Abstract

Gasoline engine downsizing, associated with turbocharging, has proved to be one of the most effective ways to reduce specific fuel consumption of the internal combustion engine. This tendency introduces a number of technical challenges, such as reduced steady-state low speed torque, delay in transient response caused by the turbocharger, combustion limitations due to propensity to knock. Advanced boosting systems can succeed in overcoming these issues; of particular interest is the solution featuring a second, electrically-driven, compressor in series with the turbocharger compressor. The engine considered in this work is a four-cylinder inline, turbocharged and electrically supercharged engine by FCA. In this work a 1D simulation of the mentioned engine is performed with and without the use of the electric supercharger in order to analyze its effect on steady-state and transient performance. The exploited software is GT-Power Version 7.4, by Gamma Technologies.
