【正文】 ure that the pump delivers exactly the right quantity of fuel rail in order to maintain the injection pressure required by the a fault situation, the pressurerelief valve prevents rail pressure from exceeding a control on the suction side reduces the quantity of fuel under high pressure and lowers the power input of the has a positive impact on fuel the same time, the temperature of the fuel flowing back to the fuel tank is reduced in contrast to the control method on the highpressure twoactuator system is also a way of controlling rail pressure, which bines pressure control on the suction side via the metering unit and control on the highpressure side via the pressurecontrol valve, thus marrying the advantages of highpressureside control and suctionside fueldelivery control.(3)Fuel injectors spray fuel directly into the engine’s bustion are supplied by short highpressure fuel lines connected to the fuel engine control unit controls the switching valve integrated in the injector to open and closethe injector injector opening times and system pressure determine the quantity of fuel a constant pressure, the fuel quantity delivered is proportional to the switching time of the solenoid is, therefore, independent of engine or pump speed(timebased fuel injection).(4)Potential Hydraulic the functions of pressure generation and fuel injection opens up future degrees of freedom in the bustion process pared with conventional fuelinjection systems。由于發(fā)動機(jī)控制單元通常最多有8個噴油器輸出口，所以超過八缸的發(fā)動機(jī)需要兩個控制單元。其基本功能包括對柴油燃油噴射正時的精確控制，和在給定壓力下對油量的控制。噴油器的開關(guān)時間應(yīng)很短，采用優(yōu)化的高壓開關(guān)閥和專業(yè)的控制系統(tǒng)即可實(shí)現(xiàn)。(5)控制和調(diào)節(jié)發(fā)動機(jī)的控制單元通過傳感器檢測加速踏板的位置以及發(fā)動機(jī)和車輛的當(dāng)前工況。目前最高燃油壓力為1600巴，將來會達(dá)到1800巴。噴油器的開啟時間和系統(tǒng)油壓決定了燃油供給量。雙執(zhí)行器系統(tǒng)也是一種控制軌道壓力的方式，它通過計(jì)算單元對壓力進(jìn)行控制，并且通過壓力控制閥對高壓端進(jìn)行控制，因此同時具備高壓側(cè)控制與進(jìn)口端燃料供給控制的優(yōu)勢。發(fā)生故障時，壓力安全閥防止油軌壓力超過最大值。在第一批共軌系統(tǒng)中采用了對高壓側(cè)的控制。(2)壓力控制所應(yīng)用的壓力控制方法主要取決于系統(tǒng)。由發(fā)動機(jī)驅(qū)動的連續(xù)運(yùn)轉(zhuǎn)的高壓泵提供所需噴油的壓力。EDC控制每個組件。它們擁有一個可以快速開關(guān)噴嘴的執(zhí)行閥(電磁閥或壓電觸發(fā)器)，這就允許對每個氣缸的噴射進(jìn)行控制。共軌系統(tǒng)包括以下幾個主要的部分： ①低壓部分，包含燃油共軌系統(tǒng)組件。更高的壓力、更快的開關(guān)時間，以及根據(jù)發(fā)動機(jī)工況修訂的可變的流量速率曲線，已經(jīng)使得柴油發(fā)動機(jī)具有良好的經(jīng)濟(jì)性、低污染、高動力性，因此柴油發(fā)動機(jī)甚至進(jìn)入了豪華高性能轎車領(lǐng)域。Dave and Kathy are going to steal away on 去。d do away with these plicated tax 。Kent describes himself as just an average 。Police are baffled as to the whereabouts of the 挫。m going ，我準(zhǔn)備回家。1)2)Coach Johnson has been around for 30 。t have to twist my arm to get me to go with 。1)2)3)4)5)Have you ever been to the Big Apple? 你去過紐約嗎？Do I sense an apple of discord between you two? 你問我有沒有感覺出你們兩人之間的不和，是嗎？Heather is the apple of my 。t go on the American 。Some foreigners bee Americanized while living in the 。t you just leave well enough alone? 你不能少管一些閑事嗎？1)2)You knew all along what was going 。1)Working on cars isn39。Let39。d just as soon not ，我就不想去了。We knew it was all over when we saw the building ，我們知道一切全完了。d say it39。t be going after 。I hope there39。Your sister is such an 。s wrong, but can feel it in the ，但我能隱隱約約感覺到。This is a “ing of age” 。I see your point, but don39。1)2)Our opponents have a height advantage on 。re going to bring action against our 。We need to get our act together and e to see 。Tom thinks he39。m not about to go in that old ！Yes I remember that about it? 是的，我記得那個晚上，那又怎樣？What39。第一篇：尿常規(guī)中英文對照糖（GLU）Negatlve尿膽紅素（BIL）Negatlve酮體（KET）Negatlve比重（SG）隱血（BLD、ERY）Negatlve 酸堿度（pH） 蛋白質(zhì)（PRO）Negatlv
