Aftertreatment Technologies

Selective Catalytic Reductions (SCR)

SCR reduces nitrogen oxide (NOx) emissions by injecting a urea-based solution into the exhaust stream, where it reacts with NOx over a catalyst to form harmless nitrogen and water vapor.

Diesel Particulate Filter (DPF)

Cummins' DPF technology significantly reduces particulate emissions, enhancing air quality. It is a key component in meeting particulate emission standards.

Advanced Sensors and Controls

Smart control systems enhance the overall effectiveness and reliability of aftertreatment systems, ensuring optimal performance under diverse operational scenarios.

Diesel Oxidation Catalyst

Cummins' diesel oxidation catalyst (DOC) is designed to reduce carbon monoxide (CO) and unburnt hydrocarbons in the exhaust stream. It plays a crucial role in achieving cleaner emissions by promoting the oxidation of these harmful compounds.

SCR Catalysts

SCR catalysts utilize advanced porous wall structures and efficient catalyst materials to facilitate the selective catalytic reduction process. This results in the conversion of nitrogen oxides (NOx) into nitrogen and water vapor, aligning with emission reduction goals.

Combination Systems

Cummins' combination systems integrate multiple aftertreatment technologies to provide comprehensive emission control. By combining SCR, DPF, and other components, these systems deliver optimized performance across various operational conditions, ensuring compliance with emissions standards.

Natural Gas and H2ICE Boxes

Our Three-Way catalyst systems are used for natural gas engine applications and oxidize exhaust gas pollutants (HC and CO) and reduce nitrogen oxides into harmless components. Our Hydrogen combustion engine (H2ICE) systems use technologies similar to diesel systems such as SCR to reduce oxides of nitrogen, and particulate filters in order to meet the worlds most stringent emission standards.

Diesel Exhaust Fluid (DEF) Dosing

Precise injection of Diesel Exhaust Fluid (DEF) into the exhaust stream of engines equipped with SCR systems helps reduce nitrogen oxide emissions.

Thermal Management Technologies

Electric heaters and hydrocarbon dosers are used to optimize the performance of aftertreatment systems by maintaining the temperature of exhaust gases within the optimal range for efficient emission reduction reactions.
