Another day passes and more news reaches us here at TheGreenCarWebsite.co.uk about a planned debut at the 63rd Frankfurt Motor Show.
This time it is the turn of the Mazda Motor Corporation, which will exhibit freshened versions of the CX-7 at the event including a version powered by the company’s MZR-CD 2.2 litre diesel engine mated to a selective catalytic reduction (SCR) system.
These systems allow for substantial reductions in nitrogen oxide emissions which will help the diesel to meet Euro 5 emission regulations. The 2.2 litre turbo diesel engine produces low volumes of nitrogen oxides which allows the SCR system to do less in post processing. The SCR sprays AdBlue aqueous urea into the exhaust flow in front of the catalytic converter, helping to convert around 40 per cent of the nitrogen oxides into nitrogen.
The vehicle also benefits from reduced size and weight of the system components, with an AdBlue storage tank fitted under the luggage area. Despite this the CX-7 offers the same 455 litres of luggage space as the petrol models. The system has also been designed to minimise consumption of AdBlue and enables the CX-7 to run for 12,427 miles between refills under normal driving conditions.
The Frankfurt Motor Show will be held from 15-27 September with the diesel CX-7 to make its debut in Europe in October 2009, with Australian sales following in November.
