The Quiet Heavy Vehicle (QHV) project was undertaken to determine the technical feasibility and cost of reducing the noise levels of heavy diesel-engined goods vehicles. This study was concerned with the results of data gathered to: evaluate the durability of the noise reduction measures achieved (viz. 10dB(A) below emission levels for an untreated vehicle); assess running costs; and identify any maintenance problems. It was concluded that during a 2 year period the QHV gave an average fuel consumption similar to that of unmodified vehicles; required a 1.5% increase in maintenance (equivalent to 0.2% increase in total operating cost); and, by steam cleaning the silencer, retained the required noise reduction level over the period.
