Taking the YN4100QB diesel engines as the research object, acoustic power of the radiation noise from the surface of the engine has been tested and calculated, which utilizes the measuring method of superficial acoustic pressure levels based on the simulation system of atmospheric pressure. The engine's combustion noise, mechanical noise and inlet noise have also been successfully separated with the...
