Diesel Generator Tech

The noise of generator set is mainly comes from  engine and generator. To reduce the noise of the generator set , it is necessary to control the noise source. This article will show you the detailed information about the genset noise source as well as the solution. The main noise source of engine is as follows: Induction noise Exhaust noise Combustion noise Mechanical noise Cooling fans noise The main noise source of generator is as follows: Ventilation noise Electromagnetic noise Mechanical noise Main noise source of engine 1. Air intake and exhaust system noise is the most powerful noise source of the engine. The main source of intake noise is as follows: 1) The pressure fluctuation of air in the intake pipe, which results in low frequency noise. 2) The air flows through the flow area of the intake valve at high speed, which results in high frequency eddy noise. 3) The noise of turbocharger compressor 4) The noise of scavenging p...
