Below are questions relating to maintenance and service of engines which use SCR, EGR and DPF systems to comply with Stage IIIB:
This type of engine needs a change of the SCR system filter every 1000 operating hours.
On average, the engine consumes 5 to 7% of AdBlue® in relation to fuel consumption. Actual consumption, however, is highly dependent on working conditions.
The system gives a warning if the level of AdBlue® in the AdBlue® tank is too low. According to legislation, it is not allowed to run the machine without Adblue®, as the engine would not be able to meet the emissions regulations. If the tank is empty, the engine torque is reduced.
SCR technology is used in On-highway trucks since 2007. The AdBlue® additive can be found locally and is typically available at service stations. The website “www.FindAdBlue.com” provides information where it is sold throughout Europe.
The engine oil must fulfill the following quality requirements: ACEA E3, E4, E5 or E7 (E7 requires fuel with a low sulphur content). For engines not running on low-sulphur fuel, the TBN (Total Base Number) should be at least 12 (ASTM 2896).
There is no change in life expectancy of Stage IIIB engines.
