NISSAN'S EMISSION CONTROL SYSTEMS TO MEET JAPANESE AUTOMOTIVE EMISSIONS STANDARDS
The Nissan Motor Company introduced the Nissan Anti-Pollution System (NAPS) in 1975 in response to a tightening of the Japanese emission control standards. The more stringent standards of 1978, requiring an NOx reduction of at least 80%, made a further improvement of naps necessary. To effect this improvement Nissan carried out a series of studies. The stabilisation of combustion and the effective induction of heavy exhaust gas re-circulation (egr) were studied with the aim of reducing NOx with a heavy egr. A study of a three-way catalyst system was also made with a view to reducing nox after emission from the cylinder. As a result of these studies, Nissan's models were equipped with the three most appropriate naps systems. These systems are described. (Author/TRRL)
