Fuel injection controller and diagnosis method of fuel supply system |
摘要 |
A fuel injection controller (incorporated in an engine control ECU (50)) for controlling an injection operation of an injector (19) has a program (S32, S33) for executing injections in plural injection patterns including an injection pattern of a multiple injection in a certain order into a certain cylinder of the engine (10) during non-injection operation and a program (S34) for obtaining sums of fluctuation degrees of an engine operating condition due to all the injections in a first injection unit composed of one (single stage injection) of the plural patterns and all the injections in a second injection unit composed of a different one (multiple injection of two stages) of the plural patterns, which are executed by the former program (S32, S33), with an injection condition (cylinder number and data number N). |
