Experiments were conducted to study the performance, emission and combustion characteristics of a DI diesel engine using sea lemon oil-based fuels. In the present work, sea lemon oil and sea lemon oil methyl ester are tested as diesel fuels in diesel engine in neat form. The reduction in NOx emission and an increase in smoke, hydrocarbon and CO emissions were observed for Neat sea lemon oil compared to those of standard diesel. From the combustion analysis it was found that ignition delay was slightly more for both the fuels tested compared to that of standard diesel. The combustion characteristics of sea lemon oil and its methyl ester closely followed those of standard diesel.Keywords

We present the various ways by which hydrogen gas is generated and its methods of storing. The future hydrogen economy will feature hydrogen as an energy carrier in a reliable and sustainable energy supply system. Building an infrastructure that allows for easy and cost-effective transportation and delivery of hydrogen energy is a critical step.Keywords

Rockets with combustion chamber would reach 3500K to 3700K. For efficiency reasons and safe design of ejectors, after-cooler is interposed between the diffuser and ejector. This process is also operated at fairly high pressure 10 to 200 bar. Due to high temperature and pressure, thermal shocks generated are prevented by spraying water particles uniformly inside the gas cooler. In this paper, the significance of water spray characteristics is studied thoroughly. The water droplet evaporated into a flow of exhaust gases with a droplet size of 15 microns diameter increases the total surface area and is about 400 m2. The spray cooler length is suggested as 7-9 m to reduce the component of unevaporated water for optimum mass flow rate of primary fluid. Water injection velocity and pressure are varied as using number of nozzles. The injection pressure is reduced 10 times (2.0 - 2.5 bar) by increasing the number of nozzles (about 2000) in quadruple.Keywords

Due to the increasing demand for fossil fuels and environmental threat, a number of renewable sources of energy have been studied worldwide. An attempt is made to assess the suitability of vegetable oil for diesel engine operation, without any modifications in its existing construction. One of the important factors which influence the performance and emission of diesel engine is fuel injection pressure. In the present investigation a vegetable oil, Sea lemon oil has been investigated in a constant speed, DI diesel engine with varied fuel injection pressures (170, 190,210 and 230 bar). The main objective of this study is to investigate the effect of injection pressures on performance and emissions characteristics of the engine. The injection pressure was changed by adjusting the fuel injector spring tension. The performance and emission characteristics were presented graphically and concluded that increase in injector opening pressure increases the brake thermal efficiency and reduces unburned hydrocarbon and smoke emissions significantly.Keywords
