The most significant factor that affects cylinder-to-cylinder air/fuel distribution in the intake manifold is the spatial relationship between the runner openings into the plenum and the ...

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 ...

This race engine builder just built a rig to test his fuel system. It features 3D-printed parts and a clear intake manifold.

Implausible Signal P2014 - Intake Manifold Runner Position Sensor/Switch Circuit P2004 - Intake Manifold Runner Control Stuck Open For many years, manufacturers had to choose between long-runner ...

But these systems usually just contain a valve that diverts air from a short to a long intake runner. Ferrari's system ... intake valve and inside the manifold. It's a fascinating system that ...

or in the intake runner in the case of port injection. This requires intake manifolds with vastly different designs when you look at inlets, plenums, and runners. Each of these parts also has a ...

Now that might seem like a large boost differential, but Rick says he ran each manifold several ... pulling air through the intake. Great care is taken to ensure each runner flows equal for ...

With a longer runner, the pressure wave has to travel ... So you have to make the intake manifold shorter so the pulse can get there." Per Autozine, the runners in the 300SL were long to help ...

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.

In a recent test on an Opti-flo hot runner system equipped with MeltFlipper technology from Beaumont Technologies Inc., new process parameters were established in a fraction of the time normally spent ...
