Abstract
1511906 Exhaust gas recirculation in IC engines REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 8 May 1975 [16 May 1974] 19505/75 Heading F1B Exhaust gas is recirculated, without passage through a valve, to an I.C. engine induction pipe 2a, air being admixed therewith before admission to the conduit in such a way as to control the flowrate of the exhaust gas. Exhaust gas from exhaust manifold 3a flows via pipe 6a to a point 8a immediately upstream of throttle valve 4a when in its substantially closed position, air being admitted to the pipe 6a by way of a pipe 9a and a valve device 10a. A vacuum chamber 14a is connected to the inlet pipe 2a via an electromagnetic valve 18, when a temperature sensitive switch 26 is open (i.e. at normal engine operating temperature) and, when switch 26 is closed (during warming up), is connected via the valve 18 to a vacuum reservoir 21. With the throttle valve 4a substantially closed, the vacuum downstream thereof or in the reservoir 21 holds valve 11a of valve device 10a fully open so that air-flow through pipe 9a is as high as possible and therefore, exhaust gas flow via pipe 6a is as low as possible. Below normal operating temperature, switch 26 is closed and valve 11a is held wide open for all settings of the throttle valve 4a by vacuum in reservoir 21 acting in chamber 14a. The air flow-rate is thus a maximum for the particular setting of the throttle valve and correspondingly the exhaust gas flow-rate is a minimum. When normal operating temperature is reached, switch 26 opens, so that chamber 14a is connected to pipe 2a and the opening of valve 11a is dependent upon throttle opening, being gradually reduced as the throttle 4a is opened. With the throttle 4a in its idling position, the pressure drop from 16a to 8a is small so that air-flow is small and exhaust gas recirculation is only moderate. Opening throttle 4a so that its edge crosses the opening at 8a increases the pressure drop and, therefore, the air flow-rate through pipe 9a reaches a maximum and the proportion of exhaust gas in the mixture entering induction pipe 2 is relatively low. Further opening of the throttle 4a causes the opening of the valve 11a to be reduced so reducing the air flowrate and increasing the exhaust gas recirculation. In Fig. 1 (not shown), the reservoir 21 and electromagnetic valve 18 are omitted so that the apparatus behaves throughout in the way that that shown in Fig. 2 does at normal engine operating temperatures.
