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 was developed in addition to the experimental results. The relationships between the forces and torques applied in the crank mechanism, such as gas force and inertial force, are properly addressed. In the stationary conditions, the engine life and vibration should be observed besides the fuel consumption for the efficiency of single-cylinder engines.

The result of the analysis shows that the torque value that is low though the vibration is high at low speeds. In high speeds, it was seen that the torque value is more when the vibration is low. This is interpreted that the specific engine should not be operated at low speeds about not vibration. According to the performance analysis, the band between 1600 and 2000 rpm seems convenient for ideal engine operation.

运行中的单缸柴油机活塞总成的实验动力学分析

在研究中,发动机活塞组件的动态分析与实验测量进行了比较,并试图确定稳定的工作速度。除了实验结果之外,还开发了理论模型。曲柄机构中施加的力和扭矩之间的关系,例如气体力和惯性力,得到了适当的解决。在静止状态下,为了提高单缸发动机的效率,除了燃料消耗外,还应观察发动机的寿命和振动。

分析结果表明,低速时虽然振动大但扭矩值低。在高速下,可以看出,当振动低时扭矩值更大。这被解释为特定发动机不应以低速运行,而不是振动。根据性能分析,1600 到 2000 rpm 之间的范围似乎很适合理想的发动机运行。
