Název v původním jazyce

Measurement of particulate matter emissions from diesel locomotives and rail vehicles during real-world line-haul operation

Popis výsledku v původním jazyce

Exhaust emissions were measured on 1100 kW and 1460 kW diesel-electric locomotives and a 588 kW diesel-hydraulic motor car during regular scheduled passenger service. It is not feasible to measure exhaust flow directly. It can be estimated from engine data or by other means & verified. Instrument choice is restricted by relatively severe constraints. Combination of on-road and stack (stationary) testing instrumentation & approaches. This study: Calculated exhaust flow & verification of calculations MiniPEMS: NO, NO2, CO, CO2, estimated PM (similar also used by Graver, North Carolina State Univ. in U.S.) FTIR: Additional gaseous pollutants N2O,CH4,NH3... NanoMet: Non-volatile particle number emissions Key findings: Even emissions from engines near the end of their useful life were, per passenger, comparable to newer diesel automobiles. It is expected that emissions will decrease with retrofit/repower/replacement using low-emissions diesel technology, proven on heavy-duty on-road vehicles
