What causes a noisy diesel engine?
In the diesel engines, the fuel is injected into the already compressed air inside the cylinder.

How do I stop my diesel from knocking?
Detonation can be prevented by any or all of the following techniques:
- retarding ignition timing.
- the use of a fuel with high octane rating, which increases the combustion temperature of the fuel and reduces the proclivity to detonate.
What is wrong with diesel?
Diesel fuel (refined from crude oil) produces many harmful emissions when it is burned, and diesel-fueled vehicles are major sources of harmful pollutants, such as ground-level ozone and particulate matter.

Can you make a diesel exhaust pop?
no you cannot get a diesel to pop on the exhaust, this is because they are much more thermally efficient than a petrol car so as such the exhaust system doesnt get anywhere near as hot as a petrol car. When unburnt fuel comes out of the exhaust of a diesel it just comes out as black smoke.
Should a diesel turbo whistle?
For some people, a turbo whistle can be annoying, but to others, it’s actually desirable! … A turbo whistle shouldn’t be confused with a police siren or dentist’s drill sound – this is likely to be a sign of something more serious, like compressor wheel damage.
Should my engine be quiet?

Will thicker oil reduce engine noise?
When you have low oil volume or low oil pressure, you’ll commonly hear a “clattering noise” coming from the engine’s valves. … Adding more oil will make the noise go away, but it won’t solve the underlying cause of the noisy engine – the oil leak.
