General Motors may not be building a bike engine, but this two-stroke concept has real potential for motorcycle engineering. General Motors and two-stroke engines aren’t exactly two things you expect ...

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 ...

GM has filed a patent application for a two-stroke engine valve system. The patent application is tagged with patent number US 2025/0354528 A1 and was filed with the United States Patent and Trademark ...

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 ...

Name a type of terrain, and someone, somewhere, will figure out a way to race on it. From wood-track ovals and countryside rallies to the pure chaos of the Gumball 3000, humans love to pit themselves ...

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 ...
