Contributions to applied research OF kinematic-phenomenological aspects of PISTON-rings for compression ignited engine used in agriculture and automotive industry
The present scientific paper synthesizes an applied work on the engineering task of piston-ring displacement modelling and simulation in the case of an internal combustion engine for agricultural application. Piston-rings configuration and displacement, as well as their particular role in the whole assembly, materials, dimensions and lubrication process, in various working cases, are quite significant in influencing the engine’s performance and economy (oil consumption and pollution). In this paper are highlighted the piston-ring displacement modelling and their critical efforts analyse for an agricultural engine, defined on the bases Lombardini tractor engine (510 ccm). The opportunity and importance of modelling the piston-rings movement at different levels and cases in the operational cycle lay on the possibility of highlighting their stresses and predict work expectancy.
