TAD-300 Starlight Ricardo diesel generator set starting principle explanation

>Starlight Ricardo diesel generator set starting principle description: First turn on the ignition key switch, the DC starter motor runs, and drives the crankshaft coaxial with the flywheel to run, so that when the piston moves from top to bottom, the air enters the cylinder from the intake valve , then the piston moves upward in the reverse direction, and the air in the cylinder is compressed by the piston. Then the diesel is injected into the combustion chamber through the oil inlet pipe and the oil pump injection system, and burns in contact with the compressed high-temperature air. The huge pressure generated by the expansion of the gas pushes the piston toward It moves downward and rotates the crankshaft through the connecting rod to output torque to the outside. Finally, the piston moves upward from bottom to discharge the expanded and burned exhaust gas out of the cylinder. At this point, a working cycle is completed. As the working cycle is repeated one after another, the diesel engine continues to operate. The control core of the diesel engine is to adjust and stabilize the speed by controlling the fuel injection pump, which is generally divided into mechanical speed regulation and electronic speed regulation. The electronic speed regulator adopts double closed-loop control, uses a speed sensor to detect the diesel engine speed, converts the detection result into a proportional electrical signal, compares it with a given standard speed signal, and obtains a deviation signal, which is then combined with the position feedback signal of the actuator After adding, the synthesized signal is used as the input signal for the actuator action, and the fuel supply is adjusted by controlling the gear rod position of the diesel injection pump, thereby achieving the purpose of speed regulation and stability. At present, foreign diesel engines also use advanced engine electronic injection control technology, which has excellent performance in terms of load characteristics, fuel saving and environmental protection emissions, and noise reduction. The active power adjustment of the generator set is the adjustment of the diesel engine speed.
