Hi: Sounds like your internal compressor mounting springs have broken or broken loose and your internal motor is having at it at full bang on start up! Sounds awful don't it!!!!!,,,,, if not that then look at your fan motor supports/belts/bracketry/& such. Equally as offensive when terrible clatter comes in to play. Hope this helps: Jimiwane
The fuel is ignited by compression and not by a spark plug. The compression of the cylinders is much higher than in a gas engine. The fuel must be compressed to the point at which it will ignite. This cause the noise you hear from a diesel engine.
Indirect injection (IDI) produces less noise.
Diesel engines detonate. Diesel has more potential energy than gasoline, instead of burning evenly, diesel explodes creating a knock or rattle noise.
Resonance is the answer.
if its a turbo that's it,if not don't know
maybe not CAUSE noise pollution,but they sure do affect it. ;-)

Diesel trains are louder than electric trains because you the noise that the diesel engine makes, which is louder than the electric engine.
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
Normal cause is electrical noise in the APPS circuit, dirty battery cables, dirty ground locations, and bad alternator brushes can all be the cause.
A bad compressor belt can cause a whistling noise while running the air conditioner. A bad engine can also cause this noise.
What would cause a grinding noise after a tire is replaced and the brakes are not worn?
