http://www.gizmag.com 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?en gizmag.com http://www.gizmag.com/will-the-stars-align-for-scuderis-high-efficiency-split-cycle-engine/11783/#comment-2572 http://www.gizmag.com/will-the-stars-align-for-scuderis-high-efficiency-split-cycle-engine/11783/#comment-2572 Tue, 26 May 2009 00:33:37 -0500 http://www.gizmag.com/will-the-stars-align-for-scuderis-high-efficiency-split-cycle-engine/11783/#comment-2563 http://www.gizmag.com/will-the-stars-align-for-scuderis-high-efficiency-split-cycle-engine/11783/#comment-2563 Mon, 25 May 2009 18:42:28 -0500 http://www.gizmag.com/will-the-stars-align-for-scuderis-high-efficiency-split-cycle-engine/11783/#comment-2560 http://www.gizmag.com/will-the-stars-align-for-scuderis-high-efficiency-split-cycle-engine/11783/#comment-2560 Mon, 25 May 2009 15:07:48 -0500
