| Abstract: | In the paper established is a multi-body dynamic model of the valve train of the internal combustion engine, with which a series of dynamic simulation and analyses is carried out,the reliability of which is tested and which may be used to ex- actly describe the actual working conditions of the valve train of the engine. The results of the analyses may show the displace- ment of the valve train, the velocity and acceleration time curves and the loading-time process of the main parts of the valve train under the action of applied forces, such as the tappet. The study of the movement law and dynamic characteristics of the whole valve train provides a reliable basis for the following optimization of the valve system and developing the valve train of the en- gine on our own. |
