SwRI develops D-EGR demonstrator highlighting fuel-efficient, cost-effective engine; 10% and above fuel economy improvements

Green Car Congress

D-EGR is an engine and control concept that combines fuel reforming to produce hydrogen with high levels of exhaust gas recirculation (EGR) to achieve very high levels of thermal efficiency. liter engine running as a full D-EGR engine from idle to full load, delivering more than 42% brake thermal efficiency with ultra-low exhaust emissions.

Achates OPGCI project targeting 50% fuel efficiency gains over downsized GDI engine at reduced cost

Green Car Congress

At idle and low loads, rebreathing of hot exhaust gases provided stable compression ignition with very low engine-out NO x and PM emissions. Rebreathing enabled reduced boost pressure, while greatly increasing exhaust temperature. bar was measured at 2000 rpm, with 17.4 MAP was reduced to minimize boost parasitics.
