  • Patent number: 8596252
    Abstract: While an engine (10, 10A, 10B, 10C, 10D, 10E) is operating, a control system (22) processes data for certain engine operating parameters to calculate a quantity of exhaust gas needed to satisfy an exhaust gas recirculation requirement. If a primary EGR control loop (34) alone can satisfy the calculated quantity of exhaust gas, a secondary EGR control loop (36) is closed while the primary EGR control loop is controlled to satisfy the calculated quantity. When the processing determines that the primary EGR control loop alone cannot satisfy the calculated quantity, the secondary EGR control loop is open concurrently with the primary EGR control loop and both the primary EGR loop and the secondary EGR loop are controlled to cause the combined flow of exhaust gas through the primary EGR control loop and flow of exhaust gas through the secondary EGR control loop to satisfy the calculated quantity.

  • Patent number: 7287378
    Abstract: A flow including air and exhaust gas is received at a boost pressure at a plurality of cylinders (103). Exhaust gas is expelled from a first subset of the plurality of cylinders (103) into a first divided exhaust manifold (103). Exhaust gas is expelled from a second subset of the plurality of cylinders into a second divided exhaust manifold (111). The first subset and the second subset are different. An exhaust gas recirculation (EGR) system receives at an EGR inlet (131 or 201 and 211) a part of the exhaust gas from the first divided exhaust manifold (109) and a part of the exhaust gas from the second divided exhaust manifold (111).

  • Publication number: 20050071474
    Abstract: The data link layer maintenance system executes in the Q.921 protocol server of the serving ISDN Access Node and maintains the data link layer active in the ISDN-based Terminal Equipment and the Q.921 protocol server of the serving ISDN Access Node during the execution of a software reset process. This is accomplished by the Q.921 protocol server of the serving ISDN Access Node software storing the data communications connection data in a persistent table that survives the software reset operation. A predetermined set of control signals is then exchanged between the Q.921 protocol server of the serving ISDN Access Node and the ISDN-based Terminal Equipment in response to the initiation of a software reset process to execute standard signaling processes of the LAP-D protocol to force the Terminal Equipment and the Q.921 protocol server of the serving ISDN Access Node into a predetermined stable state.
