Control system of dual-fuel engine

A dual-fuel engine control system comprising:

• a sensor for generating sensing information by sensing a parameter related to a dual-fuel engine;
• a main controller for receiving the sensing information from the sensor and generating a control signal for controlling a micro-pilot injection valve and a gas fuel inlet valve by analyzing a state of the dual-fuel engine on a basis of the sensing information;
• an electric fuel injection (EFI) controller for receiving the control signal generated by the main controller and controlling the micro-pilot injection valve and the gas fuel inlet valve on a basis of the control signal;
• and
• a deep learning analyzer for analyzing a state of the dual-fuel engine on the basis of the control signal transferred from the main controller and the sensing information transferred to the main controller at a time point of generating the control signal, and transferring an analysis result to at least one of the main controller and the EFI controller, wherein
• when the analysis result is received from the deep learning analyzer, the EFI controller controls the micro-pilot injection valve and the gas fuel inlet valve before receiving the control signal from the main controller,
• wherein the sensor includes:
• a first sensor for generating first sensing information including at least one of information on temperature of coolant, information on the number of rotations of the engine and information on pressure of a fuel filter;
• and
• a second sensor for generating second sensing information including at least one of information on fuel pressure of a common rail, information on vibration frequency in a cylinder, information on the number of rotations of a motor which drives a diesel fuel pump, a rotation angle of a crankshaft, and a Top Dead Center (TDC) of a first cylinder, and
• wherein the main controller determines generation of knocking on the basis of the sensing information, in which the knocking is determined to be divided into light knocking and heavy knocking, generates the third control signal for controlling open and close of the micro-pilot injection valve and the fourth control signal for controlling open and close of the gas fuel inlet valve if it is determined that the light knocking is generated, and generates the fifth control signal for controlling the micro-pilot injection valve to be closed and the sixth control signal for controlling the gas fuel inlet valve to be closed to shut down the dual-fuel engine if it is determined that the heavy knocking is generated, and the EFI controller receives the third to sixth control signals from the main controller, controls the micro-pilot injection valve according to the transferred third control signal and the fifth control signal, and controls the gas fuel inlet valve according to the fourth control signal and the sixth control signal.
