Green tires effectively reduce carbon dioxide emissions from cars

the tire industry and its suppliers have been committed to reducing carbon dioxide emissions from road traffic. Research shows that the fuel consumption caused by tire rolling resistance accounts for% of the total fuel consumption of passenger cars, that is, 1/4 of the fuel tank capacity. In urban traffic and trucks, this figure is even as high as 30%

rolling resistance regulation

the above facts prompted the European Commission to propose a regulation to force the automotive industry to adopt low rolling resistance tires. As a result, the R & D Department of tire manufacturers has begun to strive to reduce the rolling resistance of their products to the greatest extent, so as to gradually reach the carbon dioxide emission level per kilometer of passenger cars stipulated by the European Union by 2015. The proposal of the European Commission predicts that by reducing rolling resistance alone, carbon dioxide emissions per kilometer of passenger cars can be reduced by 7 grams. These regulations will force cars to install tire pressure monitoring systems

a statement issued by the European Union on May 23, 2008 said: "Low rolling resistance tyres must be used in 2012. This kind of tyre can produce less deformation when rolling, so it can reduce fuel consumption. Rolling resistance largely depends on the material of the tyre, and the rolling resistance can be reduced by adding silicon dioxide to the tread material. While reducing rolling resistance, it will not affect other important properties, and the requirements for wet grip and rolling noise will also be specified."

when the tire deforms to contact the road as much as possible, the medical equipment innovation and development of the tire speed-up rolling resistance (usually calculated in kilograms/ton) will occur, and ultimately affect the traction. Whenever the tire rolls and cushions on the road, it will absorb energy, convert the absorbed energy into heat, and release it into the atmosphere. The greater the energy consumed by friction and deformation, the tighter the tire tread grasps the ground, and the less air in the tire. For tire manufacturers and their suppliers, this means that they must find appropriate ways to reduce friction without sacrificing safety and grip under wet noodles

the world's leading rubber suppliers actively develop and provide innovative solutions to the market demand for green tires. High performance rubber materials from LANXESS can help tires reduce rolling resistance. The world's leading manufacturer of synthetic rubber and rubber chemicals is committed to using innovative technologies to help energy-saving tires enhance safety and prolong service life. Solution polymerized styrene butadiene rubber produced by LANXESS is used as tread compound of high-performance tires, which can reduce rolling resistance and improve grip performance on wet roads. Neodymium butadiene rubber used in tire compound is superior to many other tire rubbers in reducing energy consumption. In addition, it can also reduce tire wear, so it plays an important role in improving vehicle safety, environmental protection and economy

data show that high-performance "green tires" are the fastest-growing areas of the tire industry, with an annual global growth rate of about 9%

reducing tire rolling resistance can significantly reduce vehicle fuel consumption, and the EU has formulated corresponding mandatory low rolling resistance tire regulations

appropriate air pressure, benefit the climate

the "smart" tire with sensors inside the tread can inform the driver when the tire needs to be inflated. Even if the air pressure is only 0.3 bar lower than the manufacturer's recommended value, the rolling resistance will increase by 6% and the vehicle's fuel consumption will increase by about 1.5%. For standard size cars, the fuel consumption will increase by about 16 liters per year. According to the calculation of a well-known German tire manufacturer, this will cause each vehicle to emit 38 kilograms of harmful carbon dioxide every year. At first glance, this figure may not be so shocking, but if we connect these statistics with about 33% of Germany's vehicles with insufficient tire pressure (15.2 million vehicles), based on the vehicle fuel consumption of 7.5 liters/100 kilometers and the annual driving mileage of about 15000 kilometers, carbon dioxide emissions will increase by more than 344 tons of wallpaper hazardous materials every year

from the figures released by the European Union, we can visually see the impact of insufficient tire pressure on the environment: statistics show that if a car's tire under pressure is only 0.5 bar, the annual increase in carbon dioxide emissions will be as high as 140 kg. If the tires of all vehicles in Europe reach the correct pressure, the fuel consumption and carbon dioxide emissions can be reduced by 2.5%

for multi-function vehicles, if the tire pressure reaches the optimal level, the potential to reduce fuel consumption and carbon dioxide emissions is the greatest. A study conducted in the United States found that the average under pressure rate of multi-function vehicle tires is about 12%, which will increase the gasoline consumption by nearly 4billion liters every year, resulting in more than 9 billion tons of unnecessary carbon dioxide emissions. Checking the air pressure regularly can not only reduce carbon dioxide emissions, but also reduce the fuel cost of drivers

lucent halogenated butyl rubber is mainly used to produce the innermost liner of tubeless tires. Its gas and water permeability is extremely low, which can keep the tire pressure stable for a long time. This feature not only improves the safety of the vehicle, but also ensures that the vehicle reduces fuel consumption, thereby reducing harmful gas emissions. With the continuous growth of radial tire production capacity in Asia, the market demand for halogenated butyl rubber is becoming stronger and stronger

sensitive electronic device

most drivers go to the gas station just to refuel. They may also check the oil level and water level, but rarely think of checking the tire pressure. Therefore, some leading tire manufacturers are developing a new generation of tires equipped with electronic tire pressure monitoring system. The sensor module weighing only a few grams is installed inside the tread of the "sensitive" tire and connected to the vehicle's electronics. These sensitive "passengers" will transmit relevant data such as tire type, air pressure, speed and load index to the on-board computer, so as to make ABS (anti lock braking system), ESP (Electronic Stability Program) and other auxiliary systems play a more effective role

in the future, the on-board computer will provide wheel and axle load distribution data to the microchips of ABS and ESP at the beginning of the journey, making driving safer and more comfortable. In the near future, at the beginning and end of the journey, when the vehicle is loaded and unloaded, the tires will "notify" the driver to adjust the inflation pressure. The sensors on each wheel can automatically detect the tire load and give an alarm when the position of the goods on the truck changes

there are many ways to reduce carbon dioxide emissions from cars, and using green tires is a very important way

encouraging figures

tire manufacturers also see the great potential of rubber compound optimization and tire structure improvement in protecting the environment and minimizing fuel consumption. The measures taken include not only the use of silicon enclosed in the box for dioxygen temperature calibration as the filler, and the use of mixtures of different kinds of rubber, but also the tread design, belt and carcass composition of the tire. Although leading tire manufacturers have reduced rolling resistance by 30% in the past 15 years, researchers note that there is still more room for progress. Tire manufacturers plan to reduce rolling resistance by 50% in the coming years. This will greatly reduce the total amount of harmful gases emitted into the atmosphere. People are working hard to halve the fuel consumption caused by rolling resistance. The saved fuel consumption will be increased from the current equivalent of 1/8 of the fuel tank capacity to equivalent to 1/4 of the fuel tank capacity

through the following data provided by experts, we can more vividly understand the positive impact of "green" tires

example 1: if all cars and trucks in Europe are equipped with modern low rolling resistance tires, they can save 4.5 billion liters of diesel and 1.5 billion liters of gasoline every year. This will mean reducing carbon dioxide emissions by about 15million tons

example 2: if all passenger cars use the best low rolling resistance tires on the market, the global carbon dioxide emission will be reduced by about 50million tons. The average fuel consumption of medium-sized vehicles can be reduced by up to 0.3 liters per kilometer. Based on the average service life of vehicles, each vehicle will reduce about 1200 kg of carbon dioxide emissions

set a good example

although various signs show that some progress has been made in reducing fuel consumption and carbon dioxide emissions, automobile manufacturers, suppliers and partners in the chemical industry need to work together to achieve the future vehicle carbon dioxide emission standards set by the EU, working towards the same goal, that is, while ensuring unrestricted mobility, Curb global warming and its possible huge impact on the environment

to help achieve these goals, car buyers will need to switch to "green" tires. Regulation is essential, but persuading people to take action is preferable. F-1 is setting a good example in this regard: as part of the "green driving" activities of the International Automobile Federation, cars have begun to use environmentally friendly tires since the 2008 Fuji Grand Prix in Japan. In addition, since the 2009 season, the FIA has also introduced an energy recycling system to deal with the energy generated during braking. The technological progress of top models in the automotive industry has been increasingly applied to ordinary cars. "Green" tyres are no exception
