    摘要: There are provided a control system and method and an engine control unit for an internal combustion engine, which are capable of determining an amount of fuel to be injected during a two-stage fuel injection combustion mode and a duration period of this mode such that stable combustion and smooth transition between combustion and smooth transition between combustion modes are ensured. The control system includes an ECU and a crank angle sensor. The ECU calculates a demanded torque PME demanded of the engine, and determines which of the homogenous combustion mode, the stratified combustion mode, and the two-stage fuel injection combustion mode should be selected as the combustion mode of the engine, based on the demanded torque PME. The ECU determines an injection time period ToutD during the compression stroke in two-stage fuel injection combustion mode based on the engine rotational speed.

    摘要: There is disclosed a fuel injection control system for an internal combustion engine, which is capable of properly determining fuel injection timing such that the fuel injection timing reflects behaviors of injected fuel, thereby improving drivability and fuel economy. The internal combustion engine of an in-cylinder fuel injection type is operated while switching between a stratified combustion mode in which fuel injection into each cylinder is performed during a compression stroke and a homogenous combustion mode in which the fuel injection into the cylinder is performed during an intake stroke. The fuel injection control system controls fuel injection timing. A required fuel injection time is determined based on detected operating conditions of the engine. A direct ratio and a carry-off ratio are determined based on the operating conditions of the engine. The required fuel injection time is corrected by using the direct ratio and the carry-off ratio, whereby a final fuel injection time period is determined. Based on the engine rotational speed and the final fuel injection time period, the fuel injection timing is determined.

    摘要: There is provided an element mapping unit, scanning transmission electron microscope, and element mapping method that enable to acquire an element mapping image very easily. On the scanning transmission electron microscope, the electron beam transmitted through an object to be analyzed enters into the element mapping unit. The electron beam is analyzed of its energy into spectrum by an electron spectrometer and an electron energy loss spectrum is acquired. Because the acceleration voltage data for each element and window data for 2-window method, 3-window method or contrast tuning method are already stored in a database and accordingly the spectrum measurement is carried out immediately even when an element to be analyzed is changed to another, the operator can confirm a two-dimensional element distribution map immediately. Besides, because every electron beam that enters into an energy filter passes through the object point, aberration strain in the electron spectrometer can be minimized and higher energy stability can be achieved. As a result, drift of the electron energy loss spectrum acquired by analyzing the electron beam into spectrum can be minimized and element distribution with higher accuracy can be acquired.
