Sulfur Robustness Packages for Euro V and Euro VI enginesConversion of 1st generation OM 471 engines for diesel fuel with a high sulfur content

2 Sulfur Robustness Packages for Euro V and Euro VI engines

To ensure that a Mercedes-Benz truck with an OM 471 series engine also runs optimally on high-sulfur fuel

Mercedes-Benz diesel engines meet the highest requirements with respect to power, reliability and environmental compat-ibility. To ensure this, compliance with national emissions regulations during engine operation has the highest priority. For this reason Mercedes-Benz configures its diesel engines according to European standard (EN) 590. This fuel standard, which has been mandatory within the EU since January 1, 2009, defines a maximum sulfur limit of 10 mg/kg in diesel fuel. However, fuel meeting the EN 590 quality standard is not available everywhere in the world. A high sulfur content can considerably compro-mise the performance of Euro V and Euro VI engines. The worldwide sulfur contents of commercially available diesel fuels in the respective countries are classified on page 8 of this product information.

If you operate your vehicle in countries outside the EU that have higher levels of sulfur in their fuel, please carefully read and take note of the information below: Important: Mercedes-Benz diesel engines are designed for diesel fuels according to EN 590 - other fuel qualities can cause irreparable damage to the engine and the exhaust aftertreatment system, and considerably reduce their life expectancy. We therefore urgently recommend the use of low-sulfur fuel! If you are unable to obtain low-sulfur fuel, the following technical conversion packages are available. Please note that also after conversion, the relevant national emissions regulations must be adhered to when operating the vehicle.

To ensure that your Mercedes-Benz truck also delivers the best possible performance and reliability when fuel quality is poor, Mercedes-Benz recommends that you convert the vehicle with the following Sulfur Robustness Packages.

The following pages will tell you all you need to know about the conversion.

It is not merely a software update! The Sulfur Robustness Packages

The need to convert the engine arises from the possible formation of sulfuric acid in the engine system. This sulfuric acid is the product of the sulfur content in the diesel fuel and water.

Important: The sulfuric acid causes massive damage to the engine components, and considerably increases the risk of an engine breakdown.

As the high sulfur content in the fuel cannot be reduced, the ingress of water and the formation of condensate must be prevented by technical means. This means that the engine must undergo fundamental modifications. The illustration shows the key conversion work for an OM 471 Euro VI engine:

Engine software specifically adapted to the conversion measures ensures fault-free engine operation.

Exhaust gas recirculation is reduced to minimize the forma-tion of condensate.

A fuel prefilter with a knockout reduces the ingress of water into the injection system.

Modified ventilation of the crankcase reduces the formation of condensate in the engine.

Thanks to the modified exhaust gas recircula-tion, a modified exhaust manifold ensures

that the engine continues to run smoothly.

Choice of Sulfur Robustness Packages

Mercedes-Benz offers the Sulfur Robustness Packages in two versions for different emission standards. As a result of the technical conversion, the vehicle no longer meets the EURO V/VI emission standard valid in Europe and other countries. Please note that the relevant national emissions regulations in the country of use must be adhered to when operating the vehicle.

The standard variant of the Sulfur Robustness Packages provides extensive protection and compliance with the Euro III emission standard. The extended variant provides maximum sulfur compatibility for OM 471 series engines, however this can only be achieved by disabling the exhaust gas recirculation and therefore loss of the emissions classification.

Important: After conversion the vehicle no longer meets the EURO V/VI emission standard valid in Europe and other countries. Driving on public roads is therefore not permitted. Please consult the relevant road traf-fic authority for possible exceptions. It is the vehicle owner’s/operator’s responsibility to report the changed emissions classification to the relevant road traffic authority. Furthermore, the conversion leads to technical restraints affecting the vehicle (reduced output, increased fuel consumption, limited diagnostics and shorter maintenance intervals), which are shown in complete form on page 7 of this product documentation.

The technical effects of a conversion

Converting the engines with the individual packages has effects on various vehicle parameters:

• Reduced output • Deactivation of the function „Predictive Powertrain Control“ (PPC) and „Top Torque“ • Only driving mode „Power“ can be used • Fuel consumption may increase • Maximum sulfur content 2000 ppm* to maintain the engine’s functionality • Changed maintenance intervals owing to the sulfur content in the diesel fuel:

– sulfur content 500 ppm* or less – normal maintenance interval (max. 120,000 km) – sulfur content 500 –1000 ppm* – 50% shorter maintenance interval – sulfur content 1000 – 2000 ppm* – 75% shorter maintenance interval

• Limited diagnosability

Mercedes-Benz truck engine oil: the oil that deserves our star.

Mercedes-Benz genuine oil is the ideal lubricant for a Mercedes-Benz truck engine. This is precisely what it is developed and configured for. The advantage: the detailed kno- wledge of the engine designers is incorporated during production. The result is an oil that fully meets the requirements for a Mercedes-Benz. Selected components and additives are configured for the vehicle’s technology and the seasonal circumstances, i.e. for particular mechanical and thermal loads. The oil also performs other important tasks, for example cooling parts subject to heat stresses or corrosion protection.
