Diesel generator principle

FOR IMMEDIATE RELEASE
(Free-Press-Release.com) January 5, 2012 -- In the diesel engine cylinder, through the air filter of the clean air filter and oil nozzle jet of high pressure atomized diesel are fully mixed, in the piston upward pressure, volume, temperature rises rapidly, reaching diesel ignition. Diesel fuel is ignited, mixed gas burning, the volume of rapid expansion, pushing the piston downward, known as the ' work '. Each cylinder according to a certain sequence of work, acts on the piston thrust through the connecting rod to drive the crankshaft strength, so as to drive the rotation of the crankshaft.

The brushless synchronous AC generator and diesel engine crankshaft mounted coaxially, can use diesel engine rotates to drive the rotor of the generator, using the ' induction ' principle, generator can output induction electromotive force, the closure of the load circuit can produce electricity.
Here only to describe the basic working principle of generating set. To be usable, stable power output, we also need a series of diesel engine and generator control, protection devices and circuits.

Diesel generator is a kind of independent power generation equipment, means the diesel fuel, to diesel engine prime mover driven generator to power machinery. The whole unit is generally composed of diesel, generator, a control box, a fuel tank, starting and control storage battery, protection device, emergency cabinet and other components. Integral can be fixed on the foundation, positioning, can also be installed in the trailer, for mobile use.
Diesel engine combustion diesel to obtain the energy release of the engine. It is by the German inventor Rudolf Diesel ( RudolfDiesel ) invented in 1892, to commemorate the inventor, diesel is to use his surname "Diesel".

The working process of diesel engine and gasoline engine has many of the same place, each working cycle has air intake, compression, power, and exhaust four travel. But as the diesel fuel diesel, its viscosity than gasoline, not easy evaporation, while its autoignition temperature than the gasoline is low, so the combustible mixed gas formation and ignition means are different with gasoline engine. The difference is mainly, diesel engine mixed gas in a cylinder is compression ignition, not lit.
Compared with gasoline engine , diesel engine with good fuel economy, emissions of nitrogen oxides is low, low speed high torque characteristics, because of its excellent environmental characteristic by the European cars and respected, for comfort, noise and other defects, the European advanced automotive industry, has no problem, the current diesel engine properties and working and has not much difference between gasoline engine.

In addition to diesel generators, generator can divided into gasoline generators , welder generator, inverter generator , LPG generators , and so on.
