目前國內最好的柴油發(fā)動機是?What is the best diesel engine currently available in China?

信息摘要:

康明斯發(fā)電機、發(fā)電機組、柴油發(fā)電機、柴油發(fā)電機組、玉柴柴油發(fā)電機組你、上柴柴油發(fā)電機、濰柴發(fā)電機組

柴油發(fā)動機的水箱冷卻液加注口向外在量噴水氣泡,看起來像鍋中燒開了水似的,人們俗稱這種現(xiàn)象叫柴油發(fā)動機“開鍋”了。

一、柴油發(fā)動機高水溫,導致柴油機回水箱水道管高水溫,液體沸騰膨脹,從而加注口噴出,岀現(xiàn)這種情況,建議根據(jù)下面幾個方面檢查處理引起高水溫問題:(出現(xiàn)本問題的情況可能性比較少,多數(shù)是后面的兩個故發(fā)動障)

1、柴油發(fā)動機水管中有空氣,起動后出水管氣阻循環(huán)不暢,會導致水溫上升,間歇時噴水,也有點像開鍋了;

2、柴油發(fā)動機循環(huán)水量不足,在高負荷或負荷運行下,潤滑機油溫度也升高,也會導致水溫不斷上升;

3、柴油發(fā)動機循環(huán)淡水泵損壞;

4、柴油發(fā)動機散熱風扇損壞(缺葉片或葉片邊損壞),導致散熱風量不夠,也會引起水溫不斷上升;

5、柴油發(fā)電機散熱風扇皮帶過松,散熱風扇速度達不到要求,導致散熱風量不夠,也會引起水溫不斷上升;

6、柴油發(fā)動機是開式冷卻循環(huán)系統(tǒng),外循環(huán)水源水位過低(水量不足),淡水泵吸不上水;

7、柴油發(fā)動機是閉式冷卻循環(huán)系統(tǒng),散熱器(水箱)表面積污垢太多,散熱不良等。

二、柴油發(fā)動機氣缸床墊損壞沖掉了,氣道與水道竄通,使缸內高壓空氣進入低壓水道,最終通過冷卻液加注口排出形成氣泡,建議檢查核實,如是則更換氣缸床墊。三、柴油發(fā)動機缸蓋破裂,氣道與水道竄通,使缸內高壓空氣進入低壓水道,最終通過冷卻液加注口排出形成氣泡,建議拆下缸蓋水壓試驗檢查核實,如是則更換缸蓋(一般是不能修復的)。

The coolant filling port of the diesel engine's water tank sprays water bubbles outward, making it look like water has boiled in a pot. People commonly refer to this phenomenon as the "boiling" of the diesel engine.

1、 The high water temperature in the diesel engine leads to high water temperature in the return water pipe of the diesel engine, causing the liquid to boil and expand, resulting in the injection of fuel from the filling port. If this situation occurs, it is recommended to check and deal with the high water temperature problem according to the following aspects: (The possibility of this problem occurring is relatively low, mostly due to the last two engine failures)

1. There is air in the water pipe of the diesel engine, and after starting, the air resistance circulation of the outlet pipe is not smooth, which can cause the water temperature to rise. Spraying water intermittently is also a bit like boiling a pot;

2. Insufficient circulating water in diesel engines can cause the lubricating oil temperature to rise during high load or load operation, leading to a continuous increase in water temperature;

3. Diesel engine circulating fresh water pump damaged;

4. Damage to the cooling fan of a diesel engine (due to missing blades or damaged blade edges) can result in insufficient cooling airflow and cause the water temperature to continuously rise;

5. The belt of the diesel engine cooling fan is too loose, and the speed of the cooling fan cannot meet the requirements, resulting in insufficient cooling air volume and continuous rise of water temperature;

6. Diesel engines have an open cooling cycle system, and the water level of the external circulation water source is too low (insufficient water volume), causing the fresh water pump to be unable to draw in water;

7. Diesel engines have a closed cooling cycle system, with excessive dirt on the surface of the radiator (water tank) and poor heat dissipation.

2、 The cylinder mattress of the diesel engine is damaged and washed away, causing the air passage and water passage to become open, allowing high-pressure air in the cylinder to enter the low-pressure water passage. Eventually, bubbles are formed and discharged through the coolant filling port. It is recommended to check and verify, and if so, replace the cylinder mattress. 3、 The cylinder head of a diesel engine ruptures, causing the air passage and water channel to become open, allowing high-pressure air in the cylinder to enter the low-pressure water channel. Eventually, bubbles are formed and discharged through the coolant filling port. It is recommended to remove the cylinder head and conduct a water pressure test to verify. If so, replace the cylinder head (which is generally irreparable).
