U.S. Develops New Fuel Emission Standards for Medium/Heavy Vehicles

Comprehensive media reported recently that the U.S. government announced on October 25 a new fuel emission standard that aims to significantly increase the fuel use efficiency of medium/heavy vehicles to address the large fuel consumption and pollution caused by these vehicles. Severe and other issues are expected to begin in 2014 and will be valid until 2018. The introduction of this standard is yet another meaningful step following the implementation of the 2012-2016 fuel emission reduction standard for light vehicles such as cars in April this year, as part of the development of a new generation of clean and efficient automobiles in the United States. Not only does it set strict boundaries for the fuel standards of large vehicles, it also contributes to reducing air pollution.

The report said that the standard for large vehicles was jointly announced by the National Highway Traffic Safety Administration and the Environmental Protection Agency. Both parties stated in a statement that this is the nation’s first national standard for greenhouse gas emissions from trucks and buses, which will set different emission reduction standards based on weight and use. By 2018, large-scale trucks and other engineering vehicles need to meet the target of fuel consumption and carbon emission reduction by 20%; heavy-duty trucks and vans need to reach the target of 10%-15%; other large-scale vehicles such as buses, RVs, and garbage. Cars, etc. must also achieve a goal of at least 10%.

Energy-saving regulations have been extended to heavy-duty vehicles. In fact, the establishment of emission reduction standards for heavy-duty vehicles has long been foreseen. In May of this year, the Obama administration signed a landmark agreement that for the first time gave the Environmental Protection Agency and the National Highway Traffic Safety Administration the power to set fuel efficiency standards for medium/heavy vehicles, prompting both parties to complete this together. Standard initial regulations. Obama said: "I believe that in the next 20 years, this standard will help reduce the environmental pollution caused by trucks by half."

Although it is the first time that fuel standards have been set for heavy vehicles, it is clearly a continuation of the government's standards for cars. However, this standard has mainly borrowed from the research of the National Academy of Sciences this year, which focuses on existing technologies, including low rolling resistance tires. , Improved aerodynamics, more efficient engines, hybrid electric drive systems and idle speed control, which can reduce heavy truck fuel consumption by 1/2. Lisa Jackson, the director of the Environmental Protection Agency, said that for heavy-duty drivers, the cost of reducing fuel is far lower than the use of technical means to meet the new standards. At the same time, it can bring heavy truck manufacturing and related industries. job opportunity. At a press conference, she said: “By reducing engine idling, installing improved tires, air conditioning and transmission systems, heavy-duty vehicles can basically meet their goals, and those heavy-duty companies can do just by changing the way their vehicles are driven and maintained. To this point."

In addition, she added that measures can save fuel costs of about 75,000 U.S. dollars for heavy vehicles within the service life of a vehicle. Overall, this standard will save the U.S. government $41 billion. “Saving more fuel can reduce the cost of fuel for small businesses that rely on trucks and heavy vehicles, transport companies, and towns that own these vehicles. These savings can be invested in new jobs in the country instead of Turning overseas increases our dependence on foreign oil."

U.S. Secretary of Transportation Ray Lahoud also publicly stated that the new standard will create a “win-win-win” situation, even if the U.S. industry, truck drivers and consumers, and the environment will benefit from the three aspects. He estimated: "After the adoption of the new standard, it will save 500 million barrels of oil for various new vehicles from 2014 to 2018 and reduce 250 tons of greenhouse gas emissions during the entire service life of heavy vehicles."

It is of great significance to solve air pollution According to a survey report of the Union of Worried Scientists, a non-profit organization in the United States, the Union of Worried Scientists, the heavy vehicles involved in this standard are only 4% of all vehicles in the United States, but their consumption of gasoline accounts for For 20% of all vehicles, such as tractors, the fuel consumption is basically 6.5 miles per gallon. Obviously this standard is of great significance for solving atmospheric pollution.

Not only that, but also measures such as saving fuel are not a small expense. The American Trucking Association is a trading group based in Arlington and Virginia, with 37,000 truck companies joining the group. Bill Graves, CEO of the association, said: "This standard is very flexible and can be achieved through existing technologies." He calculated that with the introduction of this standard, it will cost about $7.7 billion for engines. , Tire power upgrades and other work. It is estimated that by the end of the life of a vehicle, the total savings saved by saving fuel, reducing exhaust emissions, and reducing noise will amount to $49 billion.

The United States Natural Resources Defense Council, a Washington-based environmental organization, also praised the standard and believed that stricter regulations can be implemented. Luke Tonerkeller, an analyst at the committee, said in an interview: “This is a historic standard. Heavy-duty vehicles are the big guy on the road to the development of U.S. energy, with more energy-efficient engines, streamlined bodies and more. Clean fuel, our truck fleet can be driven in a cleaner and more economical way. The new standard will save truck owners and consumers money, and in the process create job opportunities and reduce pollution."

The proposal involving truck energy efficiency standards is part of the US environmental protection plan. The plan also includes the promotion of energy-saving cars, light trucks, and reduction of carbon emissions. It will publicly solicit comments within the 60-day public comment period, but it is not expected to Made major changes because representatives of the industry and other relevant parties have already provided their feedback.
