Systems and methods for controlling fuel that is supplied to cylinders of an internal combustion engine are described. In one example, the fuel is controlled in response to output of two different outer-loop fuel controllers. The fuel may be controlled acc...

The present invention relates to a method for determining an injection pressure (p_erm) for injecting fuel through an injection valve (4a-d) into a cylinder (3a-d) of an internal combustion engine (2), wherein the injection pressure of the fuel is generate...

Upon no detection of the closing abnormality where the EGR valve does not become in the totally closed state (when the flag Fa is value '0'), the engine is controlled using the target fuel injection amount Qf* obtained from the correction of the basic fuel...

The start and/or end of fuel injection are detected from the pressure variation in the common-rail system. The start is registered from a pressure drop, the end from a rise. The variation is compared with thresholds. Values are compared with expectations, ...

The method involves determining the fuel quantity to be dispensed depending on a load parameter and a parameter describing the form of the fuel jet and/or the fuel atomization of the injection valve. A base value (MFFBAS) for fuel quantity is determined fr...

The method involves defining a control duration (110) for a quantity determining control element starting with a fuel quantity. The control duration is corrected depending on a parameter that characterizes the pressure in a control chamber. A time paramete...
