MTU柴油發動機的結構與原理

 國家標準規定,在內燃機銘牌上的標定功率分為下列四類：

 (1)15分鐘功率。即內燃機允許連續運轉15分鐘的最大有效功率。是短時間內可能超負荷運轉和要求具有加速性能的標定功率,如汽車、摩托車等內燃機的標定功率。

 (2)1小時功率。即內燃機允許連續運轉1小時的最大有效功率。如輪式拖拉機、機車、船舶等內燃機的標定功率。

 (3)12小時功率。即內燃機允許連續運轉12小時的最大有效功率。如電站機組、工程機械用的內燃機標定功率。

 (4)持續功率。即內燃機允許長時間連續運轉的最大有效功率。

對于一臺機組,柴油機輸出的功率是指它的曲軸輸出的機械功率。MTU柴油發動機的結構與原理|MTU柴油發動機的結構與原理維修技術|MTU柴油發動機的結構與原理資料|MTU柴油發動機維修服務商根據規定,電站用柴油機的功率標定為12小時功率。即柴油機在大氣壓力為101．325kPa,環境氣溫為20℃,相對濕度為50％標準工況下,柴油機以額定轉速連續12小時正常運轉時,達到的有效功率,用Ne表示。

一般進口柴油機,其功率分為主用功率和備用功率,兩者功率之比為0．91：1,相當于我國12小時功率和1小時功率之分。

柴油機是內燃機的一種類型,是現代廣泛應用的發動機之一。它是將柴油噴射到汽缸內與空氣混合燃燒得到熱能轉變為機械能的熱力發動機。目前,通信和其他國民經濟部門的自備電站主要依靠它作動力帶動同步交流發電機發電。當市電停電時,依靠該機組發電,提供交流電源,保證通信設備或其他電器的用電。本章就MTU柴油發電機組柴油機的結構和原理分別進行簡單的介紹。

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.
