Diesel Particulate Filter Optimization

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">Recrystallized Silicon carbide (R-SiC) honeycombs have been widely used over the last couple of years as filtration media for diesel particulates filtration in passenger cars applications. Although such filters are very reliable thanks to SiC good properties and smart designs, existing devices can still be improved.

Comparison of Different Diesel Particulate Filters

Topics in Catalysis, 2009
The present investigation concerns the development of a catalytic wall-flow trap for the simultaneous removal of particulate, CO and marginally for NO x . Three different geometries (200/17, 300/12, and 300/12-HAC) of commercial SiC filters were catalyzed with a nanostructured perovskite catalyst (La–K–Cu–FeO3 + 2%Au ...

Particulate Deposition Modeling in Diesel Filter

ASME 2004 Internal Combustion Engine Division Fall Technical Conference, 2004
The objective of this work is to evaluate the possibility of extracting information about the filter loading status from the running history of the engine and to assess the interaction between spatial deposition of soot inside the porous wall and the engine operating conditions.

Diesel Particulate Filter

2019
The development of automotive emission control technology over the last five decades is one of the greatest environmental success stories of this century. Innovation of Catalytic Converter in 1970 changed the emission scenario worldwide. Later on, Diesel Particulate Filters (DPFs) were innovated in 1985 and were commercialized in the year 2000 to ...

Diagnostics for Diesel Particulate Filters

SAE Technical Paper Series, 2004
<div class="htmlview paragraph">This paper presents some of the challenges involved in diagnosing leaks in diesel particulate filters (DPFs). It concentrates on diagnosis with a pressure sensor. It is argued that not all failure modes can be detected by such a sensor, and that this method of diagnosis has far-reaching implications on the monitor ...

Electrochemical Diesel Particulate Filter

SAE Technical Paper Series, 1998
<div class="htmlview paragraph">A new concept for a particulate trap for diesel engines has been developed. The trap is a combination of a ceramic wall-flow filter and an electrochemical reactor. When trapped in the filter, the soot particles are continuously converted to carbon dioxide by an electrochemical reaction.

Measuring Particulate Load in a Diesel Particulate Filter

SAE Technical Paper Series, 2006
<div class="htmlview paragraph">A gravimetric particulate measurement system, which extracts samples isokinetically from raw exhaust, is presented to quantify the particulate mass stored in diesel particulate filters. The purpose of this measurement system is to facilitate the study of wall-flow filter behavior at different particulate load ...

Hydrodynamics of Diesel Particulate Filters

SAE Technical Paper Series, 2002
<div class="htmlview paragraph">Renewed interest in utilizing wall-flow Diesel Particulate Filters (DPF) in emission control systems necessitates gaining deeper engineering insight into their performance. Even though most key performance characteristics of a DPF such as pressure drop, regeneration, and light-off are highly driven by the flow ...
