Air inlet control method for spark ignition supercharged internal combustion engine of motor vehicle, involves increasing quantity of air admitted in cylinder if determined air density is lower than threshold density

摘要

The method involves determining the density of air in an inlet of a compression stage (34) of a turbocharger (36) by calculating the pressure or temperature of air in the upstream of the compression stage. The quantity of air admitted in a cylinder (10) is increased, without an action on the turbocharger, if the density of air is lower than a threshold density.
