The European Union has been a leader in setting strict emission standards to combat environmental pollution and climate change. The automotive industry is now facing another transformation with the introduction of the Euro 7 emission standards, which will impact the brakes of passenger cars, vans, trucks, and buses. Although regulations typically focus on engines and exhaust systems, it is important to note that all vehicle components contribute to emissions, including the brakes. This article explores the impact of Euro 7 regulations on the brake systems of passenger cars, vans, trucks, and buses.
NON-EXHAUST EMISSIONS (NEE)
Although exhaust emissions are the most obvious pollutants, it is now acknowledged that a significant percentage of urban air pollution is caused by non-exhaust emissions (NEE). Brake wear is one of the sources of NEE. When brakes are applied, the friction between the brake pad and disc generates tiny particles that are released into the atmosphere. Euro 7 standards are expected to drive further investigation and potential regulations on NEE, pushing manufacturers to innovate in brake technology.
PASSENGER CARS AND VANS
For lighter vehicles such as passenger cars and vans, there has been a steady shift towards electric and hybrid technologies, which inherently reduce brake wear. Regenerative braking systems use the vehicle's electric motor to slow it down, reducing the reliance on traditional friction brakes. This results in lower emissions, which is in line with Euro 7 standards. As a result, brake wear is reduced, leading to a decrease in NEE from these vehicles.
TRUCKS AND BUSES
Trucks and buses pose a greater challenge. Due to their large size and weight, these vehicles require strong braking systems that produce a significant amount of brake wear particles compared to passenger cars. Manufacturers may need to investigate advanced materials for brake pads and discs that emit fewer particles when worn down.
REGENERATIVE BRAKING
Regenerative Braking in Heavier Vehicles: Electric trucks and buses are still in their early stages compared to passenger EVs. However, the growth in this segment could introduce regenerative braking to larger vehicles. This would not only extend the life of the brakes but also further reduce NEE.
Euro 7 could hasten the transition to electric commercial vehicles, indirectly benefiting the environment through reduced brake wear.
RESEARCH AND MONITORING
As the industry progresses with these advancements, it is crucial to closely monitor brake wear emissions. Real-world and laboratory testing will provide accurate data on the effectiveness of new brake technologies in reducing NEE. This could lead to further revisions in regulations, guiding manufacturers in producing the most environmentally friendly brake systems. In conclusion, it is important to prioritize the reduction of brake wear emissions in the pursuit of a more sustainable future.
CONCLUSION
The Euro 7 emission standards demonstrate the EU's dedication to significantly reducing vehicle pollution. Although exhaust emissions have been a major focus, non-exhaust emissions, even those from brake wear, are now receiving attention. The automotive industry is poised for another significant transformation, with advancements in brake materials and the increasing use of regenerative braking systems. These changes will contribute to a cleaner and more sustainable future for urban mobility.
