Achates Power is reviving the century-old opposed piston layout to make gas-powered cars more efficient.An opposed-piston engine is a reciprocating internal combustion engine in which each cylinder has a piston at both ends, and no cylinder head.

It replaces the four-stroke engine’s valvetrain with open intake and the exhaust ports, eliminating the friction and complexity of the camshaft and valves.

The team of engineers is investigating a way to make the cleaner, greener internal combustion engine. Their solution involves flipping the standard four-stroke engine on top of itself.

Opposed piston engines should not be confused with flat engines, which are horizontally opposed with one piston per cylinder, and cylinder heads.
