Automotive giant General Motors has filed patents for a two-stroke engine of the type whose excess emissions took it off the road decades ago as a technology seen as having no future.The patent is for ...

General Motors (GM) is revisiting a technology long thought to be obsolete in the world of cars: the two-stroke engine.

General Motors may not be building a bike engine, but this two-stroke concept has real potential for motorcycle engineering.

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 ...

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 ...

Now, General Motors (GM) has gone and filed a new patent application for... a two-stroke engine. The document explicitly mentions use in hybrid vehicles, immediately raising a question: Is GM ...

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 ...

Renault has unveiled a turbocharged and supercharged two-cylinder, two-stroke diesel engine. This prototype version of the motor was showcased at Renault’s Innovations@Renault event in Paris. This ...

What if the engine of the future wasn’t just a dream, but a reality? Imagine a power source that combines the raw, exhilarating performance of a two-stroke engine with innovative efficiency, ...

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 ...
