A two-stroke engine combines intake (“scavenging”) and compression into one stroke, then ignites the charge and exhausts it on the next stroke. Unlike a four-stroke and its every-other-stroke power ...

This means that the high torque efficiency of the two-stroke engine is kept, while the cleanliness and longevity of the four-stroke engine is gained. A win-win scenario. What’s more, the exhaust ...

Two-stroke engines used to be ubiquitous in dirt bike racing, thanks to their lightweight construction and horsepower. Packed in a dirt bike frame, they make a motorcycle playful in the corners and ...

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 ...
