Abstract
A fuel injection system for an engine is configured of a downstream-side fuel injection valve which is provided to an intake passage connected to a combustion chamber, and from which fuel in the intake passage is injected, and an upstream-side fuel injection valve which is provided in the intake passage upstream of the downstream-side fuel injection valve, and from which fuel in the intake passage is injected. In the fuel injection system, a fuel injection pressure applied to the upstream-side fuel injection valve is set at a higher value than a fuel injection pressure applied to the downstream-side fuel injection valve. Fuel is injected from both injection valves on fuel injection shares depending on a detected load on the engine.
