Story Time:

The inspiration:

After the discharge of the LEGO Bugatti Chiron, I felt kinda disenchanted for the dearth of a correct W16 engine. Witch in flip gave me the inspiration to design a brand new pneumatic engine. And figuring out the extra design technicality’s I felt challenged to truly make it work.

The starting course of:

Having challenged myself into, taking an advanced engine and making it work with the restricted quantity of choices LEGO has to supply, I made a decision to inform some individuals about my insane thought. Since some individuals did not imagine I used to be in a position to take action, I needed to off beam show them improper. and here is the place the prototyping begins.

The design course of:

Looking again at it now it was lots simpler than I initially anticipated. after lower than a handful of prototypes and about 1,5 hours of labor, I managed to provide you with a design that’s pretty just like what you see now, nevertheless removed from completed. The design just about went in 2 elements, first I began with the body for the pistons. When that was carried out I debated on how one can drive the switches, Initially I needed to make use of a sliding design But on account of measurement constraints I used to be compelled to make use of a camshaft design.

The construct course of:

After ordering all of the elements I set to work on the ultimate design. (imagine it or not I did not have a full design earlier than ordering elements) So I used the premise of the prototypes, improved upon them, and eventually discover out a option to merge the switches with the cilinders with out it wanting prefer it was simply “caught on prime of there”. But oh boy then got here the largest problem…. the pneumatic hose. man that was an actual psychological problem, Just strive it for your self: 16 cilinders underneath four completely different angles on the crankshaft, 2 rows of four switches, a extremely small house to work inside, and to prime all of it of If you make a mistake you may must take half the engine aside with the intention to repair it.

Timing the engine:

Now in the event you suppose watching the finals of the tremendous bowl is nerve-racking it is best to think about this: I lastly completed the engine to the purpose of timing the switches, and with the primary check the engine ran in 2 completely different instructions.(you possibly can really see this check go improper within the video) After some investigation I fortunately found out I did not wire the pneumatic hose improperly, as an alternative It was only a matter of getting 2 switches swap on the improper second. so little tweaking of the camshaft did the trick.

Final testing:

Then off beam there may be the ultimate check and the o so joyful face I made when the engine first ran. Man what a reduction, and with a little bit of optimizing I managed to get a prime rpm of 540 for now. (When creating the directions I noticed I made a mistake deadly for getting excessive rpm. I DIDN’T drill out the primary pneumatic inlet, so i used to be nonetheless restricted to the tiny gap lego places of their elements reasonably then the bodily restrict of the engine.

The constructing directions:

Honestly the constructing directions the place an afterthought. When I began I had solely the intention to create a tremendous piece of engineering, and filming it for everybody to see on-line.

So how come these directions? Well I’ve tried earlier than to create directions with none succes, so I assumed lets come again to that however this time study the software program and make a profitable instruction for everybody to make use of.

But what concerning the worth? Lets be sincere, designing a machine like that is no straightforward job. And on prime of that I do not need everybody to simply attempt to construct this solely to determine they do not have the technical knowhow to get this engine to work. In different phrases: I need to demotivate the individuals that aren’t decided.
