The existing Tector and Cursor Euro V EEV engines, already recognized by the industry for their reliability, performance and reduced fuel consumption; give way to the new Tector 7 and Cursor 9 Euro VI engines with higher cylinder displacements (the Tector increases from 5.9 to 6.7 liters and the Cursor from 7.8 to 8.7 liters). These engines guarantee more power and more torque with less fuel consumption.
In contrast to Cursor 8, the Cursor 9 Euro VI engine is designed with the latest generation of Common Rail injection installed under the valve cover. This exclusive solution from FPT Industrial allows for significant noise reduction inside the vehicles.
In order to meet the new Euro VI regulations, the engines have adopted the Hi-eSCR (High Efficiency SCR) catalytic reduction system patented by FPT Industrial. This exclusive technology retains optimal engine combustion through the sole intake of fresh air. Cleaning is entirely assured by the after-treatment process, downstream from the engine which, as a consequence, does not require the use of exhaust gas recirculation (EGR). This technology is particularly suited for buses and coaches with rear engines that have high cooling constraints (taking into account that the EGR system needs a minimum of 30% more cooling for the same power). It is also suitable for urban missions characterized by low commercial speeds and frequent stops.
Protected by numerous patents, the innovative Hi-eSCR technology presents a simple solution for the reduction of pollutant emissions as stipulated by Euro VI standards. Hi-eSCR functions without the addition of complex components, without the presence of chemical pollution in the engine and its peripherals and without excessive thermal stress. This results in reduced weight and increased reliability.
All of these benefits, combined with many other improvements, confirm the role of Iveco Bus as a leader in the field. Additional improvements include the modernization and optimization of transmissions and reduced vehicle weight, which allow for a 5 – 10% reduction in fuel consumption compared to Euro V (depending on the model and mission type).
The simple solutions offered by the Iveco Bus Euro VI range, such as the exclusive Hi-eSCR technology and attractive new innovations, have already enticed a high number of customers. Over 500 orders have been received to date, the latest coming from Swiss transport operator Post Auto.
Overall, the new Euro VI range offers a favorable economic balance with lower Total Cost of Ownership, allowing for a rapid return on the investment in new Euro VI technology.
