Design and Analysis of Hybrid Turbocharger

Abstract

Abstract: Internal Combustion engines have the capacity to exploit its increase in performance. Part ofwhich can be boosted by the technical solution that is turbocharging. To optimize the turbocharging to react as fast as possible and to adjust the volumetric flow of exhaust gases in the turbine, different alterations to turbochargers are done. To optimally support downsizing of Internal Combustion engines, these alterations are necessary. In a VGT there are vanes on the compressor that change the A/R of the turbo as needed. VGTs show a great improvement over conventional single turbocharger. Sequential turbocharger has an edge over VGT, but they are much more complicated. A 2.2L sequential turbocharged engine is same in performance as a 2.7L VGT engine. Exhaust gas turbocharging is a major technology for reducing fuel consumption and emissions in internal combustion engines, improving engine performance while cutting CO2 emissions. There are also electric turbochargers that almost totally eliminate turbo lag by using a motor to spin the compressor and use a generator on the turbine to recover exhaust gas energy. This application reduces fuel usage by up to 5% for driving cycles. EATC reduced the time it took to reach the optimum boost level during a load increase by up to 30%. Turbocharging is a major technology for reducing fuel consumption and emissions in internal combustion engines, improving engine performance while cutting CO2 emissions. Hybrid Turbocharging application leads to remarkable improvement at lowend torques, better engine performance and increased overall engine efficiency which paves way for downsizing of Internal Combustion engines.
