TRADE-OFFS BETWEEN FUEL EFFICIENCY AND EMISSIONS

The trade-offs between fuel economy and emissions and improvements in fuel economy that allow elimination of add-on devices are addressed. The cold-start emission problem for conventional engines is also discussed. This paper provides some background and estimates on fuel economy for various emission constraints and some estimates of the percentage of fuel economy improvement necessary to eliminate add-on devices. The conclusions are that add-on devices cannot be eliminated by the projected fuel economy gains and that improved carburetor designs and manifold systems have their largest impact on the cold-start problem.
