Iveco has bucked the industry trend and launched a Euro-6 variant of its Cursor and Tector engines that does not require exhaust gas recirculation (EGR).
Iveco chief executive Alfredo Altavilla says: "EGR as a technology has its place in the transport sector, but for heavy CVs that may significantly exceed more than one million kilometres during the course of their life, the technology that reduces fuel consumption and additional operating costs to their minimum is the correct technical choice."
The engines, developed by sister firm FPT Industrial, have improved combustion efficiency, a new ECU, and use selective catalytic reduction (SCR) only to achieve the Euro-6 emissions targets. The key to this is new after-treatment hardware that enables precise AdBlue dosing; and ammonia and NOx sensor technology for accurate exhaust gas sensing, enabling adaptive AdBlue dosing to compensate for any ageing of the SCR catalyst.
Altavilla adds: "It is clear that Euro-6 vehicles will be more expensive; technology has a price and a value. We will introduce suitably equipped vehicles when our customers ask us to do so."
