An extended Zeldovich mechanism, which models the kinetics of nitric oxide formation, is included in a multizone combustion model. The combustion model is subsequently integrated into a well-developed emptying and filling engine code to predict the transient nitric oxide emissions in the exhaust of a diesel engine. The predicted nitric oxide emissions, in terms of ppm level, have been validated satisfactorily with the experimental results obtained from a computer-controlled dynamic engine test bed on which a fully instrumented, turbocharged, direct injection (DI) diesel engine and a fast response regenerative d.c. dynamometer are mounted. The experimental results used in the comparison were reconstructed from the nitric oxide emission signals obtained by a conventional, slow response, chemiluminescence analyser.
