Gasoline Generator Everyday Life Has A Wide Range Of Uses
May 31, 2017

Gasoline generator is a power generation equipment, refers to the gasoline and other fuel, is the other forms of energy into electrical energy machinery and equipment,

It is driven by turbines, turbines, diesel engines or other power machinery to convert the energy generated by the flow of water, air, fuel, or nuclear fission into mechanical energy to the generator and then from the generator to electrical energy. Generators are widely used in industrial and agricultural production, defense, technology and daily life.

basic structure

The generator is usually composed of parts such as stator, rotor, end cap and bearing. The stator consists of a stator core, a wire wrap, a base, and other structural parts that secure these parts.

The rotor consists of rotor core (or magnetic pole, magnetic choke) winding, retaining ring, center ring, slip ring, fan and shaft and other components. By the bearing and the end of the generator stator and rotor connection assembled, so that the rotor can rotate in the stator to do the movement of magnetic lines, resulting in induced potential, through the terminal leads, connected to the circuit, it produced a current.

working principle

The engine is the chemical energy into mechanical energy of the machine, its transformation process is actually the process of working cycle, simply is through the combustion of fuel in the cylinder, generate kinetic energy, driving the engine cylinder piston reciprocating movement, thus The connecting rod connected to the piston and the crank connected to the connecting rod, around the crankshaft center for reciprocating circular motion, and the output power.

We analyze this process: a work cycle includes four piston strokes (the so-called piston stroke refers to the piston from the top dead center to the distance between the bottom point of the process): intake stroke, compression stroke, expansion stroke Travel) and exhaust stroke.

Intake stroke

In this process, the engine's intake valve opens and the exhaust valve closes. As the piston moves from the top dead center to the bottom dead center, the cylinder volume above the piston increases, so that the pressure in the cylinder will be below atmospheric pressure, that is, vacuum suction in the cylinder, so that the air passes through the intake duct and The valve is sucked into the cylinder, while the nozzle spray atomized gasoline and air mixed well.

At the end of the air intake, the gas pressure in the cylinder is about 0.075-0.09 MPa. While the temperature of the combustible mixture in the cylinder has risen to 370-400K.
