| Summary: | The increasing concerns on fuel prices, lowest fuel consumption, higher operating
efficiency and low levels of carbon monoxide and unburned hydrocarbon during cold start
have generated noticeable interest on diesel engine as a prime mover with expected higher
soot and NOX emissions. In order to reduce the emission from diesel fuelled vehicle, some
control technologies were introduced. One of the technology is diesel particulate filter
(DPF) which consists of a porous substrate that permits exhaust to pass through but traps
particulate matter (PM) or carboneous soot. Conventional DPFs are manufactured using
expensive materials. In this study, alternative material based on alumina and zeolite was
used to form porous ceramics filter installed in diesel fuelled vehicle exhaust system and
named as novel diesel particulate filter (NDPF). The NDPF elements were arranged in
line with 1cm spacing inside an enclosed casing. The NDPF showed potential as DPF to
curb soot emissions. Pressure drop for the NDPF was in the range of 89% - 93% at every
given flow rate during pressure drop test. Effective soot reduction was in the range of 60%
- 70%. As predicted, trapped soot were accumulated mostly at the front and middle of
NDPF. Scanning electron microscope (SEM) and energy dispersive xray (EDX) analysis
confirmed the trapping ability of carbon elements in the range of 19% - 70% for each
filter. Brake specific fuel consumption (BSFC) and brake mean effective pressure (BMEP)
was slightly affected when NDPF was installed in the exhaust system and resulted to drops
in engine efficiency in the range of 2% - 26%. Nevertheless, further reinforcement steps
for the NDPF are needed to prolong its filtering capacity |
