Abstract: A fuel injection controller of an in-cylinder injection engine determines that a combustion state has deteriorated and executes a split injection for injecting fuel in split amounts into each cylinder in multiple injection events in a cycle of the cylinder if it is determined that a combustion fluctuation is greater than a predetermined determination value during operation of the engine. The fuel injection controller increases a ratio of an injection amount of the first injection event in the split injection and lengthens an injection interval between the injection events as the combustion fluctuation increases. Thus, a wet amount of the injected fuel is reduced to expedite atomization of the injected fuel and to homogenize an in-cylinder mixture gas. As a result, the combustion state is improved.

Abstract: A throttle control system includes a valve, an electric throttle unit, a control unit, a throttle sensor, a memory device, and a memory execution unit. The throttle control system operates the memory execution unit to allow the memory device to store an opening signal detected by the throttle sensor as a “detected full opening” of the valve, when energization of the electric throttle unit is stopped by the control unit and the valve stops at a “mechanical full opening” by mechanical operation. Thus, it becomes possible to coincide the actual valve opening of the valve and a “control valve opening” which the control unit recognizes. Therefore, it becomes possible to decrease system variation between the electric throttle unit and the control unit. Moreover, a control accuracy of an air intake amount by the throttle control system can be improved.

Abstract: An internal combustion engine (1) causes an air/fuel mixture in a cylinder to combust due to ignition by a spark plug (14). The engine controller (50) calculates a crank angle at knock on the basis of an operating state of the engine (1) (53–54), calculates a knock intensity on the basis of this crank angle at knock (54), calculates a limit ignition timing at which knock is not generated, on the basis of the knock intensity (54), and controls the ignition timing of the spark plug (14) to the limit ignition timing at which knock is not generated (55). Therefore, suitable control of the ignition timing is achieved, by means of a small number of adaptation steps.
