Fuel-injection control apparatus for internal combustion engine i.e. compression auto-ignition type diesel engine, has parameter setting part setting control parameter for injection timing control part

摘要

The apparatus has a combustion time detection part i.e. electronic control unit, detecting combustion time in a cylinder, and an injection-timing control part controlling injection timing of a fuel injection valve so that the combustion time is turned into target combustion time. A parameter setting part sets a control parameter for the injection timing control part. An injector drive circuit supplies drive current to the injector. The electronic control unit calculates the target combustion time based on an engine speed and a throttle opening.
