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

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 ...

Converting thrust to horsepower takes some math, but the results are pretty astounding. Here are the staggering power figures ...

The internal combustion engine went through several iterations before we ended up with what we have today. One of these was the "Silent Knight" sleeve engine.

A piston engine is complex, with lots of moving parts; a rotary engine is much simpler, typically with two triangle-shaped rotors attached to an eccentric shaft and no valvetrain whatsoever.

What is a rotary engine? In simple (verging on simplistic) terms, it’s an engine with one or more rotors that rotate – go figure – instead of pistons that reciprocate. The basic principles ...

Without question, the Rolls-Royce Merlin engine is one of the greatest piston pushers ever made. The 27-liter V12 was built in the 1930s and 1940s and would eventually go on to power allied ...

Even as governments continue to push for the transition to zero-emission trucking, work continues on making internal combustion engines greener than ever. The news this year was full of the latest ...
