1. A system for aiding the regeneration of pollution-control means that are integrated in an exhaust line of an engine of a motor vehicle, in which the engine has a plurality of cylinders,said system comprising means for the common supply of the cylinders of the engine, said supply means being in a form suitable for injecting fuel, during regeneration, into each cylinder in the form of at least one principal injection and at least one post-injection during the expansion phase of the cylinder, wherein the supply means comprise means for cutting at least the principal injection of at least one of the cylinders and maintaining at least the principal injection of at least one other of the cylinders, during regeneration, in order to increase the oxygen content of the exhaust gases and to optimise the regeneration of the pollution-control means. 2. A system according to claim 1, wherein the supply means comprise means for cutting the principal injection into a different cylinder at each engine cycle during regeneration.3. A system according to claim 2, wherein the supply means comprise means for cutting the principal injection of the consecutive cylinders of the engine one after another during regeneration.4. A system according to claim 1, wherein the pollution-control means comprise a particulate filter.5. A system according to claim 4, wherein the particulate filter is a catalysed particulate filter.6. A system according to claim 1, wherein the pollution-control means comprise a NOx trap.7. A system according to claim 2, wherein the pollution-control means comprise a NOx trap.8. A system according to claim 3, wherein the pollution-control means comprise a NOx trap.9. A system according to claim 1, wherein the pollution-control means comprise a catalysed or non-catalysed particulate filter associated with a NOx trap.10. A system according to claim 2, wherein the pollution-control means comprise a catalysed or non-catalysed particulate filter associated with a NOx trap.11. A system according to claim 3, wherein the pollution-control means comprise a catalysed or non-catalysed particulate filter associated with a NOx trap.12. A system according to claim 1, wherein the supply means comprise means for providing a pre-injection of fuel into the engine cylinders before the principal injection.13. A system according to claim 1, wherein the supply means comprise means for cutting at least the principal injection and maintaining the post-injection of at least one of the cylinders during regeneration.
