Catalysts for Diesel Engines

Emissions from diesel engines are of increasing concern to government regulators around the world. Cars, trucks and off-road equipment that run on diesel fuel are the source of harmful hydrocarbons (HC), nitrogen oxides (NOx) and particulate matter (PM) that pollute the air and are linked to respiratory diseases.

We are a leading supplier of cost-efficient, effective diesel-emission-control technologies.

These technologies are in use today on most of the diesel vehicles produced around the world.

BASF maintains significant diesel research and development facilities around the world. These facilities are being used to develop the technologies needed to meet the extremely low emission levels called for in new emissions regulations.

Catalyst technologies for diesel engines include:

These technologies can be combined to meet emission regulations. To learn more, view our article below.

Diesel Oxidation Catalysts (DOC)

BASF's Diesel Oxidation Catalyst (DOC) technology controls emissions of hydrocarbons (HC), carbon monoxide (CO) and particulate matter (PM) from diesel vehicles.

Lean NOx Trap (LNT)

On one substrate a Diesel Oxidation Catalyst (DOC) and a Lean NOx Trap (LNT) are combined. This component has the high HC and CO removal efficiency of a fully formulated DOC, with the ability of a LNT to trap and reduce NOx.

Selective Catalytic Reduction (SCR)

BASF Catalysts technologies enable customers to meet tightening NOx emission standards around the world.

Selective Catalytic Reduction on Filter (SCRoF)

SCR on Filter controls NOx (nitrogen oxides) and PM (particulate matter or soot) emissions from diesel engines, on a single substrate.

Ammonia Oxidation Catalysts (AMOx)

BASF’s patented AMOX ammonia oxidation catalysts are designed to prevent ammonia breakthrough or slip in SCR (Selective Catalytic Reduction) systems.

Catalyzed Soot Filters (CSF)

BASF's Catalyzed Soot Filters (CSF) (also called diesel particulate filters or DPF) are designed to reduce emissions of particulate matter (PM) from diesel engines.

Multi-functional Catalyzed Soot Filters

The CS4F (multi-functional catalyzed soot filter) with a LNT is a solution to meet strict Euro6 emission regulations.

Retrofit

BASF is a leading supplier of cost-efficient diesel-emission-control technologies for the retrofit market, including Diesel Oxidation Catalysts and Diesel Particulate Filters, which are in use today on thousands of trucks and buses around the world.
