Following the report of the Armitage Inquiry and the resulting UK Government White Paper 'Lorries, People and the Environment', the government initiated a cooperative programme of research and development with the UK commercial vehicle industry to produce quiter lorries for the 1990s. The aim of this programme, known as the QHV90 Project and managed by the Transport, and Road Research Laboratory of the Department of Transport, and the Department of Trade and Industry, is to support commercial vehicle and engine manufacturers in the production of the quieter prototypes required to meet the lower noise levels embodied in the forthcoming EEC legislation. This legislation requires a reduction in sound pressure level for the heavest vehicles from 89 dB(A) at present to 84 dB(A) in 1989/90. The cost of the work is being borne half by government and half by industry. The principal manufacturers involved include ERF, Foden, Iveco-Ford and Leyland for the quieter vehicle prototypes and Perkins, Cummins and Ford for the quieter engines. In addition to the work being carried out by the manufacturers, research on specific aspects of vehicle noise, for example on exhaust and air inlet and engine design, is being done by the Motor Industry Research Association, Loughborough University of Technology, the British Hydromechanics Research Association, the Institute of Sound and Vibration Research and Ricardo Consulting Engineers. This paper will describe the QHV90 Project and present some of the results obtained.
