The exhaust from a typical ICE wouldn’t have enough pressure to inflate a tire, so you’d need a compressor. Of course if you had a compressor you’d just use clean air.
If for some reason you used a compressor to compress exhaust gases to fill a tire, it would mostly be the same as filling with air at first.
Exhaust gas is mostly a mix of carbon dioxide and and water vapour, with small amounts of oil residue, and other organic compounds. The water vapour will condense as it cools likely leaving some liquid water in the tire, which won’t cause immediate issues but will cause vibrations which will accelerate wear not just on the tire but possibly the entire suspension.
The organic compounds will cause the rubber to break down over time and the tire will wear out sooner.
Works pretty good to fill up an air mattress, or an airbag offroad jack
Much lower pressure, of course.
The exhaust won’t work, but included with my grandpa’s 1952 8n ford tractor came with an adaptor that you would replace a spark plug on one cylinder, and then pump up a tire using the unburned air fuel mixture into the tire, and running the enigne on the other 3 cylinders.
So the idea is very close to something that was actually done in the real world.
That’s a bomb you’re inflating at that point.
It isn’t very likely to connect with open flame. Tires are pretty well suited for containing air.
In case your rig is on fire for long enough to melt through the very thick tires, that would be dangerous, yes.
The inside of the Hindenburg wasn’t very likely to connect with open flame.
To be fair. No one puts close to a hundred men on a tractor and floats it in the sky (including a dedicated smoking lounge).
All I’m saying there’s a bit of a spread to the risk evaluation.
Tell me you don’t understand the concept of static electricity without telling me you don’t understand the concept of static electricity.
You are not the first to think of that . But I know the adaptor was somewhat common (the 8n is the most popular tractor model ever, and shared an engine with the model A) and i’ve never heard of issues. I’m not sure if that is because nobody talked about it though.
You’d need to either already have the tractor on fire, or somehow have an ignition source for this to happen, but you’ve essentially made a pipe bomb.
Perfect username for that comment ❤️💣
I’m going to use this to fill my motorcycle tires. Fuel vapor bombs on both wheels. Yikes.
They say in a car motorcycle colision the motorcycle always loses. But that’s not true; we could both lose.
Just unplug the injectors first. Or turn the fuel shutoff valve if it’s carbureted.
If you turn the fuel off on a carbureted engine, it won’t run.
Yes, that’s the point. You don’t need it to run to fill a tire: just crank it over a few times with the starter then replace the spark plug and turn the fuel back on.
If you wanted to run the engine while once cylinder is connected to a tire then you’d very quickly overinflate it. Also you’d be running the engine without a cylinder (no spark plug) which is probably always a bad idea and in many cases straight up impossible.
Don’t have to pay for insurance if any little crash becomes deadly!
You’d fill a tire with pretty low pressure, dirty, mostly co2, I’d assume. It probably wouldn’t be drivable and even if it was the small amount of oil and fuel residue would likely damage the inside of the tire after a while.
There are some cool gadgets that you screw into a spark plug socket in the engine and crank it over with the starter to inflate a tire. You’d want to unplug the fuel injector(s) or you’d be turning the tire into a bomb.
I’m not so sure you can get enough pressure from the exhaust
