This Diploma Thesis is aimed at exploring the potential of offset crankshaft mechanism for four cylinder inline petrol engine in terms of reducing the frictional losses of the piston group. Thesis deals with the influence of eccentricity on kinematics, dynamics and balance of the crank train. Furthermore, specific crankshaft balancing is elaborated and applied on 3D CAD model of the crankshaft. Calculation of fatigue safety factor using the advanced LSA method that takes into consideration the effect of forced torsional vibration and utilizes outputs from the FEA software (ANSYS APDL) is performed as well. Thesis also includes design of two options of rubber torsion damper mounted on the engine belt pulley and the follow-up choosing of the more advisable one.
