Being the most critical pollutants, NOx and PM have been both reduced by approximately 60% since 1996.The next big challenge will come in January 2014, when a new limit established by Tier4Final/Stage IVemission regulations will call for a further drastic reduction of Nitrogen Oxides at more than 80% vs.

Tier 4 Interim/Stage IIIB legislation.

Caring about the environment.

Both in the US and Europe many efforts have been carried out to make Diesel engines as clean aspossible. Engines must be environmentally friendly during their entire life period and under a widerange of operating conditions.Starting from 2014, Tier 4 Final/Stage IV regulations will firstly concern engines with power above130kW to be then extended to other power ranges.Tier 4 Final/Stage IV compliance implies a significant reduction of NOx (-80%) over todaysTier 4 Interim/Stage IIIB levels, while PM is not affected by further reduction, having already reacheda 90% abatement in the previous step.

The Tier 4 Finals request: massive reduction of NOx.

FPT Industrials answer: SCR Only technology.

Due to the opposite reaction to combustion temperature, the reduction of either of the combustionproducts (NOx or PM) necessarily implies the increase of the other one.

In order to further reduce NOx, as required by Tier 4 Final/Stage IV, it is necessary to work on differentcombustion management and exhaust gas treatment systems.

SCR (Selective Catalytic Reduction) Only technology is an after-treatment system that transforms theNOx produced during the higher temperature combustion process into Nitrogen (N

2) and Water (H

2O),

both of which are naturally occurring chemicals in the atmosphere.

Thus the use of SCR Only technology allows NOx reduction, occurring downstream the engine,and optimizes at the same time combustion process and engine performance.

Starting from the Tier 4 Interim/Stage IIIB,SCR Only technology allows exhaust emissions to complywith Tier 4 Final/Stage IV emission level in two simple steps.

The high temperaturecombustion engine

calibration producesNOx and a verylimited amount of PM.

SCR Only: how it works.

The SCR after-treatment system adopts a catalyst converting NOx into Nitrogen (N2) and Water

(H2O) thanks to the chemical reaction with a Water-Urea solution (DEF: Diesel Emission Fluid/AdBlue).The Water-Urea solution is a non toxic, colourless and odourless mixture of chemical urea anddemineralised water.The whole system is controlled and managed by the Engine Control Unit (ECU), according to differentpower, torque and emission levels.

The main components of the SCR system are:

Supply Module Dosing Module SCR Catalyst with integrated CUC DOC DEF/AdBlue Tank

The ECU (Engine Control Unit), the brain behind the SCR system, checks, through sensorsintegrated in the exhaust, the amount of Water-Urea solution to be injected in the exhaust pipe,producing steam, ammonia (NH

3) and nitrogen oxide (NO). To minimize the use of DEF/AdBlue, the

injector is cooled by the engine coolant. Next, the remaining substances enter the DOC (DieselOxidation Catalyst), where NO is converted in NO

2, to reach a 50:50 ratio between NO

2and NOx, to

maximize the SCR performance also at low temperature. In the SCR catalyst NOx is converted in N2 andH2O while the integrated CUC (Clean Up Catalyst) eliminates the remaining ammonia (NH

3).

The result is a reduction of NOx superior to 95%.

SCR main components.

Supply Module:the unit that pressurizes andpumps Water-Urea solution.The Supply Module, as wellas the whole SCR system,management is demanded toEngine Control Unit.

Dosing Module:is the unit responsible for the injectionof Water-Urea solution inside the SCRcatalyst. It is managed by the EngineControl Unit.

DEF/AdBlue Tank:is the storage placeof Water-Urea solution on the

vehicle. It contains fluidtemperature and levelsensors.

DOC:is a key component which increases the SCRperformance especially at low temperatures.

SCR Catalyst with integrated CUC:is the part of the system where chemical

reduction takes place.

10 reasons for choosing SCR Only.

1) Lower Fuel consumption: the efficiency of the combustion process optimizes fuel consumptionreducing customer running costs.

2) Outstanding Performance: being SCR an after-treatement system, the engine is designed tomaximize torque and power with the shortest load response time.

3) Longer Service interval: the optimized combustion process preserves oil physical propertiesreducing maintenance activities and related downtime.

4) High Reliability: SCR system allows the engine to reduce heat rejection of many internalengine components which leads to better reliability.

5) Unbeatable Durability: SCR system is engineered for life. The reduction of PM inside theengine grants total absence of clogging problems and excludes any regeneration intervention.

6) Compact packaging: compared to competitors engine, the thermodynamic efficiency of SCRsystem allows to downsize displacement enhancing performance.

7) Wide Fuel Compatibility: SCR system works regardless fuel quality. In the FPT Industrial SCROnly technology the catalyst substrates are not influenced by the presence of traditional poison-ing substances in the fuel such as sulphur.

8) User friendly solution: SCR system is simple. The only thing to do is refilling urea when thelevel indicator in the vehicle instrument cluster flashes.

9) Environmental care: thanks to SCR system pollutants produced during the combustion process areconverted into harmless N

2and H

20, already present in the environment.

10) Advanced technology: SCR Only is recognized by most of the engine manufacturers as the technologyof the future to be compliant with Tier 4/Stage IV.

Where will the SCR Onlybe commercialized?

Will DEF (Diesel Emission Fluid)/AdBlue be distributed also in theUSA?

Is there any critical issue regarding

SCR Only introduction in the USA?

What does it happen if DEF/AdBluetank is empty?

Is the SCR system affected by lowtemperatures?

Has SCR installation constraints?

SCR Only will be commercialized in all the countries where the emissionregulations will require Tier 4 Final /Stage IV standards.

Yes.

No, because by 2011 the DEF/AdBlue distribution network will be developedin the USA (many American engines manufacturers will adopt SCR Onlyfor EPA10 on road compliances).

A led on the vehicles cluster will switch on and the engine will be switch tolimp home mode to preserve the safety and emissions compliance.

No, FPT Industrial SCR system perfectly works at low temperature. Even in caseof cold start with DEF/AdBlue frozen (temperature below -11C/12F) the engineworks properly without any derating.

No. Of course OEMs have to respect FPT Industrial SCR installation guidelines.The system is engineered in order to be easy to install, with flexibility in terms oflength of pipes & height positioning.
