An internal combustion engine includes a fuel injection valve that injects fuel into a combustion chamber and an ignition plug that ignites an air-fuel mixture in the combustion chamber. A control device of the internal combustion engine includes an electronic control unit configured to, when a cold-starting of the internal combustion engine is started, execute a plurality of fuel injections into each cylinder in one cycle, after the cold-starting of the internal combustion engine is started, retard a timing of an ignition by the ignition plug in each cylinder, and after the timing of the ignition by the ignition plug is retarded, decrease the number of fuel injections into each cylinder in one cycle according to the retardation of the ignition timing by the ignition plug.

Control device of internal combustion engine

A control device that controls an internal combustion engine includes an electronic control unit configured to, during an operation other than a start-up of the internal combustion engine, cause the fuel injection valve to execute one or a plurality of fuel injections in each cycle such that a target fuel injection amount in one injection becomes equal to or greater than a predetermined minimum injection amount, and when the internal combustion engine is started up, in a case where startability of the internal combustion engine is insufficient, execute an excess split injection control for causing the fuel injection valve to execute more fuel injections than the maximum number of fuel injections per cycle while making the target fuel injection amount in one injection smaller than the minimum injection amount per cycle and maintaining a target total fuel injection amount per cycle.

An operating range boundary for switching a cam for driving an intake valve (drive cam) is changed in a direction of decreasing an engine load if a target EGR rate is predicted to increase across the contour line of the EGR rate. By changing the boundary, the drive cam is switched from a large cam to a small cam before an operating point is transferred from a partitioned range with a low target EGR rate to a partitioned range with a high target EGR rate.

Control device for internal combustion engine

An electronic control unit is configured to select a first cam as a driving cam of an intake valve in a first operation range where a target value of an EGR rate is set to a specified EGR rate, and is configured to select a second cam as the driving cam in a second operation range smaller in valve duration and lift amount than the first cam. Accordingly, in most of the operation regions, the first cam is selected, and the second cam is selected only in a high-torque and high-speed region. When the second cam is selected in the high-torque and high-speed region, the state where an actual compression ratio is high can be eliminated, and suction efficiency can be decreased. Therefore, decrease in a knocking limit can be suppressed.

Vapor phase growth apparatus and vapor phase growth method

An objective of the present invention is to stabilize the fuel injection amount for each cylinder and to execute fuel injection control accurately in a single-pressure-feed dual-injection type alcohol fuel injection system. An engine includes two injection valves and and a single-pressure-feed dual-injection type fuel supply system. The fuel supply system is configured such that fuel is injected sequentially in two cylinders during the pressure-feed-interval period from the execution of one fuel pressure-feed operation to the execution of the next fuel pressure-feed operation. If the alcohol concentration in the fuel is higher than a predetermined determination value &#x3b3; at a startup operation time, an ECU executes only a cylinder injection for the first of the two cylinders described above, and executes both an intake passage injection and a cylinder injection for the second cylinder. Thus, even if the fuel pressure decreases due to the fuel injection for the first cylinder, the required fuel injection amount can be reserved for the second cylinder.

The control apparatus includes an ECU. The ECU is configured to execute a divided injection control to inject fuel from the fuel injection valve by a plurality of partial lift injections. The ECU is configured to execute a division number reduction control when the value of a spray shape parameter representing spray shape fluctuation is greater than a division number reduction determination value. The division number reduction control is control to reduce the number of partial lift injections in one engine cycle and to lengthen an injection time of each of the partial lift injections.
