It replaces the combustion engine with its multiple pistons thrusting up and down with a single piston that goes side-to-side. It has fewer than 20 parts and a single action, the company said. In tests by the German engineering company FEV, the Aquarius engine's efficiency was more than double that of traditional engines.
The invention from Israeli-based Aquarius Engines is currently being discussed by France's Peugeot, the firm said. Aquarius says the cost of the engine will be as low as $100 (92 euros).
Hmmm. Best I have had from mine was 663 miles before I chickened out and filled it up but my C5 is notoriously crap where consumption is concerned.According to the firm, the engine can allow cars to travel more than 1,600 kilometres (990 miles) on a single tank of fuel, more than double current distances.
