If you are a motorhead, an unusual engine will immediately get your attention. Most vehicles today have either an inline or V-shaped configuration, so anything peculiar will immediately stick out. If ...

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 1958 DKW 3=6 looked like a modest family saloon, but its engineering was a quiet rebellion against four-stroke orthodoxy.

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 ...

Gearheads and faithful Jalopnik readers already know the basics of an engine's bore and stroke, but for those that might be new here, let's dip our toes in the shallow end. An engine's bore refers to ...

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 ...

The Industrial Revolution's strides produced many miracles. Advancements in metallurgy and improved technological practices made the mass production of precision parts possible and, with time, ...

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, ...

It looks like GM is working on modernising two-stroke engines by tackling their emissions problem. This could open a whole new chapter for internal combustion. It’s been a while since two-stroke ...
