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 ...

The 1960s were a time that saw muscle cars with the best names and automakers racing for horsepower supremacy. While drag racers often turned to large displacement big-block engines for power, others ...

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 ...

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 ...
