摘要： A fuel injection control device performs fuel injection only once corresponding to an over-rich air/fuel ratio immediately after the end of F/C as rich air/fuel ratio control after F/C. Such fuel injection is performed with a fuel amount which is the sum of a fuel amount corresponding to a shallow rich air/fuel ratio AFrich and a predetermined increment. Immediately after this operation, fuel injection is performed with a fuel amount corresponding to the shallow rich air/fuel ratio AFrich. This adjusts the air/fuel ratio of the engine to the over-rich air/fuel ratio for an extremely short period of time immediately after the end of F/C, following which the air/fuel ratio is immediately switched to the shallow rich air/fuel ratio AFrich.

摘要： The valve timing is changed to increase the internal EGR amount the moment a fuel cut process begins (FIG. 2C). Before a sufficient amount of internal EGR is obtained, control is exercised so that the throttle-opening angle TA is larger than a basic idle-opening angle TA0. When a sufficient amount of internal EGR is obtained, control is exercised so that the throttle-opening angle TA is smaller than the basic idle-opening angle TA0 (FIG. 2D). The increase in the internal EGR amount is rendered smaller during fuel cut at a low rotation speed than during fuel cut at a high rotation speed. In addition, the amount of decrease in the throttle-opening angle TA is rendered smaller during fuel cut at a low rotation speed than during fuel cut at a high rotation speed.

摘要： An upstream-side catalyst is arranged in an exhaust passage and a downstream-side catalyst is arranged in the exhaust passage downstream of the upstream-side catalyst. An air-fuel ratio sensor is attached for detecting the air-fuel ratio in the exhaust passage between the upstream-side catalyst and downstream-side catalyst. A representative upstream-side stored oxygen value OXU is calculated based on whether the control state of the engine is the “slight rich” control, “slight lean” control, fuel increase correction, or engine fuel cut and a representative downstream-side stored oxygen value OXD is calculated based on the engine control state and the output of the air-fuel ratio sensor. If the representative upstream-side stored oxygen value OXU or the representative downstream-side stored oxygen value OXD becomes smaller than the corresponding allowable lower limit LLU or LLD, “slight lean” control is performed, while if it becomes larger than the corresponding allowable upper limit ULU or ULD, “slight rich” control is performed.

摘要： An ignition timing control device including a mass flow meter arranged in the intake passage. At the time engine warmup, at high load operation where the mass flow rate of the intake air is higher than the reference value, the ignition timing is made a basic ignition timing for engine warmup. As opposed to this, in medium load operation, where the mass flow rate of the intake air is lower than the reference value, the ignition timing is retarded from the basic ignition timing of engine warmup. When the atmospheric pressure falls, the reference value is lowered.

摘要： A valve timing control device for an internal combustion engine. The device comprises first determination means for determining a first optimal value of the valve overlap period in the current engine operating condition, on the basis of the current engine speed and load, second determination means for determining a second optimal value of the valve overlap period in the current engine operating condition by reducing the first optimal value when the engine has not warmed up, and valve overlap period control means for controlling a valve overlap period using the first optimal value, or such that it varies gradually from the second optimal value to the first optimal value, when the current degree of opening of the throttle valve is larger than a predetermined value, even if the engine has not warmed up. A back-flow of exhaust gas does not occur when the degree of the throttle valve is relatively large so that the valve overlap period at this time is made larger and a higher engine torque can be obtained to increase the trapping efficiency and the scavenging efficiency, even if the engine has not warmed up.
