This Diesel Engine Catalyst market report provides a comprehensive analysis of the market’s characteristics, size, and growth, including segmentation, regional and country-level breakdowns, competitive landscape, market shares, trends, and strategies. It also tracks historical and forecasted market growth across various geographies.

The diesel engine catalyst market size has grown strongly in recent years. It will grow from $32.88 billion in 2024 to $35.63 billion in 2025 at a compound annual growth rate (CAGR) of 8.3%. The growth in the historic period can be attributed to rapid urbanization, industrial growth, expansion of the automotive industry, growth in global trade and transportation, and increasing consumer preference for environmentally friendly vehicles.

The diesel engine catalyst market size is expected to see strong growth in the next few years. It will grow to $48.44 billion in 2029 at a compound annual growth rate (CAGR) of 8%. The growth in the forecast period can be attributed to stricter emissions regulations worldwide, rising Awareness of air pollution, significant investments in research and development, high demand for commercial vehicles, and the growing use of renewable diesel fuels. Major trends in the forecast period include technological advancements, improvements in catalyst technologies, development of selective catalytic reduction (SCR), implementation of after-treatment systems, and improvements in fuel efficiency standards.

The expansion of the commercial vehicle sector is anticipated to drive growth in the diesel engine catalyst market moving forward. Commercial vehicles encompass motor vehicles used for transporting goods or paying passengers, categorized by their gross vehicle weight rating (GVWR) or passenger capacity. Growth in this sector is spurred by economic expansion, heightened demand for freight transport fueled by e-commerce and infrastructure development, and the imperative to replace older trucks with more advanced, fuel-efficient models. Diesel engine catalysts in commercial vehicles mitigate emissions of pollutants such as NOx, CO, and particulate matter, ensuring compliance with stringent environmental regulations while enhancing fuel efficiency. For instance, in April 2024, new EU sales of commercial vans surged by 12.6% compared to the same period in 2023, reaching nearly 400,000 units. Similarly, commercial bus registrations rose by 23.3%, totaling 9,624 units. Consequently, the growth in the commercial vehicle sector is underpinning the expansion of the diesel engine catalyst market.

Key players in the diesel engine catalyst market are concentrating on advancing products such as NOx adsorbers to better cater to customer needs. NOx adsorbers, also known as lean NOx traps (LNTs), are emission control devices deployed in internal combustion engines to curtail nitrogen oxide (NOx) emissions. For example, in June 2024, Veneporte, S.A., a Portugal-based auto parts manufacturer, launched new lean NOx trap products renowned for their effectiveness in significantly reducing harmful emissions from diesel engines. This release underscores Veneporte's commitment to innovation and sustainability, providing customers with state-of-the-art technologies for a cleaner future and delivering fresh emission control solutions to the market.

In February 2024, Hensel Recycling GmbH, a Germany-based leader in precious metals recycling, acquired Red Fox Resources to optimize logistics, thereby accelerating service delivery, lowering shipping costs, and reducing carbon emissions. Red Fox Resources, a US-based provider of diesel engine catalysts, was the target of this undisclosed acquisition, aimed at strengthening Hensel Recycling's operational efficiency and environmental footprint.

A diesel engine catalyst (DEC) is a specialized catalytic converter designed for diesel engines to reduce emissions of carbon monoxide, hydrocarbons, and the organic fraction of diesel particulate matter. These catalysts effectively convert these harmful substances into less toxic carbon dioxide and water through catalytic oxidation reactions. DECs are well-established and widely implemented in commercial practice for controlling diesel engine emissions, often integrated with other after-treatment devices such as diesel particulate filters and selective catalytic reduction systems.

The primary types of diesel engine catalysts include honeycomb catalysts, pellet catalysts, and monolith catalysts. A honeycomb catalyst features a ceramic structure with a network of parallel channels that maximize surface area for catalytic reactions. Materials such as platinum, palladium, and rhodium are commonly utilized in technologies such as diesel oxidation catalysts (DOC), diesel particulate filters (DPF), selective catalytic reduction (SCR), among others. These catalysts are applied across various vehicle types including passenger cars, light commercial vehicles, and heavy commercial vehicles, serving both on-road and off-road applications.
