ABSTRACT
The article presents an issues concerning selection of controlling algorithms for operation of supercharged compression ignition engine fueled additionally with CNG gas, including implemented control procedures, adjustment algorithms and operational algorithms. As the result, the engine which is run in dual fuel system operates under control of two controllers, factory ECU controller, governing fueling with the base fuel (Diesel oil) and all fueling parameters, and the second controller for gaseous fuel supply. Priority of operation of the controllers relates to fueling with Diesel oil, while the gas is treated as supplementary fuel. Due to possibility of usage of factory made original ECU controller as used with Diesel oil supply; it has been presented proposal of its software in form of array algorithms.
