The basic structure of a diesel generator consists of a diesel engine and a generator, with the diesel engine providing power to drive the generator.

The basic structure of a diesel engine consists of components such as cylinders, pistons, cylinder heads, intake valves, exhaust valves, piston rods, connecting rods, crankshafts, bearings, and flywheels.

The diesel engine of a diesel generator is typically a single-cylinder or multi-cylinder four-stroke diesel engine. I will only explain the basic working principle of a single-cylinder four-stroke diesel engine: The diesel engine starts by manually or with other power sources rotating the engine's crankshaft, causing the piston to move up and down within the sealed cylinder at the top.

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

When the piston moves from top to bottom, the intake valve opens, and fresh air filtered by the air filter enters the cylinder to complete the intake stroke. As the piston moves from bottom to top, both the intake and exhaust valves are closed, compressing the air, which increases the temperature and pressure, completing the compression process.

As the piston approaches the top dead center, the fuel injector sprays filtered fuel into the combustion chamber in a mist, where it immediately mixes with the hot, high-pressure air and ignites on its own, burning. The resulting high pressure pushes the piston down to perform work, rotating the crankshaft and completing the power stroke.

After the power stroke is completed, the piston moves from bottom to top, the exhaust valve opens to expel exhaust, and the exhaust stroke is completed. Each stroke rotates the crankshaft by a half turn.

After several work cycles, the diesel engine gradually accelerates into operation under the inertia of the flywheel.

The diesel engine crankshaft rotates to drive the generator, which can be either a DC generator or an AC generator.

Direct current generators are primarily composed of the generator housing, magnetic pole core, field coil, armature, and carbon brushes. Working principle of power generation: As the diesel engine drives the armature of the generator to rotate, due to the presence of residual magnetism in the magnetic pole core of the generator, the armature winding cuts through the magnetic lines of force in the magnetic field. According to the principle of electromagnetic induction, current is generated by magnetic induction and output through the carbon brushes.

The alternator is mainly composed of multiple permanent magnets (referred to as the rotor) made of magnetic materials, arranged alternately with north and south poles, and a stator winding (referred to as the stator) made of silicon cast iron and wound with multiple sets of series-connected coils.

Operation Principle: The rotor is driven by the diesel engine to cut the magnetic lines axially, and the alternating arrangement of poles in the stator forms an alternating magnetic field in the coil core. As the rotor rotates one revolution, the direction and magnitude of the magnetic flux change multiple times. Due to the transformation effect of the magnetic field, alternating current of varying magnitude and direction is generated in the coil, which is then transmitted out by the stator winding.

To protect electrical equipment and maintain normal operation, the current generated by the generator requires regulation and control by regulators, etc.
