The diploma thesis deals with the calculation of thermodynamic parameters of a turbocharged petrol engine with Miller cycle. A drive unit from Volkswagen, the EA211EVO model line, was chosen as the engine. The engine has a displacement of 1498 cm3 and engine power reaches 110kW at 5000 to 6000 RPM. In this work, a basic description of the thermodynamics of cycles of spark ignition engines is performed, then the problem of turbocharging and methods of its control are presented. The following are the created engine models in GTSuite environment in variants with WasteGate and Variable Turbine Geometry. Finally, operation optimizations with various valve timing changes are presented. The individual variants are the compared.
