​How does the generator engine works?

The generator engine is composed of cylinders, pistons, cylinder heads, intake valves, exhaust valves, piston pins, connecting rods, crankshafts, bearings, and flywheels. The generator engine is started by rotating the crankshaft of the diesel engine with manpower or other power to make the piston reciprocate up and down in the cylinder with the top closed. The working principle of the generator engine is as follows.

Principle of movement

The piston completes four strokes in motion: intake stroke, compression stroke, combustion and power (expansion) stroke, and exhaust stroke.

When the generator engine piston moves from top to bottom, 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 bottom to top, the intake and exhaust valves are closed, the air is compressed, the temperature and pressure are increased, and the compression process is completed. When the piston is about to reach its apex, the fuel injector sprays the filtered fuel into the combustion chamber as a mist and mixes it with the high-temperature and high-pressure air. The resulting high pressure pushes the piston down to work and pushes the crankshaft to rotate to complete the work. Work stroke.

After the power stroke of the generator engine is completed, the piston moves from bottom to top, the exhaust valve opens to exhaust, and the exhaust stroke is completed. The crankshaft rotates half a turn per stroke. After several working cycles, the generator engine gradually accelerates into work under the inertia of the flywheel.

Principle of power generation

The rotation of the generator engine crankshaft drives the generator to rotate and generate electricity. The generator engine includes a DC generator and an AC generator. The DC generator is mainly composed of a generator shell, a magnetic pole core, a magnetic field coil, an armature, and carbon brushes. Working principle of power generation: When the generator engine drives the generator armature to rotate because the magnetic pole core of the generator engine has residual magnetism, the armature coil cuts the magnetic lines of force in the magnetic field. According to the principle of electromagnetic induction, the current is generated by magnetic induction and passed through the carbon. Brush output current.

The alternator is mainly composed of several permanent magnets (called a rotor) with alternating north and south poles made of magnetic materials and an armature coil (called a stator) made of silicon cast iron and wound with multiple sets of serial coils. Working principle of power generation: The rotor is driven by the generator engine to axially cut the magnetic lines of force. The alternating magnetic poles in the stator form an alternating magnetic field in the coil core. The rotor rotates once, and the direction and size of the magnetic flux are changed many times due to the change of the magnetic field. Function, the induced current with varying size and direction will be generated in the coil, and the current will be delivered by the stator coil. To protect the electrical equipment and maintain its normal operation, the current generated by the generator also needs a regulator for adjustment control and so on.
