. A single-cylinder, four-stroke CRDI diesel engine is made to run on different fuel concentrations to study the effect of emission characteristics of the fuel. The test engine was operated under constant engine speed (1500 rpm) and different engine load test conditions. According to the experimental results, fuel blends with biodiesel fuel emission increases CO2 and NOx and reduces the CO, HC, and smoke emissions compared with the B20 fuel.
