What is SmartWay verified?

The SmartWay Verification Program evaluates the ability of LRRs to reduce resistance and improve fuel economy or emissions for Class 8 tractor-trailers.

What is a SmartWay semi truck?

EPA-designated SmartWay Tractors and Trailers are long-haul freight vehicles that significantly lower fuel consumption and emissions of air pollutants. These tractors and trailers have been tested and validated to ensure top performance.​

What is SmartWay certification based on?

Earning SmartWay Certification SmartWay certification is based on the greenhouse gas (GHG) and smog ratings found on vehicle fuel economy labels.

What is a SmartWay tire?

SmartWay is an EPA program that reduces transportation-related emissions. Launched in 2004, SmartWay creates incentives to improve supply chain fuel efficiency. Verified Low Rolling Resistance Tires.

What is US EPA Certified SmartWay?

EPA’s SmartWay program helps companies advance supply chain sustainability by measuring, benchmarking, and improving freight transportation efficiency.

What is EPA SmartWay certified?

What are SmartWay Certified Vehicles? Each model year, EPA rates every new car, truck, and Sport Utility Vehicle (SUV) for greenhouse gas and smog-forming emissions on scales of 1-10. To earn the SmartWay designation, a vehicle must receive a combined score from both scales that is much better than the average vehicle.

How do you calculate rolling resistance?

Note 1: Rolling Resistance Coefficient μR is defined by μR = F/G, where F is the force necessary to pull the axle of a tire horizontally in the direction of travel, and G is the vertical load on the tire which is assumed to roll on a flat horizontal surface.

How do I join the SmartWay?

What is a SmartWay score?

THE SMARTWAY TRANSPORT PARTNERSHIP, the Environmental Protection Agency’s program to help companies use the newest trucking technology to cut fuel usage and emissions, has a number of food retailer participants.

What are two factors that affect rolling resistance?

WHICH FACTORS AFFECT ROLLING RESISTANCE? Tire pressure, tire diameter, tire width, tire construction, tire tread and other factors all have an effect on rolling resistance.

Does weight affect rolling resistance?

Extra weight causes a greater deformation of the sidewalls and tread of a tire, thus, increasing the rolling resistance. Rolling resistance increases in direct proportion to the weight that the wheel supports, and is equal to about 0.3 to 0.5 percent of the load on the wheel.

How do you reduce rolling resistance?

One way to reduce rolling resistance is to increase air pressure in your tires to the recommended amount. With increased tire pressure, the tire ends up getting less deformed while going down the road, resulting in less energy wasted.

How do you increase rolling resistance?

Mass – more mass means more downwards force due to gravity onto the road. This results in more tyre compression so rolling resistance increases. Carrying things like extra water bottles increases your rolling resistance.

Why are lighter bikes faster?

Heavier wheels require more energy to overcome this inertia. Many riders, even novices, can feel the difference when riding lighter wheels. They make a bike feel snappier and easier to accelerate.

Does rolling resistance increase with speed?

The force of rolling resistance does not change at higher speeds. However, because there is a lot more heat being produced at higher speeds, the cyclist uses more power (energy per second) to work against rolling resistance.

Do wider tires reduce rolling resistance?

As discussed in our guide to road bike tyre pressure, wider tyres at lower pressures can help keep the rubber in contact with the road more of the time, leading to lower rolling resistance.

Does a carbon bike make you faster?

However, a small experiment conducted recently by Cycling Weekly demonstrated that a cyclist generating 200w of pedalling power on an aero carbon bike was 1.7kph faster than on a lightweight carbon bike – extrapolated over four hours riding they claimed this would translate into an extra 6.6km distance travelled.

Is 10kg heavy for a road bike?

An average entry- to mid-level road bike will weigh around 20-25 pounds (9.1-11.3 kg).
