Piston-engined fighters ruled the roost for thirty years. A brutal survival of the fittest ensured a rapid evolution of these ...

Sandia National Laboratory led by Sandia researcher Peter Van Blarigan that has been testing physical components of free-piston engines which could be 50% efficient. This is about twice as good as ...

While Tesla, General Motors, Nissan, BMW and other automakers doggedly push to bring battery-powered vehicles into the mainstream, Achates (a-KATE-ezz) Power engineers are betting that an old ...

Remarkable innovations have been made to automotive technology since Karl Benz introduced the world to the "Motorwagen" in 1866 and Henry Ford gave rise to the American auto industry with the Model T ...

Modern piston engines are incorporating advancements such as fuel injection, turbocharging, and electronic controls (like Lycoming's iE2 system). Weight reduction is a key focus; engines like the ...

Moses Karomo is an enthusiastic automotive writer who can talk and write endlessly about cars. He has extensive automotive reporting experience, writing about all manner of automotive topics. He keeps ...

One of the many challenges facing engine designers is the need to increase power output while simultaneously retaining or improving efficiency. Although a four-cylinder engine is still an engineering ...

The opposed-piston engine has been around for over 100 years and is more efficient in almost every way. The engine has no traditional valves, cams, or camshafts, and no head, so it’s simpler and ...

High-output engines live in a world of brutal cylinder pressures, extreme temperatures and razor-thin safety margins, and the humble piston sits at the center of that storm. When power levels climb, ...

Q:I have a 327 in my '31 Ford that features nearly the same cam and components as the one you referenced recently in Pit Stop (Nov. '12). Since a 1.6:1-ratio rocker arm will push the valve a little ...

Just because LEGO Technic is technically a toy doesn’t mean that you cannot do solid engineering with it, like building ...
