Automotive Exhaust Aftertreatment Systems Market Analysis

The Automotive Exhaust Aftertreatment Systems Market is expected to register a CAGR of greater than 18.5% during the forecast period.

The COVID-19 pandemic had a severe impact on the market. With the record low sales of passenger and commercial vehicles worldwide, the demand for exhaust after-treatment systems was almost significantly affected. The lockdown and social distancing norms worldwide caused the aftermarket business of the after-treatment systems to plummet. However, with the restrictions gradually being relaxed, the growing need for lesser emissions from vehicles of all sizes, and strict emission norms levied by governments of different nations, the future market for this industry looks hopeful.

Technical difficulties, such as high pressure to force the exhaust through the filtering system, unavailability of these systems for biodiesel, passive regeneration system requiring highway driving to clean the accumulated soot, and complicated set-up for urea injection have acted as barricades for the market growth. However, the recovering global automotive industry and increasing production sites in developing nations, such as Mexico and India, are opening up new opportunities for market growth by 2027.

Automotive Exhaust Aftertreatment Systems Industry Overview

Some of the major players dominating the market are CDTi Advanced Materials Inc., Delphi Technologies PLC, Continental Reifen Deutschland GmbH, Tenneco Inc., and Donaldson Company Inc., among others. The companies are planning to tap the market by introducing or expanding their product portfolio. Increasing pressure from emission regulation authorities has forced manufacturers to come up with new technologies, which reduce the emission of polluting gases from the exhaust. This has compelled the manufacturers to increase R&D spending, to manufacture better exhaust aftertreatment technologies. For instance,

  • In March 2021, Eaton and Tenneco partnered to build an integrated thermal management system that will enable commercial vehicles to meet stringent emission regulations. This system provides heat directly to the aftertreatment systems that can reduce harmful exhaust emissions.

The increasing number of suppliers of exhaust aftertreatment systems and their joint ventures with local suppliers putting emphasis on expanding their presence resulted in improving production capacity.
