Piston rings are small, but they play an essential role in the performance of internal combustion engines, and their engineering is nothing short of brilliant. These cleverly designed components may ...

The Hydrogen Opposed Piston Engine Working Group will host a series of meetings of its members to exchange research results, insights and ideas regarding opposed-piston engines with hydrogen ...

Compression ignition engines ignite the air-fuel mixture by heat and compression rather than the spark plug igniter of a gasoline engine. For this to work effectively, the engine needs to have a ...

In this video, you'll see the different types of engines and propulsion systems used for aircraft, my favorite ones: Turbojet ...

The world's largest piston engine is the Wärtsilä RT-Flex96C inline-14 diesel, which generates 110,000 hp, stands 44 feet ...

So what is an opposed-piston engine and how does it work ? New auto trend picks up speed: Small but mighty engines. Need a break? Play the USA TODAY Daily Crossword Puzzle.

Achates' opposed piston engine is a two-cycle, 2.7-liter, three-cylinder with six pistons arranged in a pair per cylinder, working against each other rather than each piston in its own cylinder ...

Free piston engines could achieve efficiencies of 50% which is almost double a regular gas combustion engine. However, new super efficient diesel engines could be even better, plus diesels would be ...

I’m thinking that part of the reason the engine ran at 1.5 bar of steam better than 2 bar of compressed air; is condensing water both lubricated and sealed the piston.

Put 50 engine builders in a room and you will get 50 different opinions on how to assemble an engine. Rolling piston rings on can and will distort the rings. Not everyone agrees with this.

The earliest piston engines typically had only one cylinder, and at best, produced horsepower measured in single digits. But once you have a working engine, it’s a relatively short step to ad… ...
