    3) Volvo generator set power generation principle
    Diesel engine driven generators operate, diesel energy into electricity. Diesel engine cylinder, through the clean air after the filtering of the air cleaner with the fuel injector ejecting a high-pressure atomizing diesel sufficiently mixed in the extrusion of the piston upward, the volume is reduced, the temperature increased rapidly to reach the ignition of diesel fuel. Diesel ignited intense burning of the gas mixture, the volume of the rapid expansion of downstream push the piston, known as 'do work'. Each cylinder certain order of work is, the thrust after acting on the piston rod has become the driving force of crankshaft rotation, so as to drive the crankshaft rotation. Brushless synchronous AC generator with diesel engine crankshaft coaxial installation, you can take advantage of the rotation of the diesel engine driven generator rotor, 'electromagnetic induction' principle, the generator will output the induced electromotive force will be able to generate the current through the load circuit closed .
Volvo Genset parameters
(1) Rated Power (pe): maximum active power, diesel generator sets in the nominal operation can be output in kilowatts (kW) or megawatts (MW).
(2) Rated power factor (cosφ): refers to the running of the motor rated power factor.
(3) Rated voltage (Ue): diesel generator sets in the normal operation of the line voltage in volts (V) or kilovolt (kW).
(4) Rated Current (Ie): diesel generator set running at rated line current, Ann (A) or thousands Ann (kA).
(5) Rated speed (nc): diesel generator set to 50Hz need speed in order to maintain the frequency of the alternating current units of rev / min (r / min).
(6) Rated efficiency (ηe): refers to the efficiency of diesel generator sets rated state run.
(7) Rated frequency (fe): China provides a nominal frequency of 50 Hz.
(8) the rated temperature rise: run the stator and rotor windings of the diesel generator sets to allow of degrees higher than the ambient temperature. Our provisions ambient temperature of 40 ℃.
4. The Korean Daewoo Hyunju generator
    Daewoo Heavy Machinery was established in 1973, initially called the Korean Kikai Seisakusho, after the development of the machinery industry in Korea has been led by leading enterprises, has now become the largest machinery company in Korea.
