3D Printed Four Cylinder Engine

After wanting to make a proper four cylinder engine, this is what I devised.

If you get back to the gas engine, I recommend watching makerj101, he built a 2 stroke combustion engine without a machine shop from scratch. You made the first air engine I’ve seen that was air tight besides Tom Stanton’s diaphragm engine, which isn’t the same as a real one.

This man is single handedly keeping the JB Weld industry alive.

You may also consider having exhaust valves instead of a vent at the bottom, when I made air engines, I found it works better, as when the cylinder is traveling up it won’t have to be fighting compression

It does have a pleasing sound. Not the same as the petrol burner but still has that gentle but solid chug.

Awesome project mate! I've tried many times with making 3d printed solenoid and air engines like you with mixed success. this makes me really want to go back and try again. thanks!

If I had to guess, the engine having to compress any air that is in the cylinders when the piston is travelling up is significantly restricting the maximum rpm of your engine. This is especially true since the engine's compression is so good. Having lower compression while giving it less torque may allow it to achieve a higher rpm. I would recommend adding an exhaust valve and trying again. It shouldn't be as hard to get an exhaust valve to seal, as there is no air behind the valve, and any air entering the cylinder will just be putting pressure on the valve seating it even further into its position.

11:36 Reasons why someone would want stick shift over automatic is that if you know how to use it, the trans will last way longer. (Especially for towing. 7.3 Powerstrokes with stick are indestructible) and because in certain circumstances (most of the time) it's more fun.

great video as always, really liked the camera work on this one.
and of course, great work with the engine, i love seeing the camshaft and valves move as it spins

[AxelDayton]

Homie went with the flat crank💪
Also, i guess this is a call to fix my 2jz engine!

One Russian dude made a electronically driven valve system for his Miata (inspired by the same thing in a Koenigsegg Gemera). I'm pretty sure you are going to look into it once engine is finished.

4:09 - Oh, you don’t know what Karlson is? (Only true dani fans will know this)

[joeterpstra]

I’m sorry to say but the model a engine you showed is a flathead, meaning it has no pushrods, it works by having the valves in the block parallel to the cylinders with the valves riding directly on the lifters, eliminating the need for rocker arms and pushrods, this also means the head is mostly just sealing off the combustion chamber, hence the name flathead. Great video as always, keep it coming👍

This sounds similar to an old tractor engine, love it.

[happycroissant]

He sounds like Jamie off Mythbusters (clarification this is not a roast or anything I just made a connection in my brain lol love the channel)

[victorkrivor]

Just from hearing the engine it looks like you either need higher valve lift, or a taller cam lift. less lift means it can run at lower pressures, with the tradeoff of low rpm, and a high lift/duration camshaft providing higher rpm with higher pressure

[locouk]

Most common firing order is 1342 followed by 1243 with some ford engines.

2 stroke gas engine next? its gonna be fun (they said) maybe also fully 3d printed even without sleeves (2strokes dont need that much compression)

[DelK]

I was kinda hoping that you might choose to experiment with this engine to determine how much work it can do.
I believe that the industry-standard YouTube test for a 3D printed compressed air engine is to ask it to lift a banana from the ground to desk height. This test can be traced back through YouTube history, via Integza, to the YouTube air engine pioneer Tom Stanton.

How have I gone this long in my life and not realize you can measure and mark a copper tube at the same time with your caliper and then cut it so easily/cleanly with that roller pipe cutting tool. Looks so easy compared to how I would have went about it lol. I’m sure it only works for soft materials relative to the calipers otherwise you might mar your caliper grips

Now make a pushrod V8 with a crossplane !
