A Lean NOx Trap (LNT) regeneration method that has shown promise regarding its ability to effectively regenerate the LNT, while not adversely affecting the PM emissions, involves the use of Low Temperature Combustion (LTC). LTC is accomplished by highly diluting the intake charge with EGR.1-3* If enough EGR is applied, the in-cylinder air:fuel mixture, and ensuing exhaust, will become rich, thereby regenerating the LNT. This type of highly dilute combustion tends to be more premixed than diffusion, which can lower engine-out PM and NOx emissions. LTC regeneration has been characterized and results are presented comparing this approach to other approaches for rich, in-cylinder diesel combustion for LNT regeneration.
