Advantages of the SCR technology over the EGR

1. The SCR system does not affect the frequency and the cost of services, unlike the EGR system that has additional maintenance costs. More frequent oil and filters changing whilst the oil required for the EGR technology is of high quality which means high price compared to the SCR technology.
2. Reduced fuel consumption. A vehicle with the SCR system and fuel discharge EURO 4 has a 2-3% less than an equivalent vehicle of EURO 3 specifications and 4-8% compared to the EGRn system.
3. The SCR system allows the engine to work free without choke setting unlike the EGR and the engine is not in danger of damages due to the circulation of cold fumes, a fact very likely to happen in the EGR system.
4. The transform into EURO 2 is manageable in case someone wants to sell it as a used vehicle.
