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 ...

Everyone generally knows about piston and rotary engines, with many a flamewar having been waged over the pros and cons of each design. The “correct” answer is thus to combine both into a single ...

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 ...

An engine with no crankshaft, where the pistons float on air? It’s not a dream; it’s a free piston engine and it might be the next major advance in car tech. When we think of automotive technology of ...

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 ...

Pistons play the ultimate role in an engine, but despite that, it's still hard to fully wrap your head around all the forces involved. There are plenty of moving parts in an internal combustion engine ...

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, ...

Developing new engines that perform better, weigh less, use less fuel, and meet stringent emissions standards is the primary goal of most engineers and automotive corporations. Companies continually ...

You're at the point in your project where it's time to start building the engine for your car. You're looking online to see what pistons and rebuild kits are available, but the first thing you find ...

The piston skirt and pin account for about 17 percent of the frictional loss in a combustion engine as they are the most difficult to keep lubricated and have the largest contact surfaces. OE ...
