 Fuel System/Component Suppliers
 Fuel Refiners
 After-treatment Suppliers
 Original Equipment Manufacturers
Leaders in Promoting
Clean Diesel Technology
Why Emissions Upgrades?
New
engine technology only
affects a fraction of the fleet
Voluntary action can address the
fleet of engines in-use
Inherent value of diesel technology

Modernizing and Upgrading:
The 5 R’s
 Retrofit–new emissions control devices on
existing engines. (CRTs)
 Refuel – cleaner diesel fuel,
emulsions/additives (ULSD)
 Rebuild – repair/upgrade key components or
ECM programming
 Replace – vehicle/equipment condition <
value of new engine.
 Repower – newer engine in existing equip. or
chassis
Clean Diesel System
Advanced engine electronic
combustion control , fuel injection
systems, and turbochargers optimize
performance and low-emissions
Advanced Engine
Technology
Clean
Diesel
System
Cleaner Diesel
Fuels
Ultra low Sulfur Diesel Fuel
produces lower emissions and enable
advanced emissions treatment
systems (catalysts and filters)
Emissions
Treatment
Particulate filters, oxidation catalysts
reduce emissions of ozone-forming
compounds (NOx and VOCs), trap
and eliminate fine particles
Modernizing and Upgrading Existing
Diesel Engines
 “Technology
Buffet”
Many choices emerging –
traps, filters, catalysts, fuels, additives,
devices.
 What
makes the most sense for the
application?

Retrofit: What works?
Not all technologies work on all engines
 Verify
– performance, effectiveness
– stakeholders, users,
regulators and legislators
 Educate
 Implement
 Evaluate
– incentives
performance,
calibrate/adjust, communicate
success and failures
Forum Retrofit Objectives
 Demonstrate
 successful
voluntary diesel emissions
reduction programs
 that diesel technology is a big part of the
solution to future mobile source pollution
and energy conservation objectives
 Communicate
the capabilities of diesel
to fleet operators, regulators,
government officials and opinion leaders
 Ensure technology compatibility,
optimum product performance and
emissions reductions

Helping to identify fleets that are good
candidates for retrofit
Helping coordinate the provision of technical
guidance to the target fleets to ensure that the
right engines are selected for retrofit, and that
retrofits are performed properly
Maintaining a web-based retrofit resource
Ensuring that new diesel retrofit technology is
accepted by the EPA and States
Ensuring that emissions benefits are maximized
for the benefit of participants and state
compliance
Our Advice to “Users”
 Do
your homework– know your equipment,
the $$$, capabilities, rationale.
 Make good choices –which option works
best in your fleet/business– get the
resources– dealers and manufacturers,
suppliers EPA, DTF.
 Get the right “Technical Fit” –
performance, maintenance, reliability
(government, suppliers and users).
 Measure
& Communicate your progress --
Share experiences
What will make Retrofit a Success?
 Technical
exploration and investment
 “Easy”
integration of technology with
existing engines
 Funding
and marketing
 Understanding
users
the target audience of
Onward !
 Check
our website for information:
www.dieselforum.org
 Consider
smoke testing legislation
 Identify and work with regional leaders
on a cooperative retrofit effort
 Work with legislators on retrofit funding
 Communicate with stakeholders
 Use the Diesel Technology Forum as a
sounding board for program ideas
