汽車噴油嘴的那些事!

來源:http://www.nhakhoathuduc.net/ 日期:2021-10-02 發(fā)布人:admin
噴油嘴本身是一個(gè)常閉閥(常閉閥的意思是當(dāng)沒有輸入控制訊號(hào)時(shí),閥門一直處于關(guān)閉狀態(tài)),由一個(gè)閥針上下運(yùn)動(dòng)來控制閥的開閉。當(dāng)電腦下達(dá)噴油指令時(shí),其電壓訊號(hào)會(huì)使電流流經(jīng)噴油嘴內(nèi)的線圈,產(chǎn)生磁場(chǎng)來把閥針吸起,讓閥門開啟好使油料能自噴油孔噴出。噴射供油的優(yōu)點(diǎn)就是燃油供給之控制十分精 確,讓引擎在任何狀態(tài)下都能有正確的空燃比,不僅讓引擎保持運(yùn)轉(zhuǎn)順暢,其廢氣也能合乎環(huán)保法規(guī)的規(guī)范。
The fuel injection nozzle itself is a normally closed valve (normally closed valve means that the valve is always closed when no control signal is input), and a valve needle moves up and down to control the opening and closing of the valve. When the computer gives the fuel injection command, its voltage signal will make the current flow through the coil in the fuel injection nozzle, generate a magnetic field to suck up the valve needle and open the valve so that the oil can be ejected from the fuel injection hole. The advantage of fuel injection is that the control of fuel supply is very accurate, so that the engine can have the correct air-fuel ratio in any state, not only keep the engine running smoothly, but also its exhaust gas can meet the specifications of environmental protection regulations.

噴油嘴是發(fā)動(dòng)機(jī)的重要部分,它的工作好壞將嚴(yán)重的影響發(fā)動(dòng)機(jī)的性能。噴油嘴堵塞會(huì)嚴(yán)重影響汽車性能。
Fuel injection nozzle is an important part of the engine. Its work will seriously affect the performance of the engine. Fuel injection nozzle blockage will seriously affect vehicle performance.
堵塞的原因:1、由于發(fā)動(dòng)機(jī)內(nèi)積炭沉積。2、由于燃油中的雜質(zhì)。
Causes of blockage: 1. Due to carbon deposition in the engine. 2. Due to impurities in the fuel.
噴油嘴的工作好壞,對(duì)每臺(tái)發(fā)動(dòng)機(jī)的功率發(fā)揮起著根本性作用。由于燃油不佳導(dǎo)致噴油嘴工作不靈,使缸內(nèi)積炭嚴(yán)重;缸筒、活塞環(huán)加速磨損,造成怠速不穩(wěn),油耗上升,加速無(wú)力,起動(dòng)困難及排放超標(biāo),嚴(yán)重的會(huì)徹 底堵塞噴油嘴,損壞發(fā)動(dòng)機(jī)。因此,要定時(shí)清洗噴油嘴。
The work of fuel injection nozzle plays a fundamental role in the power of each engine. Poor fuel causes the fuel injection nozzle to work improperly, resulting in serious carbon deposition in the cylinder; The accelerated wear of cylinder barrel and piston ring will cause unstable idle speed, increased fuel consumption, weak acceleration, difficult starting and excessive emission. In serious cases, the fuel injection nozzle will be completely blocked and the engine will be damaged. Therefore, clean the fuel injection nozzle regularly.
在日常行駛中,應(yīng)該經(jīng)常跑一跑高速,這樣可以減少積炭行成的可能性。如果長(zhǎng)期不清洗噴油嘴,噴油嘴會(huì)堵塞而且會(huì)越來越嚴(yán)重,從而引起發(fā)動(dòng)機(jī)噴油不暢,噴油角度和霧化不好,導(dǎo)致發(fā)動(dòng)機(jī)怠速,加速或全負(fù)荷工況時(shí)工作不好,使得發(fā)動(dòng)機(jī)功率下降,油耗上升,排放污染增加,甚至使發(fā)動(dòng)機(jī)無(wú)法工作。所以,車主朋友們一定要定期清洗噴油嘴,以確保其正常工作。
In daily driving, you should often run at a high speed, which can reduce the possibility of carbon deposition. If the fuel injection nozzle is not cleaned for a long time, the fuel injection nozzle will be blocked and become more and more serious, resulting in poor fuel injection, poor fuel injection angle and atomization of the engine, resulting in poor operation of the engine under idle speed, acceleration or full load conditions, reducing engine power, increasing fuel consumption, increasing emission pollution, and even making the engine unable to work. Therefore, car owners and friends must clean the fuel injection nozzle regularly to ensure its normal operation.
車主朋友們,清洗噴油嘴不代表經(jīng)常清洗就好。因?yàn)閲娪妥毂旧碓诎l(fā)動(dòng)機(jī)里邊,經(jīng)常拆裝會(huì)磨損相關(guān)部件,甚至?xí)鼓z圈之類的易損件壞掉,所以我們要按規(guī)定(建議4-6萬(wàn)公里,或是用電腦檢測(cè)有故障時(shí))清洗。清洗時(shí)一定要到正規(guī)修車店清洗。
Owners friends, cleaning the fuel injection nozzle does not mean that it is good to clean it often. Because the fuel injection nozzle itself is inside the engine, frequent disassembly and assembly will wear relevant parts and even damage vulnerable parts such as rubber rings, so we should clean it according to the regulations (it is recommended to drive 40000-60000 kilometers, or when there is a fault detected by computer). When cleaning, be sure to go to a regular garage for cleaning.
