ENGINE CONTROLLING APPARATUS

摘要

The engine controlling apparatus includes a selector, a setter, and a controller. The selector selects one of a plurality of injection modes according to the operating condition of an engine, where injection rates of a plurality of injectors or the number of injections performed in one stroke of the engine differs among the injection modes. The setter sets a mode correction amount that reflects an output characteristic of a first sensor corresponding to the injection mode. The controller performs feedback control using both a detection signal from the first sensor and the mode correction amount.

1. An engine controlling apparatus configured to perform feedback control of a fuel injection amount according to a detection signal from a first sensor that detects an actual air-fuel ratio, the engine controlling apparatus comprising:
a selector configured to select one of a plurality of injection modes according to an operating condition of an engine, injection rates of a plurality of injectors or the number of injections performed in one stroke of the engine being different among the injection modes; a setter configured to set a mode correction amount that reflects output characteristic of the first sensor corresponding to the injection mode, and a controller configured to perform the feedback control using both the detection signal and the mode correction amount.
