1.高轉速傷車

1. High speed injury to the vehicle

發動機的工作效率和轉速有關，很多人都說發動機的轉速越低越省油，畢竟在一定時間內，活塞的往返次數越少油耗也會越少。但是長期怠速行駛會使得發動機產生大量的二氧化碳，它們很少的一部分被排出去大多數都會堆積在發動機內，使得汽車油耗增長，動力減弱，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.停車掛P擋毀車

2. Parking in P gear to destroy the car

其實汽車在設計的時候就做了相應的措施，對于掛什么擋停車并沒有什么規定，只要可以將汽車停下來，怎么方便怎么來。

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.汽車要定期保養

3. Regular maintenance is required for cars

其實4s說的時間都是比較短的，沒必要聽，但是心里一定要有譜，三元催化器需要定期清理，使用專門的清洗劑可將上面的污漬清洗干凈，還可以清潔化學物質，提高催化器轉化效率，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.啟動就走很傷車

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

以前需要三五分鐘熱車是因為當時的技術不好，如果不熱車燃油霧化效果不好。而現在汽車都是電噴，直噴，冷車啟動三十秒就可以了，或者是先慢起步等到溫度上來之后再恢復正常速度就好了，不然只能讓燃油白白浪費。

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.頻繁更換機油

5. Frequent oil changes

機油對發動機主要起到潤滑減震的作用，其次還可以防腐除銹。但是長時間使用就會變質，對發動機的保護減弱，所以要更換，但如果使用的是半合成機油必要5000公里換一次，7000公里換一次就可以，如果是全合成的最起碼跑到10000公里再更換一次。更換頻繁也會對發動機造成損傷。

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.
