Iveco announces a Euro 6 solution without EGR
|
|
|
The new Cursor and Tector engines from Iveco will meet the Euro 6 norm without using exhaust gas recirculation technology.
This is the announcement jointly made by par Iveco and Fiat Powertrain Technologies. Alfredo Altavilla, CEO of Iveco, had announced this objective in April 2010, and it now appears that the new reflection on reducing nitrogen oxides is due solely to an improvement in SCR technologies (selective catalytic reduction).
These improvements above all involve the dosage of AdBlue and the control of the thermal properties of the post-treatment of exhaust gases. Several patented innovations considerably refine the precision of the AdBlue/exhaust gases mixture, even taking into account the aging of the SCR catalyser.
The SCR catalyser is integrated into a compact box-unit which also includes the particulate filter (DPF), the diesel oxidation catalyser (DOC) and the cleaning catalyser (CUC).
New Tector and Cursor engines
The new Tector and Cursor engines will also be improved in several areas:
- increase in the injection pressure up to 2200 bar
- new engine control unit
- improvement in engine braking, whose performance will increase by 30% and which will help passive regeneration of the particulate filter (forced regeneration will therefore not be necessary)
- service interval at 150,000 km
Tector range
Tector 4 (4 cylinders, 4.5 litres) : 160, 186 and 206 bhp (580, 680 and 750 Nm)
Tector 6 (6 cylinders, 6.7 litres) : 220, 250, 280 and 320 bhp (800, 850, 1000 and 110 Nm)
Cursor range
Cursor 9 (6 cylinders, 8.7 litres) : 310, 330, 360 and 400 bhp (1300, 1400, 1650 and 1700 Nm)
Cursor 11 (6 cylinders, 11.1 litres) : 420, 460 and 480 bhp (1900, 2150 and 2250 Nm)
Cursor 13 (6 cylinders, 12.9 litres) : 410, 450, 500 and 560 bhp (2100, 2200, 2300 and 2500 Nm)
