The crankshafts are linked together by gears at one end of the engine
The added economy comes from efficiency of combustion.
Remember a typical internal combustion engine is only about 25% energy efficient. Achates can achieve 40% due to much higher compression (like a diesel), less energy lost to valve train, etc. better mixture control based on the 2-stroke port designs and dual injectors, recovery of lost energy via turbocharging, etc.
It's not a 6-cylinder; it's a 6-piston in 3-cylinder engine. Instead of the head "resisting" the pressure of combustion, the "fire" is in the middle of the cylinder and pistons on either side of the burning gas are forced outwards.

Achates Opposed Piston engine (a bit like a resonance watch?)
Today I read about a company based here in San Diego (and Detroit) which is developing 1-3 cylinder engines to work in hybrid vehicles and military or commercial applications (like Auxiliary Power Units, compressors, generators, etc). Earlier in the 20th ...
Very interesting.
I really would like to see present and future applications for that kind of engine. Thanks for sharing. Vte
But the oil would fill the chamber
They’d have to re-engineer a horizontal configuration. Cheers Cazalea
This reminds me a bit of the old Detroit...
...diesel engines. 2-stroke compression ignition and you guessed it, supercharged AND turbocharged. powerful four cylinder. Lovely sound too: https://m. There were also some aircraft engines like this.
