摘要： A rotational phase difference of a camshaft relative to a crankshaft in a variable valve timing mechanism is controlled by an operation of an oil control valve. That is, in the oil control valve, there is outputted an operational signal which is defined by adding a feedback correction amount corresponding to a difference between an actual value and a target value of the rotational phase difference, to a holding learning value as the operational signal for holding the rotational phase difference. The holding learning value is altered only by a specified value on condition that the operational signal for holding the rotational phase difference is assumed to change.

摘要： In a lean burn control system for an internal combustion engine, when surging in the engine is caused due to lowering of an engine lean limit, a first correction circuit decreases a target air-fuel ratio irrespective of whether the system is operated under an open loop control or a feedback control. On the other hand, when the surging is caused due to variation in output characteristic of an air-fuel ratio monitoring sensor, a second correction circuit decreases the target air-fuel ratio only when the system is operated under the feedback control. Accordingly, the target air-fuel ratio as corrected by the first correction circuit is used in the open loop control, while the target air-fuel ratio as corrected by the first and second correction circuits is used in the feedback control.

摘要： It is determined whether the current operation condition is in a transitional or steady state. If the operation condition is in a transitional state, then the transition gain is obtained by multiplying the transition base gain that is calculated corresponding to engine speed with a map by a transition degree correction coefficient. If the operation condition is in a steady state, the steady-state gain is set to the steady-state gain that is calculated corresponding to the engine speed. Subsequently, the control magnitude OCVC of the oil pressure control valve is obtained by multiplying the difference between the target advance angle and the actual advance angle by the gain.

摘要： When fuel supply system abnormality diagnosis conditions are satisfied, the abnormality of a fuel supply system is diagnosed by comparing an air/fuel ratio deviation index value with a lean/rich abnormality determination value by diagnosis means. At this time, a hot lean abnormality determination value KHL is set leaner than an ordinary lean abnormality determination value KLL, and a hot rich abnormality determination value KHH is set richer than an ordinary rich abnormality determination value KLH by abnormality determination value setting means when the engine compartment temperature is high. As a result, it is possible to diagnose whether or not the fuel supply system is abnormal (i.e., an abnormal deviation in the air/fuel ratio) while preventing the mistake even when the engine compartment temperature is high, so that the early discovery of the abnormality and the prevention of the mistaken diagnosis are made compatible.
摘要翻译：当满足燃料供应系统异常诊断条件时，通过诊断装置比较空/燃比偏差指数值与贫/丰异常判定值来诊断燃料供给系统的异常。此时，将热稀薄异常判定值KHL设定为比普通稀薄异常判定值KLL更稀，并且当富含异常判定值KHH比普通浓异常判定值KLH更高于异常判定值设定单元时，发动机舱温度高。因此，即使在发动机室温度高的情况下也能够防止燃料供给系统异常（即，空气/燃料比的异常偏差），从而能够早日发现使异常和防止误诊得到兼容。

摘要： An apparatus capable of performing correct determination of a misfire limit without involving influence by differences between individual internal combustion engines, and thus capable of realizing highly precise lean control. During lean control, a mean deviation MD.sub..lambda.=1 of angular-velocity differences, which has been learned during the adoption of the stoichiometric air-fuel ratio (i.e., during .lambda.=1) in the relevant internal combustion engine, is subtracted from the current mean deviation MD.sub.L of angular-velocity differences occurring in the engine, so that the fuel injection amount is corrected in accordance with the resultant difference .DELTA.MD, which is attributable to an increase in the risk of misfire. Thus, the mean deviation component MD.sub..lambda.=1 which corresponds to the stoichiometric air-fuel ratio and which may differ between individual internal combustion engines, is eliminated, and only the component .DELTA.MD attributable to an increase in the risk of misfire is used to control the air-fuel ratio, thereby eliminating influence of differences between internal combustion engines to enable correct determination of a misfire limit.
摘要翻译：能够在不受各个内燃机之间的差异影响的情况下能够正确地确定失火极限的装置，从而能够实现高精度的精益控制。在精益控制期间，在相关内燃机中采用化学计量空燃比（即在λ= 1期间）期间学习的角速度差的平均偏差MDλ= 1，从在发动机中发生的角速度差的当前平均偏差MDL，使得燃料喷射量根据由此导致的失火风险增加导致的差ΔTATA校正。因此，消除了对应于各个内燃机之间的理论空燃比对应的平均偏差分量MDλ= 1，并且仅使用归因于失火风险增加的分量DELTA MD 控制空燃比，从而消除内燃机之间差异的影响，从而能够正确确定失火极限。
