Variable Compression Ratio Engines 2009-36-0245

The main focus of this work is to study variable compression ratio engines. The study begins with an analyze of the benefits of a variable compression ratio for Otto Cycle engines including mechanisms that already exist, the usual constructive solutions and the project criteria adopted in the area.
The kinematic and dynamic model of SVC Saab mechanism, using Newton-Euler equations, is developed. Also, the cylinder pressure curve is important to be determined. The pressure curve and the cylinder volume function will be evaluated analytically considering the variation of the compression ratio.
Furthermore, in order to know the influence of the design parameters in kinematic and dynamic, some sensitivity analysis of the engine mechanism will be performed. Finally, a computational implementation of the engine mechanisms analyzed will be done in Matlab language. This implementation includes the crank mechanisms and its kinematic and dynamic analyzes.
