摘要： After an engine stopping operation, nozzle vanes (10) provided in a variable nozzle-type turbocharger (4) are displaced toward a closed side for the purpose of reference position determination of the vanes (10) for the next engine operation. The displacement of the nozzle vanes ( 10) is performed after it is determined that the engine has stopped rotating. Therefore, the control apparatus prevents an undesired event where the flow speed of exhaust gas blown onto a turbine wheel (6) becomes excessively great, so that the overspeed rotation of the turbocharger (4) occurs and a malfunction results.

摘要： An allocation map stored in a ROM in an ECU is set corresponding to the kinds of fuel injection valves. Therefore, at the time of incorporating fuel injection valves into a diesel engine, it is possible to freely set how injection correction amount data read from a two-dimensional code by a writing device is allocated in an injection correction amount map in steps S214 and S216, separately for the individual kinds of fuel injection valves. Since the injection correction amount map in which the injection correction amount data is arranged with a distribution of density corresponding to the kinds of fuel injection valves, it is possible to change and set correction points with high degree of freedom even though the amount of data recordable in the two-dimensional code is limited. Therefore, high-precision data maps can be used separately for the individual kinds of fuel injection valves.
摘要翻译：存储在ECU中的ROM中的分配图被设置为与燃料喷射阀的种类相对应。因此，在将燃料喷射阀并入柴油发动机时，可以自由地设定在步骤S214和S216中如何在喷射校正量图中分配由写入装置从二维码读取的喷射校正量数据分别用于各种燃油喷射阀。由于喷射校正量数据以与燃料喷射阀的种类相对应的密度分布布置的喷射校正量图，因此即使可记录的数据量也可以高度自由地改变和设定校正点在二维码是有限的。因此，高精度数据图可以分别用于各种燃油喷射阀。

摘要： A fuel injection control apparatus has a rail pressure sensor (43) and an electronic control unit (ECU) (52). The ECU (52) converts the common rail pressure (analog signal) detected by the rail pressure sensor (43) into a digital signal by an A/D converter (53, 55), and controls the injection amount and the injection pressure based on the converted rail pressure. During the injection amount control, the ECU (52) determines an injection period based on an injection amount instruction value and the rail pressure, and causes an injector (23) to inject fuel over the injection period. During the injection pressure control, the ECU (52) controls a supply pump (27) so that the rail pressure converges to a target pressure. Furthermore, the ECU (52) performs the sampling for computing a rail pressure for the injection amount control and the sampling for computing a rail pressure for the injection pressure control at different timings.
