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.
