The United States is known as the "country on wheels," and it ranks not only in terms of vehicle ownership and utilization, but also leads the world in terms of energy conservation, emission reduction and emission standards for automobiles.
In the United States, truck transport carries the main function of road logistics transportation. According to statistics, heavy trucks carry 70% of the U.S. materials, but they also consume about 80% of the U.S. diesel. Therefore, the control of fuel consumption for trucks is crucial for the United States to save logistics costs and petroleum resources.
In 2009, the U.S. Department of Energy announced that it will invest 270 million U.S. dollars in 2010-2015 to develop a new generation of trucks that are 50% lower than the current truck fuel consumption, namely the "Super Truck" program. In order to achieve this goal, the U.S. Department of Energy will cooperate with some of the world’s leading truck manufacturers and engine manufacturers to jointly invest in innovative research on important areas of engine technology and vehicle technology, aiming to reduce the fuel consumption of existing trucks by 50. %, the emission standard is higher than the Euro V standard implemented in Europe.
On February 13th, Dr. Lei Ning, technical fellow of the Navistar Powertrain Product R&D Center, introduced the United States at a media conference with the theme of “New Power, Yuelong Year†held by the United States Navistar Corporation in Beijing. The "super truck" program.
It is understood that U.S. companies participating in the "Super Truck" program include international leading vehicle and engine companies such as Navistar, peterbilt, and Cummins. Of the 270 million U.S. dollars in R&D expenses, the U.S. Department of Energy assumes 45%, and the rest is shared by R&D companies. In the 50% reduction target, vehicle technology innovation accounts for 60%, and engine technology accounts for 40%.
Renin also said that Navistar was designated by the US Department of Energy as one of the "super truck" cooperation companies. According to the agreement between the two parties, the U.S. Department of Energy, Navistar, and its supplier partners will invest US$37 million and US$52 million respectively in research funding, focusing on innovations such as truck aerodynamics, engine combustion efficiency, waste heat recovery, and hybrid power. Sexual research. "In terms of vehicle technology innovation, we will focus on aerodynamics, light weight, transmission systems, and hybrid power. In terms of engines, we will examine waste heat recovery, combustion systems, air-fuel ratio, engine structure and control, etc. The focus of the study." Lei Ning further explained.
Speaking of the current progress, Lenin said that according to their plan, in the first year, that is, in 2010, they planned the entire project, set up simulation experiments for various technologies, and conducted cost control and feasibility analysis. In the second year, various experimental projects have already started, and some results have already come out. "So far, under the efforts of researchers, Navistar has made progress in several areas of research and achieved the desired target. Achieving significant breakthroughs in engine technology and aerodynamic optimization. Navistar and the Ministry of Energy renewed the contract between the two parties and will continue to work hard to achieve the goal of reducing fuel consumption for trucks, said Lei Ning.
The head of the U.S. Department of Energy’s “super truck†also stated earlier this year that research on the “super truck†program is progressing well. Although the goal of reducing fuel consumption is very challenging, the current projects are all on schedule according to the previously specified schedule.
