Lego Pneumatic Engine

A lego pneumatic tractor based on a hot bulb engine Lanz tractor. Features drive, single pneumatic engine, adjustable ignition point, steering and suspended seat.
Here are the new building instructions of the LPE 3i with Lpub and thanks to Ansgar Mährlein.
Features drive by a single cylinder engine, clutch, steering and front suspension.
This new tool has been designed to help builders to know more about their Lego Pneumatic Engines. LPEtool manages all the important data : type of cylinder, number, switch, modified or not, dimensions… The tool calculates the maximun power (at maximun speed and pressure) and the average torque which varies with the rotation of the crankshaft.
For instance, this classic LPE with 1 cylinder provides 1.3W of power whereas the Nicjasno’s 8 cylinder big block provides 100W, that is surprising but with 1500rpm and 6 bars of pressure, it is quite normal. If you have comment, question of suggestion, feel free to comment in this post.
Lot of people ask me to create the instructions of this basic-working smooth engine, so I did. You can download the High Definition PDF or watch the pictures.
