Reducir la contaminación causante del calentamiento global: Opciones tecnológicas para los tractocamiones

The document outlines how heavy-duty trucks, particularly long-haul vehicles, contribute significantly to global warming emissions, specifically in California. It details aerodynamic improvements for tractors and trailers, as well as tire-related strategies to reduce rolling resistance, noting that these combined technologies can significantly lower fuel consumption and costs.

• Heavy-duty trucks are a major source of emissions in California, where they consume over 3 billion gallons of diesel and account for 7.5% of the state's total global warming pollution.
• Aerodynamic designs for tractors—including low-profile mirrors, roof and fuel tank fairings, rounded bumpers, and hidden exhaust pipes—can reduce fuel consumption by 15% to 20% compared to 'classic' style trucks.
• Trailer aerodynamics can be improved using side skirts, front fairings to reduce the gap between the tractor and trailer, and tail fairings to reduce rear resistance; combining these with low rolling resistance or wide single tires can improve overall fuel performance by up to an additional 10%.
• Rolling resistance accounts for approximately 15% to 33% of a heavy-duty truck's fuel consumption. This can be mitigated through low rolling resistance tires, wide single tires (which reduce weight and improve aerodynamics), and automatic tire inflation systems, the latter of which the EPA estimates can increase fuel performance by up to 0.6%.
• The US EPA's SmartWay program helps truck owners identify new equipment and retrofitting devices that meet specific performance criteria for air pollutant emissions and fuel efficiency.
