PIRATE ELECTRONIS UNITS * Belgium: Modifyng emissions from diesel trucks

* Brussels - Emissions of diesels: engine rigging software flourishes on canvas

--- Pirate electronics units intended to modify the emissions of nitrogen oxides from diesel trucks have been available on the Internet since the application of Euro 5... In order to contain nitrogen oxide emissions from truck diesel engines within Euro 6, all manufacturers use an AdBlue injection in the exhaust gases (SCR process). The device that controls its operation can be neutralized by pirate software for sale on the Internet... Cheating involves providing permanent false information to the central management unit: "everything goes well on the side of catalytic reduction" while the AdBlue tank is empty... The pirated electronic boxes called "AdBlue emulators" are available on the Internet since the application of Euro 5 at derisory prices (a few tens of euros) with sometimes a certificate of quality awarded ... in China! Some professionals propose the installation of pirate boxes in a more ambiguous way, with a temporary activation to reach an AdBlue refueling point... The after-sales networks have observed cases of use of AdBlue emulator on vehicles coming mainly from countries of the East... But in the case of a system with switch, is detection possible? Yes, because the AdBlue injection device does not adequately support prolonged inactivity while the engine is running, which will result in high costs during a refurbishment... DAF and Scania sent a circular to their network stating the legal consequences of any reprogramming of the engine and the depollution devices: loss of the manufacturer's warranty, loss of the right of movement (non-conformity with the homologation of origin) therefore, loss of insurance... On 13 January 2017 a European motion for a resolution concerning the standards governing the motor vehicle industry, and in particular their control, was drafted, inter alia, with an explicit request to prohibit any device for invalidation and to make the homologation mandatory softwares...

SCR * USA & Europe - AdBlue manufacturers warn of incorrect use

* Europe - Dangers of certain derivations observed since the introduction of the SCR systems

Brussels,Belgium -Fleet Europe, by Claude Yvens -18 Feb 2011: -- In a first of its type, the six main producers of AdBlue (Air1, BASF, Borealis, GPN, Greenchem and SKW) are to apply a common approach to launch a communications campaign with the support of European manufacturers (via their representative association ACEA). They wish to advise fleet operators of the dangers of certain derivations observed since the introduction of the Selective Catalytic Reduction (SCR) systems in 2006:

- the deliberate choice of a product which does not meet AdBlue norms

- storage in containers which have previously held diesel or other chemical products

- mixture of AdBlue and diesel in the fuel tank

This incorrect use of the product can cause irreparable damage to the engine and, in certain cases, lead to all guarantees on the vehicle becoming nullified...

* USA - DEF availability up while cost is down, says research firm

(Photo: Pilot Travel Centers operate the largest number of DEF pumps in the U.S.)

New York,NY,USA -Fleet Owner, by Sean Kilcarr -Feb 25, 2011: -- One of the concerns among trucking companies buying commercial trucks equipped with selective catalytic reduction (SCR) technology revolves around easy access to a critical ingredient required by this emission control system to reduce exhaust pollution down to government mandated levels: DEF, short for “diesel exhaust fluid” ... DEF is a liquid solution comprised of 67.5% de-ionized water and 32.5% urea, an ammonia compound, that’s sprayed into an SCR-equipped truck’s exhaust stream where it combines with a catalyst to break down oxides of nitrogen (NOx) into nitrogen and water. Without DEF, then, the SCR system doesn’t reduce NOx emissions... Yet ongoing surveys of the U.S. and Canadian transportation markets by global consulting firm Integer Research finds that DEF availability is rapidly expanding, while the cost for this critical substance is dropping as well... He also noted that the ”pump price” of DEF per gallon has declined steadily since last year, which is important as the lower the cost of DEF becomes, the lower the overall price of operating an SCR-equipped vehicle becomes – particularly in the face of rising diesel fuel costs...

Selective Catalyst Reduction * USA - Ryder to offer DEF at all full serve locations

Ryder System is certainly not tone DEF

Miami,FL,USA -Todays' Trucking (USA)-17 Nov 2010: ... The truck leasing giant will soon offer at every full service North American location, diesel exhaust fluid (DEF) required for many 2010 engines... This offering will support contractual full service lease and maintenance customers operating vehicles that use selective catalytic reduction (SCR)... Customers will be able to purchase DEF in 2.5-gallon portable containers. Ryder will also begin adding bulk storage and DEF pumps at its largest shop facilities throughout North America in 2011... As well, a limited supply of DEF will be available at non-fueling locations for emergency roadside service needs... Supply will increase as demand grows, says the company... DEF is the non-toxic, urea-based solution to virtually eliminate NOx emissions from diesel engines... All major truck OEMs with the exception of Navistar is marketing SCR engines in model 2010 trucks... (Photo from t2.gstatic: In a SCR system, Diesel Exhaust Fluid (DEF) is combined with engine exhaust in the catalyst to convert harmful NOx into harmless Nitrogen and water vapor.)

EGR vs SCR * USA - Navistar: Scrap current '10 engine rule; recall SCR trucks

As rivals often point out, while Navistar criticizes SCR systems' ability to comply with the 2010 standards, it does not yet have an engine that meets the EPA's 2010 NOx limit

Washington,DC,USA -Today's Trucking -2 Sept 2010: ... Navistar is now calling on the agency to force a recall of those engines currently in the market and introduce a new guidance that requires SCR engines to shut down immediately when out of diesel exhaust fluid (DEF)... A new rule should require SCR engines to employ sensors that "immediately" recognize the difference between proper DEF and the wrong fluid or an empty DEF tank, the company urges... At the meeting, in which competitors Daimler Trucks, Volvo and Cummins begrudgingly observed, Navistar demanded that regulators fix "loopholes" which allow trucks to continue operating in a derated mode if DEF runs out or is substituted with another liquid... In a video demonstration, Navistar showed that some trucks can operate without DEF for extended periods and freely driven up to 11,000 miles with water in place of DEF, thereby "illegally" relaxing -- Navistar claims -- the agency's own 0.20g NOx standard... SCR competitors counter that the demonstration is misleading since, in actuality, sensors would identify the NOx limits being breached and the system would initiate a derating "inducement," which would eventually shut the truck down at the next fuel fill-up interval...

SCR vs- EGR * USA - Daimler Trucks North America LLC, to the Trucking Industry

Don't trucking industry customers of North America deserve better?

Portland,OR,USA -DTNA press release -10 Aug 2010: -- "We had a decade to prepare for 2010 emissions standards and all but one heavy-duty trucking manufacturer invested the time, money and brainpower to develop the best technology to meet stringent new requirements. All but one manufacturer, Navistar, came to the same solution that would best serve you, our trucking industry customers of North America... Although we're competitors, the rest of us understood the importance of the larger cause, and we worked together to do our part to improve air quality for the safety of future generations. How can Navistar claim it's concerned about the environment while its proposed 2010 product spews two and a half times the 2010 NOx standard into the air we breathe every day?... Manufacturers, suppliers, government agencies and associations invested time and resources to develop innovations to achieve the emissions goal in spite of economic challenges because we know it's the right thing to do... Navistar is selling thousands of pre-2010 engines, while the rest of the industry is selling EPA 2010-certified products. Navistar apparently has no EPA-compliant emissions technology for 2010 and beyond, at least nothing that does not use credits to achieve compliance... Don't trucking industry customers of North America deserve better? We believe you do. And, as an industry that prides itself on professionalism, integrity and honesty, we have every reason to demand the same of Navistar... Learn more about SCR and watch real customers discuss the benefits of this technology." (Image from daimler-trucksnorthamerica: Portland, Ore., Truck Manufacturing Plant )

SCR Technology * USA - Navistar Withdraws CARB Lawsuit Over

Warrenville,ILL,USA -Transport Topics -23 April 2010: -- Navistar International Corp. has withdrawn a lawsuit that it had filed against the California Air Resources Board, following an agreement with CARB that addressed the engine-related issues that prompted its original court action... Navistar had sought a ruling in a San Francisco Superior Court declaring that CARB was improperly certifying 2010 diesel engines equipped with selective catalytic reduction technology for nitrogen oxide emissions control... The suit charged that CARB was applying certification requirements which permitted SCR-equipped diesel powered trucks to operate for extended periods without any control of NOx emissions... Navistar said it dismissed the suit after reaching an agreement with CARB in which the board agreed that the 2009 guidance documents are not its policy... Navistar has filed a separate lawsuit in federal appeals court...

SCR's TROUBLES * Belgium - SCR trucks failing to hit Euro-5 standards

Brussels,Belgium -Road Transport (UK), by Dominic Perry -21 March 2010: -- Operators of SCR-equipped Euro-5 trucks will be forced to modify their vehicles making their trucks less fuel efficient if the EU decides to back recommendations put forward by the Dutch government... The move comes on the back of a study in Holland, which revealed that NOx emissions from Euro-5 trucks in the urban environment were only marginally better than those of Euro-3 vehicles, despite theoretically being 60% lower... Flach points out that the majority of NOx is produced during a high-temperature duty cycle - unlikely to occur during urban operation. Equally, the on-board diagnostics (OBD) fitted to Euro-5 trucks since 2007 should prevent NOx emissions at the levels suggested by the study, he says... He stresses that regardless of this, the EU is unlikely to agree the stop-gap measure before the roll-out of Euro-6...

SCR * Australia- Now, a car that uses urine to cut its harmful emissions

Reports indicate that Mazda's new CX-7 four-wheel-drive uses a urine-like solution to cut its tailpipe emissions

London,UK -The London News.Net (Manama, Bahrain) -14 October, 2009: ... According to a report by Fairfax Digital, the compound, called AdBlue, is a mixture of roughly one-third pure urea and two-thirds demineralised water... The technology, called selective catalyst reduction, involves injecting the urea-based liquid into the car's exhaust system to turn NOx emissions into harmless nitrogen and water... To guard against forgetful drivers not filling its AdBlue tank, the Mazda CX-7 diesel will cut its maximum speed if the level of AdBlue falls below a certain level... The car will not start if the AdBlue tank is empty... The 15.5-litre tank is mounted under the rear-floor of the CX-7 and Mazda recommends the task is undertaken by an authorised dealer as part of scheduled servicing...

CHALLENGE * USA - Navistar vs. EPA

Navistar sues over engine technology

Warrenville,ILL,USA -eTrucker -30 May 2009: -- On March 31, Navistar Inc., quietly filed a challenge in a federal appeals court to the Environmental Protection Agency’s Feb. 18, 2009 certification requirements for heavy-duty engines using selective catalytic reduction (SCR)... On May 4, the truck maker submitted a statement of issues to the U.S. Court of Appeals for the District of Columbia raising the question of whether EPA can adopt the 2009 SCR guidance without a rulemaking proceeding... Navistar charges that the 2009 SCR guidance relaxes the 0.2 gram standard and approves a control technology that EPA in 2001 concluded would not allow the standard to be met on a fleetwide basis... The truck maker also alleges the 2009 guidance imposes entirely new regulatory requirements and allows diesel engine manufacturers to release uncontrolled NOx emissions on the highway, create highway safety hazards and certify engines to an emission standard that the engines will exceed. In the statement of issues, Navistar also contends, among other things, that the 2009 SCR guidance:

# Improperly amends the 2001 rule establishing the 0.2-gram NOx standard;
# Reverses the 2001 “infeasibility” finding in a way that requires another rulemaking;
# Approves a control technology that causes or contributes to an unreasonable risk to public health, welfare or safety;
# Authorizes operation of diesel engines with their emission control devices bypassed, defeated or rendered inoperative; and
# Ignores EPA’s own “not-to-exceed” emissions standards.

Under an April 3 order from the court, further briefing in the case is deferred until further notice...

TRUCKMAKERS' ENGINES DEBATE * WORLDWIDE - SCR or EGR ?

Linkedin (USA)/"World of Trucks" group, by Jim Mele -10 March 2009: -- ("Volvo: SCR will cost $9,600": USA -Fleet Owner -March 03, 2009)... Do you expect the other OEMs to be in the same range? What about Navistar and its "Advanced EGR" approach?

* USA - Navistar does seem to have a lot of questions to answer

Linkedin/"World of Trucks" group, by Oliver Dixon (London,UK) -10 March 2009: -- Taking MAN's Euro V engine and making it Euro VI compliant (EPA 07 to EPA 10 in all but name) seems like a pretty neat trick, especially given that MAN has said no can do without a very significant increase in diesel consumption. Hence MAN's embracing of SCR for Euro VI, and the surely reasonable observation that NAV's achievement of an EGR-based MAN-designed engine that is both MPG-neutral and EPA 10 / Euro VI compliant has all the appearance of a deal brokered by Mephastophilis. Denmark and noxious odours come to mind... If we are to believe NAV's assertions, then we have to believe that an awful lot of people - including those who designed and engineered the Maxxforce engine in the first place - have got things very wrong, and NAV has got things very right. Will NAV now resell MAN's engine back to MAN for Euro VI? This has the potential for much merriment and high comedy. Followed by red faces and the large servings of humble pie.

However, in order to prevent efficiency failure in required NOx adsorbers, the urea needs to be periodically replenished. With just over two years to go before the standard kicks-in, there still isn't any viable urea infrastructure in place in North America

New York,NY,USA -Today's Trucking (CAN) -30 July 207: -- ... A consultant who specializes in designing and developing urea dispensing systems told New York trucking market analyst firm Bear Stearns that there is now a "general consensus" among heavy truck OEMs that selective catalyst reduction -SCR- will likely be the most practical technology for reaching EPA-mandated 2010 NOx-reduction standards... The SCR system -- which injects a nitrogen containing agent like urea into the exhaust gas upstream of the catalyst to further eliminate NOx emissions -- is the technology that's being used in Europe for meeting emission standards over there... The EPA wants truck and engine OEMs too ensure they can prevent truckers from driving 'urealess' when the tank is empty...
