Tar éis an carr bhí ionad nua ola % 2c an inneall fuaim tháinig níos airde % 2c cad% 27s ag dul on% 3f Rinne tú athraigh an falsa ola % 3f
An tar éis eagarthóir go hachomair tugann sé isteach an 7 culprits sin cúis an t-inneall torann go a bheith níos airde tar éis athrú an ola.
1. An iomarca i bhfad ola
There are also standards for engine oil filling, not that the more the better, if the amount of engine oil filling is too much, it will generate more resistance to the rotation of the crankshaft, thereby the power output and increasesing fuel consumption. The amount of engine oil entering the combustion chamber is increased, which increases the carbon deposit in the combustion chamber, increases the piston gluaiseacht friotaíocht% 2c agus laghdaíonn an inneall cumhacht . Ag an céanna am % 2c beidh sé freisin cúis an aer-bhreosla cóimheas de an dócháin seomra go athrú % 2c méadú an dóchúlacht de knocking% 2c agus an torann beidh freisin méadú dá réir sin.
2. Measartha carbón sil-leagan
An níos sine an inneall ola is% 2c an tinner sé agus an níos mó carbóin taiscí . Má an inneall ola is tanaí % 2c tá sé éasca a rith as an inneall ola 2c cúis níos mó agus níos mó carbóin taiscí. Nuair an nua ola tá ionad % 2c an inneall an inneall torainn is cúis ard inneall torann . Tá sé molta le úsáid ard-ghrád gásailín to drive at high speed. It is best to keep running above 2500 rpm and open a box of high-grade oil should improve. Of course, coisctheach cleaning can also be beried out.
3. Ba chóir go mbeadh an slaodacht de an t-inneall ola oiriúnach oiriúnach
Different gráid de inneall ola tá éagsúla saintréithe % 2c agus a íseal-teocht tosaithe agus ard-teocht frith-chaitheamh agus greamaitheacht airíonna freisin tá éagsúla léirithe . An slaodacht de an t-inneall ola inbhéartach comhréireach leis an teocht . Nuair a an inneall inneall is fuar 2c an slaodacht de an inneall ola is thicker% 2c sé beidh cúis breise caillteanas go an tosaithe mótair agus ceallraí. Mar sin féin% 2c más rud é an inneall ola tá ró tanaí % 2c sé beidh sé deacair foirm a a leordhóthanach cosanta scannán faoi ard teocht oibriú % 2c mar thoradh air neamhleor lubrication% 2c toradh i méadaithe caitheamh de an meaisín páirteanna . Má an feithicil lámhleabhar molann 5W % 7b% 7b% 7d% 7d % 2c an inneall torann thiocfaidh chun bheith louder% 2c ansin an úinéir riachtanais a íoc aird . Tá sé molta chun roghnaigh an ola go bhfuil molta ag an feithicil lámhleabhar.
4. Ola meascadh
This situation is also relatively common, because different brands use different technical formulas, which may produce adverse chemical reactions and change their own characteristics, thereby causing wear and tear on the engine and increasing noise. It is recommended that riders should not mix oil and try to use the same brand of oil. In case of special circumstances, if you change to a different brand of oil, it is best le úsáid an céanna branda de ola.
5. Thángthas falsa inneall ola
This kind of situation is also very likely to happen, because the novice driver added inferior engine oil when maintaining his car. Because the "fake" engine oil has very poor anti-wear, cleaning, and lubrication protection properties, the engine pressure is too high, resulting in increased wear and noise. As a consumer, you need to know some relevant anti-counterfeiting knowledge, not just hearsay, but know how to idirdhealú a dhéanamh an barántúlacht de inneall ola.
6. Tá an fuaim de an fuar carr ard agus gnáth
Most of the engine oil in the cold car state returns to the oil pan. At this time, the internal components of the engine lack lubrication, and the engine temperature will drop when the the cold car is started. The reason for the speed will cause the noise to be too loud, but after the car is warmed up, the noise speed will drop again, which is normal. If it doesn% 27t tuairisceán go gnáth tar éis téamh suas an carr % 2c I fios tú seiceáil sé amach.
7. Síceolaíoch éifeacht
This should account for the majority. Human hearing has errors in different environments. It is impossible to judge the loudness of the sound by the ear alone. It is best to measure it with a decibel meter. From the technical point of view of oil slaodacht, the noise of 5W-20 and 5W-30 engine oil will be be slightly louder when driving in urban areas, and the torann beidh beagán níos ísle nuair tiomáint de ghnáth ag ard luas . An torann de 5W % 7b 7b% 7b5% 7d % 7d agus 5W % 7b % 7b7% 7d % 7d ola táirgí beidh beagán níos lú nuair tiomáint i uirbeach limistéir % 2c agus an torann beidh beagán níos airde nuair tiomáint de ghnáth ag ard luas.
moladh
If the sound of the engine starts to become louder after replaceing the new oil, car owners don't have to worry too much. It is recommended to observe after running in for a period of time. If this situation still occurs after a period of running in, it is recommended that the car owner go the repair shop for inspection. Of course, after replaceing the new engine oil, don% 27t d'aon ghnó idirdhealú an fuaim an inneall . D'fhéadfadh sé a a síceolaíoch éifeacht a éisteacht an fuaim ag éirí níos airde.
