An object is to provide a method and a system of controlling a load during misfire of an engine, whereby additional stress on a crank shaft is calculated from torsional vibration of the crank shaft to obtain an output limit rate, and an operation output of...

Method for estimating the vehicle fuel consumption, comprising the following subsequent steps: (i) attribution of a first score to at least a first operating parameter (S, RPM, T, D) of the vehicle and/or of a respective internal combustion engine, (ii) at...

The invention relates to a method for operating an internal combustion engine (10), in which fuel is introduced into a combustion chamber (14) of the engine (10) in one primary injection (HE) and at least one secondary injection (NE), characterized in that...

A method and a system for determining the state of a vehicle equipped with a thermal engine and for controlling actuation of an on-board electronic device are described. An inertial sensor is arranged for detecting a variable representative of the vibratio...

A learning method for an internal combustion engine (10) may include steps as follows. Injection for learning is executed from an injector (43A to 43D) during non-injection operation of the engine (10) with a timing. A correction amount for the injector (4...

The present invention relates to an apparatus for controlling a drive force generated by a drive source of a riding type vehicle, comprising means for detecting an abnormality of the drive force control apparatus configured to detect the abnormality of the...

A method for estimating a combustion torque acting upon a crankshaft of an internal combustion engine comprises acquiring an instantaneous engine speed signal, calculating a cyclic engine speed signal based on the instantaneous engine speed signal, averagi...

The process involves determining a value of an induced operation criterion (C) of an internal combustion engine, distinct from an engine speed criterion (N) and from an air flow criterion (Q). The induced criterion (C) is compared with a threshold conditio...
