Is BlueTEC Diesel?

Mercedes-Benz uses the brand BlueTEC to describe their diesel engine exhaust treatment technology. The business built and produced two versions of this system to keep up with the constantly growing and increasingly rigorous emissions rules of North America and Europe. The 2007 E320 BlueTEC sedan was the first version to be released in the United States, and it was designed to use the then-new Ultra Low Sulfur Diesel (ULSD). Mercedes-Benz then produced the R, ML, and GL 320 series BlueTEC diesels with AdBlue injection, which meet America’s stringent BIN 5 emissions regulations and are on course to reach Europe’s EU6 specifications.

Are all BlueTEC diesel?

All Mercedes-Benz diesel engines produced after the 2009 model year will be part of the BlueTEC engine series. The series was established in reaction to the EPA’s 2006 mandate of tighter diesel emissions limits. To promote efficient combustion of the newly standardized Ultra-Low Sulfur Diesel, improved emissions control systems were required on all diesel cars made during or after the 2007 model year as part of these requirements.

The term “BlueTEC” refers to the combination of two distinct emissions-reduction technologies. Both technologies aim to reduce the amount of nitrogen oxide discharged into the atmosphere considerably. The first method, known as AdBlue, involves injecting urea into nitrogen oxide to chemically transform it into harmless water vapor and nitrogen. The second technology, named DeNOX, combines an oxidizing catalytic converter, particulate filter, and peripheral systems to reduce nitrogen oxide and soot emissions from Mercedes-Benz diesel vehicles even more.

What is a BlueTEC diesel engine?

Engines equipped with improved NOx reduction technology for vehicle emissions control in diesel-powered vehicles are marketed as BlueTEC by Daimler AG. A selective catalytic reduction (SCR) system that uses diesel exhaust fluid is included in BlueTec vehicles, as is a NOx adsorber system called DeNOx, which combines an oxidizing catalytic converter and diesel particle filter with other NOx decreasing systems.

Private plaintiffs sued Mercedes-Benz, Daimler AG, Bosch LLC, and Bosch GmbH in February 2016, saying that BlueTec violates regulations in a similar way to the Volkswagen emissions crisis.

U.S. District Judge Jose L. Linares dismissed the complaint without prejudice on December 6, 2016, ruling that the plaintiffs lacked standing.

After Plaintiffs modified their lawsuit, the case was revived, and the matter is still pending.

What is Mercedes BlueTEC?

Mercedes-Benz BlueTEC diesel technology improves performance and fuel efficiency while simultaneously lowering pollutants from diesel engines. AdBlue is a liquid solution that is pumped into the exhaust to convert nitrogen oxide emissions to nitrogen and oxygen, which are environmentally friendly.

Is the Mercedes BlueTEC diesel a good engine?

Mercedes-Benz automobiles, SUVs, and Sprinter vans with BlueTEC engines are among the world’s most advanced diesel engines. Variable geometry turbochargers and a high-pressure fuel injection system provide optimal combustion.

This improves power output while also lowering exhaust gas emissions. Because the soot is contained by the diesel particle filter, clouds of black smoke on acceleration are no longer an issue (DPF). Furthermore, diesel exhaust fluid (DEF) is pumped into the exhaust gas stream. NOx emissions are reduced as a result.

This is how Mercedes was able to maintain high engine power outputs and fuel economy while meeting the strictest emission rules. All of these advanced technologies, on the other hand, have the potential to fail. It’s crucial to be aware of the most common flaws.

Many Mercedes-Benz diesel vehicles, including the E350, ML350, GL350, R350, Sprinter, R320 CDI, and BlueTec, have common faults.

Which Mercedes-Benz is diesel?

Mercedes-Benz BlueTEC engines are currently offered in the E-Class, GL-Class, GLK-Class, and M-Class models. Expect more Mercedes-Benz BlueTEC automobiles in the future as diesel-powered vehicles become more popular.

Is BlueTEC diesel clean?

A Mercedes-Benz BlueTEC engine’s revolutionary invention begins with enhanced combustion, which results in more efficient fuel use. As a result of the huge reduction in soot and pollutants, BlueTEC is now one of the cleanest diesel engines in the world.

Is BlueEFFICIENCY the same as BlueTEC?

Because the concept of BlueEFFICIENCY has been around for so long, many secondhand vehicles are already fitted with it. The C180 Kompressor, C200 CDI, and C350 CGI were all given a makeover when the technology was initially introduced. The C200 CDI gets the full treatment, including all of the above improvements as well as a 2.2-liter engine capable of 55.4 mpg. These advancements allowed owners of these automobiles to avoid paying higher road tax bands, particularly in the United Kingdom.

Why BlueEFFICIENCY Is Better Than Other Manufacturer’s Technology

VW’s BlueMotion and BMW’s Dynamic Efficiency are similar to BlueEFFICIENCY. All three are umbrella brands that inform clients that the vehicle they are purchasing has the best fuel economy and lowest CO2 emissions in its class.

However, there are several aspects of BlueEFFICIENCY that make it marginally superior to its competitors’ solutions.

Take, for example, BlueMotion. VW experimented with aerodynamic efficiency by making their vehicles’ gear ratios longer. They didn’t, however, go to the same engine management lengths as Mercedes engineers, experimenting with practically all of their vehicle’s subsystems in search of energy savings. Similarly, while BMW implemented a slew of innovations to boost efficiency solely through technology, it couldn’t match Mercedes’ stunning 23% increase. Instead, it made its most ambitious efficiency claims by altering the driving style of its drivers.

What Is The Difference Between Mercedes BlueEFFICIENCY Vs BlueTEC?

Consumers are meant to be able to distinguish between different products and technology by using branding names. Consumers, on the other hand, have been perplexed about the distinction between BlueEFFICIENCY and BlueTEC since the beginning.

Mercedes’ marketing moniker for engines with improved NOx-reduction technologies is BlueTEC. To reduce pollution, vehicles equipped with the technology combine nitrogen oxide absorbers, selective catalytic converters, and diesel particulate filters.

Mercedes-Benz first installed the new system in its E-Class and GL-Class sedans in 2006, the same year VW unveiled the first real BlueMotion Polo. The technology helped Mercedes make Ward’s Ten Best Engines list in 2007 and 2008.

Surprisingly, Mercedes introduced the technology in response to modern diesel engines’ increased efficiency. When the corporation switched from the Otto Cycle to the Diesel Cycle, the higher-temperature air-fuel combinations produced greater NOx, exceeding regulatory limitations in some situations. As a result, the new technology was developed in response to the requirement to manufacture more efficient engines while simultaneously reducing pollutants.

BlueTEC’s operation is complicated and comprises several processes. Here’s how it goes:

  • Hydrocarbons and carbon monoxide exiting the engine react with diesel oxidation catalysts, converting them to less harmful secondary chemicals.
  • Particulate filters prevent soot from escaping and store it until the filter is full, at which point it is burned off.
  • The remaining NOx molecules are converted to harmless nitrogen and water by a selective catalytic converter.

As a result, BlueTEC is similar to BlueEFFICIENCY in that it is a collection of technologies. BlueTEC, on the other hand, refers to improvements that improve emissions and reduce hazardous vapors that escape the exhaust system. It does not refer to any other energy-saving or fuel-efficiency features in the car.

How often do you add BlueTEC?

AdBlue: If you’re driving one of the latest Euro6 diesel automobiles with low emissions, you’ve probably already topped up the specific tank with the additive. But, if you’ve never heard of this new chemical, what is it, why is it crucial to the health of your car, and how often should you add it to keep it in good shape? The do’s and don’ts of using AdBlue are detailed here.

New Euro6 emissions limits for diesel cars went into effect in September 2015 (a year later for vans), with the goal of reducing a variety of hazardous chemicals connected to respiratory ailments.

The new restrictions are particularly focused on nitrogen oxides (NOx), which have been reduced from 180 mg/km to merely 80 mg/km. The goal is to reduce these hazardous emissions, hence limiting the environmental and public health consequences.

Many major European cities, including London and Paris, are considering banning diesels that do not satisfy Euro6 rules at certain times and on specific days.

To fulfill the new standards, carmakers have mostly relied on a technology known as Selective Catalytic Reduction, which entails injecting a diesel exhaust fluid (DEF) into existing gas circulatory systems to aid in the breakdown of toxic NOx. AdBlue is the common name for this DEF.

Clean Air Zones, such as London’s Ultra Low Emission Zone, require diesel cars and vans to be Euro6 compliant, or a daily fee will be imposed.

AdBlue is a synthetic urea that operates by converting nitrogen oxide to steam and nitrogen, which are both safe. It’s kept in a tank like petrol, and AdBlue tanks are being installed in an increasing number of diesel vehicles, particularly those with larger engines. Certain producers, on the other hand, may simply refer to it as “Emissions Additive.”

AdBlue is not a gasoline additive that is pumped into the engine. It’s added to the car’s exhaust system’s catalyst system.

The amount of AdBlue consumed is proportional to the amount of time the engine is used. A typical car will use about 1.5 litres of AdBlue every 620 miles, according to estimates. Because AdBlue tanks come in a variety of sizes, when you need to refuel is determined by your driving style, the amount of miles you drive, and the size of the tank. When it’s time to refuel, a dashboard warning light will illuminate.

AdBlue has been widely used on trucks and buses since 2006, when Euro4 rules were implemented for those vehicle classes.

AdBlue is seen as a consumable, analogous to gasoline. As a result, it is the driver’s responsibility to keep the AdBlue tank topped off and to pay any associated charges. AdBlue should never be used as a gasoline additive. AdBlue is kept in a separate tank at all times. In many vehicles, however, the AdBlue filler will be close to the fuel filler.

Any damage done as a result of AdBlue misuse, such as adding it to either petrol or diesel tanks, or a breakdown caused by low AdBlue levels, will not be covered under maintenance or recovery agreements.

AdBlue expenditures are not covered by maintained lease contracts. Certain leasing providers, on the other hand, will top up AdBlue as part of a standard service.

By reviewing their vehicle handbook, drivers can become more aware of their obligations.

  • AdBlue is an emissions reduction solution that complements existing DPF technology and is exclusively relevant to diesel engines.
  • A DPF-equipped diesel vehicle may or may not have an AdBlue tank. Cars with an AdBlue tank, on the other hand, always have a DPF as part of the entire emission control package.
  • The AdBlue and DPF warning lights are independent of one another and will illuminate at different times.
  • AdBlue is added to the right kind of fuel for the right kind of person. Driving style, journey type, engine and vehicle load, and environmental variables all influence usage.
  • AdBlue can be acquired at car dealers, garages, dealerships, and some gas stations, as well as online. In general, a 10 litre container of AdBlue costs roughly £12.50 at Halfords.
  • The position of the AdBlue filling varies by manufacturer and model. The boot, next to the gasoline filler, or under the hood are all common positions.
  • Because the size of the AdBlue tank installed in vehicles varies by manufacturer and model, the time between top-ups will also vary.
  • AdBlue may need to be topped up every 5,000 to 8,000 miles, according to conservative estimates, though this can vary depending on the brand, model, and driving style.
  • In rare cases, such as as part of a normal servicing, some manufacturers may give AdBlue for free. However, it’s quite improbable that refills during typical servings will be enough to keep AdBlue levels stable.
  • Variable-service vehicles demand special attention because an AdBlue top-up is almost always required before the initial service.
  • When AdBlue levels are low, the driver information system will issue a series of alerts. Audi models, for example, show a countdown from 1,500 kilometers to a required refill.
  • It is critical that these warnings are heeded as soon as possible. The automobile will continue to run on reduced power if AdBlue falls below a predetermined threshold. It will not restart once it has been stopped until enough AdBlue has been injected. You will be charged for recovery if this happens on the side of the road.
  • For example, to restart an Audi, a minimum of 5.7 litres of AdBlue is necessary, albeit this number varies between manufacturers.
  • AdBlue should never be used as a gasoline additive. If AdBlue is put through the fuel filler, the vehicle should not be started and the relevant emergency assistance number should be called immediately.
  • If you mistakenly put petrol in the AdBlue tank, the same rules apply: don’t start the car and call the appropriate emergency number right away.

What is the difference between Mercedes BlueTEC vs 4Matic?

The 3.0-liter turbodiesel V6 in the ML350 Bluetec uses clean-diesel technology that is allowed in 50 states. It generates 240 horsepower and 455 pound-feet of torque. This and all higher-trim versions come standard with 4Matic all-wheel drive. Mercedes claims it will go from zero to 60 mph in the same amount of time as the gas-powered ML350, but the fuel economy will improve to 20/28/23 mpg.

The 4.7-liter twin-turbo V8 in the ML550 delivers 402 horsepower and 443 pound-feet of torque. It will reach 60 mph in 5.3 seconds, according to Mercedes. The fuel efficiency is assessed to be 14/20/16 mpg by the EPA.

The 5.5-liter twin-turbo V8 in the ML63 AMG makes 518 horsepower and 516 pound-feet of torque. The AMG Performance option increases the engine’s output to 550 horsepower and 560 pound-feet of torque. In ordinary form, Mercedes claims the ML63 will reach 60 mph in 4.7 seconds, with the Performance package shaving a tenth of a second off that time. The fuel economy is 13/17/15 mpg.
