I have been pondering this a while, and I started to put some math to it to make sure it makes sense.
Does it have any real application? Maybe.
Let's look at the application first.
I want to clean out my truck, but I'm not in the city and I'm not near my home or electricity because I'm out in a remote area testing the limits of my LC and I have encountered dry granular products all around me. These dry granular products have been mixed with water to create a sticky paste and will frequently attach to my footwear.
When I enter and exit my LC, some of this paste rubs off on the carpet on the floor and areas around my feet as well as those of my passengers.
I want to set up a way to clean out my LC in order to preserve it and to make sure my bride is able to enjoy a clean ride while we enjoy the outdoors.
I want to design a central vacuum system in order to vacuum the dirt out of the carpets and seats of the truck, using nothing but the things we carry with us.
I propose to attach an adapter to the side of the intake filter housing where a hose can be attached.
This hose needs to be about 1-1/2" in diameter and about 20 feet long in order to reach everywhere in the truck.
The intake filter is just like the cyclone part of the vacuum system (think Dyson) and the filter element filters the dust just like your vacuum cleaner.
Let's look at the number to determine if this will work.
Materials like this need to convey with about 4000 FPM in the line and possibly as much as 5000 FPM to achieve a face velocity at the vacuum hose attachment of a minimum of 500 FPM.
1-1/2" hose = 1.7614587 in2 = 0.012271846 ft2
Attachment with 1/2" x 4" wide opening= 2.0in2 = 0.01388889 ft2
4000 ft/m x 0.012271846 ft2 = 49.087 CFM
4.5L Engine uses 4.5L every two rotations (because it's a four-stroke engine).
4.5L = 0.158916 ft3
49.087 ft3/m/0.158916 ft3/2RPM = 308.886 RPM x 2 = 617.77 RPM
So, the 4.5L engine will produce 49 CFM at 617 RPM to achieve 4000 FPM in a 1-1/2" hose.
Since the engine is a positive displacement "blower" and it is capable of -17" hg suction at idle, it will be plenty for this application.
I don't know about anyone else, but we have a couple dead vacuum cleaners around that we could grab hoses and adapters from.
So, anyone have any suggestions on connecting to the intake canister? I would want it to be a quick connect with a shut off valve so it won't allow in water.
It cannot interfere with a snorkel.
It needs to have an impact plate where the materials enter the canister so the conveyed materials don't damage the filter itself and suck all the dirt directly into the engine.
The Tuna Can can be removed after each cleaning in order to dump the heavy stuff sucked up.
It may cause the filter change out to be a little sooner, but if you have the washable element, it's that much better, right?
Probably best if it attaches to the actual intake on the LC, so maybe in the fender?
How many people would be up for a kit for their LC?
A lot of folks like to go to the beach. Sand ends up in the truck.
Sand is about 100 LB/ft3. It needs about 6000 FPM pickup velocity.
So, maybe you'd need a throttle to boost the RPM to 927 and hold it there.
Now, if my truck could have an IVS as well as door mounted fuel bladders, I think my life may be complete.
Does it have any real application? Maybe.
