An internal combustion engine is provided with a fuel injector 13 which injects fuel into an intake port 8 and an exhaust variable valve timing mechanism A which can change a valve timing of an exhaust valve 9. A control device executes early exhaust valve...

An apparatus and method for controlling the intake air amount in an internal combustion engine provided with a throttle valve and an intake air amount changing means linked with the same, the intake air amount control apparatus and method of an internal co...

A system and a method at an internal combustion engine with at least one valve per cylinder is presented. At least one signal (SL1) corresponding to a requested torque is received from a maneuvering device (2). Based on the requested torque, at least one r...

A method is presented in an internal combustion engine, comprising individually controllable valves, the method comprising adjusting a combustion load at a first ignition at least partly on the basis of at least one interval between two ignitions of the en...

A valve timing correction control apparatus for an internal combustion engine (1) is provided. The engine (1) includes a plurality of banks and variable valve operating mechanisms (2) disposed at the respective banks for variably controlling valve timings ...

A system 12 and method for determining a value for a control variable for an engine 10 are provided. The system 12 includes an electronic control unit 56 configured to obtain a plurality of pairs of programmed timing values for the opening and closing, res...

The compression ratio control includes determination, in real time, of the optimal compression ratio ( SIMILAR Topt) for the operation of the engine. The valves are then controlled for admission of gas to the combustion chambers at times appropriate to pro...

A valve timing control apparatus of an internal combustion engine (11) that includes a biasing device (54) that applies bias force to a camshaft (21, 22) of intake or exhaust valves (19, 20) so as to bring the valve timing of the engine into a predetermine...
