6-24 SPECIAL INSTRUCTIONS FOR -SCR- EXHAUST SYSTEMS E UROCARGO Euro 4/5 If the dosing module is moved, the pipes and electrical wiring must be modified. NOTE 6.5.5 Operations on exhaust pipes The exhaust pipe layout cannot be changed without the approval of IVECO. NOTE The exhaust pipe can be modified paying attention to the following warnings: - Type approved (homologated) counter-pressures must be respected when determining the exhaust pipe route. Form bends with angles greater than 90° and radius of curvature greater than 2.5 times the pipe diameter. Keep the exhaust pipe far enough away from rubber or plastic parts and fit heat shields if necessary.
- It is not permitted to use pipes with diameters, thicknesses and materials other than those used for the original equipment. - It is permitted to use hoses with limited lengths. - In some conversions, it may be necessary to locate the SCR catalytic converter in a new position on the vehicle. Taking into consideration the above conditions, exhaust gas pipe (start of mixer pipe to the SCR plug intake) may be extended up to 3 m. - A further extension of the exhaust gas pipe makes it absolutely necessary to insulate the pipe to avoid excessive heat dispersion with a possible consequent malfunction of the SCR system.
An overall exhaust pipe length of 5 m must not be exceeded under any circumstances. Electrical wiring: - It is only possible to lengthen cables for the temperature sensors. - It is not possible to alter the length of the Nox sensor cable.
