Marine Emissions Testing Laboratory


In-Use Marine Mobile Emissions Laboratory

Cargo ShipCE-CERT's  marine laboratory features multi-gas analyzers (Horiba PG350) to measure the concentrations of carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), nitric oxide (NOx), and sulfur oxide (SOx) gasses in raw exhaust, as well as to provide particulate matter (PM) measurements for diluted exhaust. Unlike other portable gas analyzers that rely upon electro-chemical sensors, the Horiba PG-350 utilizes the same measurement principles as a permanently installed CEMS, and is in compliance with MARPOL ANNEX VI. The methods utilized are state of the art, and follow ISO 8178 as well as 1065 measurement protocols.

 Heavy Fuel Oil (HFO) Marine 2-Stroke Engine Test Platform

Available at UCR is a one-of-a-kind marine engine test-stand system for the evaluation of marine fuel emissions, after treatment systems, and other novel ideas for the marine sector. This laboratory has been operated on commercial heavy fuel oils (HFOs) with a wide range of viscosities. The marine test engine is a 2-stroke Detroit Diesel Model 6-71N (naturally aspirated), with an in-line 6 cylinder configuration, a maximum rated speed of 2300 RPM (range 1100-2300 RPM), a maximum engine power of 187 kW, a brake mean effective pressure (BMEP) of 641 kPa, and an associated rated brake specific fuel consumption (BSFC) of 307 g/kWh (0.505 lb/hp-hr) at 1100 RPM (N70 injectors used during testing). This type of engine is typically used on small vessels or as an auxiliary engine on ocean going vessels (OGVs). OGVs usually switch to auxiliary engines when approaching port or other areas where more maneuvering is required.
