The diesel generator set is formed by the combination of internal combustion engine and the synchronous generator. The internal combustion engine to allow the maximum power used by the limitations of the parts of the mechanical and thermal loads, therefore, to be required to allow continuous operation of the maximum power, known as the rated power.
The internal combustion engine can not exceed the rated power, otherwise it will shorten its life, and may even cause an accident.

Rated power of diesel engine
National standards, the internal combustion engine on the nameplate rated power is divided into the following four categories:
 (1) 15 minutes of power. That the internal combustion engine to allow continuous operation of the maximum effective power of 15 minutes. Is a short period of time may be overloaded and requires a rated power of acceleration performance, such as cars, motorcycles and other internal combustion engine rated power.
 (2) 1 hour power. That the internal combustion engine to allow continuous operation of the maximum effective power of one hour. Such as wheeled tractors, locomotives, ships and other internal combustion engine rated power.
 (3) 12 hours power. Internal combustion engine to allow continuous operation 12 hours, the maximum effective power. Such as power plant units, engineering machinery with internal combustion engine rated power.
 (4) continuous power. That the internal combustion engine to allow the maximum effective power for a long time continuous operation.
For a unit, the diesel engine output power is the mechanical power of the crankshaft output. According to regulations, power stations, the power of the diesel engine calibration for 12 hours power. Diesel engine at atmospheric pressure for 101.325kPa, the ambient temperature is 20 ℃, relative humidity of 50% standard conditions, the diesel engine rated speed of 12 consecutive hours of normal operation, to achieve effective power Ne said.
General imports of diesel engines, power points mainly with power and standby power, both power ratio of 0.91:1, equivalent to 12 hours power in China and one hour of power points.

The diesel engine is a type of internal combustion engines, is one of the widely used engine. It is the diesel injection combustion heat energy into mechanical energy, heat engines and air mixture into the cylinder. Currently, the captive power plant of communications and other sectors of the national economy mainly depended on it for power driven by a synchronous AC generator. When the power cut, relying on the generating units to provide AC power to ensure that communications equipment or other electrical electricity.
