Product Description
Diesel and Natural Gas Dual-Fuel System Conversion KitDual-fuel engine control system is mainly composed of gas electronic control unit, gas injection valve, wiring harness, sensors, monitoring instrument, etc. It can realize engine gas control,parameter detection alarm, fault alarm and other functions.Brief Description of Control ModeThe engine starts in pure diesel mode and remains in diesel mode when entering idle speed. When the gas mode is ready, switch into dual-fuel mode through the mode switch button of the monitor. In order to prevent the speed fluctuation in the switching process, the switching of gas inlet and oil retreat is flexible. At a certain interval (calibration), the gas increases the step size step (calibration). When the dual-fuel mode is switched to diesel mode, the cylinder circulating gas volume decreases slowly to zero according to a certain slope (calibration). Electric control system power supplyElectric control system adopts dual power supply, one is 220VAC main power supply, the other is 24VDC backup power supply, dual fuel electric control system can enter normal working mode after any power supply is connected. Gas Electric Control UnitDual-fuel engine management core, through each sensor to collect engine pressurization pressure, speed, gas pressure and other operating conditions information, output execution signals such as gas injection volume, gas injection timing, through CAN bus communication with the monitoring instrument. The ECU functions are described as follows: It has the ability to control multi-point sequential injection of gas;Crankshaft 60-2 (magneto-electric, default number of teeth 60-2, needs to be confirmed on site), camshaft 16+1 (Hall, default number of teeth 16+1 needs to be confirmed on site) gear disc signal collection; With CAN bus, in line with J1939 protocol, with reserved calibration interface;With eight-way electromagnetic gas jet valve driver ports, and the two ECUs have 16-way jet valve driver ports;With fault diagnosis and self-protection functions.MonitorOn the front panel of the monitoring instrument, there are power indicator, working mode indicator (dual fuel mode or pure diesel mode), setting running, shutdown, emergency shutdown, remote control fuel leakage and alarm status indicators. When the alarm light is on, the display window of the corresponding over-limit parameter flashes. Mode conversion button, overcontrol button, and muffler, reset, self-check and other operating functions; With CAN bus, in line with J1939 protocol, and remote monitoring instrument and ECU through CAN communication, CAN realize the sensor, ECU and actuator and other components of the fault alarm function, and fault can be consulted. Display engine speed, exhaust temperature of 16 cylinders, oil pressure, supercharger pressure temperature, pressurized air pressure temperature, gas pressure, gas temperature, power supply voltage and other parameters collected by the system.With engine parameters alarm, fault alarm and other functions.Monitor displayed unit: Pressure, two decimal points, MPa; Temperature: ºCThe monitoring instrument has the function of data recording and storage, which records the operation data of dual fuel engine at a certain frequency and can be read by the specified equipment.Record historical data, the specific content of recorded data includes the data collected and measured by ECU and monitoring instrument; Fault alarm record, when the engine parameter exceeds the preset value (preset value is adjustable), it will output alarm signal or stop signal, and record the alarm at the same time. The installation position of the remote communication module is reserved in the monitoring instrument (guideway installation, module size 130mm*96mm*36mm, power supply DC24V), and the power supply and communication line are arranged for the module.Protection level: IP54; The remote monitoring instrument can be installed on the bridge control console and assigned operator can monitor the parameters and switch the dual fuel mode. Gas Injection Valve D20H50Time to fully open: 1.5 ms, fully close 1.5ms;Driving voltage: 24VDCMax. Current for pull up: 28AMaintained Current: 6+0.5AThe gas injection valve is a precision component. Before the gas enters the gas rail, install a precision filter. The filter precision of the gas is required to be 1μm.Gas common rail pipe and partsThe gas common rail tube is the pressure storage chamber of natural gas, which ensures that the gas pressure emitted by the gas injection valve is within a constant range during the engine operation, and ensures the accurate injection amount of natural gas. Special rail tube for double wall structure, the scope of supply see the gas common rail parts list. Gas Common Rail Pipe and Parts | Description | Drawing No. | Qty | Rmk |
