P89 Answer: Vehicle formation needs to know driving skills, driving experience, safe driving kilometers, etc. Drivers who participate in transportation tasks are grouped according to their driving level. 1. When vehicles are driving in formation, the first car in the team is extremely important. The driver of the first car in the team requires a strong sense of responsibility and rich driving experience. During driving, he can drive at a good speed specified in advance, pay attention to the situation of other vehicles, maintain a normal distance between vehicles, and adjust the speed according to the driving situation. 2. When vehicles are driving in formation, the last car in the team is very important. Drivers should be experienced, responsible, calm and able to follow the car. 3. Vehicle grouping should be based on the number of vehicles. When the number of vehicles is less than 10, the sequence should be compiled, and drivers with weak driving skills should be arranged near the first car as far as possible. When the number of vehicles is greater than 10, it can be divided into several groups less than 10 according to the number of vehicles, and each group is responsible by a special person. 43.

Discussion on matters needing attention in maintenance of fuel injection device. P 137 A: 1。 The maintenance of the electronically controlled injector engine itself is the same as that of ordinary gasoline vehicles, and it should be carried out according to the regulations. Therefore, when an engine or a car breaks down, it is first necessary to find out whether the engine has a mechanical failure or the car itself has a mechanical failure. If there is no mechanical failure, you can check the electronic control system. 2. When checking the electronic control system, first check the fault code displayed by the alarm lamp with the self-checking system, and then judge the possible parts and properties according to the fault code. 3. Before the specific inspection of electronic systems or components, the battery grounding wire should be removed first. However, after the battery grounding wire is removed, the diagnostic code memorized by the equipment in the electronic control area will be automatically cleared. Therefore, before removing the wires, special equipment and instruments should be used to read the fault codes. 4. During disassembly and inspection, special tools and special instruments and equipment should be used as much as possible, and ordinary instruments should be used for inspection. Pay attention to the power supply voltage used to prevent damage to electronic equipment. 5. O-ring seals on fuel injectors and other assembly parts are disposable parts and cannot be reused. New parts must be replaced to ensure their tightness. 6. Generally speaking, there are few failures of the electronic control unit. If inspection is necessary, special instruments and equipment should be used. In general, disassembly and inspection are not allowed during the repair work. 46.
