In recent times, due to possible depletion of fossil fuels, it is necessary to design fuel-efficient engines with better performance characteristics. This will not only save energy but will also facilitate its sustainability. From the era since engines are developed, vibrations is one of the most serious problem that needed attention. Configuration of an engine plays a very crucial role in stability and balancing of the parts. Considering this aspect, this work focuses on designing of a new horizontal K-type configuration, which is better balanced and stable than the existing configurations. Center of gravity influences stability and power-weight ratio is one of the key parameter when it comes to performance of the engine. The higher the power-weight ratio, the better is the performance of the engine. Reducing the inertia of rotating and reciprocating components has a positive impact on fuel efficiency.
Thus balancing of existing configurations is studied and its limitations are addressed in the proposed configuration. MATLAB code is used to replicate the physics of the new proposed configuration and finite element analysis is performed using ABAQUS software. The various components are constrained via joints and the resultant effect of the motion is studied in multibody dynamics (MBD). Dynamic analysis is important so as to understand how an individual component behaves with respect to its neighboring components and also with the environment. MBD is performed using ANSYS and MSC ADAMS software. Subsequently, a prototype is 3D printed for analyzing the motion of the rotating and reciprocating parts.
