D. is decided by the engine speed, constant at all engine speed
答案A
fluctuate [‘flktjueit] v. 变动,上下,动摇 independent of 不依赖…的;不受…支配的
在传统系统中,喷射压力在某种程度上随主机速度 而发生波动,而在共轨柴油机中,该压力与转速无 关

  2.In common rail engines, the fuel is before is injected into the cylinders. A. stored in a common fuel line B. pumped by the injection pump C. at low pressure D. already atomized
答案 A 在共轨柴油机中,燃油在喷射入气缸前存储在公共的燃 油管路中。
fuel line 燃油管路 atomized 雾化的

  3.In a common rail engine, the fuel is injected
into cylinders . A. by injection pumps B. at a time decided by the injection pump timing C. by a signal opening the magnetic valves D. at a time decided by the cam directly
答案 C 在共轨柴油机中燃油通过一个信号打开电磁阀后喷射入气缸。
injection pump 喷射泵,注射泵 magnetic valves 电磁阀

  4. uses one or two high pressure pumps for all the cylinders with one more standby, while have a separate high-pressure pump for each cylinder. A. A common rail engine, conventional engines B. A conventional engine, common rail engines C. A marine diesel engine, most other engines D. A two-stroke engine, four-stroke engines
答案 A 共轨柴油机所有气缸使用一至两个高压泵并配有备用泵,而传统 柴油机每个气缸各自有独立的高压泵。
high pressure pump高压泵 standby备用

  5.A common rail engine has only one or two high pressure pumps in operation at the same time, and the injection into each cylinder . A. can’t be controlled very precisely B. can’t be controlled as flexibly as the separate pump system C. can be controlled as flexibly as the separate pump system D. can be controlled more precisely and flexibly
答案D 共轨柴油机在运行时同时只用一至两台高压泵,这样燃油喷 射入气缸就可进行更精确灵活的控制。

  6.The common rail engines show great advantages in combustion especially . A. at high speed and full load B. at low speed and part load C. when heavy fuel oil is used at sea D. when the ships run long distance 答案B 共轨柴油机特别是在低速和部分负荷时显示出其在燃烧 方面更大的优势

  7.To meet the market requirements, a marine diesel engine should not be of . A. big size B. fuel economy C. low speed D. high power
答案 A 为迎合市场需要,船用柴油机尺寸不应过大。
fuel economy 节油

  8.The main purpose of changing main engine to electronic controlled is not to . A. control fuel injection time more precisely B. control fuel injection rate more precisely C. meet the environmental requirements D. meet high engine speed requirements
答案D 主机采用电子控制的主要目的不是为了满足高速 运转的要求。

  9.If a cam-controlled engine has a normal injection pressure at rated speed, the injection pressure will be at slow speed. A. a little lower B. a little higher C. too low D. exactly the same 答案 A 如果凸轮控制的发动机在额定转速下喷射压力正常,那 么在低速运转时压力会略低。 cam-controlled engine凸轮控制的发动机 rated speed额定转速

  10.If a camshaft-less engine has a normal injection pressure at rated speed, the injection pressure will be at low speed. A. too low B. a little lower C. a little higher D. exactly the same
答案 D
如果无凸轮轴的发动机在额定转速下喷射压力正常,那 么在低速运转时压力不变 camshaft-less engine 无凸轮轴的发动机

  11. is not a feature of the electronic controlled engines. A. Lower fuel consumption B. Better balanced cylinder power C. A shorter overhaul period D. Less smoke emission
答案C 大修间隔时间短不是电控柴油机的特点之一。

  12.The mechanical exhaust valve operation system is replaced by in an electronic controlled ME engine. A. a system with a Hydraulic Power Supply (HPS) unit B. a system with roller guides for exhaust valves C. a system with an electronically controlled Alpha Lubricator D. a system directly powered by electric motor 答案A 在电控的船用主机中,带有液压动力单元的系统已取代 了排气阀的机械操作系统。 Hydraulic Power Supply (HPS) 液压动力单元 roller guide 滚针导轨;
Part III Translation
A. Sentences

  1. Unlike in conventional systems, the injection pressure is independent of the engine speed. Thus there is always full pressure available. 与传统的柴油机不同,(共管柴油机的)喷射压力 与转速无关。因此总是有最大压力。

  2. In conventional stroke controlled systems, which function with pilot and post-injections, there is a permanently high pressure of 1,600 bar, for example, at the needle seat near the combustion chamber. 在传统的(柱塞)行程控制的(喷射〉系统中,有喷射提 前和喷 射迟滞。比如在靠近燃烧室的针阀阀座处,总 是存在1 600 bar的高压。

  3. By means of CR injection it is possible to control combustion precisely and flexibly within the operating range of the engine. This lowers the fuel consumption. 通过共管喷射,可在发动机整个运行范围内精确灵活 地控制燃烧。这样就降低了燃油消 耗。

  4. However, a mechanical cam is fixed once made and, in spite of various mechanical and hydraulic add-on devices like VIT, etc., timing control possibilities are limited with mechanical cams. 然而机械凸轮一旦安装就固定在那儿,尽管有各种机械 和液压的外加装置,如可变喷油定时(VIT)机构等,定时 控制的可调性仍然是受机械凸轮限制的。

  5. Before engine start, the hydraulic oil pressure
used in the mechanical/hydraulic system (for controlling the actuators) is generated by electrically driven start-up pumps. After start, the engine driven pump will take over the supply. 柴油机起动前,控制执行机构的机械液压系统的液 压油由电动起动泵供给。起动之后,改由机带泵 机带泵供 机带泵 给。

  6. For the ME engines, the electronic control system has been made complete. Hence, the ME engine features fully integrated control of all functions like the governor, start and reversing, fuel, exhaust and starting valves, as well as cylinder oil feeding. ME系列柴油机的电控系统已经变得更加完善了。因 此,ME系列柴油机的特点是调速、起动、换向、供 油、排气阀和起动阀,以及气缸油的注油控制等所 有功能集为一体。
