摘要： PROBLEM TO BE SOLVED: To provide a control device of an internal combustion engine capable of contributing to reduction in a toxic component in exhaust gas and combustion noise, by accurately determining a cylinder of reducing the swirl ratio, in a control device of an internal combustion engine. SOLUTION: The suction air volume in a state of stopping operation of an intake valve of a #1 cylinder, is stored as the suction air volume Ga 1 except for one cylinder of the #1 cylinder. An each cylinder suction air volume reducing quantity ΔGa 1 of the #1 cylinder is calculated by reducing this Ga 1 from the reference suction air volume Ga 0 . An each cylinder suction air volume reducing quantity ΔGa is similarly calculated on the other cylinder. The each cylinder suction air volume reducing quantity ΔGa can be said as the air volume flowing in its cylinder or its correlation value. The swirl ratio reduces as the air volume flowing in the cylinder increases. Thus, a determination is made that the swirl ratio reduces as the cylinder being large in the each cylinder suction air volume reducing quantity ΔGa. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To make EGR converge to a target value quickly and stably even if an operation condition changes variously in an internal combustion engine using external EGR and internal EGR in parallel, in relation to an EGR control device for the internal combustion engine.
SOLUTION: Quantity of internal EGR is controlled by making magnitude of negative valve overlap in which both of an intake valve and an exhaust valve close variable. EGR is feedback-controlled by controlling opening of EGR valve and adjusting external EGR quantity to make intake air quantity correlating to EGR quantity coincide with the target value. As magnitude of the negative valve overlap is larger, feedback gain in feed back of deviation between intake air quantity and the target value to EGR valve opening is made larger.

摘要： PROBLEM TO BE SOLVED: To improve a degree of freedom of air-fuel ratio control after completing warming-up, in an internal combustion engine capable of using fuel mixed with not only gasoline but also oxygen-containing fuel such as alcohol or the oxygen-containing fuel such as gasoline and alcohol.
SOLUTION: When warming-up of the internal combustion engine is not completed (No in Step S102), target oil pressure Pt set based on the alcohol concentration Ce acquired in a Step S103, is compared with present oil pressure Pn acquired in a Step S105 (Step S106). When Pn>Pt is realized, oil pressure of the internal combustion engine is controlled so as to become Pn=Pt. Thus, since quantity of oil returning to an oil pan increases, agitation of the oil in the oil pan is promoted.
