Diesel generator is a small power generation equipment, refers to the diesel and other fuel, diesel engine as the prime power to drive the alternator working. The whole unit is usually composed of diesel engine, alternator £¬control panel£¬fuel tank, starting motor and control battery, protection device, emergency cabinet and other components.
 
The basic structure of diesel generators is composed of diesel engine and alternator £¬diesel engines as prime power to run alternator.
 
The basic structure of the diesel engine: it consists of cylinder, piston, cylinder head, intake valve, exhaust valve, piston pin, connecting rod, crankshaft, bearing and flywheel and other components. Diesel generators are generally single-cylinder or multi-cylinder four-stroke diesel engine, the following I just introduce the single-cylinder four-stroke diesel engine working basic principles: diesel engine is through the human or other power to turn the diesel engine crankshaft so that the piston in the top closed cylinder In the repeating movement.
 
The piston completes four strokes during exercise: intake stroke, compression stroke, combustion and work (expansion) stroke and exhaust stroke. When the piston from the top to down  the valve to open,the fresh air through the air filter will put into the cylinder to complete the intake stroke.
 
The piston from the bottom to up movement, inlet and the exhaust valve are closed, the air is compressed, the temperature and pressure increased to complete the compression process. When the piston is about to reach its peak, the injector injects the filtered fuel into the combustion chamber in a fog and mixes with the high temperature and high pressure air. The high pressure is used to push the piston downwards to push the crankshaft to rotate. Work trip. After the work trip is completed, the piston moves from the bottom to up, the exhaust valve open for exhaust, complete the exhaust stroke.

Each stroke crankshaft rotates half a turn. After several cycles of work, the diesel engine in the flywheel under inertia gradually accelerated into the work.
 
Diesel engine crankshaft rotation will drive the generator rotation power to produce electricity, generators have DC generators and AC generators.
 
The DC generator is mainly composed of generator shell, pole iron core, magnetic field coil, armature and carbon brush. Working principle: When the diesel engine to drive the alternator armature rotation, due to the magnetic pole of the generator there is remanence, so the armature coil magnetic field in the magnetic line, according to the principle of electromagnetic induction, by the magnetic induction current and the brush output current!
 
The AC generator is mainly composed of a number of permanent magnets (called rotors) arranged alternately in the north and south poles by magnetic materials and armature coils (called stators) made of silicon cast iron and having multiple sets of series coils. The principle of working power generation: the rotor is driven by the diesel engine to cut the magnetic field lines. The alternately arranged magnetic poles in the stator form alternating magnetic field in the coil core, the rotor rotates one turn, the direction and size of the magnetic flux changes many times. Due to the transformation of the magnetic field, In the coil will produce the size and direction of the induced current and the stator coil to send out the current.
 
In order to protect the electrical equipment and maintain the normal work,current produced by generator also need to adjust and control  by the regulator.
