2008 Mercedes R 320 BlueTEC, ML 320 and GL 320 BlueTEC

In October 2006, was the first manufacturer to commence a initiative in the passenger car segment was timed to coincide with the of low-sulphur fuel in the United of America. The E 320 BlueTEC proved a success from the outset, and was World Green Car of the Year As a next step, Mercedes-Benz is now due to the R, ML and GL 320 BlueTEC in the USA, the world’s three diesel cars not only meet the particularly criteria of the American Bin 5 standard, but have the potential to fulfil the EU6 standard due in the future – and therefore considerably better all the worldwide exhaust emission for diesel passenger cars.

The V6 diesel engine powering the new models in the GL, M and R-Class shows a low fuel consumption and very low are also possible for large It has an output of 155 kW/211 hp and develops a of 540 Nm. Fuel economy is outstanding: the GL 320 for example, consumes just 9.5 of diesel fuel per 100 kilometres (25

This represents an advantage of 20 to 40 percent versus a comparable model, and easily makes the GL 320 BlueTEC the most economical SUV in the USA.

With attributes as excellent pulling power, and a high output, the diesel has also proved an attractive to the spark-ignition engine in the USA in times of fuel prices and growing to the issue of CO2 emissions. In the land of minivans, pickups and SUVs, and the driving conditions characterised by cruising speeds on the highways and overland distances, the diesel is to show its advantages particularly

At the same time, American sets very strict standards for diesel-powered vehicles. is why Mercedes-Benz introduced the E 320 BlueTEC its in-house BlueTEC technology in first, and is now including a variant of BlueTEC technology with injection in its cross-Atlantic range. innovative drive technology these large and powerful to meet the limits imposed by the US Bin 5

Impressive power, great economy and extremely low emissions

features of the six-cylinder diesel had to be modified for use in the new models ML 320 BlueTEC, GL 320 and R 320 BlueTEC with AdBlue The piston crowns were for an improved mixture formation, and the ratio was reduced from to 16.5. The VNT turbocharger and engine unit were also and reconfigured.

All three of the new SUVs are only with the 7G-TRONIC automatic transmission.

Nitrogen drastically reduced with

As a modular concept for an effective in the fuel consumption and emissions of vehicles, the BlueTEC technology by Mercedes-Benz puts in place a of coordinated measures which minimise untreated emissions in-engine features and ensure exhaust gas aftertreatment. All relevant components are successively and concertedly to a minimum, in part by using an catalytic converter and a particulate The most important goal is to a drastic reduction in nitrogen emissions, the only exhaust gas which has inherently higher in diesel engines than in engines.

Mercedes-Benz has developed two to this end. In the E 320 BlueTEC available in the USA and the E 300 BlueTEC sold in an oxidising catalytic converter and a filter are combined with a durable NOx storage-type catalytic and a special SCR (Selective Catalytic converter. The second BlueTEC is used for the new GL 320 BlueTEC, ML 320 BlueTEC and R 320 models.

In this case AdBlue, an urea solution is injected the stream of exhaust gases. releases ammonia, of which 80 is reduced to form harmless and water by the downstream SCR converter.

innovative emissions control follows the following stages:

of the engines and their combustion to reduce untreated emissions as far as These measures include engine management, four-valve third-generation common-rail direct with piezo-electric injectors, a with variable turbine and exhaust gas recirculation.

Oxidising converters are used to minimise of carbon monoxide (CO) and hydrocarbons (HC).

A particulate which has been standard in all Mercedes-Benz diesel models in countries since summer reduces particulate emissions to a measurable level. This meets both the current EU4 limits (0.025 grams/kilometre) and the US limits.

Nitrogen oxides are by a storage-type NOx catalytic converter with an SCR catalytic converter, or by injection combined with an converter. These effective methods allow the nitrogen emissions of BlueTEC vehicles to be by up to 80 percent.

AdBlue injection advantageous in large vehicles

a storage-type NOx catalytic converter or injection is used depends on the vehicle concept and the prevailing conditions from case to AdBlue technology has advantages for saloons, pickups and SUVs, as the does not need to operate an intermittent, rich combustion to clean the storage-type NOx catalytic which removes the harmful oxides from the exhaust This would be necessary at intervals in the case of heavy with relatively high consumption, and would lead to an higher consumption.

In the case of the urea-SCR process, the agent AdBlue is injected the exhaust tract. This is an urea solution which is in an auxiliary tank. When into the hot, pre-treated gases, AdBlue is first down into its constituents of and urea.

From around 170 Celsius the urea is converted ammonia (NH3) – the active agent in this The ammonia is stored in the catalytic and reduces the nitrogen oxides harmless nitrogen when gases containing nitrogen flow through the catalytic The engine management system the injection of AdBlue in such a way the ammonia reservoir of the SCR converter contains some but never too ammonia.

This is monitored by an NOx

A small AdBlue tank is

The urea solution is held in a onboard tank, and fed to the metering by means of a pump. As the average of AdBlue is only around 0.1 per 100 kilometres (or 1 to 3 percent of diesel the tank can be of such a size it only needs to be refilled at the during regular service The tank capacity is 28 litres in the R 320 and ML 320 BlueTEC, and 32 litres in the GL 320 BlueTEC.

More extensive equipment and modifications

The R-Class excels with its outstanding comfort, and with the most and variable interior with up to seats.

The M-Class is the most Mercedes-Benz Sport Utility and is seen as the trailblazer for all modern SUVs. And with the GL-Class, occupies the peak position in the SUV world – its occupants first-class on-road and off-road under all conditions.

All three have now been revised in respects. The modifications

to the M-Class are the comprehensive of all. The new generation of dynamic SUV now has even more characteristics, and appears even sporty and powerful. The front and ends have been and given a stylistically updated and touch. The front end of this is now defined by a redesigned bumper, headlamps and a larger, even dominant radiator.

The rear also has a redesigned bumper inset reflective strips to the vehicle width, as well as lights with smoked-glass Stylistic fine-tuning and new materials are pleasing to the eye and touch combine a new two-tone colour scheme to add highlights to the interior. One eye-catching is the new four-spoke multifunction steering which the GL and R-Class will receive.

The standard appointments for the M, R and have also been expanded. They now include the preventive occupant protection PRE-SAFE® and NECK-PRO head as well as a new, Mercedes-Benz telematic system with improved user friendliness, performance and numerous additional

Mercedes-Benz is the trendsetter for diesel

As long as 70 years ago, was the first manufacturer to use the combustion pioneered by Rudolf Diesel in a car engine. This technology has a higher efficiency than the engine, and has been steadily over many years. One technological leap forward led to the of the modern diesel in 1997: the of common-rail direct injection in with four-valve technology.

Sin ce the abbreviation CDI has stood for both fuel economy and an enormous in torque – a synonym for a of pulling power which plenty of driving pleasure and makes diesels superior to models developing the same

If the diesel has previously had any disadvantages the petrol engine, this has in the area of its specific emissions above all soot particles and oxides. Ever since the of the maintenance-free particulate filter in 2003, Mercedes-Benz has however set the best example where are concerned.

And despite having a reduction in nitrogen oxides by 75 percent thanks to in-engine over the last 15 years, has not been content to rest on its in this respect. Equipped innovative BlueTEC technology, was introduced for the first time in a car in the USA, the high-tech diesel from Mercedes-Benz meet the toughest exhaust emission While AdBlue injection the new M 320 BlueTEC, R 320 BlueTEC and GL 320 BlueTEC the cleanest diesel SUVs.
