The influence of drive parameters and technical condition on the vibroactivity of devices with single-cylinder internal combustion engines

The study presents the important issue of the noise emission, generated bysingle-cylinder internal combustion engine constructions. This type of engine is used indrives of different types of machines and devices, including transport machines. In thestudy, the measurements and results analysis were conducted, which aim was to estimatethe influence of the engine capacity, their power and the change of the technicalcondition on the generated noise. The researches of exemplary lawnmowers, equipped inthis type of drive, showed the reduction of the sound level, together with the increase ofthe engines capacity and power decrease, and the increase of the noise (a few decibels)caused by the change of the technical condition during the operation.
