In apparatuses and methods for controlling a fuel injector (22), a fuel shot is injected during a zero fuel condition. A rail pressure drop corresponding to the fuel shot is determined. A change in engine speed corresponding to the fuel shot is determined....

The unit (6) calculates a difference between an engine rotation speed variation when a learning injection is performed and an engine rotation speed variation when the learning injection is not performed, as rotation speed increases. The unit calculates an ...

There is provided a control system for an internal combustion engine, which is capable of matching an output torque of the engine with a demanded torque excellently when the combustion mode is switched, thereby enhancing drivability. A demanded fuel amount...

An electronic control unit (90) for managing and controlling an operational state of a diesel engine (1) first opens a throttle valve (32) completely during the implementation of fuel cut so as to replace gas remaining in an exhaust system (40) with fresh ...

The engine has a pressure accumulator (17), in which the pressure is limited to a nominal value relative to an offset value. During overrun operation, no fuel is injected by a valve (21), and the offset value is reduced to a minimum or even to zero. Overru...

A control apparatus of an internal combustion engine for performing fuel cut control for suspending fuel supply to the internal combustion engine during the operation, comprising at least any one of means for controlling immediately before the fuel cut con...

An engine can switch a combustion mode between homogeneous charge combustion and stratified charge combustion. The engine is controlled in accordance with a load acting on the engine. When homogeneous charge combustion is executed, an intake pressure, or a...
