Machining A Two-Stroke Engine Out Of Aluminium

Recently [Camden Bowen] took a swing at machining a two-stroke engine out of billet aluminium, following adventures in 3D printing such an engine, as well as building one out of parts largely sourc…

Its been 20 years since I lost my #trabant to an accident but i still miss its #twostroke glory. It was so much fun to drive and tinker with.

Two German engineers. Two 50cc two-strokes. One and a half years riding the Australian Outback.

Bea & Helmut from Time to Ride on tackling remote tracks, living at 50cc, and the unexpected effect those little bikes had on the people they met.

Strong, fun conversation.

A prototype two-stroke internal combustion engine that uses a rotary exhaust valve eliminates the need for oil mixed with fuel, resulting in cleaner and more efficient combustion. It can therefore be run using natural gas, hydrogen, and biodiesel as well as gas.

One small change solves the two-stroke engine's biggest problems

The defining characteristic of a two-stroke engine is to fire (combust) every time the piston is at top dead center. This makes them highly power dense, but also notoriously makes two-stroke engines dirty, inefficient, and not prone to long lifespans.
