Our main aim is to modify nozzle designs of a fuel injector in railway engine to generate more power as output by which rail engine can carry more load. There are many ways to increase the power generated from engine, by considering one of the best one among them through which power generated from the railway engine increases. The purpose of this is to calculate the design of fuel injectors plunger, barrel and nozzle for 450HP, V-16 diesel engine. In V-16 engine 16 similar fuel injectors supply the fuel as per the cam rotation, so we modify one of them and apply to all fuel injectors. In the case of high-pressure diesel fuel-injection the flow conditions inside the fuel injection holes have an important influence on the development of the spray. Therefore, the design of fuel injector nozzle is very important for engine performance. The injection pressure of this engine is 2700psi and compression ratio is 17. The large pressure differences across the fuel injector nozzle give higher jet velocity at nozzle exit. Fuel injected pressure and cylinder pressure derivations are carried out to provide for fuel injector nozzle’s design. The simulated results show that the best design for a nozzle is by using smaller holes size where turbulent flow is well developed inside the nozzle and by modifying dimensions of plunger and barrel allows to hold more volume of fuel leads to increase horse power.

To provide the materials to exhaust pipe of a diesel locomotive. In order to reduce of damage to turbine, we decided to provide material. We are considering two layers of absorption with 12mm thickness each. It is to achieve lower amount of heat transfer. As the engine is connected to turbocharger using exhaust pipe, this hot steam can be impregnated on to turbine at exhaust housing of turbocharger. So that efficiency also increases. In this project, we practically prove that two layers using various materials results in fast decrease in temperature. Of all the obtained results it is identified that, through materials maximum of temperature is minimized which results in good performance and lifetime for turbocharger. By this the people will not be affected. We must also consider the environmental conditions. Under all circumstances our project is successful. There may be heavy rains, or snow but the system must be capable of working in any environmental condition. There are coolants used to reduce of temperature amount. A material acts as a shield to the source. It’s very light in weight

Keywords: CATIA, ANSYS, Nozzle , Exhaust pipe.
