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, NOx, and smoke), and apart from NOx emissions, a significant improvement has been obtained. There was no increased NOx emission on 15% hydrogen working condition; however, on 45% hydrogen working condition, a dramatic increase arose.

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%.

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.

Dunia otomotif berkembang sangat cepat, contohnya pada sistem pengapian kendaraan, mulai dari penggunaan platina, Capacitive Discharge Ignition (CDI), dan sekarang Electronic Control Unit (ECU) yang memerlukan sistem kelistrikan. Sumber listrik utama pada kendaraan adalah baterai yang menyuplai arus searah. Hasil putaran mesin di ubah oleh dinamo isi menjadi energi listrik, salah satu fungsinya untuk mengaktifkan material pada komponen baterai yang tidak bisa terus menerus aktif menyuplai daya listrik. Maka dari itu perawatan  pada aki harus dilakukan secara berkala, mulai dari mengecek kondisi baterai sampai mengganti dengan baterai yang baru. Pada saat pergantian baterai, terminal baterai dilepas dan dipasang kembali. Dalam hal ini, terdeteksi terjadinya kesalahan pada saat pemasangan terminal baterai, baik karena kelalaian, terburu-buru dan hal lain yang memacu serta produksi kendaraan hanya memberikan indikasi kutub baterai dengan tanda dan warna,  yang tidak bisa menjamin hal tersebut.  Dampak yang ditimbulkan adalah kendaraan tidak dapat dihidupkan. Current Protector adalah sebuah alat yang dapat mendeteksi, mengamankan dan memberitahukan apabila terjadi kesalahan pada saat pemasangan terminal baterai. Alat ini tersusun oleh komponen-komponen elektronik dioda, relay, resistor, light emitting diode (LED), Buzzer  dan sekering. Sehingga, meskipun pemasangan terminal aki tertukar, kendaraan masih dapat dihidupkan.
