Original Abstract

The paper is focused on designing, different variants comparing, and selecting of the most suitable design of crankshafts for two-stroke CI engine with contra-running pistons and through-flow scavenging. The crankshafts variants are based on the analysis performed with the powertrain balance and include various combinations of requirements on strength, weight as well as balance. Applying FEM and MBS procedures, all variants go through dynamic simulations for the whole spectrum of operation speed, and the suitable design is selected with reference to the criterion of minimizing torsional vibrations, fatigue life of individual engine parts, and the load of main bearings.
