Abstract—Increased usage of diesel vehicles and equipments are big challenges in terms of pollution and depleting diesel fuel recourses. Significant improvements in diesel emission levels have been achieved in the last 20 years. Development of diesel engine to meet new emission regulations and adopt renewable fuels is a challenging research objective. Automobile industries worldwide are continuing efforts to control emission associated issues both on road and off road diesel vehicles with developed technology for cleaner diesel fuels, quick responding electronic control units, advanced engine design and effective after treatment of exhaust. Some of the NOx control techniques are discussed in this paper.
