Abstract
The „downsizing” phenomenon has grown and has led to the technological and efficient use of the supercharger systems. Despite this, conventional turbocharging systems have a transitional response due to the exchange of power with the engine and affect the elasticity of the engine. An electrically actuated turbocharging system can eliminate this shortfall, transient operation, without loss of interference, as the response is instant to the electric drive. A power recovery system can be added to increase overall efficiency. The study provides an overview of the influence of the compression ratio of a compression ignition engine to which an electric power-driven axial compressor has been attached. The results showed that the implementation of an electric compressor and a high compression ratio contribute to increasing yields and reducing losses in the operating cycle.
