Measured results tires Lanxess energy supplier RheinEnergie jointly completed by the company shows that the traffic situation in the city, the "green tire" can save up to 7% of fuel consumption (average decrease of approximately 4.1% of the fuel consumption), and enables fleet operators annually Suppliers save thousands euros.
In the EU tire labeling system, the fuel efficiency "C" above the level of carbon dioxide emissions than the standard high-performance tires tires dropped significantly.
LANXESS AG management board member 卢塞尔 said: "After this long-term test, we confirmed the high-performance tires in use not only for fleet operators, but also for individual significant cost savings in addition, 'green tires' also. made important contributions to environmental protection. "
For example, if all registered 442,013 diesel and petrol vehicles in Cologne, Germany with lower rolling resistance B class "green tires" Replace F-class tires, traveling 14,000 km per vehicle on average, then the year will likely Cologne save 19.8 million liters of fuel consumption and reduce carbon dioxide emissions by 48,000 tons. This means that the use of "green tires" to offset carbon dioxide emissions by more than 18,000 Cologne cars.
Another example is fully illustrated using the "green tire" can bring economic benefits to fleet operators. A car has a 650 or 3.5t truck fleet is replaced with the EU tire labeling system rolling resistance tires Class B Class F tires, assuming vehicle traveling 14,000 kilometers, the oil price € 1.35 / liter, then the team and one can save nearly 44,500 euros, carbon dioxide emissions will be reduced by 87 tons.
During the experiment, the experimental group to monitor the same models RheinEnergie six cars in half the fuel consumption, and compared the "green tire" and the standard tire gap in terms of fuel consumption. Experimental vehicle weighs about two tons, traveling during the experiment in the city of Cologne and the surrounding areas, routes, drivers, truck and fuel conditions exactly. After the test, the total of all vehicles travel over 37,000 kilometers.
To ensure the validity of experimental results, the experiment was divided into two phases. In the previous three months, the first group of three vehicles equipped with a "green tire" (EU tire labeling system rolling resistance Class B), and three vehicles with standard tire group 2 (EU tire labeling system rolling resistance F level). After three months, the two groups of vehicles tire swap. The results indicate that the "green tire" save fuel consumption by up to 6.96%, while the carbon dioxide emissions can be reduced up to ten thousand kilometers per 155 kg.
EU on 1 November 2012 to begin a new tire labeling law enforcement. The regulations apply to all vehicles tires, including private cars and light and heavy commercial vehicles. The label on the tire rolling resistance (ie fuel consumption) into Class A (low rolling resistance) to G grade (high rolling resistance). Tab also displays information about the tire wet grip (safety) and rolling amount of noise. "Green tire" in the EU label rating is very high.
