Michelin Green tires have significant energy-saving effects

"since Michelin launched the first fuel-efficient truck and bus tire in China in 2006, we have done a lot of tests with users, but we still need a more authoritative organization to prove the fuel-saving performance of Michelin tires. In June this year, Michelin conducted a tire fuel-saving test at the official authoritative test site, the road traffic test site of the Ministry of communications. The minimum temperature can reach ⑴ 90 ℃ (⑴ 90 ℃ ~ ⑴ 96 ℃ are special requirements) the test results are very encouraging. Compared with ordinary tyres, Michelin can save 3.8% fuel for passenger car tyres with inner tubes and 4.5% fuel for passenger car tyres without inner tubes. " Zhanghongbing, customer experience manager of the truck and bus tire Department of Michelin (China) Investment Co., Ltd., recently said at the media exchange meeting on fuel saving test of Michelin truck and bus tires that energy conservation and emission reduction are important measures for China's sustainable economic development. What Michelin needs to do is to give full play to its advantages and constantly develop fuel-saving green products that can meet market demand

reduce the cost for the fleet

zhanghongbing said that the fuel cost accounts for more than 40% of the total operating cost of the Chinese fleet. It is reported that the current high oil price has caused great cost pressure on the operation of the transport fleet. In this case, how to save fuel is very important for the truck and bus operation unit. For the transport fleet, some costs are unavoidable, such as driver salary, road maintenance fee, depreciation fee, insurance premium, bridge crossing fee, etc., but some costs are controllable, such as vehicle maintenance, purchase of tire and other parts, and fuel cost. If enterprises choose fuel-efficient tires, they can really reduce costs

according to the test results of Michelin tires at the highway traffic test site of the Ministry of transport, based on the annual normal driving of about 200000 kilometers, the average fuel consumption of 35 liters per 100 kilometers and the current diesel price of 7.5 yuan/liter, the annual fuel cost saved by each vehicle after installing Michelin fuel-efficient tires is about 21000 yuan, which is equivalent to the price of 67 Michelin tires. If it is a transport fleet with 50 vehicles, 1.05 million yuan can be saved every year. "Under such fierce competition, it is very tempting for an operating team to save so much cost through tyres." Zhanghongbing said

"this does not add to the overall benefits of retreading tyres." According to zhanghongbing, Michelin now also provides fuel-efficient tire tread. The Mi-1 Qilin tire can have multiple lives. The grooved tire can increase its life by 25% and can be refurbished twice, bringing more significant comprehensive fuel-saving effect. He said that compared with the fuel cost accounting for about 40% of the automobile transportation cost, the tire cost accounts for about 6% of the whole vehicle transportation cost. The comprehensive fuel saving and cost reduction effect of using fuel-efficient tires is considerable

optimized design for reducing rolling resistance

then, where does the fuel consumption go on the high-speed truck and bus? Michaelblanc, product marketing manager of the truck and bus tire Department of Michelin (China) company, introduced that it takes 40% of the fuel to overcome the wind resistance, 25% to overcome the internal mechanical resistance, and 35% to overcome the tire rolling resistance. Michael said that the rolling resistance of the tire comes from the force generated by the friction of various parts inside the tire, which makes the tire generate heat in the process of movement and deformation, thus consuming fuel. Therefore, reducing the rolling resistance is of great significance to tire fuel conservation

Michael said that Michelin could reduce the tire energy consumption by improving the compound formula and replacing carbon black with white carbon black, while optimizing the carcass structure design and pattern design to reduce rolling resistance. "We have obtained a set of data. Every 5% reduction in rolling resistance can save 1% of fuel. Although different vehicles and different uses have different effects, the proportion of reduction in rolling resistance and fuel saving effect is certain. In addition, it should be emphasized that we reduce rolling resistance without affecting the grip of tires to help truck and bus users save money." Michael said

improved market acceptance

zhanghongbing said that energy conservation and emission reduction is an important national policy during the "12th Five Year Plan" period, and also the development direction of the automotive industry in the future. Automobile manufacturers should research and develop engine and other parts to save fuel, and parts manufacturers should also consider how to save energy. "Since Michelin developed the green fuel-efficient tire in 1992, it has been constantly innovating. By improving the tire formula design, it can reduce the rolling resistance of the tire and achieve the goal of saving fuel. Now many automobile manufacturers are interested in Michelin fuel-efficient tires. Fuel-efficient tires are very helpful for automobile energy conservation. Under the current environment in China, whether it is the government policy, the demand of the automobile industry or the cost control of the transportation fleet, fuel-efficient tires All of them are of common concern to meet the energy-saving needs of users to the greatest extent. " Zhanghongbing said

according to zhanghongbing, Michelin and customers have jointly conducted 20 different fuel saving tests this year. Customers are very interested in this because they also want to verify how much the tire cost can be reduced. Among them, the use report from Henan Zhengzhou Panther transportation company shows that the comprehensive fuel saving effect of using Michelin fuel-saving tires is 3.6%; After using Michelin fuel-efficient tires, Hangzhou Lin'an Guang'an cargo transportation Co., Ltd. saved about 10 yuan of diesel per 100 kilometers... "These tests give us confidence and give the team specific fuel-efficient concepts. We hope to promote the fuel-efficient concept to users, so that customers can really feel the benefits." Zhanghongbing said that at present, some large domestic commercial vehicle manufacturers have become interested in Michelin fuel-efficient tires, and in the future, models with original Michelin fuel-efficient tires will appear one after another

it is understood that since Michelin launched the first xza2+ energy-saving truck and bus tire in China in August, 2006, it successively released x coach XZ energy and xda2 energy/xda2+ energy series truck and bus fuel-saving tires in August, 2010 and March, 2011. Zhanghongbing said that at present, whether trucks or buses, Michelin's fuel-efficient tire product series with and without inner tubes can meet the needs of the Chinese market. Michelin has accounted for 1/4 of the sales of fuel-efficient tires in the Chinese market, and its market acceptance is getting higher and higher

zhanghongbing said that from the launch of the first fuel-efficient tire in 1992 to October 10, 2011, Michelin tires saved 14.6 billion liters of fuel and 36.7 billion kg of carbon dioxide emissions worldwide
