Abstract Nowadays global engine construction gets significant progress at a technological level, but specified manufacturers do not release any information about the composition, the structure of the algorithms and the software used by their equipment. It is possible to obtain information only fragmentary and, for example, the description of the electronic control unit algorithm is completely missing. This is a barrier for small companies to improve and adjust existing engines for specific purposes. The present paper describes and develops algorithm synthesis for an electronic diesel engine regulator. Mathe-matical modelling of the automatic control system has been carried out within the framework of the research. The results of the research have demonstrated the efficiency and sustainability of automatic electronic control system using the proposed algorithm.

To meet the actual application requirements for the diesel–natural gas dual-fuel engine refit, a new electronic control system for the dual-fuel engine is developed in the study. Specifically, an active mode switching board is developed to achieve flexible switching between the pure diesel mode and dual-fuel mode. A diesel nozzle physical simulator is developed to ensure that the original diesel electronic control unit does not trigger fault alarm when engine works in the dual-fuel mode. Moreover, a dual-fuel electronic control unit, which uses the high-speed and multicore TMS320F28M35 as its microcontroller unit, is additionally developed on the basis of the original diesel electronic control unit. The peak and hold current shape for the diesel nozzle is intelligently controlled by the software program in C2000 core. Experiments reveal that the developed electronic control system can select a proper working mode according to the engine operation condition and smoothly switch the working mode without any fault alarms.

Operation Cost

In order to convert the high pressure common rail system engine to CNG/Diesel dual fuel engine, an electronically controlled system is developed. The system includes a CNG fuel supply system, the CNG electronic control unit (ECU) and its matching harness etc. During starting and idle load conditions, the engine runs under pure diesel mode, when the speed and load reached a certain set point, the diesel ECU reduces the pilot diesel quantity, meanwhile, the CNG ECU increases the natural gas quantity, then the engine runs under dual fuel mode. The engine experiment data show that in different conditions, the highest substitution rate is 90% and the average substitution rate is 83%; the average savings ratio of operation cost per hour is 26%.
