The second ignition of a car is equivalent to starting a thousand times

1. The second ignition of a car is not equivalent to starting a thousand times. These two concepts are completely different.

2. Its meaning is as follows: a second start will be equivalent to 1,000 normal starters, that is to say, according to the industry standard, the owner has a record of 30 "second starts", and the gears on the outer edge of the flywheel and the motor shaft should be completely scrapped, but it doesn't matter occasionally.

3. The car engine ignited and ignited again. Occasionally, it happened once or twice, and the damage to the engine was almost negligible. If this is often the case, it will cause damage to the start-up gear of the starting motor and the flywheel gear ring of the engine.The start of the car is divided into key regular start, smart key induction knob type and one-button start.

4. It may be a leak in the high-voltage oil line that causes pressure relief. When the power supply is turned on, two. After three times, the high-pressure oil pump worked, so that the oil pressure was established and the car was put on.

5. When the vehicle is started, if the ignition is repeated, the secondary ignition will cause certain damage to the starter and ignition coil. But if it is only occasional carelessness, the time is short, and the number of times is small, it will not cause too much damage. It is recommended to avoid this situation as much as possible in the future. Because it was locked for the second time, it couldn't be unstwewed at all.

How much is the second maintenance of the 4s store? What are the contents of the second warranty of the car

1. The second maintenance generally requires the maintenance of the oil and filter, as well as the maintenance of a series of items such as the engine and gearbox.The second maintenance of the car costs about 800 to 1,000 yuan. The second maintenance item is similar to the first one, which is basically to change the oil and oil filter.

2. The cost of secondary car maintenance is similar to that of the main items. The market price of secondary car maintenance this year is about 400 yuan to 1,000 yuan. Among them, checking and replacing the filter and oil is the main item for the second maintenance of the car. Whether the owner is maintenance for the second time or several times, oil change and filter are essential items.

3. Under normal circumstances, the second maintenance of the car will cost about 600-1000 yuan. The second maintenance time of the new car is about one year after the first warranty of the car or after driving 10,000 kilometers, and the vehicle repair manual shall prevail. Moreover, the secondary maintenance of the vehicle belongs to the category of regular maintenance. Of course, the specific repair cost depends on the model.

Accumulate a little car knowledge a day (II)

Parking light Some cars have this situation: if you park If you forget to turn off the turn signal lever after turning off the engine, the small light on this side will stay on until your battery runs out. This is the parking light function.

SteamNot all models have rear wipers. Car rear wipers are common in SUVs or hatchbacks, but sedans have almost no rear wipers. This is because the sedan has more trunk cover, so the airflow will go backwards along the tail, thus taking away the dirty things on the rear window, so the rear wiper does not play much for the sedan.

Ensure visibility. Before starting the car, the driver should ensure good visibility. On rainy days, the rearview mirror is easy to get wet and blur the driver's vision. Be sure to dry the reversing mirror so that you can clearly observe the movement of the vehicle behind you while driving and react quickly.

No matter what brand your car is, they will make a clicking sound when we turn on the turn signal. This is because the turn signal can be turned on and off by relay, and thisThe principle of a relay is to rely on an electromagnet to repeatedly attract an electric shock, and it will make a sound every time it comes into contact.

Automobile Basics Collection Automobile Terminology Wheelbase (mm): The distance from the center of the front axle of the car to the center of the rear axle. Turning radius (mm): When the car turns, the center plane of the outer steering wheel of the car is the radius of the trajectory circle on the vehicle support plane. The turning radius when the steering wheel turns to the limit position is the minimum turning radius.

Car Common Sense Learning (II)

1. Not all car rear wipers are available. Car rear wipers are commonly found in SUVs or hatchbacks, but sedans almost do not have rear wipers. This is because the sedan has more trunk cover, so the gasThe stream will go backwards along the tail, thus taking away the dirt on the rear window, so the rear wiper does not have much effect on the sedan.

2. Ensure visibility. Before starting the car, the driver should ensure good visibility. On rainy days, the rearview mirror is easy to get wet and blur the driver's vision. Be sure to dry the rearview mirror so that you can clearly observe the movement of the rear vehicle while driving and react quickly. The phone number of the car accident. We drive on the road, and we can't guarantee that we won't have a car accident.

3. Why are the wheel hubs of buses and trucks convex and concave? In fact, the front and rear hubs used by buses are convex and inward. The reason why the concave surface is turned inward is that the concave part can have more space to install brakes and steering systems.

fourThis is because the turn signal can be turned on and off by a relay, and the principle of this relay is to rely on an electromagnet to repeatedly attract an electric shock, and it will make a sound every time it comes into contact.
