摘要： PROBLEM TO BE SOLVED: To smoothly start an internal combustion engine having an injector for cylinder injection and an injector for intake passage injection.
SOLUTION: When starting the engine having the injector 110 for the cylinder injection and the injector 120 for the intake passage injection, a danger of preignition (excessively early ignition) in an initial time compression stroke is determined on the basis of a turning angle of a crankshaft 200 when stopping the engine last time. When the danger of preignition is high, fuel injection from the injector 110 for the cylinder injection set so that the air-fuel ratio in a combustion chamber 107 falls out of an ignitable range (so as to be made overrich), is additionally performed in addition to fuel injection from the injector 120 for the intake passage injection for ordinary engine starting.

摘要： PROBLEM TO BE SOLVED: To provide an air conditioning system controller for preventing upwash of an engine by switching the presence/absence of a liquid pool processing.
SOLUTION: Only when there is no history that an estimation torque is not less than 2 [Nm] in a compressor of an air conditioning system (NO in a step S11), the liquid pool processing is performed with respect to liquefaction of a refrigerant in the compressor (step S13). Accordingly, during the operation of the air conditioning system, the liquid pool processing is performed when a liquid pool might be generated. When the compressor has already performed the normal processing, and there is no need for the liquid pool processing, an initial operation processing is performed (step S14). Therefore, the upwash of the engine can be prevented when the liquid pool is generated.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine ignition timing control device capable of effectively suppressing rotation fluctuation by enabling high response ignition timing feed back control.
SOLUTION: The ignition timing control device re-calculates an ignition timing feed back control correction quantity θfb and final ignition timing (S112) when it is determined that re-calculation process is executable during a period from the timing of the regular calculation of the final ignition timing until the final ignition timing (yes in S108, yes in S110). Since engine speed NE at timing closer to actual ignition timing is reflected to the final ignition timing, overshoot does not easily occurs even if a feed back gain is increased, high response ignition timing feed back control is enabled and engine speed fluctuation can be effectively suppressed. When re-calculation process is not executed (no in S108, no in S110), accuracy at the final ignition timing is maintained to some extent and abnormal ignition such as a misfire does not occur since the final ignition timing based on the ignition timing feed back control correction quantity θfb calculated at a regular time is used (S102-S106).

摘要翻译：解决的问题：提供一种能够通过实现高响应点火正时反馈控制来有效地抑制旋转波动的内燃机点火正时控制装置。解决方案：当从正常计算的定时期间确定重新计算处理可执行时，点火正时控制装置重新计算点火正时反馈控制校正量θfb和最终点火定时（S112）的最终点火正时直到最终点火正时（S108中为是，S110为是）。由于在更接近实际点火正时的定时的发动机转速NE被反射到最终的点火正时，因此即使反馈增益增加也不容易发生过冲，能够有效地抑制高反应点火正时反馈控制和发动机转速波动。当不执行重新计算处理时（S108中为否，S110中为否），最终点火正时的精度在某种程度上保持不变，并且不会发生诸如失火的异常点火，因为基于点火正时进给的最终点火正时使用在常规时间计算出的后退控制校正量θfb（S102〜S106）。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To correctly detect any trouble of a flow rate sensor in a control device of a refrigeration cycle device having the flow rate sensor for detecting the refrigerant flow rate in a high-pressure side area to estimate the torque of a compressor based on the detected value of the refrigerant flow rate. SOLUTION: Deviation of the first estimated torque to be estimated from the flow rate of a refrigerant to be detected by a flow rate sensor 7 in the control device and the second estimated torque to be estimated by a method not using the refrigerant flow rate, is detected, and presence/absence of any trouble of the flow rate sensor 7 is determined based on the result of the detection of the deviation of the estimated torque.

Thus, the torque estimation accuracy of a compressor can be enhanced thereby. COPYRIGHT: (C)2010,JPO&INPIT
