it need gas it running out of gas that's why...............................
collapsed lifter?
An engine might sound like a diesel at operating temperature if the engine was a diesel or if there was an issue with the manifold. Sometimes gases escaping the manifold cover could cause the engine to sound different.
Engine rod? Engine bearing?
Of what?
Faulty engine
Detonation...Needs to be fixed immediately or will eventually destroy engine.
a loose or slipping belt
IF it is Turbo charged then that would be the turbo.
My bet is you are reading something that is describing the sound of an engine or engines, probably diesel, running off in the distance. In that case, tattoo would be a synonym for drumming sound.
if the oil body is different the sound will change...did you use oil of the same viscosity?
First off you are running a bs engine. So there is your problem right there.
Interesting question. If the car's engine cause the car to reach the speed of sound, causing a shock wave, then the engine did indirectly cause a shock wave. The engine itself creating a shock wave however, is highly unlikely if not impossible. The moving parts in a typical combustion engine do not get anywhere near the speed of sound and any car that would reach the speed of sound would most likely have a jet engine like Thrust SSC.
