Diesel Engine Air intake Temperature Reduction for Euro V Gaseous Emissions Regulation Compliance

Changes in diesel engine design and calibration contributed to emissions reduction, mainly from Euro III to Euro V the algorithms for the control of smoke and transient response had substantial impact in the calibration concept. In order to follow the diesel engine emissions, the air intake system and air intake cooler must be optimized. The objective of this paper is to show the development of the new air intake package devices design - combined with new CAC (charge air cooler) optimization and new air intake system AIS position in vehicle - to allow intake manifold temperature compliance, using DOE method to the decision.
