A NOx trap catalyst was evaluated in a light-duty diesel engine bench under steady-state
speed/load conditions with alternating lean and rich exhaust streams. The NOx conversion …

Storage and regeneration events have been studied using fast-response emission
analysers (∼ 10 ms) for a lean NO x trap (LNT) fitted to a light-duty diesel engine. Tests …

Direct-injection diesel engines have become prime candidates for future transportation
needs owing to their high thermal efficiency. However, the increase in nitrogen oxides (NO …

A NO x trap catalyst was studied in a laboratory reactor under simulated diesel passenger
car conditions. The effects of lean/rich duration and the nature of reductant are investigated …

To minimize nitrogen oxide (NOx) as well as carbon monoxide (CO) and hydrocarbon (HC)
emissions to fulfil the new European real driving emissions (RDE) legislation, the LNT …

This paper presents a mathematical model for the simulation of NOx traps during the storage
and the regeneration phases. The objective is to validate the model under realistic exhaust …

ABSTRACT Lean NOx Traps (LNTs) are one type of lean NOx reduction technology typically
used in smaller diesel passenger cars where urea-based Selective Catalytic Reduction …

Lean NOx Trap (LNT) catalysts are capable of reducing NOx in lean exhaust from diesel
engines. NOx is stored on the catalyst during lean operation; then, under rich exhaust …

A novel method to measure the oxygen storage capacity (OSC) and the NOx storage
capacity of lean NOx traps (LNT) has been developed. The method relies on closed loop …

A high-efficiency NOx aftertreatment system has been proposed for use in Diesel engines.
This system includes a Lean NOx Trap (LNT) in series with a Selective Catalyst Reduction …
