product presentation:

The basic structure of diesel engine it is composed of cylinder, piston, cylinder head, intake valve, exhaust valve, piston pin, connecting rod, crankshaft, bearing and flywheel and other components. The diesel engine of the diesel generator is generally a single cylinder or multi-cylinder four-stroke diesel engine. Now I will only talk about the basic principle of the single cylinder four-stroke diesel engine. The diesel engine starts by turning the crankshaft of the diesel engine by hand or other power to make the piston move up and down in the closed cylinder at the top. The piston completes four strokes in the movement: intake stroke, compression stroke, combustion and work expansion stroke and exhaust stroke. When the piston moves from up to down, the intake valve opens and the fresh air filtered by the air filter enters the cylinder to complete the intake stroke. The piston moves from the bottom up and the inlet and exhaust valves are closed. The air is compressed and the temperature and pressure increase to complete the compression process. When the piston is about to reach its peak, the injector sprays the filtered fuel into the combustion chamber in the form of a mist, mixes with high temperature and high pressure air and immediately ignits itself. The high pressure formed pushes the piston down to work and drives the crankshaft to rotate to complete the work stroke. After the work stroke is completed, the piston moves the exhaust valve from the bottom up to open the exhaust to complete the exhaust stroke. The crankshaft rotates half a turn per stroke. After several working cycles the diesel engine gradually accelerates to work under the inertia of the flywheel.

The crankshaft of a diesel engine turns a generator:

Dc generator is mainly composed of generator housing, magnetic pole core, magnetic field coil, armature and carbon brush. Principle of working power generation When the diesel engine drives the armature of the generator to rotate, the armature coil will cut the magnetic force line in the magnetic field because of the remanent magnetic pole iron core of the generator. According to the principle of electromagnetic induction, the magnetic induction generates current and output current through the carbon brush.

Alternator is mainly made of magnetic material made of multiple north and South Pole alternating arrangement of permanent magnets called rotor and silicon cast iron made and wound with a number of series coil armature coil called stator. Principle of working power generation The rotor is driven by the diesel engine to cut the magnetic force line axially. The alternating magnetic poles in the stator form an alternating magnetic field in the coil core. The direction and magnitude of the flux change for many times when the rotor rotates once.

In order to protect the electrical equipment and maintain its normal operation, the current from the generator also needs to be adjusted and controlled by the regulator.
