摘要： PROBLEM TO BE SOLVED: To enable highly accurate throttle opening control regardless of an engine operating range even when change in building-up deposits is generated in a throttle valve installing part.
SOLUTION: Based on a corresponding relation map MAPsbta between a throttle opening TA and an opening area with no deposit building up, the throttle opening TA is converted into a reference opening area SB (S106). By subtracting opening area variation dDS accompanied by change in building-up deposits from the reference opening area SB, an actual opening area SA after change in the building-up deposits is calculated (S108). Since the opening area variation dDS is not affected by a difference of the engine operation range, the actual opening area SA can be accurately calculated. By converting the actual opening area SA into a throttle opening TAa for control based on the corresponding relation map MAPsbta (S110), the throttle opening TAa for control highly accurately reflecting an actual opening area can be detected. This throttle opening TAa for control is used for control (S112, S114).

摘要翻译：要解决的问题：即使在节气门安装部件中产生积累沉积物的变化，也能够实现与发动机工作范围无关的高精度的节气门开度控制。解决方案：基于节气门开度TA和没有积存积分的开口区域之间的对应关系图MAPsbta，节气门开度TA被转换为基准开度区域SB（S106）。通过从参考开口区域SB减去伴随着建立沉积物的变化的开口面积变化dDS，计算建立沉积物变化后的实际开口面积SA（S108）。由于开口面积变化dDS不受发动机工作范围的差异的影响，所以可以精确地计算实际开口面积SA。通过将实际开口面积SA转换为基于对应关系图MAPsbta进行控制的节气门开度TAa（S110），可以检测用于高精度地反映实际开口面积的控制用节气门开度TAa。用于控制的节气门开度TAa用于控制（S112，S114）。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an intake control system for an internal combustion engine that can set an idle speed to a prescribed speed by detecting the cause of a variation in intake air quantity in an idle operation and learning the variation in intake air quantity according to the variation cause. SOLUTION: An ECU 40 executes feedback control of controlling an idle opening angle of a throttle valve 24 arranged in an intake passage 19 of an engine 10 to set an idle speed of the engine 10 to the prescribed speed.

摘要： PROBLEM TO BE SOLVED: To determine stability of engine operation quickly and accurately by improving accuracy of each index of operation stability of an internal combustion engine. SOLUTION: Engine speed fluctuation dtn and stability threshold value dx corresponding to engine operation range at this time are calculated (S102-S108), nondimensional combustion level Lfa is calculated by calculating ratio of the engine speed fluctuation dtn and the stability threshold value dx (S110). Consequently, drop of accuracy of the index due to change of engine operation range is prevented, each combustion level Lfa obtains accurately reflecting combustion stability under each operation condition, speed fluctuation integration value S/N which is integration of the combustion level Lfa becomes greater. Consequently, since determination can be done accurately even if a heavy fuel determination reference value is set small, deterioration in combustion stability due to heavy fuel can be determined quickly and accurately with a small integration number.
