Mazda Awarded for Research into
Combustion of Catalysts in Diesel Particulate Filters
Hiroshima – Mazda Motor
Corporation has announced that it will receive the Outstanding
Technical Paper Award at the 58th annual Society of Automotive
Engineers of Japan awards ceremony in May. Mazda will be
honoured for its analysis of the combustion mechanism of
catalysts in diesel particulate filters.
Mazda has been conducting research
into combustion mechanisms to eliminate particulate matter,
mainly soot, from diesel engine exhaust emissions. The
Hiroshima-based company developed an original analytical method,
which demonstrated that the oxygen exchange characteristics of
catalysts play an important role in accelerating the combustion
of particulate matter.
This work will aid development of
highly-efficient diesel particulate filters (DPF) in the future.
Additionally, the newly-developed analytical method can be
applied not only to automobile diesel engines, but also to
general-purpose diesel engines. The award recognizes these
achievements, which provide tangible development guidelines for
a wide range of future diesel engine technologies.
Diesel engines are popular mainly
in Europe because they have better fuel economy than gasoline
engines and produce fewer CO2 emissions, which are commonly
regarded as a major cause of global warming. However, a
treatment process (combustion) is necessary to remove the
particulate matter (soot) that is produced in the exhaust. To
promote combustion of the particulate matter, the exhaust gases
must be heated sufficiently. This requires extra fuel and is one
of the causes of impaired fuel economy.
