seabet loginSpeed speed of modern engine、Increases of the overlapping angle of the air valve and the compression characteristics，Increase the vacuum of the engine。When a certain new engine slows down，The vacuum of aspiration is as high as 25 inches (635mm) mercury degree (old engine design = 508mm Hryk -column height)。High vacuum needs to develop a new seabet myoil ring，Effective sealing on both sides of the piston rings (above and below)，Avoid leakage from the sides of the oil ring on both sides of the oil ring and back on the high vacuum and deceleration time。This reason is often a main reason for the blue smoke or high fuel consumption，So，When you need it，Oil ring with side sealing ability is very important。2. There are too much oil in the oil bottom shellDue to the error of insertion from the ruler，Failure to seat to the end，As a result, the measured oil level is lower than the actual oil level，So add new oil，Make the oil level too high。If the bottom end of the connecting rod of the pressure lubrication engine is touched, the oil surface，or the oil ring of splashing the engine is immersed in the oil pool too deep，It will cause excess oil to throw it to the cylinder wall，Enter the burning room。3. The compatible pistons are not suitable for engine types or work typesIf the size of the piston ring is selected (such as, 0.020 " The increased piston ring is used in the cylinder that is increased 0.040 " ，Due to improper cooperation of the two，It is impossible to scrape the oil in the upper part of the cylinder，It will immediately cause the phenomenon of oily oil。The same，The gap between the bottom of the piston ring and the ring groove also increases，Further increase the oil consumption，For the reason, as described in#26。Different types of engines，Different working conditions，Pistons group that requires a variety of different special design and manufacturing。Each type of piston ring group，Made for a certain purpose，If used in the wrong place，It will not be able to control the engine oil consumption of the engine。The correct piston ring group is very important。4. Dirty oilDo not change oil for oil change cycle，Improper maintenance of the oil filter will make the oil dirty，Make motor oil blocked the piston、The oil gap around the piston ring，Caused by the reason for the reasons#17。Dirty oil will also cause bearing、cylinder、Pistons、The wear of the piston ring intensified。These wear components，Like the specific explanation of each of the previous one，will lead to rising fuel consumption。Special attention: Dirty oil itself is higher than the consumption of clean oil。5. The air valve is positive when lagging backThe lagging air valve is right time，Make the intake valve closed for a long time after the start of the aspiration.，The vacuum in the cylinder rises，Add motor oil from the piston and ring，The probability of burning the burning room in the upper part of the cylinder inhalation。6. During the installation of the piston ring, the gap between the circle end is too smallWhen installing a new piston ring，Be careful，At the minimum diameter seabet appof the cylinder，The Pistons still leave enough circumcision gap，Compensation thermal expansion。Usually the gap required for the cast iron ring of the vehicle engine is 0.003-0.005 inch/inch aperture。Because the combustion gas from the burning room is directly endured，The heating speed and working temperature of the piston ring are higher than the cylinder。The cylinder wall is due to the effect of water cover，Low temperature。This means that the piston rings expand more，Therefore, there must be a gap to compensate -that is, the gap between the round end -otherwise，In the engine work，The end surface of the Pistons will interfere with the cylinder wall，impact，Then cause abrasion、Adhesive wear，leading to rising fuel consumption。If the engine continues to run，Especially when the load is heavier，Adhesive wear will be more serious。The end surface of the piston ring is pressed inward to the Pistons，Gap in the ring and cylinder wall increases，Burning room High temperature High pressure Burning gas directly burn the lubricant on the wall of the cylinder，Entering the oil bottom，greatly increased the oil consumption。Serious interference even causes the piston ring to break，The consequences generated as described in#27。Excessive gap between the long -end of the pobbilities will also cause increased oil consumption。7. Pistons that wear or breakIf the piston ring is broken or over -worn，Causes compression stress and gap cannot be maintained，Will inhale excess oil into the burning room during the inhaling stroke，Burning Qi running under the piston when doing the journey。Both of them cause pistons、cylinder wall、Burning of the oil around the piston ring、Carbonization。Fracture piston ring is more destructive，Broken sketch with a sharp mouth is likely to cut into the side of the piston ring groove，Destruction caused by the ring shore and the thorough damage of the piston。When the engine is repaired，The worn piston ring should be replaced immediately，instead of re -use。The new piston ring has a fast positioning surface，You can immediately control the consumption of the oil。The piston ring used，Even if only slight wear，Since the surface has been polished，Can't position it appropriately，It will also lead to excess oil consumption。8. Pistons The adhesive ringObviously，The piston ring of the adhesive ring cannot control the oil。So，Try to avoid this situation as possible。First，The installation of the Pistons should ensure the correct piston ring gap，This，When engine work，The Pistons are still active in the ring groove at the operating temperature。In addition，Make sure the piston ring is cleaned during the installation of the piston ring，Dust Seabet-free soil particles，Otherwise，may cause the piston ring sticky。Third，Select oil products with excellent performance，Reduce carbon deposits、sludge、The generation of paint film。fourth，Discoral oil exchange、Cleaning the oil filter。Fifth，Avoid the engine overheating。9. Time gear or chain wearThe wear of the timing gear or chain will cause the timing of the air valve and crankshaft。Excessive side gaps caused by wheel teeth or chains，Make the engine adjustment cannot be realized: the timing and the next lap may be different。When the movement of the air valve and the piston is not synchronized，It will cause excessive oil consumption。The reason is that over -vacuum in the burning room will draw a large amount of oil into，Burn out。10. Oil pressure is too highIncorrect oil pressure setting，Failure of the security release valve，All will cause excessive oil pressure。As a result, the engine is infiltrated by excessive oil，Generate results like bearing worn。11. Oil viscosityThe oil viscosity used by the engine is too thin，May cause high oil consumption。Please refer to the vehicle maintenance manual，Choose the right oil viscosity according to the driving conditions and environmental temperature。12. Pistons DesignSome latest engines to meet the emission requirements，The design of the new piston ring was adopted。Sometimes，This design will occur mild "tap"。Sometimes it will increase motor oil consumption。13.In the new engine design，Frequent composite materials composed of metals and other materials，Different from the degree of thermal expansion and contraction due to different materials，After running for a long time，Food and sealing will generate heat stress fatigue or rupture，also leading to an increase in fuel consumption level。14.Most new engines are equipped with explosive sensors，to adjust the timing system to reduce emissions，Improve the power and performance of the engine。Cree ignition in advance，It is due to the burning process，Caused by the early ignition of fuel。Early ignition leading to a sharp increase in pressure accumulated on the piston，Destroy the normal exercise of the piston ring，Seal the piston ring on the top and bottom of the piston ring，In the end, increase gas and fuel consumption through the piston ring。Due to the failure of the air intake flow sensor and the sensor fault of the throttle position, the same problem。15. Modify the engine by itselfThe user's self -improvement of the modification of the engine performance and the spare parts used in inventory or the modification part of the engine performance/power on the engine，The possibility of increasing the problem of high fuel consumption of the engine。16. Dilute fuelIf there is no complete seabet loginburn fuel into the lubrication system，Machine oil will become thinner and easier to volatilize，This will lead to higher oil consumption。Excess fuel may be leaked due to fuel nozzle、Problem fuel pump、High or too much idle operation，Enter the lubrication system and mix with the oil。17. Improper operation of speeding operationMakes the engine at a speedy operation without speeding，Many different reasons related to this，All will lead to rising engine fuel consumption。These situations include crawling and frequent start and stop in urban traffic，You can also refer to the reason 36。18. The turbocharger seal leakSeal leakage of the turbocharger，will inhale the oil into the burning room，Boil and form carbon，Obstructing the normal work of the engine，and further lead to more oil consumption。19. High intake resistanceExcessive intake system resistance，will increase the vacuum in the engine，and can increase the oil consumption，As described in item 24。The severe blockage of the air filter is an example of this situation。20. The engine luggingLugging refers to allowing the engine to run at low speed when high -speed (larger power/torque) should be used，This will cause the piston to bear greater pressure，and can cause increased oil consumption。
