A method for improving NOx conversion efficiency of a urea base SCR catalyst is presented. Since efficiency is reduced by the presence of hydrocarbons in the catalyst, the method proposes to regenerate the SCR by maintaining its temperature above the boiling point of hydrocarbons for a sufficient period of time to free up catalyst storage sites. The regeneration process is followed by over-injection of ammonia to replenish the ammonia released from the SCR catalyst due to high regeneration temperatures.

The present invention pertains to a MOS type differential buffer circuit. The buffer proposed herein utilizes capacitive coupling to apply small AC signals to an amplifying current source to mitigate attenuation owing to body effect and output impedance, among other things, in an associated follower component. The proposed circuit does not, however, promote an increase in current and / or power dissipation. Additionally, the circuit allows a desired gain to be achieved while maintaining a relatively constant output impedance, compared to a simple differential source follower.
