HANOVER, Germany — Making good on a previously stated goal to increase market share in the commercial vehicle emissions solutions industry, ArvinMeritor has unveiled a portfolio of original equipment aftertreatment products in Europe called its Clean Air Solutions.

This high-tech collection is intended to help operators meet stringent 2008 Euro 5 exhaust emissions standards for commercial vehicles — and will likely play a role in North America’s upcoming 2010 standard. The technologies are on display this week at the ArvinMeritor exhibit at the IAA Show in Hannover, Germany.

“These technologies currently include commercialized products that meet Euro 4 requirements of 2005 and a number that satisfy the stricter dictums of Euro 5 and the coming years,” says Silvio Angori, general manager of Commercial Vehicle Emissions.

Arvin tapped into the NA ’07 emissions solutions market.

On display at the ArvinMeritor exhibit are the following emissions technologies for original equipment commercial vehicle applications:

Light-duty diesel particulate filter system – Diesel particulate filters (DPF) remove smoke, soot and other particulate matter from the exhaust. The accumulated soot is continuously removed by reaction with nitrogen dioxide from the engine when the exhaust temperature is suitably high. Nitrogen dioxide is generated from the nitric oxide produced by the engine, by catalytic reaction over a diesel oxidation catalyst (DOC) upstream of the filter.

Heavy-duty SCR system — Selective Catalytic Reduction (SCR) is a means of removing nitrogen oxide (NOX) pollutants from the exhaust gas. This technology — the main solution for European regulations and the stated future solution for some North American truckmakers — is achieved by injection of a reducing agent, “AdBlue,” which reacts with the NOX over the catalyst to produce nitrogen (N2) and water (H2O).

This aftertreatment system combines the SCR catalysts and noise attenuation elements in a single compact package.

Emission system to meet EEV legislation — This system combines key technologies to meet EEV legislation. All are integrated in one compact unit for packaging optimization. Technologies that are integrated include a diesel-oxidation catalyst (DOC) for hydrocarbon reduction (HC), an SCR-catalyst (SCR) for nitrogen oxides reduction (NOX), a serviceable diesel particulate filter (DPF) for particulate reduction (PM) and a urea injection nozzle, as well as other emission relevant components.

Atomizer — A fuel-injection system used to actively regenerate diesel particulate filters and/or lean NOX traps. Diesel fuel is injected onto a catalyst where it oxidizes catalytically to generate heat that is used to enable oxidative regeneration of a diesel particulate filter.

Thermal Regenerator — An active unit that enables regeneration of DPFs under any engine or vehicle operating condition. Its design has been conceived to allow for applications where installation constraints require compact size and versatility of inlet and outlet configurations. The unit consists of a diesel particulate filter and a combustor unit.
