EMISSIONS, FUEL ECONOMY, AND DURABILITY OF LEAN BURN SYSTEMS

Several makes and models of cars were modified for lean-burn operation using the Turbulent Flow Manifold (TFM), a unique intake manifold that provides improved preparation and distribution of the fuel-air mixture. Operation of the TFM is described, and exhaust emissions and fuel economy data are presented for the various cars. Exhaust port liners and thermal reactors were shown to be effective devices for reducing emissions from the basic lean-burn system. /GMRL/
