摘要： In an exhaust gas sensor control system and control method, the exhaust pipe wall temperature is estimated based on the measured exhaust gas temperature measured, the exhaust gas flowrate, and the measured outside air temperature, with reference to a supplied heat quantity calculation map (94), wall temperature added value map (95), and a wall temperature subtracted value map (96). Then the dew-point of the exhaust pipe is calculated based on the air-fuel ratio of the air flow amount to the weight of fuel, and a condensed water added amount is calculated based on the relative wall temperature and the exhaust gas flow amount. The amount of condensed water is then estimated by summing the calculated condensed water added amounts.

摘要： In one embodiment, a total pilot injection amount is calculated from the difference between a compressed gas temperature in a cylinder and a fuel self-ignition temperature. As pilot injection, a plurality of instances of divided pilot injection are performed, and by setting the injection amount per one instance of divided pilot injection to an injector minimum limit injection amount, each divided pilot injection amount is suppressed, and the penetration of fuel is suppressed to a low level so that attachment of fuel to a wall face is avoided, and also, fuel is caused to accumulate in the center portion of the cylinder.
摘要翻译：在一个实施例中，根据气缸内的压缩气体温度和燃料自燃温度之间的差来计算总引燃喷射量。作为引燃喷射，进行多个分割引燃喷射的实例，并且通过将每一个分割引燃喷射的喷射量设定为喷射器最小极限喷射量，每个分割的引燃喷射量被抑制，并且燃料的渗入量抑制到低水平，从而避免燃料附着到壁面，并且使燃料积聚在气缸的中心部分。

摘要： An exhaust gas control system for an internal combustion engine includes a turbocharger that includes a compressor arranged in an intake passage, and a turbine arranged in an exhaust passage; a low-pressure EGR unit that recirculates a portion of exhaust gas back to the internal combustion engine through a low-pressure EGR passage that provides communication between the exhaust passage, at a portion downstream of the turbine, and the intake passage, at a portion upstream of the compressor; a low-pressure EGR valve that is provided in the low-pressure EGR passage, and that changes the flow passage area of the low-pressure EGR passage; and a valve control unit that executes an opening/closing control over the low-pressure EGR valve. 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.

摘要： In one embodiment, a determination is made of whether or not in a condition in which a compressed gas temperature will reach a fuel self-ignition temperature by only a compression operation in the compression stroke, and in a case where the compressed gas temperature will reach the fuel self-ignition temperature, pilot injection is judged to be unnecessary, so this pilot injection is prohibited.
