Building and Testing Different LEGO Vacuum Engines

Unlike my last two videos about pneumatic engines, this time i built a few vacuum engines.

the most simple lego engine ive ever seen was the 2nd one

If you want a better seal on your airflow, put a Lego tire on the vacuum.

i am watching this rather than doing my english work i am about to fail the class but this is more important

[Metal-Sonic]

1:45 it actually needs a small spin to start, just like a real engine, you are doing the work of the starter manually

This man has the most silent vaccuum cleaner ever

Can you show us how you made the first one in depth please

If the three cylinder ran at 1/3 the RPM of the one cylinder, then the efficiency of 3 cylinders would be equal to one cylinder however you would be able to measure the improved efficiency of using three cylinders instead of a single cylinder from the difference of the three cylinder RPM verses that of 1/3 of the single cylinder

Hey, i have a question. How do multiple cylinders help in increased speed?

i finally found the piston's rod thingy (5x3), and it works really great even when unlubed. thanks

It would be better if you used a lego tyre in the vacuum mouth for a better seal. (Tested by myself)

Dude if someone just made four of the second one and attach all the air ways to one at the middle you could make a car! (And if you found a way to control the suction you could control the speed and if you reverse suctioned you’d be able to reverse)😳✊😎🏎

Does 2nd and 3rd ones have a speed difference

[adampasieka]

i made a working prototype of the second engine with another one stacked right under it (180 degree offset connected with chains or gears) which takes the exhaust of the top engine, its great i think you should build one but be sure to change the crankshaft to be 2 studs instead 3 and put it 1 stud higher on the piston's axle as the timg would be messed up!!!

I Think you have to add a gauge or throttle lever

[judybuessing]

the first working lego caccum engine i have made!

[roplayer]

Thanks for the engenes
I am curently building one with a bad valve design so ill use the first engenes valve config

[_Gaming]

Can you make a tutorial on the second one, the one vertical cylinder

[jachinnoheman]

Can you make a v12 engine with these pistons please

[ermondem]

Is it possible to make the 3rd engine a 2 stroke engine?
