2. Instrument Panel Automobile instrument system is designed to know the operating conditions about the main parts, discover and correct troubles in time. There are many types of metering gauges: the fuel gauge, the coolant temperature gauge, the oil-pressure gauge, the ammeter, the tachometer, the voltmeter and so on. Modern vehicles commonly use combination instruments. Combination instruments incorporate different instrument cores, indicator lights and warning lamps into one crust.

4. Automobile Sensors There are many sensors required for a modern engine to function, the sensors used to monitor the variables do so by converting the variables' physical quantities into related electrical signals. Common measures in automobiles are temperature, pressure, flow, position, position/speed, knock and oxygen concentration

8. Dialogue Customer: Hello!. Repairman: Hi! Customer: My speedometer does not work. Repairman: When did you lubricate the speedometer-head last time? Customer: I can not remember that. About one year ago. Repairman: That is the reason Speedometers need periodic maintenance. We should lubricate the head once a year. Customer: How to do that? Repairman: Pull the cluster out, disconnect the cable, and feed modest doses of lubricant into the head. Customer: Oh, is it difficult? Repairman: No, I will get somebody to repair that at once. Customer: Ok, thank you. Repairman: Not at all.
