Since the dawn of the internal combustion engine, the search for power has been paramount in internal combustion engine development and advancements over the years. Ranging in all sorts of different ...

For decades, engineers have used small-displacement engines to prove that raw capacity is not the only path to victory. By pairing compact cylinders with clever breathing, high revs, and forced ...

Astron aerospace has shown a partial prototype of a new rotary combustion engine it claims runs at an extraordinary 60% thermal efficiency, burning totally clean with zero NOx emissions and nothing ...

The rapid build-out of AI data centers is creating an unexpected surge in demand for reciprocating internal combustion engines, as developers struggle to secure reliable grid power in time to meet ...

Small internal combustion engines usually keep things simple, relying on carburetors to handle metering the correct amount of fuel and air. Recently, [Carlos Takeshita] decided his small engine could ...

A better mousetrap? Even now, as electrification seems poised to end the internal combustion engine’s long run as the transportation motivator of choice, enterprising tinkerers continue to propose ...

Carbon emission-free engines that burn hydrogen increasingly look like a viable technology for vehicles that range from race cars to cement mixers. The motorsport department at Austrian automotive ...
