Should cars start earlier in winter?

Winter start-up should be noted:

Before starting, you should turn on the ignition switch and wait for about 5 seconds to let the oil pump work before starting.

It is best to turn on electrical equipment such as lights and radios after starting the engine to work. Before stopping, turn off these power-hungry appliances and then turn off the engine.

Just don't fail to start the first time, and then ...... the second and third timesIn fact, this will only accelerate the consumption of electrical energy. And once the electricity is consumed, even the cart will not help. Therefore, if it fails to boot the first time, it is best to wait 30 seconds before making a second boot attempt.

Also, don't rush to drive at high speeds after the car starts, but give the vehicle a warm-up time, so that the vehicle is not easy to wear out and can improve fuel economy.

Generally, the water temperature of the vehicle should be at least 40 degrees Celsius or higher before starting to drive.

It is best to turn on the heater 15 minutes after the car starts or about 3 km, because this is when the engine is working properly.

Generally speaking, in winter, the temperature is relatively low, so it is recommended that you start one to two minutes in advance, so that the effect of hot car will be better.

Hello, you don't need to start it in advance this winter, you can start it normally and warm it up for about three minutes.

If you need to warm up the car to start in normal winter, you can generally preheat it in place for 30 seconds, and don't idle it for a long time.

Generally in a colder weather. The vehicle should be warmed up for one to two minutes before starting to ensure the overall performance of the engine.

Hello, the cold start of the car in winter needs to be warmed up, about 1 minute, and when the water temperature is normal, you can move forward in gear.

Hello, in winter, it is best to warm up for one to two minutes before driving, and the effect on the use of the car will be better.

Hello, if you need to warm up the car to start in normal winter, the vehicle engine can be driven below 1000 rpm.

In winter, it is best to warm up, preferably idle in place for about 1 minute, and then slow down for 1-2 km.

Under normal circumstances, when the vehicle is started, it should be warmed up for about one to two minutes, and then it is enough to start driving, and let the oil flow in place first.

In winter, because the temperature is relatively low, you can properly handle the hot car before driving.

The temperature in winter is very low, the vehicle is placed overnight, the viscosity of the car oil increases, if the cold car starts immediately, the damage to the vehicle is very large, so the hot car in winter is more critical. So how to warm up the car properly in winter

A lot of people know about hot cars, but they don't understand why they need to warm up. In fact, the premise of a hot car is that the car is left for a long time, and the oil in the engine flows to the bottom of the engine.

Therefore, after ignition, the upper part of the engine is in the absence of automobile oil and no lubrication, and it is about 30 seconds after starting, before the automobile oil will be transported to the piston rod, crankshaft and engine crankshaft and other components that must be lubricated by the engine due to the operation of the fuel injection pump.

I don't know if you've noticed: When we run a car, we usually notice that the tachometer hand is at a point where it is more than twice the normal idle speed for a moment (especially in automatic cars). This is also when the car is ignited, the system automatic module (alias ECU) on the modern car is to let the oil pump system software spray more gasoline and diesel into the cylinder to increase the speed of the engine, so that it can quickly increase the temperature in the case of a cool car.

The level at which the speed of the cool car rises depends on the external operating temperature of each car and the ECU setting, and not every car will have the same speed value. After the vehicle is in operation, the grease is not available at idle time, so it is most susceptible to damage. According to statistics, more than 90% of the damage to engine parts is caused within three minutes after the cool car starts.

Hence the winter. Especially in the cold winter, it is very easy to damage the engine by idling in place, so it is recommended that the car buyer choose to heat the car by driving slowly at low rpm.

After running in winter, the temperature will be significantly lower than normal, and it will not be able to slowly increase until the temperature is normal. Ignite the car and wait still for a while (the waiting time is the time when the speed is reduced and the speed is relatively stable, generally no more than one minute). For example, when the vehicle just landed, the speed was above 2000 rpm, and after about 30 seconds and 1 minute, the engine tachometer hand was reduced to about 1200 rpm (but it had not been reduced to the normal idle speed of 800 1000 rpm), and it was basically stable without obvious ups and downs, and the car body did not have obvious flutter when you could start in gear.

It is necessary to warm up the car in advance. Because the weather is very cold in winter, the engine will also be affected, so it is necessary to warm up the car in advance so that it will not damage the engine.

Need. Because the weather is cold in winter, warming up the car in advance can reduce the occurrence of breakdowns, so it is necessary to warm up the car in advance.

Yes, be sure to warm up the car in advance, so that you can avoid mechanical failures and protect the engine well.

After the start of winter, the water temperature will be lower than normal, and it will not be able to accelerate gradually until the water temperature is normal. After igniting the car, wait in place for a while (the waiting time depends on the relatively stable time after the rpm drops, generally no more than one minute). The most important thing is to avoid multiple starts in the cold engine state, because multiple cold starts will aggravate the wear of moving parts and reduce the overall working life of the parts and even the engine.

When the engine starts, it will determine the amount of fuel injected according to several basic signals: water temperature signal, crankshaft position signal, ignition signal, oil pressure signal, external temperature sensor, etc., and judge the time when the engine needs to heat up.

The correct way to warm up the car is to keep the speed low for 30 seconds to one minute after starting, and keep the engine speed at about 2000 rpm. Allow 3 to 5 minutes for the engine temperature to rise to normal operating temperature before returning to normal driving. It is not easy to drive immediately after the vehicle is preheated, and the vehicle should be driven 50 meters under normal idling, so that the wheel hoop, rear axle, and transmission can be lubricated, and it is not easy to wear the parts in the early stage.

Slow driving after starting, the lubricating oil for the gearbox, differential and axle needs to run at low speed for a period of time to be at optimal efficiency. Accelerate after the engine temperature is normal so as not to hurt the car.

In fact, the so-called hot car is very simple, that is, when traveling every day, slowly drive the car out of the parking space and drive out of the community, and it is best not to refuel the throttle in slow driving. In this way, the engine is running under light load, the low-viscosity oil is enough to protect the engine, and the engine raises the temperature much faster, the automatic choke valve returns to normal work relatively quickly, and the proportion of mixed gas and oil in the cylinder is normal in advance.

In winter, it is necessary to warm up the car outdoors (depending on the local temperature), and the bottom of the internal machine is required to be 40 degrees above zero. Here, it is also a reminder that it is not only necessary to warm up the car in winter when the temperature is low, but also to warm it up in summer, but for a shorter time.

Middle (around 0 degrees Celsius): Wait 30 seconds after starting the engine, and drive slowly until the water temperature gauge hand moves, and then you can drive normally. Many car owners always reflect when they start cold:

The engine noise is louder than usual, and sometimes there is a metal sound, but when the car is hot, it is normal, and it always feels like there is something wrong with the car, in fact, it is the cold car idle speed of the engine.

It is very necessary to preheat the vehicle, why do you need to preheat, in fact, it is very simple, the car also has a temperature, which is the most comfortable temperature for him, just like a person, at this temperature, you can maintain a good state, it is a truth. Then the fluidity of the engine oil will not change theoretically until it solidifies or is like diesel wax, and the difference is only that there is a difference in the fluidity of the engine oil at different freezing points. In this case, the speed at which effective lubrication is formed after a cold start of the engine will not be affected by normal fluidity.

The piston cylinder liner of the engine under cooling is not tightly sealed, and high-speed operation will cause the piston ring and cylinder liner to rub off. That's why Japanese engines are assembled in a cold air environment. Time: Wait about 2 minutes, just start at a low speed.

Some car owners believe that now the car manufacturing process is very good, and there is no need to preheat in situ just after the fire in winter, and preheating in situ will only waste more fuel, and it will also make the engine on the vehicle more likely to form carbon deposits.

No matter what the season is in a year, the length of time to warm up the car is different. Whether it is physical exercise or physiological exercise, it is necessary to warm up. People should move their joints and muscles before exercising, in order to move better and faster.

The same goes for mechanical movements. The in-situ hot car time should not be too long, and the long-term idle operation is easy to cause the combustion of the vehicle is not sufficient, and the engine carbon deposition and the three-way catalytic blockage, and can also increase fuel consumption. If the car is not hot, the friction damage of the parts will be increased after the direct action of the power, because the oil has not been thrown off and the flow is not good.

Because the car has been left for a long time in winter, the oil in the engine will flow back to the oil casing under the engine, and if the car is started immediately, the engine of the car will be unlubricated.

Because the engine of the car may be colder in winter, and may even have the problem of freezing, it is better to warm up before starting the car to better protect the life of the car.

Because the temperature in winter is very low, if you don't warm up in advance, there is no way to implement the various functions of the car during driving, so there will be traffic accidents when you are on the road, and you must warm up in winter.

In winter, it is necessary to start slowly, turn on the engine and let the car go slowly, so as not to damage the engine, if you just start the car without moving, it will not be effective.

1. Check the status of the battery.

Generally, the difficulty of starting the car in winter is mostly caused by the loss of battery power or the expiration of the battery service life. When the battery is low, the speed is weak when starting the car, and only the clicking sound is heard, and the clicking sound will gradually become a clicking sound when the ignition is lit again. Do not ignite continuously to avoid the battery running out of power.

Do not park the vehicle for a long time in winter, generally park the vehicle for a week to drive out for a circle, so that the battery power can be effectively replenished.

2. Change the appropriate engine oil.

In winter, as the temperature decreases, the viscosity of the engine oil will increase, and the oil flow will be difficult, so that the engine will increase the lack of wax resistance. If it is difficult to start the fiber, please check whether the oil label is incorrect.

The oil label consists of two parts: grading and viscosity specification. At present, most of the engine oils on the market use SAE and other grades to mark the viscosity, SAE is the abbreviation of the English "American Society of Automotive Engineers". For example, in 5W-40, "W" means winter, which refers to the low temperature viscosity grade of the engine oil, and the higher the number in front of it, the better the low temperature fluidity of the engine oil, which means that the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start.

It only takes 1 minute to warm up.

Some car owners wait 5-6 minutes for the car to heat up, but they don't have to. At present, the engine technology does not need to heat the car, and most of the car engines now use electronic injection engine technology, and the fuel supply computer can accurately adjust the oil and gas mixing ratio, so if you are in a hurry to start the car in the morning, you can not use the hot car.

When the car is warmed up for 1 to 2 minutes, the engine water temperature does not rise completely, and turning on the air conditioning system is more fuel-intensive, so you can't kick the accelerator right away. The correct approach should be: step on the accelerator slowly, automatic transmission vehicles shift according to the normal mode, manual transmission vehicles are between 2000-2500rpm, and can drive normally after the water temperature rises.

1. Slap the hood to expel possible small animals;

2. Clean the snow on the windshield and move the wipers;

3. Note whether the folding rearview mirror can work normally, if it cannot work normally, it should be carried out manually;

4. Start the vehicle to idle and warm up the car until the number of revolutions and water temperature are normal;

5. When in a hurry, you should idle and warm up the car and avoid intense driving;

6. Turn on the heater switch after the vehicle is warmed up.

I hope that my ruined ones will be able to get yours.
