At 2040 RPM, each intake valve opens 17 times per second.  In the 59 ms
between valve openings, a droplet starting at rest would only drop 0.7
inches. Of course, there's a lot of turbulence in there, so things get
mixed up. There's simply not enough time for the fuel to puddle. It
just hangs around as a mist, waiting to get sucked into the cylinder.
