Summary:

This paper describes the continued development of the Navistar 7.3 litre V8 CNG engine. The project background, objectives and preliminary results have already been described (1).Development results show that U.S. 1994 emissions standards can be comfortably met without the use of electronic air fuel ratio control or an oxidation catalyst.Transient cycle emissions of 1.7 g/bhph NOx + NMHC have been obtained from de-rated engines to be used in field demonstration vehicles.Electronic control will allow 2.5 g/bhph NOx + NMHC to be achieved without de-rating. Further emissions reduction without aftertreatment will depend on aftercooling, which also offers the potential for an increased rating
