1.高转速伤车

1. High speed injury to the vehicle

发动机的工作效率和转速有关，很多人都说发动机的转速越低越省油，毕竟在一定时间内，活塞的往返次数越少油耗也会越少。但是长期怠速行驶会使得发动机产生大量的二氧化碳，它们很少的一部分被排出去大多数都会堆积在发动机内，使得汽车油耗增长，动力减弱，增加油耗。

The working efficiency of an engine is related to its speed. Many people say that the lower the engine speed, the more fuel-efficient it is. After all, within a certain period of time, the fewer times the piston travels, the lower the fuel consumption. However, long-term idling can cause the engine to produce a large amount of carbon dioxide, a small portion of which is discharged and most of it accumulates in the engine, leading to increased fuel consumption, reduced power, and increased fuel consumption.

2.停车挂P挡毁车

2. Parking in P gear to destroy the car

其实汽车在设计的时候就做了相应的措施，对于挂什么挡停车并没有什么规定，只要可以将汽车停下来，怎么方便怎么来。

In fact, corresponding measures were taken during the design of the car, and there are no regulations on which gear to park. As long as the car can be parked, it is convenient to do so.

3.汽车要定期保养

3. Regular maintenance is required for cars

其实4s说的时间都是比较短的，没必要听，但是心里一定要有谱，三元催化器需要定期清理，使用专门的清洗剂可将上面的污渍清洗干净，还可以清洁化学物质，提高催化器转化效率，降低污染物排放。

In fact, the time mentioned by 4S is relatively short, so there is no need to listen, but one must have a plan in mind. The three-way catalytic converter needs to be cleaned regularly, and using specialized cleaning agents can clean the stains on it. It can also clean chemicals, improve the catalytic converter conversion efficiency, and reduce pollutant emissions.

4.启动就走很伤车

4. Starting and driving can be very damaging to the car

以前需要三五分钟热车是因为当时的技术不好，如果不热车燃油雾化效果不好。而现在汽车都是电喷，直喷，冷车启动三十秒就可以了，或者是先慢起步等到温度上来之后再恢复正常速度就好了，不然只能让燃油白白浪费。

Previously, it took three to five minutes to heat up the car because the technology was not good at that time. If the car was not heated up, the fuel atomization effect would not be good. Nowadays, cars are all equipped with electronic fuel injection and direct injection. It only takes 30 seconds to start a cold car, or you can start slowly and wait for the temperature to rise before returning to normal speed. Otherwise, it will only waste fuel.

5.频繁更换机油

5. Frequent oil changes

机油对发动机主要起到润滑减震的作用，其次还可以防腐除锈。但是长时间使用就会变质，对发动机的保护减弱，所以要更换，但如果使用的是半合成机油必要5000公里换一次，7000公里换一次就可以，如果是全合成的最起码跑到10000公里再更换一次。更换频繁也会对发动机造成损伤。

Oil mainly plays a lubricating and shock-absorbing role in the engine, and can also prevent corrosion and rust. However, long-term use can cause deterioration and weaken the protection of the engine, so it needs to be replaced. However, if using semi synthetic oil, it is necessary to replace it every 5000 kilometers, and every 7000 kilometers is sufficient. If using fully synthetic oil, it should be replaced at least once every 10000 kilometers. Frequent replacement can also cause damage to the engine.
