To meet the increasingly exacting emission control standards that are emerging, alternative fuel vehicles will be needed. It appears that these will require optimised and dedicated systems utilising innovative control strategies to achieve the necessary standards. In this paper, the major emission control issues for engines fuelled with alcohol, natural gas, propane, or diesel fuels are identified. Control strategies employing dedicated emission control catalysts are discussed and performance results from laboratory, engine and vehicle tests are highlighted. Comparisons are made with gasoline fuelled engines, where significant experience has been accumulated over the past decade with the use of closed loop fuel control plus a catalytic converter to suppress the three main polluting emissions. The use of catalytic converters containing flow through catalysts is emphasised.
