FUEL INJECTION CONTROL DEVICE AND FUEL INJECTION CONTROL METHOD

摘要

This fuel injection control device controls a direct-into-cylinder fuel injection type spark ignition engine provided with a fuel injection valve through which fuel is injected directly into a cylinder, and an ignition plug which effects spark ignition of an air-fuel mixture in the cylinder. If the site on which the injected fuel impinges is in a certain low-temperature condition, the fuel injection control device injects the fuel by changing the fuel injection conditions under certain operating conditions in such a way as to limit continued impingement of the fuel spray mist in the same location.
