As such, current MARPOL, US Federal, and California Air Resources Board emissions regulations dictate engine exhaust emission limits on CO, NOx, Total Hydrocarbons (THC), and Particulate Matter (PM). The Marine Engine Testing and Emissions Laboratory (METEL) at Maine Maritime Academy (MMA) was created to assist and address the emission reduction needs of the marine industry due to regulatory requirements. This report outlines the development of a Continuous Emissions Monitoring System (CEMS) to quantify all gas and particulate emission from laboratory testing and on board vessel testing at sea. A Fourier Transform Infrared (FTIR) spectrometer was selected to measure gaseous emissions while a Scanning Electrical Mobility Spectrometer (SEMS) was employed to measure exhaust particulate matter emissions. This report outlines the instrumentation and testing procedures developed to create the continuous emissions monitoring system at the METEL. Outstanding issues and suggested improvements are also outlined to aid the development of future CEMS.131
