Engine construction plans by Martin Ohrndorf

Detailed parts lists

Comprehensible instructions

Clear drawings

The construction plans contain illustrations of the individual parts as well as views and sections of the complete engine.

A multi-page construction description, parts lists of all parts as well as reference addresses of ball bearings, gear wheels etc. round off the construction plans.

At the boxer engine you can see extracts of the construction plan. The construction plans of the other engines are designed in the same way.

Build your combustion engine

All Ohrndorf engines are multi-cylinder 4-stroke glow igniters, which were developed by Martin Ohrndorf. Except for the carburetors, no individual parts from other engines were used, each component is his own design.

With the detailed construction plans available here, you can reproduce the Ohrdorf motors yourself.
