“…Some researchers' studies about developing ECU for dual-fuel engines are given here. Gettel et al 34 built a dual-fuel diesel-natural gas control system for heavy trucks. Zhang et al 35 developed an ECU for dual-fuel diesel-CNG engine using an MC68HC811A1 microcontroller, and Oliveira et al 36 developed an ECU for hydrogen injection in a diesel power generator.…”

In this study, it was aimed to operate today's compression ignition engines easily in dual-fuel mode with a developed electronic control unit. Especially, diesel engines with mechanical fuel system can be easily converted to common-rail fuel system with a developed electronic control unit. Also, with this developed electronic control unit, old technology compression ignition engines can be turned into dual-fuel mode easily. Thus, thanks to the flexibility of engine maps to be loaded into the electronic control unit, diesel engines can conveniently be operated with alternative gas fuels and diesel dual fuel. In particular, hydrogen, an alternative, environmentally friendly, and clean gas fuel, can easily be used with diesel engines by pilot spraying. Software and hardware development of electronic control unit are made, in order to operate a diesel engine with diesel + hydrogen dual fuel. Finally, developed electronic control unit was reviewed on 1500 r/min stable engine speed on different hydrogen energy rates (0%, 15%, 30%, and 45% hydrogen) according to thermic efficiency and emissions (CO, total unburned hydrocarbons, NO x , and smoke), and apart from NO x emissions, a significant improvement has been obtained. There was no increased NO x emission on 15% hydrogen working condition; however, on 45% hydrogen working condition, a dramatic increase arose.
