Exhaust flows through porous wall-flow elements – PM is trapped on the walls of the filter

When exhaust temperature is high enough, PM is burned off – In most cases, unburned diesel fuel is injected to accomplish this

Precious metal is loaded onto filter walls to lower the temperature required for regeneration (i.e. burning trapped carbon to CO2).

Issues the PM system must overcome : – Regeneration at low temperatures/duty cycles

– Plugging with incombustible materials like lube oil ash

BQ-9000 AND FUEL QUALITY

The biodiesel industry has an excellent fuel

quality program called BQ-9000

(www.bq-9000.org)

Helps ensure that only the highest-quality

biodiesel meeting ASTM specifications is

produced

ASTM Grade Fuel, BQ-9000 Companies

Over 90% of US biodiesel produced is by

BQ-9000 accredited companies.

HEALTH HEALTH BENEFITS IN ILLINOIS

“Vehicles fueled with B20 biodiesel generate fewer harmful emissions that contribute to asthma, bronchitis,

cardiovascular disease and other health ailments. Considering hospitalizations, lost work days and other

health costs, using B20 translates into an estimated savings of $1,218,100 for the communities where B20

Club members operate.” – John DeRosa, Director of Clean Air Initiatives, American Lung Association

SUMMARY

The Clean Air Act has been successful in dramatically reducing air

pollution in the United States.

Reduction in pollution from all types of motor vehicles has been

critical to meeting air quality goals.

Regulation of motor vehicle fuels at the national level, combined with

local fuel requirements, has brought many areas to within health-

based air quality standards.

Use of oxygenates in fuels, primarily ethanol, has been an important

component of fuels programs in the U.S.

Both Ethanol and Biodiesel, will play a very strong role in national

fuels programs in the future, including efforts to address GHG

emissions.
