Why do V8 engines rumble?
The short answer is the growl comes from the fact that most v8 engines use a cross-plane crankshaft. Cross planes have each connecting rod journal 90 degrees apart, this leads to the engine not firing each cylinder with equal time in between each pulse leading to the burble sound.
Why do v8s sound the way they do?
Each pulse makes a tone, which combined with the other pulses forms a harmonic series. The same thing happens in all engines, but it’s the irregular firing sequence that gives a big V8 its distinctive throbbing sound.
What causes exhaust burble?
Essentially, the sudden easing off the throttle causes an immediate decrease in exhaust emissions to the degree that atmospheric pressure surrounding the exhaust pipe pushes cool air up into the exhaust system. This air collides with the warm exhaust gasses and creates a rumbling not unlike thunder.
Why are v8s dying?
If you can deliver equal power than a V8 and higher fuel mileage without sacrificing reliability or longevity, you sell more cars. Since selling more cars is the only goal of car manufacturers, that’s why the V8 is dying.
Is a V6 louder than a V8?
v8 is just naturally louder than a 6. regardless of how the engine is made.
What is the loudest V8?
But the high(er) performance variants of the mid-engine Vette aren’t on the market yet, so this 2019 ZR1 is still the loudest Targa we’ve tested. It—or really its 755-hp supercharged V-8—sang a 99-decibel swan song for the engine layout Chevrolet had relied upon since 1953 for its all-American sports car.
Why does a V8 sound better than a v12?
The large pistons with the larger intake and exhaust valves sing a tune no other engine can match. BTW the larger valves and combustion chamber which is the engine heads and intake, exhaust system is bigger so engine has more air flow which also helps the sound of the V8.
Why do 4 cylinder engines sound bad?
Four cylinder engines are less smooth than V6s and FAR less smooth than inline sixes. This causes more vibration in the car, which makes it louder.
