It is quite ironic that internal combustion engines (ICEs) have remained basically the same for more than one hundred years. It is only now – when they are allegedly on the verge of disappearing – ...

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 ...

Not every engine has a set of pistons that move up and down in a cylinder. The Wankel, or rotary engine, delivers its power with rotational force rather than a reciprocating mass that hammers out ...

The internal combustion engine, for all its mechanical sophistication, still runs on a 19th-century mechanical idea: pistons rising and falling, a crankshaft spinning, a steam-age architecture ...

In a world dominated by pistons, the rotary engine was something different for motorists. It was the vision of German engineer Felix Wankel, built on the belief that the up-and-down motion of pistons ...

When people defend that internal combustion engines (ICEs) still have a role to play in personal transportation, they are correct. Having an electric motor driving the wheels does not necessarily ...
