Embodiment Construction

[0096] In the following description, reference is made to the accompanying drawings, which show by way of illustration how the invention may be practiced.

[0097] figure 1 A flowchart 100 shows a method for controlling the execution of operational activities of movable components during each combustion cycle of each cylinder of a multi-cylinder internal combustion engine, according to an embodiment of the present invention. In a first step 101, a first instantaneous value of a control parameter at a first discrete instant is acquired by a first sensor unit. Next, in a second step 102, a first data packet is generated, the first data packet includes data representing the collected first value of the control parameter and the value of the internal clock of the first sensor unit at a first discrete time instant, obtaining The first point in time / parameter space. Then in step 103 the first data packet is transmitted via the communication network to the first control unit, wher...

Abstract

A method and system are disclosed for controlling the execution of operational activities of movable components during each or some combustion cycles of each cylinder of a multi-cylinder internal combustion engine. The method comprises the steps of acquiring, by a sensor unit, a first instantaneous value of a control parameter at a first discrete instant in time, generating first data comprising data representative of the acquired first instantaneous value and a value of an internal clock of the sensor unit A first data packet is transmitted via the communication network to a control unit having an internal clock synchronized with an internal clock of the sensor unit, and the execution of the operational activity is controlled using the control unit. The control unit controls the performance of the operational activity by extrapolating at least part of the data obtained from the first data packet. Thus, a simple and robust method of controlling operational activities is provided.

Description

technical field [0001] The present invention relates to a method and method for controlling the execution of operational activities of movable members during each or some combustion cycles of each cylinder of a multi-cylinder internal combustion engine in response to control parameters that vary over time during each revolution of the multi-cylinder internal combustion engine / or system. Background technique [0002] The precise timing and control of the execution of the operational activities of the movable members during each combustion cycle of each cylinder in a multi-cylinder internal combustion engine is very critical and relies on the updated sum of the instantaneous angular position of the crankshaft which is directly linked to the position of the piston. precise information. The operating activities to be controlled over time in each combustion cycle include, for example, the timing of fuel injection, ignition and actuation of intake and exhaust valves and the supp...
