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)
APUs 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 Multi-Stage Filter (DMF)
DMFs are muffler replacements that operate similar to particulate traps but require no maintenance and achieve 75% particulate reductions. The units require the use of ULSD fuel and cost $6,000+ depending on vehicle horsepower. DMFs can be installed on local government and public works, school district, private and off-road fleet vehicles. Depending on funding availability, the RAQC will install this technology on local government and public works, school district, and private fleet vehicles.
Diesel Particulate Trap 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. The RAQC is currently not offering this technology. Check back soon for program developments.
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.
Aerodynamic Improvements
Low Rolling Resistance Tires (LLR Tires)
Based upon data provided by tire manufacturers and EPA testing and research, EPA determined that certain low rolling resistance tire models can provide a reduction in NOx emissions and an estimated fuel savings of 3% or greater, relative to the “best selling” new tires for line haul trucks, when used on all five axles on long haul class 8 trucks.
The Clean Air Fleets program is a regional public-private initiative to educate on- and off-road diesel vehicle operators on how to voluntarily reduce diesel emissions while saving money.
