Mazda will be showing off the newly refreshed CX-7 with the latest MZR-CD 2.2-liter diesel next month at the Frankfurt Motor Show. This will be the first Japanese brand diesel to feature an selective catalytic reduction system. Like other SCR systems, this one uses urea injection to convert NOx emissions to nitrogen and water. The AdBlue (aqueous urea solution) is stored in a tank under the rear cargo area and injected into the exhaust stream ahead of the catalytic converter.

The urea tank is sized to support service intervals of about 12,000 miles so the drive shouldn’t run out of urea before regular service intervals. The CX-7 will conform to EURO-V emissions standards Unfortunately, the diesel will only be offered in the European market.
