Combined Effect Of Inlet Manifold Swirl And Piston Head Configuration In A Constant Speed Four Stoke Diesel Engine

Abstract

The internal combustion engine manifold has a subsystem that supplies the fresh A/F mixture to the engine cylinders where the fuel is combusted. For efficient combustion of charge, the walls of the intake manifold must be smooth / polished to minimize any side resistance. To redesign the inlet port of a small internal combustion engine, to increase the production of turbulence by a swirl. A good swirl promotes more rapid combustion and improves efficiency. The CI engine has a piston shaped flat on the crown and a concave combustion chamber, with this geometry we are driving the engine. But here the A/F ratio mixture cannot mix properly. To avoid this we make piston geometry changes. The main objective of this project is that three new technologies have been adopted here. The first stage is varying the diameter of the convergence - the divergent nozzle. The second stage is the change on the piston head and the last stage is replacing the inlet and exhaust valve with pitch 0.5. Mm to 2 mm and the cut thread depth is 4 mm and three threads per inch. All of these techniques aim to investigate performance techniques to increase air flow to achieve improved engine performance and emissions in direct injection (DI) single cylinder diesel engines. Compared with traditional engine.
