Worldwide revenue from the automotive exhaust aftertreatment system market is estimated at US$ 24.1 billion in 2024 and has been calculated to increase at a CAGR of 3.6% to reach US$ 36.02 billion by the end of 2034.

An aftertreatment system is a technique designed to reduce harmful exhaust emissions from internal combustion engines. In simpler terms, it is a mechanism that cleanses exhaust gases to ensure compliance with pollution standards.

Rising greenhouse gas emissions from cars and the increasingly stringent enforcement of related regulations are driving market growth. The market may encounter constraints due to the absence of biodiesel exhaust after-treatment systems and the complexities associated with urea injection setups. Furthermore, the growing production of automobiles, particularly commercial vehicles, is projected to create lucrative market opportunities for manufacturers of automotive exhaust aftertreatment systems during the forecast period.

Demand for automotive particulate filters is primarily attributed to concerns surrounding escalating carbon emissions regulations, prompting the enactment of various regional and global laws aimed at reducing emissions. Businesses are adopting strategies such as selective catalyst reduction to enhance the efficiency of particle filters. Sales of vehicles powered by renewable sources are boosting demand for eco-friendly transportation solutions. This shift redirects funding towards the development of alternatives such as electric vehicles.

The automotive ventilation system market is intricately linked to the volume of car manufacturing. As a result, the rising production of trucks and passenger vehicles in developing countries is contributing to steady global automotive exhaust aftertreatment system market growth.

How are Automakers Responding to Stringent Emission Regulations?

“Integration of Aftertreatment Devices in Response to Need for Reducing Emissions”

Emission standards worldwide are becoming increasingly stringent with every passing year, leading to a rise in demand for reducing both the particulate matter and quantities of exhaust gas emissions. Integration of after-treatment devices allows automotive OEMs and exhaust system manufacturers to keep vehicle emissions within mandated regulatory limits.

Among the most commonly utilized combinations of after-treatment devices are SCR and DPF. This pairing eliminates over 70% of both gaseous and particulate matter emissions. SCR works by converting NOx into harmless nitrogen and water with the aid of a reductant, while DPF functions to filter out particulate matter.

  • For instance, BASF's Catalysts division offers a blend of a Diesel Oxidation Catalyst (DOC) and a Lean NOx Trap (LNT).

This combination of DOC and LNT offers the high efficiency of HC and CO removal provided by a fully developed DOC, coupled with the capability of an LNT to capture and diminish NOx. Such integration allows exhaust systems to effectively manage emissions within the confines of Euro 6 emission standards for diesel engines. Consequently, these synergistic combinations are fueling the demand for after-treatment devices.

“Industry-Wide Efforts to Reduce Weight of Exhaust Systems and Their Components”

Reducing vehicle weight is increasingly necessary to adhere to stringent pollution and fuel efficiency regulations and to avoid harsh penalties from government authorities. A lighter vehicle requires less gasoline to overcome inertia and thus demands less power to operate, resulting in reduced overall fuel consumption and CO2 emissions. Experts suggest that reducing vehicle weight can enhance mileage by approximately 6% to 8% and improve fuel efficiency by up to 10%.

Automotive original equipment manufacturers are focusing on various areas to decrease vehicle weight, including the development of innovative lightweight materials, aerodynamic design, and enhancing drive train efficiency (engine/transmission).

Traditional exhaust systems utilize materials such as cast iron, stainless steel, and mild steel/carbon steel, among others, for construction. However, several automakers, exhaust system manufacturers, and other entities are striving to lighten the weight of exhaust systems and their components. These are some of the key automotive exhaust aftertreatment system market trends.

What are the Hindrances to Market Expansion?

“Growing Demand for Low-Emission Vehicles and Initiatives Promoting Electric Vehicle Usage”

BEVs, CNG, and LPG-powered automobiles are examples of clean cars. Growing demand for low-emission vehicles is projected to boost sales of CNG and LPG-fueled vehicles during the forecast period. Because CNG and LPG-fueled cars boast substantially lower running costs compared to petroleum-fueled vehicles, they are considered economical.

Sales of BEVs, recognized as the most environmentally friendly vehicle type, are on the rise, due to various government regulations and successful initiatives such as tax breaks promoting electric vehicle usage. Electric car sales are rapidly increasing due to government initiatives and growing environmental awareness.

Cars powered by CNG and LPG utilize simpler exhaust systems devoid of after-treatment components like DPF, DOC, SCR, LNT, or GPF. This reduces the revenue generated by the exhaust system industry compared to ICE-powered vehicles. Conversely, BEVs propel the vehicle using an electric motor, eliminating the need for exhaust components or other types of after-treatment equipment.

Due to the global surge in BEV popularity, especially in countries like the United States and China, exhaust system manufacturers are projected to lose a significant portion of their share. Currently, clean cars have minimal impact on the exhaust system industry, but they are projected to exert a substantial influence in the near future.
