| Mobile Engine Emissions Laboratory installed at the Lake Lynn Diesel Laboratory |
The Lake Lynn Diesel Laboratory is an in-mine setting which allows for controlled laboratory quality studies in an actual mine environment. The core of the lab is the NIOSH Mobile Engine Emissions Laboratory (MEEL), which includes two dynamometer/engine systems. The smaller dynamometer is coupled to a naturally aspirated, mechanically controlled Isuzu C240 diesel engine. The larger dynamometer is coupled to a modern, electronically controlled, turbocharged Mercedes Benz OM904 engine. Each of the dynamometer/engine systems and all accompanying equipment is mounted on a base plate and custom built trailer that provides needed mobility. The MEEL is currently integrated into the D drift of Lake Lynn Laboratory, which serves as a full-flow constant volume sampling dilution tunnel. State-of-the-art equipment and instrumentation are used for the characterization of aerosols and gases emitted by the dynamometer/engine systems.
The NIOSH MEEL offers a unique environment for field-evaluation of diesel emissions control technologies and their effects on the quality of mine air and workers' exposure to diesel particulate matter and gases. This facility is currently used to conduct research on the physical and chemical characterization of ultrafine and nanometer aerosols emitted by diesel engines in actual occupational settings and for establishing the role of nano-particles in COPD and other occupational diseases.
