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 ...

We've seen many engine configurations come and go, with some being more noteworthy than others and some being just outrageous. Honda attempted to modify the shapes of the pistons used in its engine, ...

Two-stroke engines have steadily fallen out of favor over the last 50 years or so. While they sport great power-to-weight ratios and are often much simpler mechanically than their four-stroke ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, ...

As you may know, an engine's compression ratio is directly linked to its combustion efficiency. All else being equal, higher-compression engines tend to make more power while offering better fuel ...
