Denver Adds Four Hybrid Trucks to Fleet

News Release

Release date: 06/17/2010

The Denver Fleet Management Division recently replaced older units in its fleet with four Freightliner Business Class M2 106 Hybrid trucks as part of the City and County of Denver’s efforts to decrease energy demands and improve air quality.

One approach to reducing harmful emissions and improving the environment has been the “greening” of Denver’s fleet. The Denver Fleet Management Division, which maintains more than 1,900 vehicles and pieces of equipment for the city, began building its hybrid fleet with the purchase of light-duty hybrids. The four new Freightliner Business Class M2 106 Hybrid aerial bucket trucks will be used for forestry, traffic signal, and traffic sign repair.

“The Freightliner trucks mark our entry into medium-duty hybrid use, and are a welcome addition to our fleet,” said Ernie Ivy, fleet director, City and County of Denver. “With the new trucks, we will improve the way we deliver services to the citizens.”

The Freightliner Business Class M2 106 Hybrid features the Eaton Hybrid Electric parallel Drivetrain System that enables the truck to operate using the diesel engine alone, or in combination with the hybrid electric motor. This provides additional power to launch the vehicle and improve fuel economy in stop-and-go operations, in addition to reducing emissions and operating noise, particularly when the hybrid system powers the auxiliary equipment in ePTO mode, according to the manufacturer.

“We operate in neighborhoods all around Denver, so our goal is to reduce pollution and noise in the places where we live and work,” said Ivy. “The trucks also further our efforts to decrease greenhouse gas emissions and petroleum use.” Denver is receiving grants for the hybrid purchases and should recoup its outlay for the hybrid technology in five to seven years through increased fuel economy and lowered maintenance expenses.

Adams 14 Retrofits Buses to Improve Student and Environmental Health

Release Date: 05/04/2010

Adams 14 has retrofitted 13 District buses with new crankcase filtration systems and engine pre-heaters to reduce idle times, emissions and fuel costs. The results will be healthier students and drivers as well as a cleaner environment while buses take students to and from school.

Thomas Tucker, the district’s lead mechanic, oversaw the improvements, which were made this month through a partnership with the Denver-Based Regional Air Quality Council’s Clean Air Fleets Program, a public-private initiative that helps diesel operators reduce vehicle emissions while saving money. The program receives funding support from the Environmental Protection Agency and the Federal Highway Administration.

“Our newly outfitted buses will have a less detrimental impact on riders and the environment,” Tucker said. As a result of the retrofits, the District should save approximately 1,100 gallons of fuel annually and reduce 12 tons per year of greenhouse gases from the environment including one ton per year of particulate matter, nitrogen oxides, hydrocarbon and carbon monoxide.

Steve McCannon, program manager for the Regional Air Quality Council believes public schools are an important partner. “District leadership and participation has been critical to the success of the program,” he said. “We have been amazed at school districts’ dedication to protecting the health of children.”

Adams 14 is pursuing opportunities to retrofit additional District buses in the future.

About Clean Air Fleets

The Clean Air Fleets program, started in 2003, is a public-private initiative of the Regional Air Quality Council (RAQC) to help on- and off-road diesel operators voluntarily reduce diesel emissions while saving money. To accomplish this goal, Clean Air Fleets:

●   Identifies opportunities and leverages funds from a variety of sources to create effective projects that address the specific needs of 
     Denver Metro Area Fleets.
●   Enables local government and public works, school districts, private, off-road, and over-the-road fleets to install cost-efficient emissions 
     control and idle reduction technologies. 
●   Provides education and outreach assistance to fleet owners and operators about voluntary efforts they can undertake to achieve 
     emissions reductions on their own.


Diesel Conferences and Workshops (2002, 2006, 2009)Working with numerous public and private partners, the RAQC hosted two conferences in 2002 and 2006 and a workshop in 2009 focusing on current diesel-related issues. 

EPA Auxiliary Power Unit Project (2007 – 2008) – The RAQC worked with 9 owners and operators to install 10 Auxiliary Power Units (APUs) on over-the-road semi-tractor trailers to reduce unnecessary idling.

Colorado Retrofit Project (2007-2008) – CORP expanded the RAQC’s retrofit and education efforts to a majority of the school districts and public works fleets in the Denver Metro Area as well as working with a small number of private fleets.

Clean Yellow Fleets for Blue Skies (2003 – 2008) – The first phase of CYFBS was a regional education and retrofit partnership involving 15 local school districts. The CYFBS program successfully installed approximately 1,100 pieces of diesel retrofit equipment on over 800 buses throughout the metro-Denver region and encouraged the use of over 1,000,000 gallons of biodiesel fuel by participating districts. The program additionally implemented “best maintenance practice” trainings and educational outreach to reduce idling.

Diesel Initiative for Retrofit Technology (2003 – 2007) – D.I.R.T. was a small-scale program focused on reducing diesel emissions through the installation of diesel retrofit equipment in off-road fleets working in ‘sensitive’ areas throughout the metro-region. The D.I.R.T. project successfully installed 42 pieces of retrofit equipment on four off-road HDDVs at the City of Commerce City and 17 off-road vehicles at Brannan Sand and Gravel. These retrofits tapped into the off-road construction sector and helped reduce diesel emissions throughout the Northeast Denver area.

Clean Air Fleets Program (2002 – 2005) The original Clean Air Fleets was implemented as a pilot program to educate area fleets about diesel retrofit technologies and successfully installed 69 pieces of diesel retrofit equipment and funded 19 biodiesel grants. The pilot program paved the way to other diesel retrofit efforts by showing project partners the technology was simple and easy to maintain.







Idle Reduction Technologies

Engine and Hydraulic Preheaters

Engine and hydraulic preheaters warm engine fluids to operating temperature to eliminate idling. The units can be installed in tandem with the hydraulic heater to heat hydraulic fluids at the same time. In addition there are options available for in-cab heating. The units provide up to 80% fuel savings compared to idling the engine and significantly reduce engine wear and tear and the need for costly engine rebuilds. These units cost $1,300 – $5,000 depending on a number of factors. Depending on funding availability, the RAQC will install this technology on local government and public works, school district, private, off-road and over-the-road fleet vehicles.

Auxiliary Power Unit (APU)

APU’s provide air conditioning, heating and electrical power for over-the-road trucks to reduce the need for idling. The units provide up to 80% fuel savings compared to idling the engine and significantly reduce engine wear and tear and the need for costly engine rebuilds. APUs cost up to $10,000. Depending on funding availability, the RAQC will install this technology on over-the-road fleet vehicles.

Global Positioning System (GPS)

Installation of GPS tracking units allow fleet management to reduce idling time, fuel usage and streamline routing which can reduce congestion and wasted vehicle operating hours.

Emissions Control Technologies

Diesel Oxidation Catalyst (DOC)

The DOC is a simple muffler replacement that reduces particulates by 20% – 40% and costs $1,000+ depending on vehicle horsepower. Depending on funding availability, the RAQC will install this technology on local government and public works, school district, private and off-road fleet vehicles.

Closed Crankcase Filtration Unit (CCF)

CCFs units close the crankcase through a closed loop system that re-circulates and filter crankcase emissions reducing in-cab emissions and costs $400+ depending on vehicle horsepower. Depending on funding availability, the RAQC will install this technology on local government and public works, school district, private and off-road fleet vehicles.

Diesel Particulate Filter (DPF)

The DPFs are muffler replacements that provide 90% emissions reductions. The units require periodic maintenance and the use of ULSD fuel. DMFs cost $9,000+ depending on vehicle horsepower. The technology can be installed on local government and public works, school district, and private fleet vehicles.

New Vehicles

Diesel/Hydraulic Vehicles (HLA)

The EPA has developed an innovative new hydraulic hybrid system to provide cost-effective, ultra-clean and efficient vehicles.  This new hybrid system provides “launch assist” by capturing most energy lost during braking and uses it to propel the vehicle after its next stop.

Plug-in Hybrid Electric Vehicles (PHEV) and Electric Vehicles (EV)

Electric and plug-in hybrid electric vehicles are fueled by electricity that comes directly from the power grid. While running on electricity, these vehicles produce zero tailpipe emissions. Depending on funding availability, funding is focused on those entities not eligible for the state income tax credit.


Electric Vehicle Supply Equipment (EVSE)

Electric vehicle charging stations provide electricity to plug-in hybrid electric and all electric vehicles. Depending on availability, the RAQC will assist public and private entities with funding for Level 2 and Level 3 charging stations.
