סיטרואן c4 2011 גיר רובוטי מנוע 156 thp

[לומד]

היי שלום לכולם 

ברשותי סיטרואן סי 4 דגם אקסלוסיב עם מנוע 156 thp הרכב נסע 100,000 ק"מ.

לאחרונה כשהאוטו קר הוא משמיע רעש מאוד חזק מכיוון המנוע/גיר וכשהאוטו מתחמם הרעש חולף....

המעניין הוא שבנסיעה כשהאוטו קר הוא מרעיש מאוד מאוד רגע לפני העברת הילוך ואז שקט וחוזר חלילה... עד שהמנוע חם 

למשהו יש רעיון אני מצרף הקלטה 

זה בעיקר הרעש שנמצא ברקע שעולה יורד...

זה מנוע שידוע בסוג הבעיות האלה:

What are the causes of 1.6 THP timing failures?

1.6 THP engines are usually powerful, and hence – high torque, averaging 240 Nm. Thereby, greater stresses in the timing arise in the crank system. The one used in 1.6 THP is equipped with a single row chain, even though two rows are already used today. It looks like a bicycle one and it cannot withstand the heavy loads generated by the engine, so it pulls out quite quickly (even 2 cm for 100,000 km).

Another factor influencing timing wear is a faulty chain tensioner, which cannot maintain the oil pressure long enough. As a result, the pin retracts too quickly when parked and loosens the chain. The problem is additionally exacerbated by the very low viscosity oil (0W-30 or 5W-30) used in THP engines, which makes it difficult to maintain tightness, and the oil filter is too small.

How to recognize the problem?

The first symptom is usually the characteristic rattling noise of a cold engine. At that time, the oil that had previously fled from it has not reached the tensioner yet. After a while, the rattling stops, indicating that the tensioner has filled with oil. If the chain has already pulled out sufficiently, this may result in poor engine running smoothness and poor performance, and in extreme cases, even starting difficulties.

 

Can it be prevented?

There is no way that can eliminate the described problem one hundred percent. Experienced mechanics, however, have found a solution that can extend the interval between timing changes – they install a tensioner with an improved design (with the oil supply hole closer to the screw head) or remake it themselves so that the piston does not retract.

The chain itself cannot be treated as a long-lasting element and can not be replaced even every 100,000. km. In addition, check the oil level frequently and replenish it more often than recommended by the manufacturer (i.e. 30,000 km).

סליחה שאני מקפיץ.

 

מה אומר על הרכב עדיין יש לך אותו? אומרים רכבים נוחים, כיום המחירים ברצפה שווה או רכב מאוד יקר לתחזוקה?
