    • PROBLEM TO BE SOLVED: To provide a fuel injection quantity control device performing learning control of fuel injection quantity capable of defining an appropriate learning value for fuel injection pressure over a wide range, especially for high fuel injection pressure while eliminating driver's sense of incongruity due to combustion noise generated at a time of learning control, and an internal combustion engine provided with the control device.
      SOLUTION: The fuel injection quantity control device performs single injection for learning control after raising rail pressure to a learning subject rail pressure higher than the current rail pressure by driving a high pressure fuel pump 4 (ST4) if background noise (engine noise and road noise) is relatively high (ST2, Yes) when pilot injection quantity learning control execution conditions are satisfied. On the other hand, the fuel injection quantity control device performs single injection for learning control after the rail pressure drops to the learning subject rail pressure lower than the current rail pressure if background noise (engine noise and road noise) is relatively low.

    • PROBLEM TO BE SOLVED: To solve the problem that an improvement by swirl change is hindered due to generation of torque step difference in swirl change in the well-knowen technique of increasing torque by changing swirls sucked into a cylinder.
      SOLUTION: When an ON-counter is counted up at injection timing after a swirl changing switch is put ON, a torque step difference fuel correction value ΔQ determined from a map is added to reference injection quantity for moderating control at the time When an OFF-counter is counted up at injection timing after the swirl changing switch is put OFF, the torque step difference fuel correction quantity ΔQ determined from the map is added to the reference injection quantity for moderating control at the time. The injection quantity at the injection timing when the torque step difference is generated is thus corrected for the part of the torque step difference, so that generation of the torque step difference by swirl change can be restricted. As a result, swirl change difference can be enlarged, thereby engine performance can be greatly improved.

    • 要解决的问题:为了解决由于通过改变吸入气缸中的涡流而增加转矩的知名技术中的涡流变化产生转矩阶差而阻碍涡流变化的改善的问题。 解决方案:在旋转切换开关置于ON之后,当在喷射正时对ON计数器进行计数时,将从地图确定的转矩阶差差燃料校正值ΔQ加到基准喷射量中, 计数器在旋转切换开关置于OFF之后的喷射正时计数,将根据地图确定的转矩阶差差燃料校正量ΔQ加到用于调节控制的基准喷射量中。 因此,在转矩阶差的一部分中,对产生转矩阶差的喷射正时的喷射量进行修正,从而可以限制通过涡流变化产生转矩阶差。 结果,可以扩大涡流变化差,从而可以大大提高发动机的性能。

    • PROBLEM TO BE SOLVED: To provide a fuel injection timing control device capable of restraining a sudden change in the final target injection timing, even if a time lag is caused between the calculation timing of the basic target injection timing and the calculation timing of its correction value.
      SOLUTION: An electronic control device calculates the basic target injection timing of fuel to an engine from a fuel injection valve with every specific time (the timing t3 and t6), and calculates the final target injection timing by correcting the basic target injection timing by a correction value (a gradually changing factor) every time when a crankshaft rotates by a specific angle, and controls fuel injection from the fuel injection valve on the basis of the final target injection timing. The electronic control device calculates the gradually changing factor every time when the crankshaft rotates by the specific angle (the timing t1, t2, t4 and t5), and sets a factor corresponding to the calculation timing (the timing t3) of the basic target injection timing among these gradually changing factors, as a gradually changing factor used for calculating the final target injection timing up to the timing t6 for calculating the next time basic target injection timing.
