Harrington, J A

The influence of carburetor characteristics on power, emissions, lean misfire limit and EGR tolerance has been investigated using a single-cylinder engine. The results, which are based on the use of a conventional carburetor and a modified version of the same carburetor, indicate that the lean limit and EGR tolerance are extended when time variations in fuel flow (spiking of A/F) are reduced and the mixture is made more homogeneous. The amount of extenson varies with engine load, being largest at the lighter loads studied. Power, CO and NO/sub x/ emissions of the engine are insensitive to the carburetion effects at common values of engine air flow rate and A/F. The HC emissions are affected at all but the richest A/F values investigated.
