What Is Covered Under Automotive Diesel Exhaust Fluid Market?

Automotive diesel exhaust fluid (DEF) is a liquid used in diesel engines to reduce harmful emissions. It is composed of 32.5% urea (a compound made from ammonia and carbon dioxide) and 67.5% deionized water. It is stored in a separate tank in the vehicle and is automatically injected into the exhaust system essential for maintaining the performance of SCR systems and ensuring compliance with emissions standards. The main types of products in automotive diesel exhaust fluid are diesel exhaust fluid, diesel exhaust fluid (DEF) pumps, and diesel exhaust fluid (DEF) tanks. Diesel Exhaust Fluid (DEF) is a clear, non-hazardous fluid used in diesel engines equipped with Selective Catalytic Reduction (SCR) technology to reduce harmful nitrogen oxide (NOx) emissions. It can be packaged in bottles, drums, intermediate bulk containers (IBCs), and bulk delivery in various sizes, such as up to 10 liters, 11 to 25 liters, 26 to 50 liters, above 50 liters, and more than 400 liters. It uses technologies including selective catalytic reduction (SCR) and exhaust gas recirculation (EGR). This fluid can be distributed through automotive company-operated stores, auto parts stores, independent workshops, online retailers, and other outlets

What Is The Driver Of The Automotive Diesel Exhaust Fluid Market?

The growing number of diesel-powered vehicles is expected to propel the growth of the automotive diesel exhaust fluid market going forward. Diesel-powered vehicles refer to automobiles that utilize diesel engines, where fuel ignites from the high temperature created by compressing air in the engine's cylinders. The number of diesel-powered vehicles is growing due to their superior fuel efficiency, high torque output, and advancements in emissions technology, making them particularly advantageous for commercial, industrial, and heavy-duty applications. Automotive diesel exhaust fluid (DEF) helps diesel-powered vehicles reduce harmful NOx emissions, ensuring compliance with environmental regulations and maintaining engine performance. For instance, in January 2023, according to a report published by the Bureau of Infrastructure and Transport Research Economics, an Australian-based professional non-governmental organization, diesel-fueled vehicles on the register totaled around 6.0 million on 31 January 2023, an increase of 5.3% over 31 January 2022. Therefore, the growing number of diesel-powered vehicles is driving the growth of the automotive diesel exhaust fluid industry.

Global Automotive Diesel Exhaust Fluid Market Trends and Insights

Major companies operating in the automotive diesel exhaust fluid market are focusing on broadening their DEF formulation offerings, such as anti-crystal additive concentrate, to improve overall vehicle efficiency in compliance with increasingly stringent emissions regulations. Anti-crystal additive concentrate refers to a specialized additive used in diesel exhaust fluid (DEF) to prevent the formation of crystals, which can clog or damage the exhaust system. For instance, in March 2024, Liqui Moly GmbH, a Germany-based manufacturer of lubricants, introduced the new DEF anti crystal additive concentrate, an additive for AdBlue, designed to boost diesel engine efficiency while ensuring adherence to nitrogen oxide emission standards. This innovative product is designed to be added directly to the AdBlue tank, providing a convenient solution for vehicle owners to maintain the efficiency and longevity of their exhaust gas treatment systems. Additionally, the concentrate helps prevent the formation of urea crystals and deposits that could clog the AdBlue system and cause engine issues. It also lowers the freezing point of the solution to about -16°C, protecting against freezing in cold conditions.
