The development and the current situation of lean burn techniques on gasoline engine are expounded and the characteristics of three different lean burn system and emission control problems are also introduced in this paper. And then the research progress, advantages and disadvantages of the NOx emission control techniques which includes three catalytic technologies (NOx direct catalytic cracking, Selective Catalyctic Reduction, Lean-NOx- Trap ) and Exhaust Gas Recirculation are analyzed. And the direction of improve Vehicle Economy and emissions are discussed.
