A.Pressure "excursions" (variations in intake manifold mixture flow pressures) are shown here in a trace of pressure vs. time (or crankshaft angle) in only one runner of a single-plane manifold. Since ...

Variable-length intake runners aren't a particularly new concept, but Ferrari's system in its LaFerrari is next-level fascinating. Let Engineering Explained give you the rundown. You see variable ...

OBJECTIVE: Wet flow, pressure excursions, port volume, runner length, plenum volume—all these figure into an engine's overall efficiency. But there's more… Sometimes theory is neat, but sometimes it ...

What’s the first thing you look at when checking out someone’s engine bay? Chances are the intake manifold is at the top of that list. The type of intake manifold can tell a lot about it; stock ...

Your intake manifold. It takes in air and sends it to your engine's combustion chamber. This is basically the start of the combustion process. After all, you can't have combustion without air.

For most gearheads, there's nothing quite thrilling like the roar of a tuned engine and the instant kick of improved acceleration. Of course, buying a muscle car to enjoy lots of raw power and torque ...

Intake manifolds may not be the most well-known automotive components, but that doesn't take away from their importance. These devices are responsible for sending a precise mixture of fuel and air to ...
