Patent ID: 7748363

Claim:
A multi-cylinder internal combustion engine comprising: an air delivery pipe adapted to convey air to each engine cylinder, at least one intake valve for each cylinder that controls the communication between said pipe and the combustion chamber of the respective cylinder, wherein each intake valve is controlled by actuator means for feeding a determined quantity of air into said combustion chamber, said actuator means being adapted to control the respective intake valve independently from the other cylinders and according to variable actuation modes, injector means for each cylinder adapted to carry out the injection of a determined quantity of fuel into said combustion chamber, electronic control means of the operating conditions of the cylinders adapted to control: said actuator means, for adjusting the opening time and stroke of the respective intake valve, said injector means, for adjusting said determined quantity of fuel, wherein, when the engine is subject to an operating variation request from a first operating condition to a second operating condition, said electronic control means are adapted to select the cylinder to which said second operating condition is to be assigned based on a programming delay, wherein said electronic control means are arranged in order to assign a programming delay as a function of the engine speed only so that in correspondence with an engine speed, the programming delay is associated that is the same regardless of fuel and air quantities and of injection and air-intake timings of the second condition.
