"Pistons stay cooler and less heat is rejected than in current four-stroke diesels, which allows use of a smaller cooling system. Lab testing shows the Achates has 12 to 16 percent better brake-specific fuel efficiency. And if a modern four-stroke diesel's thermodynamic efficiency is 45 to 46 percent, then the Achates engine's "is on the order of 50 percent, and we have a road map to go to 55 percent," says Achates' president, David Johnson."
