第五篇:中英文對照
共軌技術
隨著人們對低油耗、低廢氣排放、發(fā)動機低噪聲的需求越來越大,對發(fā)動機和燃油噴射系統(tǒng)的要求也越來也高。對柴油發(fā)動機燃油噴射系統(tǒng)提出的要求也在不斷增加。更高的壓力、更快的開關時間,以及根據(jù)發(fā)動機工況修訂的可變的流量速率曲線,已經(jīng)使得柴油發(fā)動機具有良好的經(jīng)濟性、低污染、高動力性,因此柴油發(fā)動機甚至進入了豪華高性能轎車領域。達到這些需求的前提是擁有一個可以精確霧化燃油并具有高噴油壓力的燃油噴射系統(tǒng)。同時,噴油量必須精確計算,燃油流量速率曲線必須有精確的計算模型,預噴射和二次噴射必須能夠完成。一個可以達到以上需求的系統(tǒng)即共軌燃油噴射系統(tǒng)。
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。
②高壓系統(tǒng),包含高壓泵、油軌、噴油器和高壓油管等組件。
電控柴油機系統(tǒng)EDC主要由系統(tǒng)模塊,如傳感器、電子控制單元和執(zhí)行機構組成。共軌系統(tǒng)的主要部分即噴油器。它們擁有一個可以快速開關噴嘴的執(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行控制。
所有的噴油器都由一個共同的油軌提供燃油,這就是“共軌”的由來。在共軌燃油噴射系統(tǒng)中,燃油噴射和壓力的產(chǎn)生是分開的。噴油壓力的產(chǎn)生與發(fā)動機轉速和噴油量無關。EDC控制每個組件。
(1)壓力產(chǎn)生。
燃油噴射和壓力的產(chǎn)生是通過蓄能器分離開來。將具有壓力的燃油提供給為噴射做好準備的共軌系統(tǒng)的蓄能器。
由發(fā)動機驅(qū)動的連續(xù)運轉的高壓泵提供所需噴油的壓力。無論發(fā)動機的轉速高低,還是燃油噴射量的多少,油軌中的壓力均維持在一定值。由于幾乎一致的噴油方式,高壓泵的設計可以小的多,而且它的驅(qū)動轉矩可以比傳統(tǒng)燃油噴射系統(tǒng)低,這源于高壓泵的負載很小。
高壓泵是徑向活塞泵,在商用車上有時會使用內(nèi)嵌式噴油泵。(2)壓力控制
所應用的壓力控制方法主要取決于系統(tǒng)。
一種控制油軌壓力的方式是通過一個壓力控制閥對高壓側進行控制。不需噴射的燃油通過壓力控制閥流回到低壓回路。這種控制回路允許油軌壓力對不同工況(如負載變化時)迅速做出反應。
在第一批共軌系統(tǒng)中采用了對高壓側的控制。壓力控制閥安裝在燃油軌道上更可取,但是在一些應用中,它被直接安裝在高壓泵中。
另一種控制軌道壓力的方式是進口端控制燃油供給。安裝在高壓泵的法蘭上的計量單元保證了泵提供給油軌精確的燃油量,以維持系統(tǒng)所需要的噴油壓力。
發(fā)生故障時,壓力安全閥防止油軌壓力超過最大值。
在進口端對燃油供給的控制減少了高壓燃油的用量,降低了泵的輸入功率。這對燃油消耗起到積極的作用。同時,流回油箱的燃油溫度與傳統(tǒng)高壓側控制的方法相比得到了降低。
雙執(zhí)行器系統(tǒng)也是一種控制軌道壓力的方式,它通過計算單元對壓力進行控制,并且通過壓力控制閥對高壓端進行控制,因此同時具備高壓側控制與進口端燃料供給控制的優(yōu)勢。
(3)燃油噴射
噴油器直接將燃料噴到發(fā)動機的燃燒室。它們由與燃油軌道直接相連的短高壓油軌提供燃油。發(fā)動機的控制單元通過與噴油器結合在一起的控制閥的開閉控制噴油嘴的開關。
噴油器的開啟時間和系統(tǒng)油壓決定了燃油供給量。在恒壓狀態(tài)下,燃油供給量與電磁閥的開啟時間成正比,因此與發(fā)動機或油泵的轉速(以時間為計量的燃油噴射)無關。
(4)液壓輔助動力
與傳統(tǒng)燃油噴射系統(tǒng)相比,將壓力的產(chǎn)生與燃油的噴射分離開來,有利于燃燒室的充分燃燒。燃油噴射壓力在系統(tǒng)中基本可以自主選擇。目前最高燃油壓力為1600巴,將來會達到1800巴。
共軌系統(tǒng)通過引入預噴射或多次噴射可以進一步減少廢氣排放,也能明顯降低燃燒噪聲。通過多次觸發(fā)高速轉換閥的開閉可以在每個噴射周期內(nèi)實現(xiàn)多達5次的噴射。噴油針閥的開閉動作是液壓輔助元件助力的,以保證噴射結束的快速性。
(5)控制和調(diào)節(jié)
發(fā)動機的控制單元通過傳感器檢測加速踏板的位置以及發(fā)動機和車輛的當前工況。采集到的數(shù)據(jù)包括:
① 曲軸轉速和轉角; ② 燃油軌道的壓力; ③ 進氣壓力;
④ 進氣溫度、冷卻液溫度和燃油溫度; ⑤ 進氣量; ⑥ 車速等。
電控單元處理輸入信號。與燃燒同步,電控單元計算施加給壓力控制閥或計算模塊、噴油器和其他執(zhí)行機構(如EGR閥,廢氣渦輪增壓器)的觸發(fā)信號。
噴油器的開關時間應很短,采用優(yōu)化的高壓開關閥和專業(yè)的控制系統(tǒng)即可實現(xiàn)。
根據(jù)曲軸和凸輪軸傳感器的數(shù)據(jù),對照發(fā)動機狀態(tài)(時間控制),角度/時間系統(tǒng)調(diào)節(jié)噴油正時。電控柴油機系統(tǒng)(EDC)可以實現(xiàn)對燃油噴射量的精確計算。此外,EDC還擁有額外的功能以進一步提高發(fā)動機的響應特性和便利性。
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。這樣,它們就保證了柴油發(fā)動機具有能耗低、運行平穩(wěn)的特點。
其他開環(huán)和閉環(huán)控制功能用于減少廢氣排放和燃油消耗,或提供附加的可靠性和便利性,具體例子有:
① 廢氣在循環(huán)控制; ② 增壓控制; ③ 巡航控制;
④ 電子防盜控制系統(tǒng)等。(6)控制單元結構。
由于發(fā)動機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)動機需要兩個控制單元。它們通過內(nèi)置高速CAN網(wǎng)絡的“主/從”接口進行連接,因此也擁有較高的微控制器處理能力。一些功能被 分配給某個特定的控制單元(如燃料平衡控制),其功能根據(jù)需求情況(如檢測傳感器信號)可以動態(tài)地分配給一個或多個控制單元。
The Common Rail Calls for lower fuel consumption, reduced exhaust-gas emission, and quiet engines are making greater demands on the engine and fuel-injection system.The demands placed on diesel-engine fuel-injection systems are continuously increasing.Higher pressures, faster switching times, and a variable rate-of-discharge curve modified to the engine operating state have made the diesel engine economical, clean, and powerful.As a result, diesel engines have even entered the realm of luxury-performance sedans.These demands can only be met by a fuel-injection pressure.At the same time the injected fuel quantity must be very precisely metered, and the rate-of-discharge curve must have an exact shape, and pre-injection and secondary injection must be performable.A system that meets these demands is the common-rail fuel-injection system.The main advantage of the common-rail system is its ability to vary injection pressure and timing over a broad scale.This was achieved by separating pressure generation(in the high-pressure pump)from the fuel-injection system(injection).The rail here acts as a pressure accumulator.Principle of the Common Rail The common-rail system consists of the following main component groups: ① The low-pressure stage, comprising the fuel-supply system components;② The high-pressure system, comprising components such as the high-pressure pump, fuel-rail, injector, and high-pressure fuel lines.The electronic diesel control(EDC), consisting of system modules, such as sensors, the electronic control unit, and actuators.The key components of the common-rail system are the injectors.They are fitted with a rapid-action valve(solenoid valve or piezo-triggered actuator)which opens and closes the nozzle.This permits control of the injection process for each cylinder.All the injectors are fed by a common fuel rail, this being the origin of the term “common rail”.In the common-rail fuel-injection system, the function of pressure generation and fuel injection are separate.The injection pressure is generated independent of the engine speed and the injected fuel quantity.The electronic diesel control(EDC)controls each of the components.(1)Pressure Generation.Pressure generation and fuel injection are separated by means of an accumulator volume.Fuel under pressure is supplied to the accumulator volume of the common
rail ready for injection.A continuously operating high-pressure pump driven by the engine produces the desired injection pressure.Pressure in the fuel rail is maintained irrespective of engine speed or injected fuel quantity.Owing to the almost uniform injection pattern, the high-pressure pump design can be much smaller and its drive-system torque can be lower than conventional fuel-injection systems.This results in a much lower load on the pump drive.The high-pressure pump is a radial-piston pump.On commercial vehicles, an in-line fuel-injection pump is sometimes fitted.(2)Pressure Control The pressure control method applied is largely dependent on the system.One way of controlling rail pressure is to control the high-pressure side by a pressure-control valve.Fuel not required for injection flows back to the low-pressure circuit via the pressure-control valve.This type of control loop allows rail pressure to react rapidly to changes in operating point(e.g.in the event of load changes).Control on the high-pressure side was adopted on the first common-rail systems.The pressure-control valve is mounted preferably on the fuel rail.In some applications, however, it is mounted directly on the high-pressure pump.Another way of controlling rail pressure is to control fuel delivery on the suction side.The metering unit flanged on the high-pressure pump makes sure that the pump delivers exactly the right quantity of fuel rail in order to maintain the injection pressure required by the system.In a fault situation, the pressure-relief valve prevents rail pressure from exceeding a maximum.Fuel-delivery control on the suction side reduces the quantity of fuel under high pressure and lowers the power input of the pump.This has a positive impact on fuel consumption.At the same time, the temperature of the fuel flowing back to the fuel tank is reduced in contrast to the control method on the high-pressure side.The two-actuator system is also a way of controlling rail pressure, which combines pressure control on the suction side via the metering unit and control on the high-pressure side via the pressure-control valve, thus marrying the advantages of high-pressure-side control and suction-side fuel-delivery control.(3)Fuel Injection.The injectors spray fuel directly into the engine’s combustion chambers.They are supplied by short high-pressure fuel lines connected to the fuel rail.The engine control unit controls the switching valve integrated in the injector to open and close
the injector nozzle.The injector opening times and system pressure determine the quantity of fuel delivered.At a constant pressure, the fuel quantity delivered is proportional to the switching time of the solenoid valve.This is, therefore, independent of engine or pump speed(time-based fuel injection).(4)Potential Hydraulic Power.Separating the functions of pressure generation and fuel injection opens up future degrees of freedom in the combustion process compared with conventional fuel-injection systems;the injection pressure at pressure at present is 160 MPa;in future this will rise to 180 MPa.The common-rail system allows a future reduction in exhaust-gas emissions by introducing pre-injection events or multiple injection events and also attenuating combustion noise significantly.Multiple injection events of up to five per injection cycle can be generated by triggering the highly rapid-action switching valve several times.The nozzle-needle closing action is hydraulically assisted to ensure that the end of injection is rapid.(5)Control and Regulation.The engine control unit detects the accelerator-pedal position and the current operating states of the engine and vehicle by means of sensors.The data collected includes:
① Crankshaft speed and angle;② Fuel-rail pressure;③ Charge-air pressure:
④ Intake air, coolant temperature, and fuel temperature: ⑤ Air-mass intake: ⑥ Road speed, etc.The electronic control unit evaluates the input signals.In sync with combustion, it calculates the triggering signals for the pressure-control valve or the metering unit, the injectors, and the other actuators(e.g.the EGR valve, exhaust-gas turbocharger actuators, etc.).The injector switching times, which need to be short, are achievable using the optimized high-pressure switching valves and a special control system.The angle/time system compares injection timing, based on data from the crankshaft and camshaft sensors, with the engine state(time control).The electronic diesel control(EDC)permits a precise metering of the injected fuel quantity.In
addition, EDC offers the potential for additional functions that can improve engine response and convenience.The basic functions involve the precise control of diesel-fuel injection timing and fuel quantity at the reference pressure.In this way, they ensure that the diesel engine has low consumption and smooth running characteristics.Additional open-and close-loop control functions perform the tasks of reducing exhaust-gas emissions and fuel consumption, or providing added safely and convenience.Some examples are:
① Control of exhaust-gas recirculation;② Boost-pressure control;③ Cruise control;
④ Electronic immobilizer, etc.(6)Control Unit Configuration.As the engine control unit normally has a maximum of only eight output stages for the injectors, engines with more than eight cylinders are fitted with two engine control units.They are coupled within the “ master/slave ” network via an internal, high-speed CAN interface.As a result, there is also a high microcontroller processing capacity available.Some functions are permanently allocated to a specific control unit(e.g.fuel-balancing control).Other can be dynamically allocated to one or many of the control units as situation demand(e.g.to detect sensor signals).
