摘要： An internal combustion engine having an engine block for internal combustion, a high-pressure (HP) turbocharger for delivering pressurized intake air to the engine block, a low-pressure (LP) turbocharger for delivering pressurized intake air to the HP turbocharger, a turbogenerator for recovering heat energy from the exhaust gas downstream of the LP turbocharger to generate electricity, and an exhaust gas recirculation (EGR) system comprising an EGR-pump drawing exhaust gas from an EGR inlet located downstream of the turbogenerator, wherein the EGR-pump controllably delivers exhaust gas to an EGR mixer in the pressurized intake air stream at a location between the LP turbocharger and HP turbocharger. An electronic control unit (ECU) is adapted to command the EGR-pump to deliver a desired EGR flow-rate to the engine block based on look-up tables and either open-loop and/or closed-loop control algorithms.

摘要： In a predetermined exhaust gas recirculation (“EGR”) region, an exhaust gas recirculation control device performs control to recirculate a portion of exhaust gas of an internal combustion engine to a suction passage through an EGR passage in which an EGR valve is provided. If it is detected that a fuel cut recovery condition is satisfied after a fuel cut condition is satisfied, the EGR valve is closed from when the fuel cut recovery condition is satisfied until fuel gas is detected in an exhaust gas passage that leads from a combustion chamber to an inlet of the EGR passage.

摘要： In the engine including an MPL-EGR system having an HPL-EGR mechanism 6 and an LPL-EGR mechanism 7, a pressure difference between upstream side pressure and downstream side pressure of a low pressure EGR cooler 73 provided in the LPL-EGR mechanism 7 is detected by a pressure difference sensor 89. When an actual pressure difference value detected is higher than a reference pressure difference value in a state where no blocking occurs in the LPL-EGR mechanism 7, and the deviation amount therebetween reaches a predetermined amount, it is determined that the blocking occurs in the inside of the low pressure EGR cooler 73. In contrast, when the actual pressure difference value detected is lower than the reference pressure difference value, and the deviation amount therebetween reaches a predetermined amount, it is determined that the blocking occurs in the inside of the pipe members 74 and 75 except the low pressure EGR cooler 73.

摘要： The present invention makes it possible to accurately determine an EGR rate from an in-cylinder pressure. An EGR rate determination method for an internal combustion engine according to the present invention, a combustion period is calculated by using in-cylinder pressure data measured by an in-cylinder pressure sensor. An in-cylinder flame velocity is then calculated from the combustion period. Next, in accordance with prepared data indicative of the influence of an engine speed on the flame velocity, a portion of the flame velocity calculated from the combustion period that is affected by the engine speed is eliminated. Eventually, a current EGR rate is determined from the flame velocity from which the portion affected by the engine speed is eliminated.
