Internal combustion engine design is a complex operation in which a large quantity of variables must be considered. In industrial field, a new internal combustion engine project starts from the development of well-established solution and from the designer experience. The aim of this research is the development of a series of procedures to design and to verify all main engine components starting from a deep bibliographic research. Every engine component (crankshaft, piston, piston pin, connecting rod, engine block, engine head, bearings and valvetrain) has its own interface for the design and the check. First of all, a deep bibliographic analysis was performed in order to find the best design procedures and a series of geometrical and thermodynamic data for a generic internal combustion engine. All these data are used as calculation input data. A large number of input data are in common for all the components and they are implemented in an input interface while other information, such as components material or typical geometric dimension, are requested in the specific component interface.
