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, ...

The two-stroke engine is mostly a piece of history today, but there was a time when some of the coolest developments in engine technology were two-cycle engines. Here’s how two-stroke technology rose ...

Hirth and ePropelled develop hybrid propulsion systems for UAVs and drone technology with extended flight duration.

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 ...

The engine is possibly the greatest invention in the history of mankind. Generally speaking, engines are machines that convert one form of energy into mechanical energy and have revolutionized all ...

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 ...

Hirth Engines, a globally recognised leader in two‑stroke engine technology, and ePropelled, an innovator in high‑efficiency intelligent electric propulsion and power‑generation systems, today ...

Name a type of terrain, and someone, somewhere, will figure out a way to race on it. From wood-track ovals and countryside rallies to the pure chaos of the Gumball 3000, humans love to pit themselves ...

The Detroit Diesel Corporation originally launched in 1938 as a division of General Motors, and its main purpose was to build a two-stroke engine that would combine power and versatility in a small ...

If you’re shopping for a new fishing boat or an outboard motor to power it, one of the decisions you’ll have to make is between a 2 stroke vs 4 stroke engine. Unless you’re going electric, this choice ...
