Abstract

A control device (1) of an electronically controlled internal combustion petrol engine (2) converted to be selectively driven by fuel gas or petroleum completely includes the original control device (1) of the engine, wherein all original sensors (4) connected to the original control device (3) also remain unchanged; its digital map wherein the original control unit (3), when gas is used as fuel, still controls ignition and generates a signal for the beginning and duration of opening of a nozzle (6) for gas injection, wherein the signal is transferred along a conduct (8) into the supplemental control unit (5), in which it is processed in the same microprocessor step of the control device (3) by a corrected correction constant (the corrected part being dependent on the use of fuel gas and its displacement properties), so that the duration of opening of the nozzles (6) for gas supply into the cylinders of the engine (2) is changed, whereas the time of the beginning of opening of the nozzles (6) remains the same as determined by the original control device (3).
