The clear objective of exhaust gas turbocharging is the increase in power density of reciprocating piston internal combustion engines by means of precompressing the work medium, i.e., air. It utilizes the exhaust gas energy which otherwise — due to the geometrically given expansion ratio of the crank mechanism — would be lost at the end of the high-pressure cycle. Simultaneously, the boundary conditions for combustion and the high-pressure cycle can be improved so that their control and emission level can be optimized.
