Measurement of exhaust emissions of railroad locomotives during real-world operation using an on-board system
Original language description
Exhaust emissions were measured on a Czech Railways 749 series diesel-electric locomotive. On-track NOx, PM, CO and CO2 emissions were measured by a portable, on-board system, placed in the engine room of the locomotive, and sampling undiluted exhaust from the stack. PM emissions were measured online by a semi-condensing integrating nephelometer, calibrated by simultaneous gravimetric measurement during steady-state operation. The test was successful and demonstrated the feasibility of the approach chosen. The operation of the engine was very different than during traditional load bank tests, and consisted of interleaved periods of idle and higher load, defined by train mass and track profile (posted speed and track grade), and relatively quick progression through lower power settings. Transient emissions during load increases, and PM deposition at idle and reentrainment at higher load are important factors that should be considered in locomotive emissions tests.
