Which outcome occurs when insufficient turbulence impairs fuel injector performance?

💡 Explanation

Incomplete soot particle formation can occur because insufficient turbulence prevents complete air-fuel mixing via the Kelvin-Helmholtz instability; therefore, the engine emits black smoke pollutants rather than achieving full stoichiometric oxidized products; catalytic converters manage normally combusted exhaust.
