We all know how a conventional internal combustion engine works, with a piston and a crankshaft. But that’s by no means the only way to make an engine, and one of the slightly more unusual ...

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 ...

German aerospace researchers are showing off a high-efficiency powerplant concept which combines geared-fan architecture with a piston-engine core. While unlikely to enter service before 2050, the ...

Despite being in use for more than a century, combustion engines are still way to complex and inefficient in turing fossil fuel to mechanical work. Naturally, engineers have been battling their way ...

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 ...
