Kraftstoffeinspritzsteuerungsvorrichtung für eine Brennkraftmaschine

摘要

An internal combustion engine (10) is provided with a port injector (28) and an in-cylinder injector (22). Before a port injection is started, the total amount of fuel to be injected is calculated (at an injection amount calculation timing). The port injection fuel amount and the in-cylinder injection fuel amount are calculated by appropriately dividing the total amount between them. If a change of the operating load on the internal combustion engine (10) is detected after the injection amount calculation timing, the load change is reflected in the amount of fuel to be injected in the current engine cycle by increasing or decreasing the in-cylinder injection fuel amount.
