ABSTRACT:
A communication passage connects a first fuel passage connected to a fuel injection valve of a multi-cylinder internal combustion engine corresponding to a cylinder which is to be fired earlier, to a second fuel passage connected to a fuel injection valve corresponding to another cylinder which is to be fired later, at locations in the vicinity of the outlet ports of corresponding delivery valves arranged across the respective fuel passages. A selector valve selectively connects the delivery valve in the first fuel passage with the fuel injection valve corresponding to the first fuel passage or with the communication passage, so that when the engine is operating in a low load and low speed region, part of the cylinder alone is operated and at the same time fuel is allowed to flow in a sole direction from the first fuel passage to the second fuel passage via a one-way valve, to thereby effect a VIGOM injection.
