trucks_volvo  
Volvo
Volvo Trucks North America’s D11 and D13 engines have been certified by the U.S. Environmental Protection Agency and the California Air Resources Board as meeting 2010 diesel emissions standards, the most stringent in the world.

Volvo is the first truck manufacturer to have its heavy-duty diesel engines certified for 2010 by both EPA and CARB.  These engines have been fully certified to meet EPA’s stringent standards without the use of emissions credits.

Volvo Trucks’ emissions technology for EPA2010 does more than cut emissions of nitrogen oxides (NOx) and particulate matter (PM) to near-zero levels.  Using selective catalytic reduction (SCR) to reduce NOx, Volvo improved fuel economy and reduced emissions of the greenhouse gas CO2.  SCR also helps eliminate active regenerations of the diesel particulate filter (DPF), which saves additional fuel.

All heavy-duty diesel truck engines produced after January 1, 2010 must meet the new standards.  Volvo has extensive experience with SCR technology, having accumulated eight million kilometres with 50 test vehicles in customer field test fleets in North America, as well as billions of kilometres of real-world experience with SCR in other markets.

trucks_mack  
MACK
A MACK® Granite™ diesel-electric hybrid tractor built by Mack Trucks, Inc, represents the latest generation of heavy-duty hybrid technology and meets the near-zero EPA2010 emissions regulations.

The Granite model diesel-electric hybrid powertrain features an integrated starter, alternator and electric motor.  The system captures energy from braking in the form of electricity, stores it in a 630-volt lithium-ion battery pack, and uses it to power the electric motor, which assists the MACK MP7 diesel engine with propulsion of the truck.

Mack’s hybrid technology demonstrates as much as a 30 per cent fuel economy improvement, depending on the truck’s application. The tractor powertrain also provides electrification, allowing it to operate as a mobile power station.  The battery is equipped with electrical outlets for computers, lighting or equipment with 110 volt, 220 volt and 3-phase current available.  The Granite tractor is also equipped with selective catalytic reduction (SCR) emissions control system to comply with the stringent EPA 2010 emissions limits for nitrogen oxides (NOx).  SCR also delivers improved fuel economy and lower operating costs.
