During operation of valvetrain elements in SI and CI engines an amount of vibrations is generated. Surface vibrations are transmitted as an acoustic waves to users of vehicles and can be measured using different technics, particularly with matrixes of sonometers. The most commonly it is measured the general level of sound generated in the engine and it is difficult to extract the pure form of vibrations caused by the operation of individual elements of valvetrain. To obtain valuable data of sound level generated by such individual element it should be used the special methodology. The most often it is used the experimental researches on the physical model of engine including only one section of valve train or individual components. During such researches, after introduction of extortion in the form of the valve train operation cycle with the constant camshaft speed, the answer of the model in the form of sound level measured in different places is obtained. The model of research stand using FEM can be used to obtain the transmittance of the mentioned physical model. The model of the selected research stand has been elaborated using FEM and presented in the paper. The obtained sound levels resulted from the modelled signal introduced in the selected sources of valvetrain model have been presented in the article.
