Frequently asked questions
Q: When will the new exhaust-gas regulations become effective?
A: Euro 4 is valid since 1st October 2005 for newly homologated vehicles and on 1st October 2006 for all newly registered vehicles. Euro 5 is due to come into force on 1st October 2008 and 1st October 2009 respectively.

Q: Why is MAN offering two exhaust-gas technologies for Euro 4 and Euro 5?
A: MAN's solution with EGR and the PM-KAT® Filter is a technically and economically compelling system. MAN will also offer this system for Euro 5 well before the legal deadline. MAN's AdBlue® SCR technology is already available for customers who want a Euro 5 solution today.

Q: Which solution does MAN recommend?
A: The MAN system with EGR and PM-KAT® filter is predestined for customers who do little driving on freeways and for whom frame space plays a significant role (construction, public utilities, special vehicles), and who transport particularly heavy payloads (tank and silo branches). SCR technology is particularly recommended for vehicles that transport payloads over long distances on German freeways and in Switzerland. Companies that take advantage of such technology profit from the lower toll and road-use fees for Euro 5 vehicles.

Q: How does the PM-KAT® filter work?
A: In the PM-KAT® filter particulate separation is effected by the specially triggered formation of turbulences during the deflection of exhaust gases in the separator and their passage through the sintered metal fabric. The dissolution of the particulates retained in the fabric is the result of a permanent chemical reaction brought about with the aid of the NO2 formed in the oxidising catalytic converter.

Q: What are the advantages of exhaust gas recirculation (EGR)?
A: EGR lowers combustion temperature through a cooled mixture of exhaust and fresh air, which reduces the proportion of nitric oxide in the exhaust. This simultaneously increases the proportion of particulate matter. To achieve the required values, the downstream MAN PM-KAT® filter is then required.

Q: What is AdBlue®?
A: AdBlue® is a colourless, odourless and completely harmless urea solution of utmost purity. With the aid of AdBlue® harmful oxides of nitrogen are chemically converted into nitrogen and water vapour in a process taking place downstream of the engine.

Q: What is the consumption of AdBlue®?
A: AdBlue® consumption is estimated to be 4 % of diesel consumption in Euro 4 vehicles and approx. 6 % in Euro 5 vehicles.

Q: What is the On-Board-Diagnosis OBD 1 system?
A: The OBD is a diagnostic system that monitors emission-relevant components. Required as of October 1, 2006, OBD is meant to ensure compliance to emission control standards not only upon registration, but throughout vehicle lifetime. MAN furnishes both its Euro 4 and Euro 5 trucks with OBD 1.
