The vehicle maintenance and repair that there are you not to know here maintains knowledge, have the real story of those false appearance backside more. If you want to become a true car to amount to a person, one of best ways that your complement knowledge can be here. About the car those are foregone, sealed, curious, of muddled, you can find the solution here, no matter still be opposite to you for me, this is a new beginning probably!
If the word person of car assimilate to, so maintenance technician should be a doctor. Although a content of frozen steely load one's writing with fancy phrases, another is the advanced animal of vivid. But breakdown and fall ill those who face is one covers a region, cannot leave to hope to hear forever ask
Breakdown description
Even if be to have an ala child board cloth is enclothed, hale automobile body line still lets a person can detection this is a BMW. Look around in automobile body all round do not have maintenance technician only, the treasure wagon that still change of this business suit is walked on advocate. The leather shoes that can give off light in dark night seems to do not have the relation of a wee bit with fat workshop, can jump into same the breakdown that the reason all of a picture depended on this BMW encountering very strange flower, be in namely idle fast and urgent when quickening, this BMW engine was given out be similar to whistled howl cry.
Diagnostic process
Actually abnormal knocking is in inchoate not be so easy judgement, develop in science and technology nevertheless flying today, the application of new technology can accomplish get twice the result with half the effort really. Maintenance technician is operating a respect to had been been close to exceedingly with the doctor, stethoscopic application can help me find abnormal knocking source quickly. Mere after ten minutes, I decided the origin of whistle with respect to the lock, it alleviates namely the PCV a powerful person of crankcase pressure.
This stethoscopic equipment has been very common, very much after all model can have different abnormal knocking breakdown to appear. And its strong point can magnify abnormal knocking source namely, screen of will other sound is dropped. Still can undertake modulatory to receiving acoustical frequency, accomplish more the diagnosis with accurate essence. Science and technology is the first productivity, this word I am deep really have experience.
Begin to maintain
This BMW is disassembling now spiracle room overspreads a lid, because PCV a powerful person follows spiracle room to overspread a lid compositive arrive one case, I must change lid of cover of whole valve room finally will solve aggravating abnormal knocking.
Since be BMW,was not to break away from VANOS electric machinery for certain, what never had thought the mankind can play lever is so nifty. Adscititious 6 ignition coil, it is OK really collect becomes a dish of dish. See here, believing you also know the project is measured is to have how big.
Top of new spiracle room cover is born in corner Liyi Yi brightness, on popular engine, this PCV a powerful person can have changing alone. What no matter be maintenance cost and labor intensity,should compare BMW is a lot of lower, also may be BMW nevertheless feel oneself PCV a powerful person is essential won't bad.
The capable person that spiracle room cover covers is the project is plastic character, although hardness is very big weight is very light, but love to be out of shape very much really, also be leakage of numerous engine oil nods a among them. The fittings do manual work of former plant is very outstanding, not let sb down 1000 yuan piece price.
Disassembled the case that spiracle room wraps a lid to let me be able to the opportunity sees interior of engine valve room, can generalize simply with 4 words, it is glittering and translucent get rid of is appeared. The condition of engine is first-rate, cannot see heavy greasy filth exists basically, visible car advocate maintain to this car proper, and care has add.
Actually my hereinbefore did not say to install this valve room to overspread a lid is the job of patience of an unusual trial, although this is,one looks be like simple however cannot again simple movement. I spent half hour fully, just overspread spiracle room the lid to be put completely to engine. What imagine with you because of it is completely different, resembling is to play Lu Ban to lock up for the first time, true need is accomplished not arrogant not impetuous.
Though installation is pigheaded screw, still also having strict ship-fitter nevertheless art. 23 bolt on cover lid have spiracle room each times to screw fixedly ordinal, and have screw pitching moment asks strictly, for 8.6 ± rice of 0.6 oxen · .
Good, although not be very harmonious on new old rate, but breakdown is perfect settlement now.
Breakdown uncovers secret greatly
Said so much can be subject, how does my can next detailed explanation whistle come.
Yellow green violet part the group is the most magical thing like was being become, it is the PCV a powerful person of engine. PCV a powerful person is collected come from the engine oil vapour at engine interior, one part interiorly undertakes circumfluence turns engine oil regurgitate into engine, another part gas is introduced to enter gas manifold to participate in combustion, the purple interface in the graph follows intake duct photograph to join namely. It is insufficient that the participation with engine oil pure vapour affirms into gas combustion, start machine movement to rise after all need thousands of turn, in-house pressure is very great still. Appeared so maize disc will alleviate spiracle room pressure, in discharging the vapour of over atmosphere, and the disc that abnormal knocking source is this yellow.
Light says no use, I decomposed this disc thoroughly, meaning developing the source with common people real whistle. Maize diaphragm should be a whole originally, had been become by complete cent now two half, cause the cause of this kind of result, high temperature also has natural ageing.
Of the environment it is huge to the harm of the component badly, interior of whole PCV a powerful person had been bestrewed accumulate carbon, if not be to howl calls abnormal knocking to undertake changing, the meaning that actually it exists originally also is done not have how old.
Abnormal knocking majority appears in idle fast and urgent quicken level, spend because of vacuum of intake duct of this moment engine the biggest. The sealing of PCV a powerful person of in good condition nondestructive is very strong, the air besides diaphragm does not have a law to enter engine. And diaphragm appeared now damaged, air can enter engine as a result of powerful attraction, when passing diaphragm, shake with respect to meeting generation, namely the whistle that we hear.
The thought decides action, the cerebral sea mile that maintaining technician actually has a pair of such picture.
One: Diaphragm of PCV a powerful person became bad absolutely not only pure abnormal knocking appears, accompany and come still have a lot of trouble!
1 engine shakes
After the diaphragm when PCV a powerful person is broken, much air swarms into engine in, can cause mixture gas to slant rare. When cool Che Qi is moved, can feel shake apparently, engine of as time passes gives malfunction code with respect to meeting newspaper.
2 excessive consumption of fuel and oil
Engine can work normally, air and petrolic scale need maintain a stable position. Take energy of life now much, want much fuel injection necessarily. When the river rises the boat goes up too, nature of oily bad news also went up accordingly.
2: About safeguarding
1 how to resolve this trouble?
At present till still settle way without what compare be to one's profit, can be to undertake changing only. The service life that balata material cannot regain a gender character to bring about it once, to BMW model, the life that spiracle room cover covers also once.
2 how to prevent damage of PCV a powerful person?
The attaint of PCV a powerful person and working environment have immediate concern, good engine oil will naturally reduce pressure of vapour of engine interior engine oil, prolong the service life of PCV a powerful person then.
3: Write finally
This breakdown is actually commonner on heart department model, after all the engine work temperature with heart department higher model can bring very great greater crankcase vapour pressure certainly. Nevertheless also unlike concern, majority of this kind of state appears in the kilometer to count larger model to go up, this BMW before already travel nearly 160 thousand kilometer, so big kilometer counts some breakdown also are unavoidable.
