    摘要: The invention provides a fuel injection control device for an internal combustion engine that can improve the accuracy of combustion control regarding smoke suppression. The fuel injection control device is applied to an engine provided with an EGR device for returning, as a part of an intake gas flown into the cylinder, an EGR gas, withdrawn from an exhaust passage, to an air intake passage. The amount of oxygen OXM contained in the intake gas and the concentration of oxygen OXC contained in the intake gas are detected (steps S1 and S2). The smoke tolerable limit value QOXMLMT as the upper limit of the amount of fuel injection; which can suppress the amount of smoke generated in the engine to a predetermined tolerance range, is set based on the detected amount of oxygen and concentration of oxygen (step S4), and, when the required amount of injection QDMD determined based on operation conditions is larger than the tolerable limit value QOXMLMT, the instructional injection amount QFIN is limited to the tolerable limit value QOXMLMT.

    摘要: A technique is provided which, in an exhaust gas recirculation apparatus for an internal combustion engine, can calculate a low-pressure EGR rate and a high-pressure EGR rate in an accurate manner, and control the flow rates of both a low pressure EGR passage and a high pressure EGR passage in a closed-loop control manner, thereby to make the temperature of intake air and a supercharging pressure stable and to suppress the deterioration of exhaust emissions as well as the deterioration of power performance. The low pressure EGR rate, representative of the proportion of an amount of low pressure EGR gas to an amount of intake air sucked into the internal combustion engine, and the high pressure EGR rate, representative of the proportion of an amount of high pressure EGR gas to the amount of intake air, are calculated by using a CO2 concentration in an intake passage at a location downstream of a connection portion of the low pressure EGR passage and upstream of a connection portion of the high pressure EGR passage, a CO2 concentration in the intake passage at a location downstream the connection portion of the high pressure EGR passage, and a CO2 concentration of an exhaust gas discharged from the internal combustion engine (S103). The low pressure EGR rate and the high pressure EGR rate to be calculated are controlled to individual target values, respectively (S104).

When it is determined that the internal combustion engine is under a predetermined low-temperature environment, the low-pressure EGR valve is kept closed while the internal combustion engine is in the fuel-supply cutoff operation mode.
