Effects of the Degree of Fuel Atomization on Single-Cylinder Engine Performance

An investigation has been made to determine the effects of the degree of fuel atomization on exhaust emissions, fuel consumption, lean limit, MBT spark timing, and cyclic variations in peak cylinder pressure. A single-cylinder engine was used to isolate the effects of atomization on combustion from the additional effects of maldistribution that would be present in a multicylinder engine. Results from this investigation show that the degree of atomization can have considerable effect on exhaust emissions, but little effect on fuel consumption. /GMRL/
