A low pressure injection nozzle 2 injects fuel into an air nozzle 3 into which combustion air is fed at 28 to produce a fuel air mixture characterised in that the diverging part of the air nozzle 3 includes at least two groups 34, 34' of slots or bores 4, 4' through one group 34' of which combustion air is supplied from low load to full load, the second group 34 supplying air only from an intermediate load to full load. The air flow is controlled by throttle valves 8, 10. Exhaust gas controlled by a valve 17 is recirculated. <IMAGE> |
