EFFECT OF ENERGY AND EMISSION CONSTRAINTS ON COMPRESSION RATIO

This paper describes the results of a study to evaluate the relationship of compression ratio on fuel energy conservation with the constraint of the 1977 Federal emission standards (1.5 HC, 15.0 CO and 2.0 NOX). The influence of the energy losses in the refinery process to produce higher octane fuels was considered as well as the effect of compression ratio on engine efficiency. Two different emission control systems were evaluated: a catalytic converter-EGR system and a manifold reactor-EGR system. /GMRL/
