A control device of a high-pressure fuel pump of an internal combustion engine capable of improving stability in controlling the drive of the high-pressure fuel pump by limiting the end timing of a drive signal of the high-pressure fuel pump and driving an...

Damping device for suppressing torsional vibrations in the drive branch (3) of an internal combustion engine (1) comprises a detection device for determining a mechanical state variable (delta alpha MODELL, delta alpha IST, alpha 1, alpha 2, alpha '1, alph...

A system 10 and method for monitoring a control system parameter determine a difference between a desired and estimated or measured parameter value, apply a weighting factor to the difference and select a control strategy based on the weighted difference. ...

Operation of an exhaust gas sensor in an internal combustion engine exhaust involves control of the operating parameters of the sensor by use of model-based control and/or of exhaust gas-dependent pre-control. An Independent claim is also included for a de...

The exhaust side control unit (7a) sets the dead-time of the exhaust system (E) successively and variably according to the flow of the exhaust gas fed to the catalytic device (3) and successively identifies the values of the parameters of the exhaust syste...

To provide an algorithm-based optimizing controller which can search for an optimal solution in line with user requirements with reduced time requirements for optimization. An interactive optimizer 310 searches for an optimal solution of a responsivity cal...

In apparatus and method for calculating a mass air quantity sucked into a cylinder of an internal combustion engine, income and outgo calculations between a mass air quantity flowing into an intake manifold and that flowing out from the intake manifold is ...

The air flow into an engine 10 is estimated via a speed-density calculation wherein the volumetric efficiency is estimated on-line. There are three interconnected observers 90,92,94 in the estimation scheme. The first observer 90 estimates the flow through...

The method involves measuring engine combustion air pressure with an induction pipe pressure sensor and passing a sensor signal corresponding to instantaneous pressure to a controller, which derives a control signal the air-fuel mixture fed to the engine. ...
