Claim Text:
1. A control unit for an internal combustion engine, the engine comprising a direct injector directly injecting fuel into a cylinder and a port injector injecting fuel into an intake port of the cylinder, the control unit comprising: a load detector to detect a load on the engine; an injection volume calculator to calculate a direct injection volume indicating a volume of the fuel injected from the direct injector; a first controller to perform a first control for increasing the frequency of the injection by the direct injector, upon a reduction in the cylinder injection volume; a second controller to perform a second control for increasing a port injection volume indicating a volume of the fuel injected from the port injector, upon a reduction in the cylinder injection volume; and a switching controller to switch between the first control with the first controller and the second control with the second controller depending on the load.
