BlueTec for commercial vehicles and for passenger cars

The introduction of in the passenger car in 2006 marks the of a new era in Mercedes-Benz diesel-powered cars. The of the Stuttgart-based brand initially this visionary emission system for commercial vehicles, it to the market in 2005. BlueTec (it is differently if referring to cars or vehicles) immediately set standards for the of the pollutants in diesel exhaust which promptly was reflected in on the market: in February 2006 the BlueTec truck with 5 engine was delivered to a customer. And in more than 160,000 with BlueTec were in – with a great many to come. This is a good for developing BlueTEC for diesel cars.

Evolution of the compression-ignition in the car

Considering the history of innovation of the passenger car at Mercedes-Benz, the step to BlueTEC into present-day is only logical: the Stuttgart built the first diesel car in 1936. 1971 saw the one-millionth car compression-ignition engine since the World War roll off the assembly And in 1976 the C 111-II with engine set standards on its record-breaking run in The history of diesel technology is again and again by such innovations – especially owing to the of Mercedes-Benz. Since about the pace of technological development has up very strongly. And this is why in BlueTEC became the latest of this diesel evolution.

the development of the compression-ignition engine a clean and powerful drive for automobiles can take us is shown by like the S-Class S 320 BlueTEC presented at the Frankfurt International Show in 2005, which the low-emission diesel with an motor. With an electric integrated in the powertrain, the concept car was a hybrid”, with significantly fuel consumption especially in stop-and-go traffic. The diesel switches itself off whenever it is not All the modifications and features combined the fuel consumption of the BlueTEC by some 20 percent versus the predecessor model. The combined of this S-Class car is 179 kW (243 the combined torque is as high as 575 metres. The car accelerates from to 100 km/h in 7.2 seconds, and its top sped is limited to 250 km/h. Fuel (New European Driving is as low as 7.7 litres per 100 kilometres. The study this very clear: at the diesel has great potential as a drive of the future. And this already was within close for a few years later BlueTEC cars were being in series.

But for the first, in 2006 the Mercedes-Benz BlueTec commercial were the trendsetters for the car sector, as the innovative system for reducing oxides (NOX) and other also lends itself to in passenger cars: BlueTEC nitrogen oxides to such an that the toughest emission worldwide can be met.

In early Mercedes-Benz then presented for passenger cars as a ready-for-production consisting of several components. The optimisation of the engines and the combustion taking place inside constitutes the basis of this With solutions like injection nozzles, the use of the latest of CDI technology and other measures, the raw are cut to an extremely low level. This is the emission control system an oxidising catalytic converter hydrocarbons and carbon monoxide) and a filter comes in. The final is nitrogen oxide reduction by the component proper.

2006 – E 320 the future of the diesel car

It’s the cleanest diesel: in late the E 320 BlueTEC hit the US market as the first BlueTEC car. The E 320 BlueTEC is an model which is based on the E 320 CDI V6 and relies on the BlueTEC technology by Mercedes-Benz. BlueTEC is the designation for a efficient method of minimizing oxide emissions already in commercial vehicles. In contrast to vehicles, the E 320 CDI BlueTEC does not use of AdBlue injection but reduces oxides with a system on an improved storage-type catalytic

Three E 320 BlueTEC vehicles took part in the 13,600 “E-Class Experience Paris – from October to November This long-distance trip a total of 36 Mercedes-Benz E-Class recalled an adventurous long-distance organised in 1907, but which in the opposite direction, from to Paris. Despite this event in the important automotive China, the E 320 BlueTEC was first put on the in the United States.

The question may why the E 320 BlueTEC made its debut in the One reason, of course, is the growing for economical and at the same time cars in that country, by rising fuel prices. But yet another reason for this timing: “The introduction of diesel fuel in the USA is something we been fighting for alongside for a long time, and an opportunity we to use from Day One,” said Dr Weber, member of the Board of of Daimler AG responsible for Research, the car was introduced in Las Vegas, Nevada. diesel-engined cars which, in Europe, account for more half of new registrations annually, unable to develop their potential in the USA due to the excessively high content in the fuel until This changed at the end of 2006 to the nation-wide introduction of clean fuel with a sulphur of just 15 ppm (15 cubic centimetres of per cubic metre of fuel). The Ultra Low Sulfur Diesel would be available at up to 76,000 stations in the USA in a first step and permit the use of BlueTEC. With innovative diesel technology, is also able to remain the strictest globally applicable where nitrogen oxide are concerned. Hence, all the preconditions for the of modern diesel technology in the USA are

2007 – BlueTEC for passenger comes to Europe

Encouraged by the of the E 320 BlueTEC developed for the North market, Mercedes-Benz decided to the E 300 BlueTEC of the 211 series as first car with BlueTEC for the European at the end of the year 2007. It easily is the diesel in its class and fully the requirements of the Euro 5 exhaust standards.

2007 – BlueTEC in and concept cars

Mercedes-Benz the direction in which developments in the car sector are going with vehicles in 2006, first and the Vision GL 320 BlueTEC and the Vision CLS 320 The GL has an SCR catalytic converter with injection; the CLS, like the features an improved nitrogen-oxide catalytic converter.

The Vision GL 420 presented in 2007 then that great fuel and extremely low emissions can be achieved BlueTEC – also, and in particular, in and powerful cars. The high-performance V8 engine develops 216 kW (290 has a torque of 700 Newton metres and is to have a fuel consumption of 9.8 litres per 100 kilometres. The car’s styling expresses the special of the GL 420 BlueTEC and at the same time the wishes of Mercedes-Benz customers in the USA for greater exclusiveness and individualisation. The distinctively swept-back front end its dominant radiator grille the extraordinary performance of the V8 diesel in the car’s appearance and gives the car a forward thrust even it’s stationary. These looks are enhanced by flared arches, representative 21-inch and lateral floorboards.

2007 – Systematic expansion of the model line-up

At the North International Auto Show in Detroit in January 2007, displayed three new BlueTEC with SCR exhaust gas aftertreatment it built in series beginning in On this occasion, Dr. Thomas had this to say: “With our clean and efficient diesel comply with the stringent Bin 5 norm. This also to the three new V6 BlueTEC models R 320 ML 320 BlueTEC and GL 320 BlueTEC which we launch into the US market in

In the brand’s systematic expansion of its model line-up, Mercedes-Benz was up by a J. D. Power study in 2007: Outlook for Diesel” predicts a of diesel-engined cars in new registrations of over 15 percent in North by 2015. The precursor is the E 320 BlueTEC is already available in the market. 35 miles per gallon or 6.7 litres per 100 it is by far the most economical car in its class in the States.

Awards for BlueTEC

The to BlueTEC in the USA is extremely positive, as by the distinctions awarded by renowned science and engineering journals for the technology developed by Mercedes-Benz at the end of Scientific American named as one of the 50 groundbreaking innovations in science and of the year 2006. Popular the oldest and best-known scientific included BlueTEC in “Best of New”, its list of the year’s product innovations. Ward’s Group, a leading publisher of media and trade journals for the industry, nominated the engine of the E 320 for its listing of the ten best drive of the year 2007.

In 2007, editors from 22 countries the E 320 BlueTEC as the “World Green Car at the International Auto Show. award recognises the role of as pacemaker of a novel diesel which makes the compression-ignition as clean as a petrol engine.

catalytic converter or AdBlue

The diesel principle has come a way from Rudolf Diesel’s to the modular BlueTEC system. and again the company contributed innovations to develop the diesel to its present level. Thus, the engine presents itself as a high-performing and economical high-tech with the potential for meeting the toughest international emission in the future. Not only the powerful power plants were to from this, but the state-of-the-art diesel engines from as well.

Four-cylinder engine BlueTEC

So at the Geneva Motor in February 2007, Mercedes-Benz for the time presented the environmentally BlueTEC emission control in combination with a four-cylinder with optimised fuel The Vision C 220 BlueTEC outlines the to compliance with the further Euro 6 emission norm will come into for all new vehicles throughout Europe in At an output of 125 kW (170 hp) and a maximum of 400 Newton metres, the Vision C 220 consumes 5.5 litres of diesel per 100 This is the result of ongoing of diesel engine technology and energy management.

Dr. Dieter Chairman of the Board of Management of AG and Head of Mercedes-Benz Cars, on this new development as follows: modern four-cylinder diesel with BlueTEC emission is a prime example of cutting-edge with a safe future. our diesel strategy, we provide the to the question of how fuel consumption – and carbon dioxide emissions – can be how all exhaust gas constituents including oxides can be further reduced, and motoring pleasure can be ensured at the time. We are convinced that the diesel currently represents the and most efficient solution in respect.”

With the Vision C 220 BlueTEC, outlines the next steps in the initiative in very concrete – an initiative the company launched in the USA in 2006. The Vision C 220 BlueTEC forthcoming emission limits – the significantly tightened Euro 6 which will apply to all new from 1 September 2015. To an idea of the reductions required, are a few figures: compared with the applicable limit values, emissions have to be reduced by a of five for compliance with the 5 limits which will into force on 1 January And according to Euro 6, the nitrogen limit will be just 30 of the limits applicable in 2007. All diesel cars with particulate filters already in 2007 with the particulate to be introduced in 2011.

TrueBlueSolutions: shows the future of the clean drive system in 2007

At the International Motor Show in am Main, Mercedes-Benz displayed an fleet of especially economical and automobiles with intelligently drive technologies – studies as as production vehicles. They eight BlueTEC models and hybrid vehicles. The motto of the presentation was “TrueBlueSolutions”, showing drive solutions for the future of the

For instance, the S 300 BlueTEC HYBRID as of a production model for the near featured a unique combination of and hybrid technology, offering a output of 165 kW (224 hp) and maximum torque of 560 Newton metres, with the figures for a big-displacement V8.

Also on display at the Mercedes-Benz the new E 300 BlueTEC for the European market and the 320 models of the R, ML and GL-Class. In addition, a of the near-series studies C 250 BlueTEC, the new generation of the Mercedes-Benz four-cylinder engine, and E 300 BlueTEC HYBRID be seen.

Mission: Sustainable

Sustainable mobility has been a mission pursued by Daimler AG for The company is working on low-emission and more economical vehicle with great commitment. The is on reducing not only carbon but also all other pollutants have to be taken into on the road to sustainable mobility. The of these ongoing efforts are from 1995 through the carbon dioxide emissions of vehicles have declined by 20 percent, and this rate is higher than the 14 percent achieved by the European motor on average. It should also be that no other motor can beat this rate.

A of technical innovations was required to this reduction within the vehicle fleet. An impressive of this is BlueTEC technology for engines. Shortly after its in the passenger car it was already helping to the Mercedes-Benz models the most and cleanest diesel-engined vehicles in respective categories.

Since these innovations also BlueEFFICIENCY, the comprehensive vehicle consumption reduction programme. The engine in the CDI BlueEFFICIENCY models from this innovative for BlueEFFICIENCY the Mercedes-Benz engineers use of the potential in all areas of development in to reduce weight, wind and rolling resistance further and energy management in vehicles more efficiently.

Thomas member of the Board of Management of AG and responsible for Group Research and Cars Development commented on in the summer of 2009: “Mercedes-Benz car are very economical and clean as it today. Our BlueEFFICIENCY models – we have 58 of them on the market by the end of the – are a good example. Just how this concept is is shown by the new which combines ultramodern and the world’s best Cd figure in vehicle category with pinpoint measures intended to the vehicles, including lightweight and intelligent energy management. In the sum of efforts we attain 23 percent efficiency compared with the model.”

BlueTEC and the future: a Mercedes-Benz story

The Mercedes-Benz diesel car success story has gained new owing to BlueTEC – not only in the American market. For as of September Mercedes-Benz has been offering now complete BlueTEC model also in Europe: along the new W 212 series E-Class Saloon E 350 the ML 350 BlueTEC 4MATIC, GL 350 BlueTEC and R 350 BlueTEC 4MATIC, which had been on sale in the USA for a year. The BlueTEC technology lends SUVs additional attractiveness in In spring 2010 the G 350 BlueTEC And so a genuine classic – the G-Class, a since 1979 – meets the clean 21st century diesel drive.

The new E 350 BlueTEC a V6 diesel engine which 155 kW (211 hp) and makes maximum of 540 Newton metres available 1600 rpm. The fuel of this model, fitted a seven-speed automatic transmission, is 7.0 per 100 kilometres (combined NEDC For the BlueTEC model the V6 engine was in detail, among other in order to reduce the in-engine raw and meet the legal requirements in to on-board diagnosis (OBD). The control system has a close-coupled catalytic converter and a diesel filter positioned in the area of the – this shortens the regeneration

The heart of the BlueTEC system is two SCR Catalytic Reduction) catalytic with an upstream AdBlue® Monitoring and diagnosis of the complex gas aftertreatment are handled by several including a differential pressure oxygen sensor and NOX and temperature For the service fluid AdBlue® the E 350 gets an additional 25-litre fitted with a diaphragm valve, pressure and temperature as well as electric heating. It the 33-percent urea solution freezing at low temperatures. Refilling of the should take place regular maintenance service. to this complex technology the emissions of the E 350 BlueTEC are at EU6 level.

But the of Mercedes-Benz to make the diesel cleaner with BlueTEC are not to six-cylinder models: with the E 250 study, specifically designed for the American market, in spring Mercedes-Benz showed a way to combine the technology of the E-Class with a with optimised fuel In the study the Mercedes-Benz combined the four-cylinder diesel with The result is the most economical and diesel model in this category which, with its of as much as 44 miles per gallon to 5.3 litres per 100 kilometres), attains a efficiency better than of most hybrid vehicles in the US Thanks to highly effective control, the E 250 BlueTEC does than required by the American and ULEV emission standards, are among the toughest in the world. At the time, thanks to its high of 500 Newton metres, seven-speed transmission and Lanchester balancer the refinement and performance of the four-cylinder is on a with that of six-cylinders.

as much as new engines, the BlueEFFICIENCY of the W 212 E-Class also conduces to the reduction in the fuel consumption of the models, as demonstrated by the new four-cylinder engine in the E 250 CDI BlueEFFICIENCY. With an of 150 kW (204 hp) and 500 Newton metres of from 2.1 litres displacement it seven percent more and 25 percent more torque the current V6 diesel engine in the E 280 CDI its displacement of three litres. At the time it uses about 23 less fuel. With 5.3 per 100 kilometres (combined NEDC it is distinctly more economical comparable saloons in this class. The CO2 emissions of the new four-cylinder models come to 139 grams per or up to 24 percent below the figures for the CDI

Mercedes-Benz GL420 GDI

Engineers from all Development have optimised parts and to save fuel through weight, new design, improved or efficient energy management. The in the wind tunnel was highly With a drag coefficient of the new E-Class is the most aerodynamically executive-class saloon in the world. It the previous model’s very Cd by another four percent. The are improved, for example, by an automatically fan louvre which regulates the of air in the engine compartment on demand.

BlueEFFICIENCY measures included developed tyres with up to 17 less rolling resistance and the control of alternator, fuel air conditioner compressor and power

E-Class with new four-cylinder engines

With the new generation of diesel power plants in Mercedes-Benz introduced the fourth of its tried-and-trusted common-rail direct-injection into series production. One of its is a 400-bar increase in the maximum pressure, which now stands at bar in the 220 CDI BlueEFFICIENCY and the E 250 CDI BlueEFFICIENCY. This pressure potential is essential for engine output up to 150 kW (204 hp) and torque to 500 Newton metres, distinctly reducing untreated

Newly developed piezo are key components in the latest CDI engine They use piezo-ceramic properties to their crystal structure – and their thickness – in a matter of when electrical voltage is The new injectors are equipped with a of thin piezo-ceramic layers the “piezo stack”) to enable to achieve a sufficient overall from the very small per layer. In contrast to the systems used to date, this activates the nozzle needle so that the fuel injection can be even more precisely in with the current load and situation – for example by means of multiple injections, which a favourable effect on emissions, consumption and combustion noise. the engine runs much at idle than its predecessor. to peak output and to full-load (with respect to emissions) is the ignition pressure – at 200 bar the new four-cylinder from Mercedes-Benz is tops in the car diesel engine sector.

In the new engines for the E 220 CDI BlueEFFICIENCY and E 250 CDI BlueEFFICIENCY, also realises two-stage with demand-related control, for the time in production passenger car engines. The major advantage of sophisticated technology is improved charging, and therefore high even at low engine speeds. consumption is also reduced. the car is driven, this concept itself felt by harmonious characteristics with no turbo a favourable torque curve the entire engine speed great responsiveness and noticeably performance.

But depending on application techniques also find for example in the E 200 CDI BlueEFFICIENCY, which a single-stage variable-nozzle turbocharger. the engine output is smaller, a turbocharger could be chosen to very good drive-away

Other special features of the new diesel engines include exhaust gas recirculation for NOX reduction, a camshaft drive and the controllable pump.

Dieter Zetsche, of the Board of Management of Daimler AG and of Mercedes-Benz Cars, made an favourable review of BlueEFFICIENCY in 2010, citing the current CDI models of the E-Class as example: “We significantly reduced consumption and with our BlueEFFICIENCY offensive. Our new boast an excellent ratio of to CO2 emissions, thereby achieving an degree of efficiency.”

BlueTEC goes into production

The of the E 300 BlueTEC HYBRID, the first diesel hybrid passenger car Mercedes-Benz, at the International Motor in Geneva in 2010 marks a new stage in the development of the diesel in Mercedes-Benz cars. The E 300 BlueTEC pairs a 2.2-litre four-cylinder engine developing 150 kW (204 hp) a powerful hybrid module. Its 15 kW motor, positioned between the combustion engine and the 7-speed transmission, assists the diesel when the car is accelerating (boost although it is also suitable for using electric power It is also used for the recuperation of energy in alternator mode.

The E 300 BlueTEC HYBRID consumes 4.1 of diesel fuel per 100 kilometres 109 grams per kilometre). The diesel will be launched as Saloon and at the end of 2011.

BlueTEC and CDI BlueEFFICIENCY in the

In summer 2010 Mercedes-Benz the first BlueTEC model of the in its range, the S 350 BlueTEC. With fuel consumption of just 6.8 of diesel per 100 kilometres (NEDC) – to CO2 emissions of 177 grams per kilometre – the new model is eleven percent economical than its predecessor. At the time, the power output is up ten at 190 kW (258 hp) and torque is 15 percent at 620 Newton metres. The S 350 BlueTEC complies with the emission which are planned for 2014 the introduction of the EU6 standard.

The new S-Class model already features Blind Spot Assist and Lane Keeping Assist, the for active safety. The S 350 BlueTEC combines outstanding safety and comfort with the effortlessly performance of an eight-cylinder vehicle and boasts very good consumption and emission values.

In 2010 the S 250 CDI BlueEFFICIENCY then somewhat of a sensation: this Saloon is the first 5-litre car in the class and the first model a four-cylinder in the more than success story of the S-Class. The efficient turbodiesel achieves consumption of only 5.7 litres per 100 in the NEDC cycle, which to CO2 emissions of 149 grams per kilometre. makes the new S 250 CDI BlueEFFICIENCY the first in its class to undercut the 150 gram for CO2 emissions.

To ensure hallmark comfort, dynamically controlled mounts feature as an innovation in the new S 250 CDI The rigidity and damping of these which are interlinked with the management system via databus, according to engine speed, and vehicle speed, thus the transmission of unwanted vibrations and from the engine to the body.

an eye to the 125th anniversary of the invention of the by Carl Benz in 1886, Zetsche, Chairman of the Board of of Daimler AG and Head of Mercedes-Benz referred to the S 250 CDI BlueEFFICIENCY as a component of the future of the automobile in September “The invention created by and Benz changed the world and virtually every aspect of life. Now we are inventing the automobile for the time, and the effects will be revolutionary.”
