We get spoiled a bit by how amazing noise suppression in modern vehicles is. A modern car rolling 60 MPH down the highway makes almost no engine noise, it's all aerodynamic whoosh and tire noise. Pretty impressive for a machine that's creating several thousand tiny explosions per second.
- mtm 9y agoActually, assuming about 2000 RPM at 60 mph in a 4 cylinder car you are getting more like 17 detonations/second
- asteli 9y agoShame on me! Mixed up my units. Note that we haven't accounted for _n_ cylinders either. For a 4 cylinder engine you'd average ~67/second. :)
- merraksh 9y ago2000 / 60 seconds * 4 cylinders ~ 133 detonations/second.
- asteli 9y agoMaybe in a 4cyl 2-stroke! In 4-stroke engines, a cylinder will fire once every other rev.
