【文章內容簡介】 antity 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。the injection pressure at pressure at present is 160 MPa。in future this will rise to 180 monrail system allows a future reduction in exhaustgas emissions by introducing preinjection events or multiple injection events and also attenuating bustion noise injection events of up to five per injection cycle can be generated by triggering the highly rapidaction switching valve several nozzleneedle closing action is hydraulically assisted to ensure that the end of injection is rapid.(5)Control and engine control unit detects the acceleratorpedal position and the current operating states of the engine and vehicle by means of data collected includes:① Crankshaft speed and angle。② Fuelrail pressure。③ Chargeair pressure:④ Intake air, coolant temperature, and fuel temperature: ⑤ Airmass intake: ⑥ Road speed, electronic control unit evaluates the input sync with bustion, it calculates the triggering signals for the pressurecontrol valve or the metering unit, the injectors, and the other actuators( EGR valve, exhaustgas turbocharger actuators, etc.).The injector switching times, which need to be short, are achievable using the optimized highpressure switching valves and a special control angle/time system pares 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 addition, EDC offers the potential for additional functions that can improve engine response and basic functions involve the precise control of dieselfuel injection timing and fuel quantity at the reference this way, they ensure that the diesel engine has low consumption and smooth running openand closeloop control functions perform the tasks of reducing exhaustgas emissions and fuel consumption, or providing added safely and examples are:① Control of exhaustgas recirculation。② Boostpressure control。③ Cruise control。④ Electronic immobilizer, etc.(6)Control Unit 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 are coupled within the “ master/slave ” network via an internal, highspeed CAN a result, there is also a high microcontroller processing capacity functions are permanently allocated to a specific control unit( control).Other can be dynamically allocated to one or many of the control units as situation demand( detect sensor signals).第二篇：中英文對照A《美國口語慣用法例句集粹》ＡA(Page 14)1)2)3)4)5)6)7)I39。d like to know what this is all 。How about a fish sandwich? 來一塊魚肉三明治怎么樣？What about me? 我怎么樣？I39。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。s this all about? 這到底是怎么回事？It39。s about time you showed up!差不多是你該露面的時候了。1)2)Above all, I want everything ：我要一切保持安定。Tom thinks he39。s above hard 。1)2)3)4)5)6)Would you please act out what happened?
