EPA: Navistar might have been “forced out of market” without fines - discover Diesel Exhaust Fluid (DEF)

EPA: Navistar might have been "forced out of market" without fines

Navistar might have been forced out of the Class 8 truck market had theEnvironmental Protection Agency (EPA) not permitted the manufacturer continue producing non EPA 2010-compliant engines based on Nonconformance Penalties (NCP).

In a briefing on the decision to let Navistar pay fines, the EPA said it was permitted to enforce penalties for "technological laggards", which "might be unable to comply and would be forced out of the marketplace".

Navistar's competitors have begun a legal challenge against the EPA over its decision to allow the manufacturer to continue producing non EPA 2010-compliant engines. The case, which was filed in February and began hearing oral evidence on 18 May 2012, has been brought by Mack Trucks, Volvo Group North America, Daimler Trucks North America, Detroit Diesel Corp and Cummins.

Volvo said in a legal brief: "It was not that Navistar lacked the technological know-how to use SCR technology. It just chose not to. Navistar gambled that it would produce a non-Selective Catalytic Reduction (SCR) compliant engine without running out of credits," according to the Wall Street Journal.

Navistar said it "chose the hard technology path," in its court filings.

The EPA said in its defence that halting production would cost the company at least $3 billion, more than 30% of its annual revenue, according to the Wall Street Journal.

Navistar ran out of emissions credits, which it had previously relied on to meet the emissions standards in its GVWR >14,000 pounds engine family, on 29 February 2012. The EPA said it would impose a penalty of at least US$1,900 per non-compliant engine after this point.

Navistar is the only manufacturer not to use SCR in its EPA 2010 models and has not yet certified a 13-litre engine at below the 0.20 gram of nitrogen oxide per brake-horsepower hour standard set out in EPA 2010.

A technological laggard is defined by the EPA as "a manufacturer who cannot meet a particular emission standard due to technological (not economic) difficulties and who, in the absence of NCPs, might be forced from the marketplace".

Marc,

Just a quick FYI example of what we are working on, this is a DEF control unit that is leaking. Step by step repairs and then retest.

Cummins 2013 Engine Info:

NEW ORLEANS - Cummins Inc. (NYSE: CMI) unveiled the complete product portfolio for the transit bus market at the American Public Transportation Association (APTA) Expo in New Orleans from Oct. 3 to 5. Cummins showcased diesel, diesel-electric hybrid and natural gas engines designed to meet the 2013 U.S. Environmental Protection Agency (EPA) emissions regulations and new greenhouse gas (GHG) and fuel-efficiency standards.

The EPA 2013 emissions regulations call for all on-highway engines to be equipped with On-Board Diagnostics (OBD). OBD monitors emissions- related engine systems and components and alerts the operator of any malfunctions. OBD is designed to further enhance the engine and operating system by providing early detection of emissions-related faults.

In addition, new regulations for 2014 have recently been finalized by the EPA and the U.S. Department of Transportation (DOT), instituting equivalent carbon dioxide (CO2) and fuel-efficiency standards. By burning less fuel in the engine, CO2, which is the main GHG controlled under this regulation, is simultaneously reduced. Nitrous oxide (N2O) and methane (CH4) are the other regulated GHGs.

Cummins has announced that it will meet the OBD as well as the GHG and fuel-efficiency requirements by Jan. 1, 2013. "The ability to meet the GHG reduction standards ahead of time alongside the OBD requirements for 2013 allows us to assure customers that we are committed to bring clean products to market even sooner," stated Tom Hodek, General Manager - North America Bus Business. "This approach provides customers with a single product launch so transit bus properties will not be faced with further product changes for 2014."

Cummins will build upon the success of their EPA 2010 MidRange product platform with the same capable base-engine architecture for 2013. The 2013 ISL9 (with 280 hp [209 kW] and 330 hp [246 kW] ratings available for transit buses) will continue to deliver exceptional reliability and dependability driven by the proven technology of the XPI common-rail fuel system, VGT™ Turbocharger and fully integrated electronic controls. The addition of an air intake throttle for 2013 will also create a closed-loop system, improving the efficiency of the engine and aftertreatment system. This will result in the ability to better optimize the balance of performance, fuel economy and emissions control, which in turn will deliver the durability and reliability that Cummins customers have come to expect. The Cummins Aftertreatment System with Selective Catalytic Reduction (SCR) technology will remain as the technology solution for 2013 to deliver near-zero emissions and industry-leading fuel economy.

The 2013 Cummins Westport ISL G natural gas engine (with 250 hp [186 kW], 280 hp [209 kW] and 320 hp [239 kW] ratings available for transit buses) will remain as a key element in the Cummins product portfolio for the transit bus market. As the industry-leading MidRange alternative-fuel engine, the ISL G will continue to deliver reliable, clean power to meet transit bus customers' specific needs. Cummins will also continue to offer the ISB6.7 and ISL9 diesel-electric hybrid engines.

"Cummins continues to offer customers multiple engine options designed for their specific transit bus needs that will meet OBD and GHG emission regulations," emphasized Hodek. "This will continue to position Cummins as a leader in the transit industry, delivering reliable products backed by a highly capable support network today and for years to come."

Solid ammonia SCR

DieselNet Paper Explores The Solid Case For SCR
A technical paper "Solid Reductant Storage for SCR Systems," has been published on DieselNet.com. The paper discusses SCR systems that use a solid ammonia precursor and deliver gaseous ammonia reductant to the SCR catalyst. It is anticipated that Navistar will launch an engine with the Amminex solid SCR system

DEF Tank Info.

Recent issue with the DEF Tank being empty, Engine CEL, low power, Insite thought the tank had 84% DEF and we had four bars on the DEF Tank gage.

 

Will follow up with what the cause was, as well as the repair being made.
