Embodiment Construction

[0034] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, the same components have the same reference numerals, and also have the same names and functions. Therefore, its detailed description will not be repeated.

[0035] 1 is a schematic configuration diagram of an engine system controlled by an engine ECU (Electronic Control Unit), which is a control device for an internal combustion engine according to an embodiment of the present invention. In FIG. 1 , an in-line four-cylinder gasoline engine is shown, but the application of the present invention is not limited to such an engine.

[0036] As shown in FIG. 1 , engine 10 includes four cylinders 112 each connected to a common surge tank 30 via a respective intake manifold 20 . The surge tank 30 is connected to an air cleaner 50 via an intake pipe 40 . An air flow meter 42 is arranged in the intake pipe 40 , and a throttle valve 70 ...

Abstract

An engine ECU executes a program comprising the steps of: calculating a post-warm-up steady-state port wall deposit quantity (a); calculating a shared-injection steady-state port wall deposit quantity (b) based on port wall deposit quantity (a); calculating a difference (c) in one cycle of shared-injection steady-state port wall deposit quantity (b); making a correction considering an engine temperature and an engine speed to calculate a transition correction quantity (d); and converting transition correction quantity (d) into a wave form representing temporal transition to make a wall deposit correction with higher priority on a port injection quantity.

Description

technical field [0001] The present invention relates to a control apparatus for an internal combustion engine having a first fuel injection mechanism (in-cylinder injector) for injecting fuel into a cylinder and a second fuel injection mechanism (in-cylinder injector) for injecting fuel into an intake manifold or intake port. Two fuel injection mechanisms (intake manifold injectors), and especially those that are attached to the inner wall of the intake port when the fuel injection ratio between the first and second fuel injection mechanisms changes or when the required load of the internal combustion engine changes technology of fuel volume. Background technique [0002] An internal combustion engine is known having an intake manifold injector for injecting fuel into an engine intake manifold and an in-cylinder injector for injecting fuel into a combustion chamber of the engine, and is configured to judge The fuel injection ratio between the intake manifold injector and th...
