Abstract
The present invention relates to a method of controlling the intake of an internal-combustion engine comprising at least two groups (12, 14) of at least one cylinder (C1-C4) wherein a feed is admitted for operation of said engine, and an exhaust line (40, 94, 100) comprising at least one exhaust gas depollution means (42, 96, 102).According to the invention, the method consists, while the engine runs at low speeds and/or at low torques, in evaluating the total feed to be admitted into the cylinders to operate the engine, in admitting a greater proportion of the total feed into one (12) of the groups of cylinders (C1, C4) than in the other (14) group of cylinders (C2, C3) so as to achieve an exhaust gas temperature increase allowing to speed up the rise in temperature of depollution means (42, 96, 102).
