Emission testing of a transport refrigeration unit.

Number: pap. n. 1688

Author(s) : LAWTON R., MYNOTT T., MARSHALL N., et al.

Summary

Standards for exhaust emissions for road vehicles have enforced a significant reduction in particulates and NOx for transport vehicles complying to those standards. However, several larger UK conurbations have noticed that pollutants are not being reduced as much as had been hoped and that those measured at the roadside are from such sources as older vehicles, non-regulated engines, brakes and even tyres. One source is diesel engines powering nose-mounted refrigeration units, where it is common for the engine to be devoid of any emission controls. Data is presented on testing carried out on a nose-mounted refrigeration unit at different temperature setpoints and conditions, with varying internal load: empty and with simulated cargo. The data shows that these engines do contribute to both NOx and particulates and that the current non-road mobile machinery regulation (“NRMM”) will not significantly reduce those emissions.
