A 200% More Efficient Internal Combustion Engine
It's commonly understood that the internal combustion engine has to die. Nations have considered banning fuel-burning vehicles beyond a certain future date, though none of these proposals have stuck around. But with increasing pressure on automakers to build more efficient vehicles that put out fewer emissions, the future of the piston engine looks grim.
But now, a team of engineers is investigating a way to make a cleaner, greener internal combustion engine. And their solution involves flipping the standard four-stroke engine on top of itself.
