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 ...

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 ...

Some of the world’s most complicated engines were created to achieve a specific objective. These engines were built to ...

The R-4360 Wasp Major was the peak of reciprocating aircraft engines, a 28-cylinder monster capable of 4,000 horsepower. In this breakdown, we trace how piston engines evolved from the Wright brothers ...

The newly formed organization will host a series of meetings of its members to exchange research results, insights and ideas regarding opposed-piston engines with hydrogen combustion. Several ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

The first recognizable internal combustion engine was developed by Nikolaus Otto in 1861. Since then, the gasoline-powered engine has evolved immensely. However, the principles that underlie how ...

Mazda's five-decade-long, largely futile efforts on behalf of the rotary engine demonstrate how difficult it is to unseat the conventional piston engine. Yet new concepts continue to emerge, ...

Technical manoeuvring to push regulatory boundaries for the slightest performance edge without actually breaking any rules is ...

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 ...

There’s just something special, accessible, and enjoyable about car stuff made from Legos. Whether they’re transmissions, suspension systems, or other mechanical goodness, it’s fascinating to see the ...

Constantly low on oil, getting bad fumes, or is your engine not as peppy as it once was? Your car's engine may be ...
