The Secret of Using a Car

The car is used for driving, but it also needs to be protected. In addition to daily maintenance, good car habits can also make the car less "sick." How to use a car is a good habit? Our editorial department has a strict set of detailed requirements for driving. These requirements are not "cheats", but some good habits that can be done with a little attention. Here, we have compiled a number of small details from getting on to getting off for the reference of the majority of driving netizens, so that everyone's car can be healthier.

1. Ignition

The first step in driving is naturally to start the engine. The traditional ignition switch has three gears. The first gear "ACC" is connected to a low-current power supply, and audio and air-conditioning electrical and electronic equipment are available. Some cars can use electric windows and electron mirrors in this gear; the second gear "ON" is connected The communication is related to the electrical equipment related to driving, such as ABS, airbag, oil pump, temperature detection and other systems; the third gear "Start" is to start the engine. When starting the engine, you should first stay in the second gear for about 3-5 seconds to allow the vehicle to perform a self-test. After seeing that many lights on the dashboard are off or fixed, the engine is officially started. It should be noted that for some cars that start without a key, pressing the button without stepping on the brake is equal to "ON". Pressing the brake directly and pressing the button is equal to the car. Therefore, the best habit is to press the start button without pressing the brake. Start the engine after self-test.

2. Hot car

Many car owners now know to warm up after starting the engine. Hot car is undoubtedly good for the protection of the engine. Its meaning is to let the engine reach the ideal operating temperature (80-90 degrees Celsius), and at the same time let the lubricating oil fully lubricate each component, and then only formally run under load to reduce wear.

There are two kinds of controversy about the hot car time. One is to wait for the engine to reach the normal temperature before starting. This is the best protection for the engine, but it often needs to run at idle speed for a long time. At this time, the engine consumes fuel and emits exhaust gas. Not environmentally friendly; the other is to drive the car for 1, 2 minutes, and wait for the engine temperature to increase slightly before driving, but do not operate at full throttle or full load during the first 1 or 2 minutes of driving, and drive normally after traveling at a moderate temperature. . In our opinion, these two methods are both reasonable and feasible, depending on your car environment. For example, if you like to enjoy driving as soon as you drive, you may wish to warm up for a long time; if your parking spot comes out on a large slope (this is the case in many underground garages), then start driving after fully warming up. Good; if you are in a hurry when driving, then the second method is preferable.

Some people say that the time to fully warm up is 1 minute, 3 minutes, 5 minutes... what should be the basis? In fact, the most scientific method is to look at the water temperature. Observe the water temperature gauge, it will gradually rise with the time of hot car. According to experience, the water temperature pointer can be seen in a car for 1-2 minutes, and some cars are relatively long. There are two possibilities. One is that the engine water temperature rises slowly, and the other is the water temperature gauge response is slow, but no matter what For cars, as long as the outside temperature is not extremely cold, it is generally possible to drive the car in idling hot car for up to 5 minutes.

Some cars do not have a water temperature meter, but there should be a low water temperature indicator (there will also be a high water temperature indicator, I hope you will never see it light up), this indicator usually waits until the water temperature is completely normal Extinguished, so when you use the car for the first time or two, you should pay attention to how long this light will go out when you start the engine at full idle speed, so that the estimated time for the water temperature to reach completely normal, usually after half this time, it can be slow Drive the car slowly.

3. Get started

After the car is hot, it is just starting. For manual transmission models, we always insist on starting at first gear no matter what the situation. Because the first gear has low-rotation and high-torque output characteristics, in addition to providing sufficient power to drive the car, it can also reduce clutch wear. Opening the manual gear should avoid half-clutch movements, which is particularly noteworthy for novices. The specific method is to remind yourself to remove the left foot from the clutch.

For automatic transmission models, only two pedals, brake and accelerator, control the speed, which is easy on the surface, but in fact, a bad drive can damage the car. When moving the car at low speed, the brake pedal is used to control the car to stop and go. At this time, pay attention to avoid the brake pedal being in a "semi-sticking" state for a long time, otherwise it will increase the torque converter in the gearbox. The wear and tear of such a long time will easily cause "internal injury" of the automatic transmission. The correct approach is to depress the brake pedal and release it decisively. The car must either move or not move at all. Never let the car "think about moving"-it hurts the car.

4. Direction

Driving directions is the basic skill of driving, and it is also one of the key links of car love. When parking and turning around, you often have to hit the steering wheel quickly and multiple times. At this time, you must not use too much force, because every time you "kill" the steering wheel, it will cause an impact on the steering mechanism. In addition, when the steering wheel is "killed", you should go back a little bit, do not stay in the "killed" state for a long time, because the steering power assist system will be in the state of maximum output power, which will cause the steering power assist system to overheat or overload for a long time. Protective start-up, power-assisted failure will also affect the life of the steering gear.

Attention should also be paid when making directions. If the front wheel is against some obstacles, such as a parking lot's limit lever, it is not suitable to drive the steering wheel sharply. If the wheel is on a bad road, especially a road covered with sharp gravel and you need to turn or turn around, you should avoid driving in place, otherwise the tire is easily damaged (equivalent to piercing sharp stones directly onto the tire) . The correct way is to slowly move the car while driving directions.

5. Wait for the red light

When walking in urban areas, it is common to encounter red lights. When we open the manual transmission, we will not hesitate to pull the hand brake neutral to liberate our feet. But what should I do if it is an automatic transmission? Is the D block stepping on the brake? Waiting for the green light, or hanging the handbrake in neutral, or P handbrake? We also have different approaches to this problem. If the waiting time is less than 30 seconds, we will wait for the D block to step on the brake; if it exceeds 30 seconds, we will pull the handbrake to engage the neutral gear; it is absolutely not necessary to hang the P gear in front of the traffic light, because the P gear must go through the reverse gear. In the gearbox, some unnecessary actions were made invisible.

6. Berth

Parking is a commonplace in urban driving. In our editorial department, parking is also very knowledgeable. Choose your parking space first, and try not to park next to cars that may cause trouble (such as small trucks, large cars); after parking the car, you should turn the steering wheel to the right. If you do not park the steering wheel for a long time, it may affect the tires. The positioning of the car may cause deviations, etc.; many parking spaces have a reverse limit lever. When the car is pushed back to the limit lever, do not immediately pull the handbrake to hang the P gear. You should hang the neutral gear, release the brake completely, and let the car slip forward, and then engage the P gear and pull the handbrake. This action can relieve the internal stress on the transmission and the handbrake, so that the gearbox and the handbrake are in place when parking. In the state of being compressed; the tire should be prevented from sloping up to the limit rod, which will cause considerable pressure on the tire's sidewall and increase the chance of tire damage; Finally, pay attention to parking on a narrow street. Keep your sights away to protect yourself and to facilitate others.

Some people like to park their cars on the road. In fact, this is very bad for the frame and tires. Should try to avoid parking the car on uneven ground (such as pressing sidewalk parking), because this will cause the frame to be deformed and chronically deformed. If you really have to stop, you should try to keep the coaxial wheels at the same height. For example, try to press both front wheels on the sidewalk, and leave the two rear wheels under the sidewalk. Do not let a particular wheel be at a different height. on.

7. Use car lights

The headlights are very power-hungry appliances. Try to avoid turning on the headlights when the engine is off (except for double-flash emergency lights). How to use the lamp while driving will also affect the life of the lamp. For example, the flashing of the high-beam headlights frequently and frequently will shorten the life of the bulb. When flashing the lights, the frequency should be slowed down to about half a second, flashing once or twice. In addition to prolonging the life of the bulb, it will also make the front car feel more polite.

8. Stop and stop

Before stopping and stopping the flame, all electrical equipment such as audio, air conditioning, and lights should be turned off, and then the flame should be turned off. This can avoid many electrical appliances working under the condition that the engine is not started before the next ignition, which increases the burden on the battery. If you are driving a turbocharged model, do not turn off the engine immediately after long-distance high-speed, you should idle for 3-5 minutes, because the turbine itself has a relatively high temperature when working, and rapid cooling after intense driving will damage the turbine to a certain extent. But if you can drive quite gracefully within a few minutes before parking, you can omit this process.

9. Pay attention to tire pressure

Before a long-distance attack, you should check some basic car conditions, such as the tire pressure of the tires and whether various oils are normal. Regarding tire pressure, the average car will be marked with different tire pressure values ​​according to different loads. Generally speaking, the empty load is about 2.2, and the full load is generally around 2.4. If the tire pressure is too low, there will be steering wheel weight, slow steering, high speed instability, etc., and too high tire pressure will cause excessive tire wear and will also affect the shock absorption effect. Special attention should be paid to the fact that the tire pressure should be high and not low when running at high speeds. Low tire pressure will increase the compression of the tire wall and increase the risk of high-speed tire puncture.

10. Check the oil

The oils that can be checked on the car are mainly organic oils, coolants, wipers, brake fluids, etc. Usually there are corresponding oil tanks and graduation marks in the engine compartment, which are between "MIN" and "MAX" The time is normal and can be checked visually. Some oils, such as brake fluid, cannot be adjusted by themselves, so you should check it yourself every time the car is done maintenance, and find a repair point to deal with the abnormal situation immediately.

11. Summary

All of the above are the basic requirements for our editors to drive and escort. It seems cumbersome, but when you get into a habit, it is actually a natural move. It will make you a popular driver, and it will make "your other" run more smoothly. I hope everyone can enjoy the fun of car and car like us.
