Diesel Particulate Matter •! "Particulate matter," also known as particle pollution or PM, is

a complex mixture of extremely small particles and liquid droplets. Particle pollution is made up of a number of components, including acids (such as nitrates and sulfates), organic chemicals, metals, and soil or dust particles.

•! The size of particles is directly linked to their potential for causing health problems. EPA is concerned about particles that are 10 micrometers in diameter or smaller because those are the particles that generally pass through the throat and nose and enter the lungs. Once inhaled, these particles can affect the heart and lungs and cause serious health effects. EPA groups particle pollution into two categories:

–! "Inhalable coarse particles," such as those found near roadways and dusty industries, are larger than 2.5 micrometers and smaller than 10 micrometers in diameter.

–! “Fine particles," such as those found in smoke and haze, are 2.5 micrometers in diameter and smaller. These particles can be directly emitted from sources such as forest fires, or they can form when gases emitted from power plants, industries and automobiles react in the air.

•!VERIFICATIONS

EPA verifications are specific as to the

percentage(%) of PM, HC and CO reduction.

For example, the ECS Purifilter™ Passive

DPF is EPA verified to reduce:

Particulate Matter (PM) - 90%

Hydrocarbons (HC) - 85%

Carbon Monoxide (CO) - 75%

EPA VERIFICATIONS

CALIFORNIA VERIFICATION Classifications

for Diesel Emission Control Strategies

Pollutant Reduction Classification

PM

< 25% Not verified

> 25% Level 1

> 50% Level 2

> 85%, or < 0.01 g/bhp-hr Level 3+

CARB verifications only indicate Level of PM reduction.

The same emission retrofit technology may be verified by both the

EPA and CARB.

There are significant differences in complying with each

verification and, importantly, in pollutant(s) verified as reduced.

Most states, except California, may accept either EPA or CARB

verification of emission retrofit technology.

California will only accept CARB Level 3+ verification for retrofits.

In some (very rare) instances, CARB may accept Best Available

Control Technology (BACT) but never less than Level 2.

Emission regulations are subject to change. Check the

appropriate (CARB or EPA) website for current rules.

Did you know?

Important Footnotes

•! Emission Standards are based strictly upon the manufacture

date of the engine and the engine family.

•! Example: The 2011 model year for new vehicles began in July

2010. A 2011 model year vehicle may have an engine

manufactured in 2010 or 2011.

•! Retrofitting an engine does not change its certification.

Installation of verified retrofit technology only reduces the

pollutant(s) as shown in the verification document.

More Footnotes (generalizations)

•! Emission retrofit devices are verified for engines manufactured during

specific time periods, e.g., 1991 – 2004, 1994 – 2006, etc. Some

CARB verifications reference Tier Levels for off-road engines.

•! All CARB approved devices are only verified for installation on

specific engine families.

•! Refer to the approval document for the specifics of verification.

•! Diesel Oxidation Catalysts (DOC) are not verified for off-road applications (except Port &/or intermodal for specific engine

families).

•! Passive Diesel Particulate Filters (DPF) have exhaust temperature

duty cycle requirements.

•! There are limitations as to which emission retrofit technology may be

installed on engines equipped with Exhaust Gas Recirculation (EGR).

Table 2.1.c). Purifilter and Purifilter Plus Sizing for 1994 and newer highway engines

Purifilter Plus DPFs are sized using the same chart and have the letter “P” in the third position. For example, the Purifilter model SC23 changes to SCP23 when the Purifilter Plus is specified.

*For four stroke engines with turbocharging and charge air cooling. **Overlap in sizing required to address greater exhaust flow of higher power versions as well as dual exhaust vehicles.
