Emission Reduction Retrofit Kits for Road Vehicles and Metro Systems

transportTestedTRL 6

Imagine giving an old car or train a high-tech filter upgrade to make it breathe cleaner. This work focuses on catching tiny pollution particles from exhaust pipes and brake pads before they hit the air. It's like adding a professional air purifier to a vehicle's braking and exhaust systems to protect people in crowded cities and tunnels.

The business problem

What needed solving

Existing vehicle fleets are aging and many lack particulate filters, while new Euro 7 regulations now penalize brake particle emissions. This creates a compliance gap for fleet operators and a health risk in urban and underground environments.

The solution

What was built

Innovative tailpipe retrofit kits for NOx and particles, active brake filtration systems, and low-wear brake discs and pads.

Business applications

Who can put this to work

Urban Logistics
enterprise
Target: Delivery fleet operator

If you are a delivery fleet operator dealing with aging vans that emit high particles in city centers — this project developed tailpipe and brake retrofit solutions that reduce NOx and particle emissions. This helps your fleet meet stricter urban air quality standards without replacing every vehicle.

Public Transit
enterprise
Target: Metro system operator

If you are a metro system operator dealing with hazardous metal particles in underground stations — this project developed active filtration systems and machined pads. This reduces the health risks for passengers and workers in confined tunnel environments.

Automotive Aftermarket
SME
Target: Brake component manufacturer

If you are a brake component manufacturer dealing with the new Euro 7 limits on brake particles — this project developed innovative brake discs and pads. These can be sold as replacement parts for any vehicle to reduce wear and emissions.

Frequently asked

Quick answers

How does this affect the cost of retrofitting?

The project aims to minimize costs by using innovative washcoats, compact packaging, and alternative production techniques for brake components. A detailed cost-benefit analysis is conducted to highlight benefits against costs.

Can these solutions be scaled for industrial use?

Yes, the project focuses on a central development methodology that allows fast and accurate optimization for different applications, from road vehicles to metros.

What is the IP or licensing status of the retrofit kits?

Based on available project data, the project focuses on development and demonstration; specific licensing terms are not detailed in the summary.

Which regulations drive the need for this technology?

The Euro 7 regulation is a primary driver, as it introduces limits for particle emissions from brakes for the first time.

When will these systems be available for deployment?

The project period runs from 2022-12-01 to 2025-11-30, suggesting the demonstration phase concludes in late 2025.

Consortium

Who built it

The consortium is heavily industry-driven, with 13 industrial partners representing 72% of the group. This high industry ratio, combined with 4 SMEs and partners across 10 countries, indicates a strong focus on commercial viability and market integration rather than purely academic research.
