<p>A control system for an internal combustion engine comprises a valve 22 for controlling E.G.R. in dependence on the intake air flow rate, a fuel metering device 11 for controlling the fuel supply to the combustion chambers in dependence on the oxygen content of the exhaust gas, and a control 19, 20 for adjusting the ignition timing in dependence on the detection of knocking by sensors 21. The device 11 is responsive to signals from an air flow meter 12, an oxygen probe 15 and an engine speed sensor 35 to control the fuel supply to injectors 10. The knock sensor 21 control the timing of the sparking of plugs 17 via a distributor 18 and an advance-retard mechanism 19. An after burner 9 reduces NOx, HC and CO in the exhaust gas and a swirl generator (not shown) is provided in the intake manifold to maintain a constant swirl independently of comburant flow rate and engine speed. <IMAGE></p> |
