Will the stars align for Scuderis high-efficiency split-cycle engine?
May 25, 2009 For more than 100 years people have been trying to come up with an engine design to supercede Nicolaus Otto’s four-stroke internal combustion motor. Scuderi is the latest to take a stab, recently unveiling a prototype of a split-cycle engine that relegates the “suck” and “squeeze” strokes to one cylinder, and the “bang” and “blow” strokes to another – for a claimed efficiency improvement of up to 50%, emission reductions of up to 80% and a power density improvement of up to 70%. Meanwhile, it’s also able to store large amounts of compressed air, allowing it to run as an air/petrol hybrid when cruising. President Obama’s new national efficiency standards represent an opportunity for groups like Scuderi to pitch clever clean engine technology to major manufacturers – but has the split cycle engine got what it takes? President Obama released new, tougher national gas efficiency and emissions standards yesterday – a move that aligns the rest of the country with California’s st
