In the study, the dynamic analysis of the engine piston assembly was compared with the
experimental measurements and the stable working speed was tried to be determined. The
theoretical model has been developed in addition to experimental results. The relationship
between the forces and torques applied in the crank mechanism such as gas force, inertial force
are properly addressed. In the stationary conditions, it should be observed engine life and
vibration beside the fuel consumption for efficiency of single cylinder engines, especially.
In the result of analysis, it was seen that the torque value is fall though the vibration is high at
low speeds. In high speeds, it was seen that the torque value is much while the vibration is low.
This situation is interpreted that specific engine should not be operated low speeds about not
vibration. According to perform analysis, it can be said that the band between 1600 and 2000
rpm seems convenient for ideal engine operation
