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

Emissions Treatment

Clean

Diesel

System

Advanced Engine Technology

Cleaner Diesel Fuels

Ultra low Sulfur Diesel Fuel

produces lower emissions and enable advanced emissions treatment systems (catalysts and filters)

Particulate filters, oxidation catalysts reduce emissions of ozone-forming compounds (NOx and VOCs), trap and eliminate fine particles

Advanced engine electronic combustion control , fuel injection systems, and turbochargers optimize performance and low-emissions

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

Educate – stakeholders, users, regulators and legislators

Implement – incentives

Evaluate 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

Forum Activities

State Smoke Enforcement Initiative

EPA Voluntary Retrofit Program

CARB Retrofit Advisory Committee

Seattle Diesel Solutions Program

Sacto. AQMD Adopt-A-Bus Program

Forum’s Liaison Role

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 the target audience of users

Onward !

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
