    Hello, I don’t use lubricant for my cylinder and switch but if you want, you can use silicone oil, this is the only raw material whicb doesn’t damage the ABS and plastic and ensure a good lubrification. Give up the standard oil or grease or vaseline, it doesn’t work with our lego. Regards.

  4. Weston says:

    Hey nico, how and what lubricant could I use on my switches and cylinders? I have tried so many times to make pneumatic engines and the have failed, prob due to the switch or cylinder. Can you please help me or director in a direction?

    Hi Nico,
    what is step 12&13 in the instructions? It looks like I’ll need 900 blocks of air to make it work, but I only have around 600. I’m sad :).

    Awesome!!!!!!!!!!!!!!!

    You can try on bricklink.com

    I want to make this for a school project. Can you please help me find a place where I can buy all these parts? I have not been able to find them. Thank you!

    I only have an old swich, can i use that too?

    Hey I am almost done but I got a old switch without the holes. I cannot find any switches and bricklink won’t work for me. Any other ideas?

    Hi everybdy,

    After 25 years out of LEGO I’ve just built this simple LPE with my new 8110 Unimog pneumatic cilinders and valves, using a Unimog wheel and tyre as a flywheel. Also built an electric compressor to provide some “petrol” (Two big pumps w/o the springs & one XL motor): not very smooth, but it works.

    It’s easy to double it, using one valve to control two clinders, you’ll only need another big wheel to increase inertia and keep it going ;-D

    Many thanks to you, Nico, let’s try whith your inline three. If I can do it a six I’ll buld a BMW around xD

    Hello, I have tried to build this engine, and I was pretty successful, however, it does not work. It just can’t get over the middle position of the switch. I also tried to modify the switch, but I failed(somehow) and it leaks air now, so I can’t risk my second switch too. I just wanted to ask, can I make this engine work WITHOUT modifying anything at all? And do I need to use the SAME flywheel, or can I use a wheel with the same diameter? This situation is pretty urgent please reply as soon as you can. Thank you!

    is there a way the one can get the lpe to work on a cylender and switch?

    thanks

    In the future I may order some cylinders. What i would do is modify it with gears and a second pump to make it so that it can pump itself and keep going. I would use the gears to make the second pump spin faster than the pump powering it. But the second pump would be a mini one so it would have to go fast to pump anyway.

    You should test with different cylinder and many pumps, the speed is function of the pressure. Regards

  16. zebadiah says:

    if the switch we have is very stiff and does stop the engine, how does one loosen it up?

  17. admin says:

    I don’t think so. Regards

  18. adithya says:

    Hey, can this engine work with a hand crank instead of pneumatics?

  19. admin says:

    Thank you Logan.

  20. Logan says:

    Thanks!

    By the way your models RULE!!!!

  21. admin says:

    I have seen that Bricklink don’t sort the wheel correctly so I have found the wheel with the 8420 catalog

  22. admin says:

    As you can see of the bild of material attached to the post, the reference number is : 32078 Tyre 28×70. Regards

  23. Logan says:

    What is the reference number of the big wheel?

  24. Logan says:

    Where can i get the big wheel?

  25. admin says:

    Yes, because the engine doesn’t start without the inertia of wheel. The inertia of fly-wheel helps the engine in order to get over the middle position of the switch 🙂

  26. admin says:

    Sorry I don’t have. Generally, if building instructions don’t appeared on my blog, I don’t have them 🙂

  27. admin says:

    I use two hand-pump on the video, maybe your switch is too hard ?

  28. Logan says:

    Do you need the big wheel?

  29. Fiona Williams says:

    Hi,

    not sure how else to contact you. My son is very keen to make the caterham csr260. He was wondering if you were able to provide instructions for this car.

    hope you can help,

    Fiona Williams

    it doesent work with lego pump. do you use compressor?

    And THANK YOU!!! Your creations and instructions rule!!!
    CONGRATULATIONS 😀

    […] instance, this classic LPE with 1 cylinder provides 1.3W of power whereas the Nicjasno’s 8 cylinder big block provides 100W, that is […]
