Sound is a vital part of the internal-combustion-engine experience, as well as many engine arrangements have their own unique audio.
There are numerous reasons that, yet one of one of the most important factors in an engine's sound is just how equally the exhaust pulses get to the tailpipes. Evenly spaced exhaust pulses often tend to cause higher-pitched, smoother audio. Erratically spaced pulses in deeper, a lot more complicated, as well as angrier noise.
In this episode, nerdy automobile journalist Jason Cammisa gives a simplistic review of the science behind this, explaining how the consistency can be determined by the crankshaft or the exhaust– and offering examples of each.
He covers 4-cylinders (the Honda S2000's equal-length headers contrasted to the Subaru WRX STI's burble), V6 engines (the Nissan VQ versus Ford EcoBoost), V8 (the Ferrari flat-plane crank V-8 versus an American cross-plane V8), V10 engines (the Lamborghini Gallardo even-fire V10 versus the LP560's odd-fire, which seems like 2 5-cylinders), as well as the Mercedes-Benz V12 with equal-length headers versus the manufacturing facility exhaust.
