Researchers aim to meld the best attributes of both the power-dense two-stroke and the vastly cleaner four-stroke engines.

but only a bit about how engines work. This one inspires us to throw ourselves into the field with reckless abandon. [Huib Visser] built this glass cylinder four-stroke engine and he took great ...

The power stroke extracts work from these gases as they expand and force the piston to BDC. In the exhaust stroke, the exhaust valve is open and the combustion products are expelled from the cylinder.

The Basics Of An Internal Combustion Four-Stroke Engine An internal combustion engine works by repeating the same four steps over and over. These steps are known as strokes, which give the typical ...

He put together this animated infographic to explain, in the simplest terms possible, how an engine works. It runs through everything from the four-stroke cycle to the roles of fuel, oil and air ...

If you do know how engines work ... we'll still try and keep it simple. With very few exceptions every combustion-powered car ...

Early in the history of motorcycling, everything was four-stroke. Four-stroke engines crashed the party in the late '90s, rose to prominence in the mid-2000s and have remained in professional ...
