(2) Is a new idea, I'm sure you've all seen those new cyclonicfilter free vacuum cleaners, that always maintain 100% suction, or so they
say. Could an air plenum be designed on the same principle so that dust and
gravel get separated from the main airflow and get ducted out a side tube,
leaving the main air stream to go to the engine.
Just ideas guys,
Michael.
Not such a new idea, Michael, but a good one nonetheless. I've got a buddy here with a Quickie that uses this technique. The air comes in and has to travel around a radius under the cowl. The engine picks up air from inside the radius, and the extra exits at the rear of the curve through an opening that blows across the engine.
I have enough room that I'll use the technique that Chrysler used in my Dakota pick-up. The air comes into a large box, with a large, flat, pleated filter covering the top. Air comes into the box and slows down. Heavy stuff drops to the bottom, and engine air get sucked out the top. I have to vacuum a few tablespoons of sand out of the box whenever I change the filter, and I don't do any off-roading.
