The Road Vehicles (Construction and Use) (Amendment) Regulations 1999
These Regulations amend the definition of “the emissions publication” in Schedule 7B to the Road Vehicles (Construction and Use) Regulations 1986 so as to refer to the most recent (i.e. the fifth) edition of this publication. The publication specifies, with respect to vehicles with spark ignition engines, the maximum permitted carbon monoxide content of exhaust emissions at idling speed and the limits for the ratio of air to petrol vapour entering the combustion chamber, in relation to each of the vehicle models named in the publication.
