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 ...

Have you ever wondered why you need to add oil to your chainsaw’s fuel supply? Or why some dirt bikes have a higher pitched exhaust note than others? We’ve all been burdened with yard work or been ...

Editor’s Note: This article previously appeared in a different format as part of The Atlantic’s Notes section, retired in 2021. In response to the item immediately below, which kicked off this Thread, ...

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 ...

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 ...

We love ourselves a good oddball engine, and tiny, scrappy Mazda certainly must be responsible for more such engine concept patents per market-capitalization dollar than any other. We just discovered ...

Ahh, two-stroke engines. Many people associate the sound (and smell) of a two-stroke with yard equipment, but for motorcycle fans, it signifies something else entirely – performance. See, before ...

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 ...

Conventional wisdom suggests that our faithful internal combustion (IC) engines are heading the way of the buggy whip. The lithium-ion battery has arrived, emissions standards are tightening, and ...

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 ...

Dim’s fascination with cars began when he was just six. Born into a family of car enthusiasts and racing drivers, he started learning basic mechanics and driving from an early age. While he loves ...
