1.9. Hydraulic compensators of gaps of valves of the engine of 1,6 l
The main malfunctions of hydraulic compensators of gaps of valves, the reasons and methods of elimination are given in the table.
Malfunction
|
Possible reasons
|
Elimination method
|
||
• Temporary noise at start of the cold engine | Normal phenomenon | Noise disappears after warming up of engine oil and achievement of normal pressure | ||
• Continuous noise after the engine was not started within 48 hours | Oil from cameras of hydraulic compensators of gaps of valves flowed out and air got to them | Noise will disappear in 15 min. operation of the engine when the bent shaft of the engine reaches the frequency of rotation of 2000-3000 min.-1
| ||
• Continuous noise after launch of the engine and replacement of a head of cylinders | There is not enough oil in oil channels of the engine | |||
• Continuous noise after long launch of the engine a starter or by method of towage | Oil from cameras of hydraulic compensators of gaps of valves flowed out and air got to them | |||
• Continuous noise, after replacement of hydraulic compensators of gaps of valves | ||||
• Continuous noise, at an idling frequency after the movement at a high speed | Level of engine oil too low or too high | Check the level of engine oil | ||
A large amount of air is dissolved in oil after the high frequency of rotation | Check system of supply of oil | |||
Deterioration in properties of engine oil | Check quality of oil and, if necessary, replace it | |||
• Noise continues more than 15 min. | Low pressure in the lubrication system | Check quality of oil and, if necessary, replace it | ||
Hydraulic compensators of gaps of valves are faulty | Remove a head of cylinders and, pressing hydraulic compensators of gaps of valves, check the size of their compression |
