Internal combustion engines in now a days is the best available reliable source of power for all domestic, large scale industrial and transportation applications. The major issue arises at the efficiency of these engines. Every attempt made to improve these engines tends to attain the maximum efficiency. The performances of the diesel engines are enhanced by proper design of inlet manifold, exh...

Abstract One of the characteristic features piston engines are vibrations caused by pistons moving in cylinders. During engine design process, it is necessary to determine level vibration that can occur engine. This especially important for aircraft engines. Due minimization weight aircraft, limit factors may cause damage structure. these vibration, which resonance and, consequently, a dangerou...
