燃氣發電機組工作過程中會將發電機將機械能轉化為電能，其控制器在發動機與發電機工作過程中擔任著控制、監測以及保護的功能，以保障發電機組能持續、穩定的運行，并在故障時發出指令停止發動機以保護整個系統。下面就來講講燃氣發動機組做功的四個步驟。

During the working process of gas generator set, the generator will convert mechanical energy into electrical energy. Its controller plays the role of control, monitoring and protection during the working process of engine and generator to ensure the continuous and stable operation of the generator set, and sends the command to stop the engine in case of failure to protect the entire system. Now let's talk about the four steps of the gas engine unit.

1、進氣沖程：

1. Intake stroke:

曲軸旋轉，通過連桿帶動活塞下移，同時進氣門打開。經空氣和氣體燃料通過混合器均勻混合后，被吸入氣缸，當活塞到達下止點時，氣缸內部充滿混合氣。

The crankshaft rotates, driving the piston down through the connecting rod, and the inlet valve opens at the same time. After the air and gas fuel are evenly mixed through the mixer, they are drawn into the cylinder. When the piston reaches the bottom dead center, the cylinder is filled with mixed gas.

2、壓縮沖程：

2. Compression stroke:

曲軸在飛輪慣性作用下被帶動旋轉，通過連桿推動活塞由下止點向上止點運行，同時進排氣門關閉，混合氣被壓縮。

The crankshaft is driven to rotate under the inertia of the flywheel, and the piston is driven to run from BDC to TDC by the connecting rod. At the same time, the intake and exhaust valves are closed, and the mixture is compressed.

3、做功沖程：

3. Power stroke:

活塞運行至上止點時，火花塞在點火信號發生器和點火圈所產生的高壓電流作用下產生火花，點燃氣缸內的可燃氣。燃燒時產生的高溫、高壓氣體推動活塞下行，通過連桿帶動曲軸旋轉，對外做功傳遞扭矩。

When the piston runs to the top dead center, the spark plug generates sparks under the action of the high-voltage current generated by the ignition signal generator and the ignition ring, and ignites the combustible gas in the cylinder. The high temperature and high pressure gas generated during combustion pushes the piston downward, drives the crankshaft to rotate through the connecting rod, and transmits torque through external work.

4、排氣沖程：

4. Exhaust stroke:

活塞從下止點往上止點運動，此時排氣門打開，進氣門關閉。氣缸內燃燒后的廢氣被活塞推出，沿排氣道排出氣缸外。

The piston moves from BDC to TDC. At this time, the exhaust valve is opened and the inlet valve is closed. The combustion exhaust gas in the cylinder is pushed out by the piston and discharged out of the cylinder along the exhaust duct.

5、上述過程的重復進行，使發動機連續不斷的運轉。

5. Repeat the above process to make the engine run continuously.
