Method for Rich Pulse Control of Diesel Engines

Abstract: 

A combustion control method for the rich pulse control of Diesel engines with Lean NO.sub.X Trap systems includes identifying areas within a Diesel engine operating regime in which reduced recirculated exhaust gas and air with increased pre-mixed combustion is effective in providing fuel rich combustion, and a second, lower load, region in which low temperature combustion is particularly desirable.
