不同的發動機有正常的油耗值，不同的發動機型號的正常油耗是不同的。下麵好色TV下载安装來看看發動機“燒”機油的原因。

Different engines have normal fuel consumption values, and the normal fuel consumption of different engine models is different. Now let's take a look at the reason why the engine "burns" oil.

1、外漏油

1. External oil leakage

漏油的原因有很多，包括：油路、排油口、油底殼墊片、氣門蓋墊片、油泵墊片、燃油泵墊片、正時鏈蓋密封件和凸輪軸密封件。上述可能的泄漏因素不容忽視，因為即使是很小的泄漏也會導致大量的油耗。例如，每6秒一滴意味著每100公裏耗油0.56升。更好的檢查泄漏的方法是在發動機底部墊一塊淺色布，在啟動發動機後檢查。泄漏的位置可以通過布上油滴的位置來判斷。

There are many reasons for oil leakage, including: oil circuit, oil drain, oil pan gasket, valve cover gasket, oil pump gasket, fuel pump gasket, timing chain cover seal and camshaft seal. The above possible leakage factors should not be ignored, because even a small leakage will lead to a lot of fuel consumption. For example, a drop every 6 seconds means that the fuel consumption is 0.56 liters per 100 kilometers. A better way to check the leakage is to pad a light colored cloth at the bottom of the engine and check it after starting the engine. The locations of leakage can be judged by the locations of oil drops on the cloth.

2、前後油封故障

2. Front and rear oil seals failure

前後主軸承油封損壞肯定會導致漏油。這種情況隻有在發動機負載運行時才能檢測到。主軸承油封磨損後必須更換，因為像漏油一樣會造成高泄漏。

Damage to the oil seals of the front and rear main bearings will definitely lead to oil leakage. This condition can only be detected when the engine is running under load. The main bearing oil seal must be replaced after wear, because it will cause high leakage like oil leakage.

3、主軸承磨損或失效

3. Wear or failure of main bearing

磨損或故障的焦化好色先生在线观看主軸承會激起多餘的油並撞到氣缸壁上。隨著軸承磨損的增加，更多的油被拋出。例如，如果軸承設計遊隙為0.04mm，提供正常的潤滑和冷卻，如果能保持軸承遊隙，拋出的油量是正常的，不會損壞軸承。

Worn or faulty main bearings of coking generator set 8 will stir up excess oil and hit the cylinder wall. As bearing wear increases, more oil is thrown out. For example, if the bearing design clearance is 0.04mm, normal lubrication and cooling are provided. If the bearing clearance can be maintained, the amount of oil thrown is normal and will not damage the bearing.

當間隙增加到0.08mm時，拋出的油量將是正常量的5倍。如果將間隙增加到0.16mm，則拋出的油量將是正常量的25倍。如果主軸承噴油過多，會使更多的油濺到氣缸上，使活塞和活塞環無法有效控製油量。這會導致活塞和活塞環上出現燒油或積碳。

When the clearance increases to 0.08mm, the amount of oil thrown will be 5 times the normal amount. If the clearance is increased to 0.16mm, the amount of oil thrown will be 25 times the normal amount. If too much oil is injected into the main bearing, more oil will splash onto the cylinder, making the piston and piston ring unable to effectively control the oil volume. This will cause oil burning or carbon deposition on the piston and piston rings.

通常，如果主軸承上的油流失過多，連杆軸承就會缺油，導致在某些低速條件下，油在氣缸壁上的濺射不足，導致活塞環和活塞磨損，發動機不能高速運轉。是時候控製油了。因此，主軸承磨損的後果是高油耗。

Usually, if the oil on the main bearing is lost too much, the connecting rod bearing will be short of oil, resulting in insufficient sputtering of oil on the cylinder wall under some low-speed conditions, resulting in wear of piston rings and pistons, and the engine cannot run at high speed. It's time to control the oil. Therefore, the consequence of main bearing wear is high oil consumption.

4、連杆軸承磨損或損壞

4. The connecting rod bearing is worn or damaged

連杆軸承遊隙對油的影響與主軸承類似。此外，機油更直接地噴射到氣缸壁上。磨損或損壞的連杆軸承會導致過多的機油濺到氣缸壁上，導致設計用於控製正常機油量的活塞和活塞環無法有效控製多餘的機油，從而使多餘的機油進入燃燒室和被燒毀，即油耗高。注意：軸承遊隙不足不僅會導致自身磨損，還會導致活塞、活塞環和缸壁磨損。

The influence of connecting rod bearing clearance on oil is similar to that of main bearing. In addition, the oil is sprayed more directly onto the cylinder wall. Worn or damaged connecting rod bearings will cause too much oil to splash on the cylinder wall, resulting in the piston and piston ring designed to control the normal amount of oil can not effectively control the excess oil, so that the excess oil enters the combustion chamber and is burned, that is, the oil consumption is high. Note: insufficient bearing clearance will not only cause wear, but also cause wear of piston, piston ring and cylinder wall.
