BlueTec exhaust gas cleaning system The BlueTec exhaust gas cleaning system essentially comprises a supply tank, a catalytic converter and an AdBlue metering system. It is monitored and controlled electronically. Pollutants in the exhaust gas are converted into environmentally friendly substances through a combination of the addition of AdBlue and the effect of the catalytic converter in the exhaust silencer. To function correctly, the BlueTec exhaust gas cleaning system requires the addition of a reducing agent (AdBlue). The addition of AdBlue does not form part of the routine scope of bus maintenance – it is the responsibility of the vehicle operators to ensure that the AdBlue supply tank is regularly replenished. Filling and operating the bus with AdBlue is mandatory for compliance with emission regulations and is thus one of the conditions for the road traffic approval of the bus. The road traffic approval of the bus will be invalidated if the bus is op-
erated without AdBlue. Legally, the bus would no longer be permitted to be operated on public roads. In some countries, operation of the bus without AdBlue may be considered to be a criminal offence or a violation of administrative law punishable by fine. Support in the purchase or operation of the bus, e.g. tax relief, road tax, may also be invalidated retrospectively. This may be the case both in the country in which the vehicle is registered and in other countries in which the vehicle is operated. Danger. It is essential that work relevant to safety or work on safety-related systems be carried out at a qualified specialist workshop.
