When you enter certain areas in which even the smallest of them has an unimaginable role, you need to be prepared for everything. open the door for Pollution assessment The one thing that makes up modern human life, is to put a magnifying glass on every act, and to go far beyond the use of the car. If only the amount of plastic each person consumes and the waste, and the environmental damage it causes, can be quantified, we would all panic.
But confined to the world of cars only, Paying a lot of attention to each vehicle’s CO2 emissions was a right decision, as it marked the beginning of sustainable mobility. This, in turn, has enabled many Other parallel studies have focused on other types of pollution which can generate a car.
truly, The great debate that is taking place at the present time between manufacturers, governments and consumers is precisely How polluted is an electric car? If it is charged with energy that is not generated from renewable sources such as wind or solar energyInstead it is obtained through gas-fired plants, like most plants that generate electricity around the world.
There is another question that needs a different answer because it is a complete topic with many opinions but some certainty, and this is it The future pollution of electric car batteries when they can not be used And you have to get rid of it.
for several months, European Commission delay entry Euro 7 . standard Because a new obstacle has appeared entirely before the agenda, and that is what we have to do now. Car brake system pollution assessmentAnd the Here is an uncomfortable situation for defenders electric car In time, because some studies indicate that Heavy vehicle due to battery which is part of its motive form, With each stroke, more polluting particles are emitted Compared to cars with internal combustion engines.
The presence of fine black powder accumulating on the skin can only be checked by practicing crossing a finger across the front tire of a vehicle. Vehicles can be expelled six times more polluting particles Where The braking system compared to the exhaust system, which accounts for between 12.5% to 21% of the total emissions of traffic vehicles.
How its effect can be resolved or reduced is a question. The first thing that comes to mind is to change the brake lining compound to materials that are less harmful to health., but while this is happening, the idea of an assembly system for these particles is also under study. The idea is to generate a type The vacuum cleaner sucks up the dark-colored dust that comes out with every brakeLike the internal combustion engine filter, it must be changed periodically. What is done with these filters next is another problem that needs to be solved.
But if the brakes are worrying environmental officials, now a new player is approaching: tires. To many, it may seem like a minor problem, but it’s a recent study Emission AnalyticsPublished by a British daily newspaper, a leading independent emissions testing company guardianwarn about it Tire wear results in approximately 2,000 times more particulate pollution than the exhaust pipes of modern cars.
And again, the weight of the car determines the amount of particles that are released due to the wear of its soft parts. Just as friction wears down the brakes, so does the tires, the heavier a car is, the more friction it needs to move and stop.
“We encounter a huge amount of material being released into the environment – 300,000 tons of tire rubber from cars and pickups every year in the UK and US”said Nick Molden, an analyst at the consulting firm that conducted the study.
a. Tire wear tested on 14 different brands using Mercedes C-Class They were generally driven on the road, and some were tested throughout their lives. High-precision scales measure lost weight from tires and a sampling system that collects particles behind tires while driving Particle mass, number, and size up to 6 nanometers (nm) were evaluated. comparison, Using the 2019 and 2020 models, exhaust emissions were measured in four of today’s most popular new cars, and four gasoline-powered SUVs.
The tires produced 36 mg/km of particulate matter, which is 1,850 times more than the exhaust pipe average of 0.02 mg/km. And if the driving style is too aggressive in terms of braking and cornering speed, despite always adhering to traffic rules, particulate emissions from tires Increased up to 5760 mg/km.
But in addition to the air, tire mites also pollute water and soil and contain a wide range of toxic organic compounds, including known carcinogens. Analysts say so Tire pollution can quickly become a major problem for air pollution control officials. all over the world.
As for brake contamination, the reducing agent in electric vehicles is likely to be the energy regeneration system, which allows the driver to get away from the mechanical brake pedal with the electric motor’s brakes by changing its polarity. Some systems like Nissan E-pedalHe went above and beyond in his operation because By using the accelerator pedal, you can also control when the braking intensity is reducedTo the point of stopping the car completely.
Perhaps this is a solution that can be widely integrated, and In this case, it will only be necessary to solve the tire consumption problemAs the output appears to be related to more compound used to makeThan any other way to reduce an element It will inevitably degrade with use and generate waste in the process.
