Abstract：To solve the problem of low fuel substitution rate and poor emission for diesel with mechanical pump, Z6180/S dual fuel engine by dual electronic control unit (ECU)control is developed,the diesel and natural gas injection are controlled by separate ECU.The results of engine bench and 2500 h emission durability test show that dual ECU control technology can realize accurate fuel injection and combustion optimization under all working conditions and different working modes of the engine, the maximum gas substitution rate of Z6180/S engine can reach 90%, the pollutant emission of the engine meets the requirements of national standards.
Keywords:both control of diesel and natural gas; dual fuel engine; ECU control technology;combustion optimization
