Abstract (en)
[origin: WO2011050920A1] Disclosed is a method for the control and regulation of an internal combustion engine (1), comprising an independent common rail system on the A-side and an independent common rail system on the B-side. During normal operation, the rail pressure (pCR(A), pCR(B)) is controlled in each common rail system via a low pressure-side suction throttle (4A, 4B) as the first pressure-adjusting element in a rail pressure control loop and, at the same time, the rail pressure (pCR(A), pCR(B)) is subjected to a rail pressure disturbance variable via a high pressure-side pressure control valve (11A, 11B) as a second pressure-adjusting element, by means of which a pressure control valve volume flow is redirected via the high pressure-side pressure control valve (11A, 11B) from the rail (6A, 6B) into a fuel tank (2). The method is characterized in that a first emergency operation is implemented for the common rail system in question when a defective rail pressure sensor (8A, 8B) and a non-defective pressure control valve (11A, 11B) have been detected in said common rail system, while a second emergency operation is implemented for the common rail system in question when a defective rail pressure sensor (8A, 8B) and simultaneously a defective pressure control valve (11A, 11B) have been detected in said common rail system, and wherein the normal operation is implemented for the other, non-defective common rail system.
