    摘要: In a direct-injection internal combustion engine, a variable intake valve, of which valve timing can be varied, is used as an air intake valve through which an air intake path and a combustion chamber communicate with each other. The direct-injection internal combustion engine includes: a variable-intake-valve control section that controls the valve timing of the variable intake valve; and an intake-air temperature acquisition section that acquires a temperature of the intake air introduced into the combustion chamber. When the fuel is injected into the combustion chamber via a fuel injection valve during a compression stroke or an expansion stroke, if the acquired intake-air temperature is low, the closing timing of the variable intake valve is advanced, so that the actual compression ratio is increased.

    摘要: A direct cylinder fuel injection-type spark ignition internal combustion engine which executes a stratified charge combustion by vaporizing the fuel while flying after having been injected into the cylinder in the compression stroke to form a mixture in a portion in the cylinder, and by igniting and burning the mixture by positioning the spark gap of a spark plug in the mixture at the ignition timing before the compression top dead center, wherein when the fuel is required in an increased amount and the air-fuel ratio of the mixture formed by the fuel injected by the first fuel injection near the ignition timing becomes too rich, part of the required amount of fuel is injected by a second fuel injection in the compression stroke separately from the first fuel injection and when the amount of fuel injected by the second fuel injection becomes larger than a preset amount, the second fuel injection is brought to the side in advance of the first fuel injection and when the amount of fuel injected by the second fuel injection becomes smaller than the preset amount, the second fuel injection is brought to the side delayed behind the first fuel injection.
