Abstract

Turbocharger is one of the approaches that utilize the exhaust gas of an automobile to drive the compression device. The purpose of turbocharging is to increase the intake pressure and the amount of air into the combustion chamber to improve the efficiency of the engine. One of the main problems with turbochargers is that they do not provide an immediate power boost when the accelerator pad is pressed, and the car would accelerate forward suddenly when the turbocharger gets moving. This study investigated how the design of a turbocharger’s turbine-compressor assembly affects the efficiency of a turbocharger and improved the design of the turbinecompressor assembly in term of transient response. Computational Fluid Dynamics (CFD) program is used to simulate fluid flow of the design. And rapid prototype machine is used to make a prototype of the turbine-compressor assembly. The major contribution of this project is the design concept that can be implemented to other turbocharger to reduce the effect of turbo-lag and improve the transient response of a turbocharger.
