The noise generated by the four-stroke S320 Andoria internal combustion engine is a complex field of study because the total sound pressure is the sum of the sound pressures produced by each engine component. The noise level and sound frequency of diesel engines used in agricultural machinery are highly dependent on fuel combustion. The standard diesel fuel conforming to EN 115 was used in the tests. Sound pressure was measured with the Bruel & Kjear equipment. Investigations show the dynamics of the dynamic parameters of the four-stroke engine, which must be evaluated when operating agricultural machinery. Experimental research of power influence on sound pressure of four-stroke diesel engine was performed. The dependence of the sound pressure level on the variation of the motor power was determined. Studies have shown that as the engine power increases from 2.63 to 9.48 kW, the sound pressure standard deviation increases by about 0.041 Pa.
