很多車主都有這樣的體驗(yàn)，當(dāng)發(fā)動(dòng)機(jī)的轉(zhuǎn)速很高的時(shí)候，就出現(xiàn)斷油的情況。自動(dòng)變速箱維修廠家小編接下來(lái)為您講解為什么要這么做呢？廠家的設(shè)計(jì)肯定不會(huì)無(wú)的放矢，因此小編咨詢了4s店的維修師傅，現(xiàn)在把結(jié)果和廣大車主朋友分享。
Many car owners have this experience. When the engine speed is very high, there is a fuel cut-off. The small editor of the automatic transmission maintenance manufacturer will explain why you do this next? The manufacturer's design will not be aimless, so Xiaobian consulted the maintenance master of 4S store and now shares the results with the majority of car owners.
首先來(lái)看什么是發(fā)動(dòng)機(jī)斷油。發(fā)動(dòng)機(jī)斷油是指發(fā)動(dòng)機(jī)在轉(zhuǎn)速達(dá)到一定高度是，如8000轉(zhuǎn)/分，行車電腦會(huì)自動(dòng)停止對(duì)發(fā)動(dòng)機(jī)供油，令發(fā)動(dòng)機(jī)轉(zhuǎn)速不能超過(guò)限值，這是廠家出于保護(hù)發(fā)動(dòng)機(jī)的目的而特別設(shè)計(jì)的。
First, let's look at what is engine oil cut-off. Engine oil cut-off means that when the engine speed reaches a certain height, such as 8000 rpm, the trip computer will automatically stop supplying oil to the engine, so that the engine speed can not exceed the limit, which is specially designed by the manufacturer for the purpose of protecting the engine.
普通發(fā)動(dòng)機(jī)設(shè)計(jì)轉(zhuǎn)速通常不會(huì)超過(guò)8000轉(zhuǎn)/分，但是競(jìng)技用發(fā)動(dòng)機(jī)，如F1所用的發(fā)動(dòng)機(jī)，通常換擋轉(zhuǎn)速都會(huì)在18000轉(zhuǎn)/分以上。然后怎么提前預(yù)知要出現(xiàn)發(fā)動(dòng)機(jī)斷油呢?其實(shí)在轉(zhuǎn)速表上一般都用紅區(qū)標(biāo)示發(fā)動(dòng)機(jī)的危險(xiǎn)轉(zhuǎn)速，當(dāng)指針進(jìn)入紅區(qū)后，發(fā)動(dòng)機(jī)一般都會(huì)停止燃油噴射。如果是自動(dòng)擋車型，則會(huì)自動(dòng)換擋以降低發(fā)動(dòng)機(jī)轉(zhuǎn)速。
The design speed of ordinary engine usually does not exceed 8000 rpm, but the shift speed of competitive engine, such as the engine used in F1, is usually more than 18000 rpm. Then how can we predict in advance that there will be an engine fuel cut-off? In fact, the red zone is generally used to indicate the dangerous speed of the engine on the tachometer. When the pointer enters the red zone, the engine will generally stop fuel injection. In the case of automatic models, it will shift automatically to reduce the engine speed.
所以，出現(xiàn)發(fā)動(dòng)機(jī)斷油的時(shí)候不要誤以為是發(fā)動(dòng)機(jī)出問(wèn)題了。另外，為了自己的愛(ài)車著想，自動(dòng)變速箱維修廠家小編建議不要使發(fā)動(dòng)機(jī)轉(zhuǎn)速提的太高。
Therefore, when the engine is out of oil, don't mistakenly think that there is something wrong with the engine. In addition, for the sake of your car, the small editor of the automatic transmission maintenance manufacturer recommends not to raise the engine speed too high.
