A system and a method is disclosed for universal operation of an internal-combustion engine (), comprising at least an actuator connected to a working device of the engine, an electronic card () including a recording medium for a programmable logic FPGA component and a card synchronization component () for synchronizing the card according to the engine cycle. The method, generates, in the component, an angular reference point in the engine cycle for each cylinder; generates, through the component, actuator control pulses, the pulses being parameterizable in phase and in duration, independent and linked with a single cylinder, performing multiplexing of the pulses to distribute the pulses over at least one of the physical outputs of the card specific to the cylinder considered; and controlling at least one of the actuators linked with one of the physical outputs of the card specific to the cylinder considered, with at least one of the control pulses.

Method and system for multi-purposely controlling an internal-combustion engine on an engine bench testing unit

The present invention relates to a system and a method for continuous operation of an internal-combustion engine (), comprising at least an actuator connected to a working device of the engine, an electronic circuit board or card () comprising a programmable logic FPGA component, means () for synchronizing the card according to the engine cycle, and a central processing unit (CPU). The invention comprises: generating, through the component, a plurality of actuator control pulses, the pulses being parameterizable in phase and in duration, being independent, linked with a single cylinder and synchronized by an angular reference point in the engine cycle for each cylinder; determining pulse parameters and assigning these parameters to the pulses by means of a computing program included in the CPU of the microcomputer at each physical output; and controlling at least one of the actuators by a logic output signal of the circuit board corresponding to at least one of the control pulses.
