    Passenger vehicle exhaust emission control

    • Internal combustion engines will still be in demand during the transition to EV lineups. Traditional emissions standards and regulations, such as United States Tier 4 and Euro Level 7 regulations, will continue to impact ICE emission control system design. With more than 45 years of experience supporting the emissions industry, 3M is here with world-leading expertise and testing methods to help find a solution for your design, helping save you valuable time and effort as automotive industry resources shift to electrification.

      3M is a leading supplier of mat mount and high-performance thermal solutions for advanced gasoline, diesel and hydrogen emission control systems for reduced CO2, NOx and PM emissions. They can be used around ceramic monoliths and filters in the following systems:

      • Three-way catalyst (TWC)
      • Selective catalytic reduction (SCR)
      • NOx absorbers
      • Ammonia storage catalysts (ASC)
      • Gasoline particulate filters (GPF)
      • Diesel particulate filters (DPF)

      3M global teams are here to collaborate with you on your light-duty and passenger vehicles applications every step of the way. We offer world-class application engineering support, labs and manufacturing capabilities in every geography.

    • See our state-of-the-art testing facilities in action.

  • Emissions standards and regulations

    If vehicles containing combustion engines are still on the road, meeting emission regulations globally will still be important. OEMs and canners are thinking about how to continue to meet regulations even with less resources dedicated to emissions systems.

    Changes to the emission systems could still be implemented to meet low exhaust emissions, including:

    • Maintaining system temperature with improved insulation
    • Converting to more fragile and porous catalysts
    • Designing updated catalyst geometrics
    • Preheating catalyst before start-up
    • Adding or increasing the size of catalysts
    • Managing increased exhaust temperature conditions and flow rates
    • Designing emission control systems and materials for more efficient, smaller engines

    3M can help with these design challenges and help find the right solution for your application. Message a 3M expert.

Tackling your toughest ICE propulsion challenges together

  • Like you, we have spent decades helping improve and maximize both the manufacturing and performance of ICE vehicles. That means we understand the challenges you face. Internal combustion engines are becoming smaller, but the components driving the powertrain must maintain material strength and increase torque to achieve higher efficiency. 3M can help.

    From one end of the powertrain to the other, 3M helps advance ICE vehicles through a network of application development and testing facilities worldwide.

  • Stabilize bolted joints in classical and advanced ICE powertrains

    Address shear protection and torque protection in ICE and hybrid engines. In hybrid engines, shear forces get extremely high due to the high torque output of electric motors and aluminium housing components have low friction. Increasing clamp force/bolt size can also deform surfaces.

    3M™ Friction Shims, which have been used in the timing elements of ICE engines for decades, enhance coefficent of friction by 5X, stabilizing joints to mitigate micromovements in hybrid engine applications.

  • 3M abrasive products

    Reduce engine size

    Smaller engines require stronger materials that are stable at high temperatures and create more precise and smoother finishes on parts.

  • Ensure top performance

    Sintered silicon nitride (Si₃N₄) is an extremely hard and corrosion-resistant ceramic material that is almost 60% lighter than steel. It offers an excellent combination of properties such as thermal and impact shock resistance, electrical insulation and wear resistance. This material is excellent for ceramic rings in oxygen (lambda) sensors which help ensure top engine performance and alert to high emissions.

  • powertrain, chassis and wheels

    Enhance your next EV battery and ePowertrain design. 3M can help you tackle tough challenges related to thermal runaway propagation, battery assembly and disassembly, eMotor assembly and more, and optimize your throughput. We combine established, world-class expertise in lithium-ion battery technologies with a century of experience in the automotive industry.

  • Electric vehicle charging

    Internal combustion engines will still be needed for commercial vehicles and fleets as near zero-emission solutions are still vetted. Spend less time and resources researching emission system material solutions and go with the trusted supplier with regulatory knowledge and over four decades in the market. 3M offers mat mount and high-performance thermal solutions for commercial and specialty vehicle applications. Choose 3M and you'll have global support through your design, testing and validation process.
