A Study of Reducing Particulate Matter from A Spark Ignition Engine by Wet Scrubber
Keywords:
Spark Ignition Engine, Particulate matter, Wet ScrubberAbstract
The situation in Thailand regarding to Particulate Matter (PM) level increase is known as a major cause that affects human health and environment. One of PM issues problems arise from emissions from internal combustion engine vehicles. The changing of spark ignition engine’s emission standard from EURO 4 to EURO 5 and EURO 6 that results in PM reductions will be implemented soon. Seeking PM reduction by implementing existing technologies is of interest. This reason make researcher interest about design and building of the prototype wet scrubber for deserve with vehicles and testing for reducing about emission. In the current study, a Spark-Ignition engine equipped with a wet scrubber in the exhaust system is tested on an Engine Dynamometer. Tests are done and compared between running the exhaust with and without water wet scrubber. The result shows that with wet scrubber equipment, PM can be reduced significantly. This result shows that the potential of using water absorbing PM emit from spark Ignition engine is possible. From the experimental data, the wet scrubber with water can reduce PM up to 60%. However, in term of another emission species, no significant reduction is observed.
