Abstract

While it may appear to the consumer that there has been a period of relative stability in automotive technological development in recent years, there are a number of factors exerting pressure on motor manufacturers to develop a new generation of vehicles producing lower emissions of species that have an adverse effect on health and the environment. The development of such vehicles for use in the UK and Europe is being driven by changing legislation that will require significant reductions in key emissions; in most cases the allowed emissions of such species will be approximately halved [see Section 2]. Motor manufacturers intend to meet these demands via a number of means including the optimisation of conventional combustion engines [improved injection, camless engine technology, etc.], improved exhaust aftertreatment technology [improved catalysts, particulate filters, etc.], the use of alternative fuels [biodiesel, LPG, etc.] and the introduction of electric motor assisted hybrid vehicles.
This report summarises the key emissions species, legislation affecting the allowed emissions of these species, alternative fuels and their effects on emissions and finally the analytical and sampling methods used to test and validate new spark ignition and compression ignition engines, and the associated measurement requirements which will need addressing.
