The lighting effect of automobile spark plug is mixed gas. The engine can start to work, which is equivalent to the "heart" of many important engines. After the spark plug needs to be replaced due to wear and tear for a period of time, some owners of Jinan Audi automobile maintenance company change to fuel. After they want to know the reason of a new spark plug oil, the new spark plug needs to be run in. See the figure below.

　　更換火花塞后耗油的原因

　　Causes of fuel consumption after spark plug replacement主人覺(jué)得當(dāng)他們改變一個(gè)新的火花塞燃料消耗增加,因?yàn)楝F(xiàn)在發(fā)動(dòng)機(jī)是通過(guò)計(jì)算機(jī)來(lái)控制噴油量和點(diǎn)火,由于計(jì)算機(jī)控制單元是適應(yīng)舊的火花塞的工作狀態(tài),所以在更換新的火花塞,電腦會(huì)根據(jù)新的火花塞,調(diào)整從而使所有者燃料消耗增加。

　　The owner thinks that when they change a new spark plug, the fuel consumption increases, because the engine now controls the fuel injection and ignition through the computer. Because the computer control unit adapts to the working state of the old spark plug, when replacing the new spark plug, the computer will adjust according to the new spark plug, thus increasing the owner's fuel consumption.

　　此外,燃料消耗增加火花塞的更換后也可以更換火花塞的所有者模型是錯(cuò)誤的,火花塞間隙尺寸的不同,使點(diǎn)火的成功率降低,并導(dǎo)致油耗的增加。或火花塞更換不緊，氣缸內(nèi)高壓氣體泄漏，壓力降低，因而也會(huì)出現(xiàn)怠速不穩(wěn)的現(xiàn)象。

　　In addition, the owner model of spark plug can also be changed after the replacement of spark plug due to the increase of fuel consumption. The difference of gap size of spark plug reduces the success rate of ignition and leads to the increase of fuel consumption. Or the spark plug is not replaced tightly, the high-pressure gas in the cylinder leaks and the pressure is reduced, so the idle speed will be unstable.

　　是否需要安裝新的火花塞

　　Do you need to install a new spark plug

　　一般情況下，如果業(yè)主更換原廠的同類(lèi)型火花塞不需要運(yùn)行一段時(shí)間，電腦會(huì)自動(dòng)適應(yīng)以匹配新的火花塞。但是如果主人更換火花塞，那就是不同的材料需要一段磨合時(shí)間，例如把銥火花塞換成鉑金火花塞，那么電腦需要學(xué)會(huì)適應(yīng)，調(diào)整參數(shù)。

　　Generally, if the owner does not need to run the same type of spark plug for some time, the computer will automatically adapt to match the new spark plug. But if the owner changes the spark plug, it is a period of running in time for different materials, such as replacing iridium spark plug with platinum spark plug, then the computer needs to learn to adapt and adjust the parameters.
