In the cylinder of the diesel generator set, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel sprayed from the fuel injector. Under the upward extrusion of the piston of the diesel generator set, the volume is reduced and the temperature rises rapidly. The ignition point of diesel. The diesel is ignited, the mixed gas burns violently, and its volume expands rapidly, pushing the piston down, which is called ‘work’. The cylinders of the diesel generator set work sequentially in a certain order, and the thrust acting on the piston is transformed into the force that pushes the crankshaft to rotate through the connecting rod, thereby driving the crankshaft to rotate. In this way, the diesel generator completes a working cycle.
With the repetition of one work cycle after another, the diesel generator set runs continuously. The core of diesel engine control 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 governor adopts double closed-loop control, uses a speed sensor to detect the speed of the diesel engine, converts the detection result into a proportional electrical signal, compares it with a given standard speed signal, and obtains a deviation signal, and then compares it with the actuator of the diesel generator set. The position feedback signals are added together, and the synthesized signal is used as the input signal of the actuator action, and the fuel supply is adjusted by controlling the position of the fuel injection pump rack of the diesel generator set, so as to achieve the purpose of speed regulation and speed stabilization. At present, foreign diesel engines also use advanced engine “electronic injection” control technology, which has excellent performance in terms of load characteristics, fuel saving, environmental protection emissions, and noise reduction. The active power adjustment of the generator set is the adjustment of the speed of the diesel generator.
