MTU柴油发动机的结构与原理

 国家标准规定,在内燃机铭牌上的标定功率分为下列四类：

 (1)15分钟功率。即内燃机允许连续运转15分钟的最大有效功率。是短时间内可能超负荷运转和要求具有加速性能的标定功率,如汽车、摩托车等内燃机的标定功率。

 (2)1小时功率。即内燃机允许连续运转1小时的最大有效功率。如轮式拖拉机、机车、船舶等内燃机的标定功率。

 (3)12小时功率。即内燃机允许连续运转12小时的最大有效功率。如电站机组、工程机械用的内燃机标定功率。

 (4)持续功率。即内燃机允许长时间连续运转的最大有效功率。

对于一台机组,柴油机输出的功率是指它的曲轴输出的机械功率。MTU柴油发动机的结构与原理|MTU柴油发动机的结构与原理维修技术|MTU柴油发动机的结构与原理资料|MTU柴油发动机维修服务商根据规定,电站用柴油机的功率标定为12小时功率。即柴油机在大气压力为101．325kPa,环境气温为20℃,相对湿度为50％标准工况下,柴油机以额定转速连续12小时正常运转时,达到的有效功率,用Ne表示。

一般进口柴油机,其功率分为主用功率和备用功率,两者功率之比为0．91：1,相当于我国12小时功率和1小时功率之分。

柴油机是内燃机的一种类型,是现代广泛应用的发动机之一。它是将柴油喷射到汽缸内与空气混合燃烧得到热能转变为机械能的热力发动机。目前,通信和其他国民经济部门的自备电站主要依靠它作动力带动同步交流发电机发电。当市电停电时,依靠该机组发电,提供交流电源,保证通信设备或其他电器的用电。本章就MTU柴油发电机组柴油机的结构和原理分别进行简单的介绍。

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.
