Abstract: Now days, there are many sources of renewable energy. Bio diesel is just one source, but a very important one. Currently Jatropha biodiesel (JBD) is receiving attentions as an alternative fuel for diesel engine. Present work is focused on analyzing experimentally the performance and emission characteristics of Jatropha oil biodiesel and addition of HHO gas along with Jatropha oil biodiesel in a single cylinder compression ignition engine. Biodiesel is extracted by transesterification of non-edible crude jatropha oil using ethanol and KOH as a catalyst. The biodiesel is blended with diesel. The blends used are J15 and J.HHO gas is produced from the process of electrolysis by using KOH as an electrolytic solution. The produced gas is made to passes through the bubbler are sent to the intake manifold of the intake air. The performance and emission characteristics are noted down and compared. It was observed that there was a rise in brake thermal efficiency and lesser specific fuel consumption, Reduced Oxygen content in exhaust gases, lesser HC and CO emission and there was a rise in NOX emission when HHO is supplemented with biodiesel. Performance characteristics obtained on supplementing jatropha biodiesel fuel with HHO are obtained from the experiments.

Abstract: A single cylinder small engines have low compression ratio (CR), and they run with slightly rich mixture, their power are low and emission values are high. In this study, was used to increase performance and decrease emissions of a single-cylinder engine. Initially, the engine was tested with gasoline and Dibutyl Ether at full load and various speeds. This method is used for increasing the fuel efficiency of a vehicle by adding different percentage of Dibutyl Ether to the petrol. Due to the continuously increases in the cost of fossil fuels, demands for clean energy have also been increasing. Therefore, alternative fuels sources are sought to have alternate source for petrol without altering the existing engine or slight changes in the engine at low cost. In this paper the engines is tested without blending and with blending of Dibutyl Ether in various proportions with petrol and the corresponding readings were recorded.

Abstract: Investigational sample of thermoelectric refrigeration system working on solar photo voltaic cells generated DC energy. The urbanized tentative example having a refrigeration space of 1.36liter capacity is refrigerated by using heat sink fan assembly to increase heat dissipation rate from hot side of cooling module. The experimental result shows a temperature reduction without any heat load and with 30.4°C water kept inside refrigeration space in 30 minute with respect to 37.2°C ambient temperature. Also the COP of refrigeration cabinet has been calculated. The developed thermoelectric refrigeration organization is having possible submission of storage and transportation of life saving drugs and biological equipment at remote areas of our nation where grid authority is engaged. The project support heating and cooling. The project has different applications similar to, military, medical and pharmaceutical equipment. Thus it proves to be very helpful.

Abstract:The solar collector performance can be enhanced with help of Nanofluids. The Nano fluid has high conductivity property. So, it can be able to absorb maximum possible concentrated incident solar radiation and also change the heat transfer characteristics of the base fluid. The experimental investigation was carried out to study the performance of a Parabolic Trough Collector using the deionized water and water-based Al2O3 nanofluids as the working fluid. In this experiment, 0.1% volume and 0.3% volume of Al2O3 nanoparticles concentration have been taken for analysis. The result showed that the better performance of a Parabolic Trough Collector is achieved while using 0.3% volume concentration of Al2O3 nanofluid and it is also compared with the conventional fluid under the outdoor condition.
