The two-stroke gasoline engine was once a marvel of engineering, offering up huge doses of power in small and lightweight packages. Unfortunately, gas two-strokes also burn oil by design, making them ...

Humans have been showing and telling each other stories since the beginning. The methods may have changed, but the basic drive to communicate what we've learned to our fellow humans remains. Hence, ...

Unless you're really into dirt bikes, you probably haven't touched a two-stroke engine in decades — if you ever have. These mechanically simple motors combine the four strokes we all know and love ...

Traditional Two-Stroke Engine Issues A traditional two-stroke engine has the piston pushing down after firing, moving past an exhaust port and allowing the exhaust gases to leave the chamber.

One of the most significant contributions in the history of propulsion technology came from a 19th-century engineer named Rudolf Diesel. While his idea was patented in the 1890s, it wouldn't be until ...

Anyone who appreciates simplicity of design and efficiency of operation has to like small two-stroke-cycle engines that power construction tools such as cut-off saws, rammers and breakers. Producing ...
