The vehicle information displaying system is one of the important systems of the automobile. The driver can know whether the cars, especially the various operating parameters of the engine are normal or not in order to take timely measures to prevent the occurrence of physical and mechanical accidents.
①The vehicle information displaying system 汽车信息显示系统
②operating parameters ['ɒpəreɪtɪŋ] [pə'ræmɪtə] 工作参数
③take timely measures to prevent the occurrence of …
measure ['meʒə]n. 措施、测量
④ occurrence [ə'kʌr(ə)ns] 发生
④ physical ['fɪzɪk(ə)l] adj.物理的，身体的
⑤ mechanical [mɪ'kænɪk(ə)l] adj. 机械的，力学的
汽车信息显示系统是汽车系统中一个重要的系统。司机能够了解汽车，特别是发动机的各种工作参数是否正常，以便适时采取措施来防止人身和机械故障的发生。
The instrumentations in different vehicle instrument panels are not the same. The instruments commonly used include speedometer, engine tachometer, oil pressure gauge, water temperature gauge, fuel gauge, ammeter, etc. Changes of the monitored object’s status are directly shown in most instruments through the sensors.
① instrumentation [,ɪnstrʊmen'teɪʃ(ə)n] 仪器仪表，测量设备
② instrument panels 仪表板 panel ['pæn(ə)l]面板、仪表板
③ speedometer [spiː'dɒmɪtə] 车速表、 速度表
④ engine tachometer [tæ'kɒmɪtə] 发动机转速表
⑤ oil pressure gauge 油压表 gauge [geɪdʒ] 计量计
⑥ water temperature gauge ['temp(ə)rətʃə] 水温表
⑦ fuel gauge 燃油表
⑧ ammeter ['æmɪtə] 安培表
不同汽车仪表板的仪表不尽相同，常用的仪表有车速表、发动机转速表、机油压力表、水温表、燃油表、电流表等。 大部分仪表通过传感装置获得被监测对象的状态变化而直接表述出来。
1. Speedometers（车速表）
The speedometer shows your speed in kilometers per hour (km/h) and/or miles per hour (mph) depending on type.
速度表根据汽车类型显示每小时行驶的千米数或每小时的英里数。
2. Tachometer （发动机）转速表
The tachometer shows the engine speed in revolutions per minute (rpm). To protect the engine from damage，never drive with the tachometer needle in the red zone.
① revolution [revə'luːʃ(ə)n] 转速、旋转、循环、革命
② to protect…from… 防止…受损
③ never drive with the tachometer needle in the red zone.地区、区域
转速表显示发动机每分钟的转速。驾驶时，不要使转速表的指针指向红区， 以免发动机受到损伤。
3. Fuel Gauge 燃油表
The fuel gauge displays approximately how much fuel you have in the fuel tank.
Note：For proper fuel gauge operation, the ignition switch must be in the OFF position before you add fuel to the fuel tank.
The fuel gauge indicator may vary slightly while the vehicle is in motion. This is the result of fuel movement within the tank. An accurate reading may be obtained with the vehicle on the smooth, level ground.
① approximately [ə'prɒksɪmətlɪ] adv. 大约、近似
② fuel tank 燃油箱tank 槽，水槽、坦克
③ ignition switch 点火开关
④ vary slightly 轻微变化 vary ['veərɪ] vt.改变、变化
⑤ accurate ['ækjʊrət] 精确的，精准的
⑥ obtain [əb'teɪn] 获得
燃油表可大约显示油箱中现存的油量。
注意:加油前点火开关须在“关”（OFF)位置，燃油表才可正常显示。
行车时 燃油表有少许摆动是由于油箱内燃油波动的缘故。当汽车在平坦路面上行驶时， 油量读数较精确。
4. Water Temperature Gauge 水温表
This shows the temperature of the engine’s coolant. During normal operation, the pointer should rise from the bottom blue mark to about the middle of the gauge. In severe driving conditions, such as very hot weather or a long period of uphill driving the pointer may rise to the upper white mark. If it reaches the red (Hot) mark, the engine is overheated and may be damaged.
If your engine overheats ：
① Pull off the road as soon as it is safely possible.
② Turn off the engine.
③ Let the engine cool.
④ Check the coolant level following the instructions on（有关于） checking and adding coolant to your engine, and see the Engine Coolant in the Index.
Inspect the Water Temperature Receiver Gauge Warning Light
① following the instructions 按照说明
这个表显示发动机冷却剂的温度。正常驾驶时，表的长针应从表中蓝标记 下端指到大约中间的位置上。在恶劣的驾驶条件，例如非常炎热或长时间爬坡过 程中，表的指针会指向上面的白范围内。如果指针指向红（热）范围内，则发 动机已过热，可能会损坏发动机。
若发动机过热：
① 尽快安全地停在路边。
② 关闭发动机
③ 让发动机冷却。
根据有关检查及加注发动机冷却剂说明,检查冷却剂液面
检查水温表警告灯
5、Engine Oil Pressure Warning Light
This light indicates the engine oil pressure, not the oil level. However, if your engine oil level is low，it could affect the oil pressure. The light should come on every time your ignition key is turned to ON or START and go out when the engine starts. If the light stays on or turns on while the engine is running, you have lost oil pressure and continued operation will cause severe engine damage.
① indicate ['ɪnd汽车仪表识别ɪkeɪt] vt. 表明，指示
② go out 熄灭；turn on 开启
If you lose oil pressure ：
Pull off the road as soon as it is safely possible.
Shut off the engine immediately. If you do not stop the engine as soon as possible, severe engine damage could occur.
If the level is low, add only as much oil as necessary before you start the engine again. Do not overfill. Do not operate the engine again, if the light is on, regardless of the oil level.
油压警告灯显示发动机油压，而不是机油液位，然而若发动机机油液位低，就会影响油压。每次点火钥匙扭至“ ON”或“ START”位置时,油压警告灯亮，发动机启动时应该熄灭。如果警告灯持续亮或发动机运转时仍亮着，则表明汽车油压过 低，如果继续工作将会给发动机带来严重的损害。
如果油压过低：你应该
1、尽快安全地停在路边。
2、立即关闭发动机。如果未尽快停止发动机，则发动机可能会发生严重 损伤。
3、检查发动机机油液面。如果液面过低,在再次启动发动机之前，请按需求添加机油。不要溢出。 油压警告灯亮时,无论液面怎样,都不要再次启动发动机。
