The use of cars，Oil missing failures often occur，It will directly affect the technical performance of the car，Cause lubricating oil、Waste of fuel，Consumption power，Affecting car Rong neat，Cause environmental pollution。Due to oil leak、Reduction of lubricating oil inside the machine，Lead of poor lubrication、Cooling insufficient，It will cause early damage to the parts，Even left an accident hidden danger。

1. The main cause of oil leakage in common vehicles

1、Product (accessories) Quality、The material or process is not good; the structural design exists。

2、Pretend to be high -speed improper，Uncooked with the surface，Cushion damage、Shift or fail to install it in accordance with the specifications of operating procedures。

3、Tasmly nuts of tightening nuts、Slip Degreed or Looster Kuang, which causes work failure。

4、Live -wear of wear for long -term use of sealing materials，aging deterioration、Deformation failure。

5. Add too much lubricant, excessive oil surface or error oil.

6、parts (side cover、thin wall parts) Joint surface deflection deformation、Broken shell，Make the lubricant exudate。

7、ventilation plugs、After the unidirectional valve is blocked，Due to the effect of air pressure difference in the box shell，often causes oil leakage。

2. Prevention of vehicle oil leakage measures

1. Pay attention to the pad.

Automotive static place (such as the joint surface of each Seabetjunction、End -end cover、Shell、Cover、Graphic Enamel Cover Plates, etc.) The pads between parts and parts play a leak -proof sealing effect。If the material、Production quality and installation does not meet technical specifications，No sealing and leak -proof effect is not available，Even an accident。If the oil bottom shell or the valve cover，Due to the large contact area, it is not easy to compact，As a result, oil leakage。Pay attention to putting properly when disassembling，Check carefully，and assembled according to specifications。

2、All types of fastening nuts on the car need to be tightened according to the prescribed torque。

The overpowered pad will leak; too tight will make the metal around the screw holes raised or twist the filament to cause oil。Another，Oil bottom shell Put the oil stuffing if it is not tightened or returned to the pine，It is easy to cause oil loss，Then the "burning tile holding shaft" machine loss accident。

3, timely replace the failure oil seal.

Many dynamic sites in the car (such as oil seal、O -type circles) will not be installed，Black and oil seal blade different heart，Polying and throwing oil。Some oil sealing will lose elasticity due to the aging of rubber for a long time。Discovery leak should be updated in time。

4、Emperor automobile parts can produce a wear limit (such as piston and cylinder, etc.)

As a result, high -pressure gas in the burning room enters the crankshaft box，Forced the oil to leak outside。Therefore，When the exhaust gas is severe at the oil mouth cover，Should be maintained or replaced early。

5. Avoid blocking the unidirectional valve and ventilation valve.

As a result, the temperature in the box shell increases，Oil and gas is full of space、Can can be discharged out of the canal，increase the pressure consumption of lubricating oil in the box shell to increase the consumption of lubricating oil and the replacement Seabetcycle。After the engine ventilation system is blocked，Added the motor resistance of the piston，Increase fuel consumption。Due to the effect of air pressure difference in the box shell，often causes oil leakage。Therefore, the vehicle needs to be checked regularly、Dredging、Cleaning。

6. Properly solve the sealing of various types of oil pipes.

Automotive pipe tube nuts often disassembled，Easy to slide on the filament and loosen;，The central line of the two cone faces does not coincide with poor contact;，As a result, it will cause oil leakage。Replace the joint tube nut，Use the grinding method to solve its cone sealing，Press the nut and solve the seal。

7. Avoid the wheels from shaking oil.

Too much grease in the hub bearing and lubrication in the cavity，or the oil sealing assembly is inappropriate，Poor quality and aging failure; the temperature of the wheels caused by frequent braking;。Therefore, the useful "empty cavity lubrication method"，Dredging the ventilators，Strict selection of high -quality accessories，and assemble and high -speed in accordance with process specifications。

3. Maintenance and maintenance points for vehicles

Pretend to be assembled under extremely clean conditions，Part of the part of the part without bumps、No scratches、Bond and other attachment; strict operating regulations，Sealing parts should be installed correctly，Prevent deformation from being unable to be in place; master the performance specifications and requirements of the sealing parts，Replace the disorders in time;，Use sheet metal cold for correction; a shaft hole parts that are easily worn can be placed with metal spray、Welding repair、Adhesive、Mechanical processing and other processes to reach the original size; try to use sealing glue，If necessary, you can use paint to achieve the ideal sealing effect; nut slide fold、Loostelling should be repaired or seabet ioreplaced with new items，Turn to the prescribed torque; check the appearance quality carefully before assembly of rubber sealing;，Avoid knocking and deformation; add lubricating oil according to regulations，Regular cleaning and clearing the ventilators and one -way valve。As long as the above points are achieved，The problem of the vehicle's oil leakage is completely cured。
