Mazdas SCR system purifies vehicle exhaust gases by spraying AdBlue®*2 aqueous urea directly into the exhaust flow in front of the catalytic converter. Through a chemical reaction, the urea converts approximately 40 percent*3 of nitrous oxides into harmless nitrogen. Previously, the large size of SCR systems limited their use to trucks and buses. By reducing the size and weight of the system components, which include an AdBlue® storage tank fitted under the luggage area, Mazda is the first Japanese automaker to successfully equip a passenger vehicle with an SCR system. Even with the added components, the diesel powered CX-7 offers the same 455 liters of luggage space (VDA approved*4) as gasoline engine models. Additionally, Mazdas SCR system was designed to minimize consumption of AdBlue®, enabling the clean diesel CX-7 to run for 20,000 kilometers between refills under normal driving conditions.
