發電機組黑、藍、白廢氣顏色，是可以判斷機組問題的外在現象。燃氣發電機組燃油完全燃燒后，正常排氣顏色一般為淡灰色，負荷略重時為深灰色。燃氣發電機組在工作中，偶爾會出現排黑煙、白煙、藍煙等不正常現象，它是判斷燃氣發電機組故障的條件，分析如下：

　　The color of black, blue, and white exhaust gases from a generator set is an external phenomenon that can be used to determine the problem with the unit. After the fuel of the gas generator set is completely burned, the normal exhaust color is generally light gray, and when the load is slightly heavy, it is dark gray. During the operation of a gas generator set, abnormal phenomena such as black smoke, white smoke, and blue smoke may occasionally occur. This is a condition for determining the fault of the gas generator set. The analysis is as follows:

　　（一）黑煙

　　（1） Black smoke

　　柴油是復雜的碳氫化合物，噴入燃燒室內未燃燒的柴油受高溫分解，形成炭黑。排氣時隨同廢氣一起排出形成黑煙。黑煙是燃燒室內燃料燃燒不完全的表現。其主要影響因素如下：

　　Diesel is a complex hydrocarbon, and the unburned diesel injected into the combustion chamber undergoes high-temperature decomposition, forming carbon black. During exhaust, it is discharged together with the exhaust gas to form black smoke. Black smoke is a manifestation of incomplete combustion of fuel inside the combustion chamber. The main influencing factors are as follows:

　　1、活塞環、氣缸套等磨損活塞環、氣缸套磨損后，引起壓縮壓力不足，使氣缸在壓縮行程結束時，混合氣混合的正常比例改變，使燃油在無氧條件下燃燒，產生積炭。

　　1. Wear of piston rings, cylinder liners, etc. After the wear of piston rings and cylinder liners, insufficient compression pressure is caused, which changes the normal proportion of the mixture at the end of the compression stroke of the cylinder, causing the fuel to burn under anaerobic conditions and produce carbon deposits.

　　2、噴油器工作不良噴油器不霧化或滴油，使燃料不能充分地與氣缸內的空氣混合，也不能充分燃燒。由噴油器工作不良引起的排黑煙現象在燃氣發電機組低速運轉時較明顯。因為低速運轉時氣缸內進氣渦流較弱，油滴或油束被氣流沖散的可能性減少并且停留的時間較長，更容易形成碳黑排出。

　　2. Poor operation of the fuel injector: The injector does not atomize or drip oil, which prevents the fuel from fully mixing with the air in the cylinder and from fully burning. The phenomenon of black smoke emission caused by poor operation of fuel injectors is more pronounced during low-speed operation of gas generators. Because the intake vortex in the cylinder is weaker during low-speed operation, the possibility of oil droplets or oil droplets being dispersed by the airflow is reduced and they stay for a longer time, making it easier to form carbon black emissions.

　　3、燃燒室形狀改變燃燒室形狀的制造質量不符合技術要求，使壓縮余縫過大過小以及活塞位置裝錯，都會使燃燒室形狀改變，從而影響燃油與空氣混合質量，使燃油燃燒條件變壞。

　　3. The manufacturing quality of changing the shape of the combustion chamber does not meet the technical requirements, resulting in compression gaps that are too large or too small, as well as incorrect piston positions, which can cause changes in the shape of the combustion chamber and affect the quality of fuel and air mixing, leading to deterioration of fuel combustion conditions.

　　4、供油提前角調整不當1)供油提前角過大，燃油過早噴入燃燒室內，由于此時氣缸內壓力溫度較低，燃料不能著火燃燒，當活塞上行，氣缸內達到一定壓力和溫度，可燃混合氣燃燒。2)供油提前角過小，噴入汽缸內的燃油過遲，一部分燃料來不及形成可燃混合氣就被分離或排出，隨廢氣排出的燃料受高溫分解，就形成黑煙。

　　4. Improper adjustment of fuel supply advance angle: 1) If the fuel supply advance angle is too large, fuel will be injected into the combustion chamber too early. Due to the low pressure and temperature in the cylinder at this time, the fuel cannot ignite and burn. When the piston rises, the cylinder reaches a certain pressure and temperature, and the combustible mixture burns. 2) The fuel supply advance angle is too small, and the fuel injected into the cylinder is too late. Some of the fuel is separated or discharged before it can form a combustible mixture. The fuel discharged with the exhaust gas is decomposed at high temperatures, forming black smoke.

　　5、供油量過大供油量過大，使進入汽缸內的油量增多，造成油多氣少燃油燃燒不完全。另外，工作負荷過重、燃油質量低劣、工作溫度過低也會引起排氣冒黑煙。

　　5. Excessive fuel supply leads to an increase in the amount of oil entering the cylinder, resulting in incomplete fuel combustion due to excess fuel and insufficient gas. In addition, excessive workload, poor fuel quality, and low operating temperature can also cause black smoke from the exhaust.

　　（二）藍煙

　　（2） Blue Smoke

　　潤滑油進入氣缸，受熱蒸發成為藍色油氣。隨廢氣一起排出藍色煙霧，其主要原因為：1、空氣濾清器阻塞，進氣不暢或油盆內油面過高(油浴式空氣濾清器)。2、燃油中混入潤滑油。3、活塞環對口，4、在機體通向氣缸蓋油道附近的氣缸墊燒毀。5、活塞環、活塞、氣缸套磨損

　　Lubricating oil enters the cylinder and evaporates into blue oil and gas when heated. Blue smoke is emitted along with the exhaust gas, mainly due to: 1. clogged air filter, poor air intake, or high oil level in the oil pan (oil bath air filter). 2. Lubricating oil is mixed into the fuel. 3. The piston rings are aligned, and the cylinder gasket near the oil passage leading to the cylinder head in the body is burned. 5. Wear of piston rings, pistons, and cylinder liners

　　（三）白煙

　　（3） White smoke

　　燃氣發電機組在剛起動時或冷機狀態時，排氣管冒白煙，是因為燃氣發電機組氣缸內溫度低油氣蒸發而形成。冬季尤為明顯。若熱機時，排氣管仍冒白煙，則判斷為燃氣發電機組故障。主要原因如下：1、氣缸套有裂紋或氣缸墊損壞，冷卻水進入氣缸，排氣時形成水霧或水蒸氣。2、噴油器霧化不良，有滴油現象。3、供油提前角過小。4、燃油中有水份和空氣。5、噴油泵壓力過低或活塞、氣缸套等磨損嚴重引起壓縮力不足。

　　When the gas generator set is just started or in a cold state, white smoke is emitted from the exhaust pipe due to the low temperature inside the cylinder of the gas generator set and the evaporation of oil and gas. Especially evident in winter. If white smoke still appears from the exhaust pipe during heating, it is judged as a malfunction of the gas generator set. The main reasons are as follows: 1. Cracks in the cylinder liner or damage to the cylinder gasket allow cooling water to enter the cylinder, resulting in the formation of water mist or steam during exhaust. 2. Poor atomization of the fuel injector, with oil dripping phenomenon. 3. The fuel supply advance angle is too small. 4. There is moisture and air in the fuel. 5. Insufficient compression force caused by low fuel injection pump pressure or severe wear of pistons, cylinder liners, etc.
