ABSTRACT:
An internal combustion engine comprising a fuel injector for injecting fuel directly into a cylinder and a calculating device for calculating a calculated amount of fuel to be injected on the basis of an engine operating state. The fuel injector injects all of the calculated amount of fuel during a compression stroke when the calculated amount of fuel is smaller than a predetermined first amount of fuel, and injects a part of the calculated amount of fuel during an approximately first half of an intake stroke and injects a remaining part of the calculated amount of fuel during a compression stroke when the calculated amount of fuel is equal to or larger than a predetermined second amount of fuel which is larger than the predetermined first amount of fuel.
