Winter is coming, the steam temperature drops, how to heat up the car properly before driving?

Riders often discuss whether they need to warm up the car before driving. Both opinions are half and half each. Do you want to warm up the car?Especially in winter. And why?

Actually, don't look at the car so squeamishly. Now the quality of the vehicle is more reliable. As long as it's not intense driving, it's not so easy to break.

When it comes to hot cars, based on my years of experience in managing vehicles, hot cars are still necessary. In summer, the temperature is high, and many people turn on the air conditioner as soon as they get in the car, which is a bad habit. When the vehicle is parked for a long time, the engine and transmission lubricants all sink due to gravity.

When started, it takes at least a few seconds for the oil pressure to reach each part. Turbocharger cars, in particular, can be longer. In this case, if the air conditioning load or driving load is turned on immediately, it will inevitably have an impact on the engine or transmission.

The best way to do this is to wait for the idle speed to stabilize and then drive a few hundred meters slowly in first gear, and then drive normally. That is, to replace the hot car with a run.

Winter is different. The air temperature is low, especially in the cab. Operating as in summer can cause the glass to fog up or people to get cold in the cab.

The correct way to do this is to depress the clutch in a manual transmission and start the engine. The clutch can be released slowly immediately after starting.

After the idle speed is lowered, you can increase the gas pedal to 1500-2000 rpm and run for 1-2 minutes. This is about 3 minutes before and after. Engine and transmission lubrication has been effective.

At this time, the water temperature of the engine has not yet reached the working standard. Then the warm air may not be enough to remove the box. You can drive at low speeds in gear.

In winter, it is best to warm up the car for about 3 minutes. There are models that are electronically heated. Then you can drive in about 1 minute. Ordinary models operate according to the above, which not only does not harm the car, but also ensures that their ambient temperature is appropriate. Why not?

Of course, some people say that there is no need to heat up the car, but the water temperature does not rise, the cab is relatively cold, and the driver is very uncomfortable.

After entering the car and turning on the power supply of the whole car, do not rush to ignite, hang the gear to the second gear, let the electrical appliances in the car heat up properly, remove the moisture on the circuit, and idle in neutral gear after starting the car, if the car instructions allow.

In winter, we should start the car first and wait for the machines in the car to run relatively hot before leaving, which can effectively protect the car.

First we stepped on the brakes to ignite the ignition, then put into neutral gear, and the car warmed up for about three minutes, and when the water temperature reached 90 degrees, we were ready to drive.

Start the car yourself for 15 minutes, then let the car rpm down to 800 rpm before you can drive the car away.

I'm right, when Shi Zheng drives in the winter, he must first take the car and wait for about 20 minutes, and in the middle of the hot car, he can't drive the car away, because only by doing this is the most correct way to warm up the car.

Correct, be sure to start the vehicle, in situ hot car 30 seconds after the posture of the ear cover should be driven at low speed, this family can make the temperature of the engine slowly rise, do not suddenly step on the brakes to make trouble, do not suddenly step on the accelerator.

The correct warm-up of the vehicle in winter: the vehicle starts, the engine idles, idling for 1 minute, and then the vehicle travels at a slow speed for 5 minutes, and the vehicle can run normally after the engine coolant temperature rises.

In winter, it is best to warm up the car for a few minutes before starting it, because 90% of the wear and tear of the engine comes from the cold start wear and low temperature wear of the vehicle.

In summer, due to the high temperature, the oil in the engine is smoother, which can reduce the friction in the engine. In winter, due to the low temperature, the oil also begins to solidify slowly, and the viscous oil makes the friction in the engine increase, which will inevitably lead to greater wear and tear of the engine, and when using the car, it will be found that it is very difficult to ignite the car, because the viscous oil cannot reduce the friction.

Therefore, it is very necessary to preheat the car in advance before driving, so as to heat the engine oil in advance, so that the engine oil becomes lighter, and the softened engine oil can reduce the friction in the engine very well, so that the operation of the car is more smooth.

The correct way to warm up the car is to start it in winter, the water temperature will be lower than normal, and you can gradually accelerate 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 speed of the cold car on the road is controlled within 2000 rpm, and the moving gear car should be maintained in D gear below 2000 rpm for 3 5 minutes, in general, even if the automatic transmission car in good condition does not step on the accelerator, the low speed at idle speed is enough to make the vehicle walk forward slowly, at this time the automatic transmission will not upshift, the oil in the gearbox can be fully circulated, and the oil viscosity gradually returns to normal. Similarly, when the hand of the water thermometer rises by nearly 60 (more than one-third of the level of the water thermometer), it can accelerate normally.

Keep in mind that the longer the idle hot car is not always better. When the car is hot for a long time, the engine does useless work, wastes fuel and is not conducive to environmental protection. Generally speaking, the temperature is low in winter, and the viscosity of the oil at the bottom of the engine is relatively high, and the hot car time needs to be a little longer, generally 3 to 5 minutes.

The simple judgment is to look at the tachometer pointer to within 1000 rpm, and the water temperature gauge starts to move to drive normally.

Second, don't slam on the accelerator while idling. It's best to drive smoothly at around 40 yards per hour for the first 2 to 4 kilometers of driving. Failure to do so will cause rapid wear and tear on the engine and cause serious damage to the engine components.

Finally, a small displacement hot car must be thorough, such as a 3-cylinder or 4-cylinder displacement. Because the small displacement means that the power is small and the load is large, the machine can not stand it when the car runs cold, on the contrary, the car with a large or slightly larger displacement can basically go with temperature. Generally speaking, if you do the above 3 points, you can do it!

Isn't it simple?

After starting the vehicle, wait about 30 seconds to 1 minute before you are ready to hit the road. This time is mainly for the oil to enter the engine and lubricate it thoroughly.

Wait until the water temperature rises to normal before increasing the throttle. This reduces harmful emissions while avoiding wasted fuel, and makes the engine healthier.

Hit the road 30 seconds to 1 minute after activation;

Keep the speed low, the engine speed is generally kept at 2000 rpm;

After about 3 to 5 minutes, the engine temperature rises to normal operating temperature, and then normal driving can be resumed.

1. Start the vehicle, don't rush to the road first, hang neutral, and let the engine be dedicated for a few minutes.

Today's latest bear on the question of the correct way to warm up in the Northeast winter, and also collected information on the Internet about the correct way to warm up in the north of the winter. Let's share it with you.

1.Standard warm-up procedure: Turn on the car for half a minute to a few minutes, then drive at low speed (or even step on the accelerator) for a few minutes to bring the rev back to normal, and then you can drive normally.

2.Specific steps to warm the car: You can start the car until the clock. Drive at high speed at this time, keep your speed low. Check the water temperature gauge when driving at low speeds. If there are marks, you can shift gears appropriately. When driving, the car has been fully warmed up and can drive normally.

3.Special reminder: to correctly grasp the hot car time, the correct hot car method will greatly reduce the service life of the car, some lanes will be hot for a long time when it is hot. Doing so can cause carbon deposits and damage to the car. There are some injuries caused by pressing the throttle directly.

4.Attached: Winter hot car.

5.When the car is parked for a long time, the oil in the engine flows back into the engine's bottom shell. When the car is started, the oil cannot be lubricated from the oil pan for the first time, causing wear.

Over time, it will reduce the life of the car. If the car is hot for too long, it will also cause damage to the car, accelerate the deterioration of the engine oil, and cause carbon deposits in the cylinder head, pistons, and valves.

I hope it helps you through this article, and this is the end of the article.

The correct way to warm up the car should be to hit the road 30 seconds to one minute after starting, but never drive at high revs at this time, and keep it at a low speed.

The engine speed is limited to no more than 3000 rpm, and generally maintains 2000 rpm, otherwise the engine and gearbox are subject to intense wear and tear that cannot be recovered. Wait for the engine temperature to rise to normal operating temperature (it will take 3 to 5 minutes) and then resume normal driving.

The main reason for a hot car is that after the car is parked for a long time, the oil in the engine flows back into the oil pan in the lower part of the engine. Therefore, after ignition, the upper part of the engine is in a state of lack of lubrication without oil, and it is about 30 seconds after starting that the oil pump will be used to transport the oil to the pistons, connecting rods and crankshafts that need to be lubricated most in the engine.

First of all, let's figure out why the car is hot? Because, after the car has been parked for a long time, the oil in the engine flows back to the oil pan in the lower part of the engine. The upper part of the engine is in a state of lack of oil and lubrication, and it is about 30 seconds after starting that the oil pump is running and the crankshaft is splashing.

In winter, the longer the better. Ignition about 30 seconds can go, try to step on the accelerator as lightly, so that the engine speed does not exceed 2000 rpm, after driving for about seven or eight minutes, the water temperature of the car will rise, when you see the water temperature gauge pointer floating, you can drive normally, turn on the air conditioning and heating.

The main purpose of the hot car is to fully lubricate the engine components, lubricate the components of the automatic transmission and establish the initial oil pressure. The time of the hot car is not as long as possible, too long the hot car is easy to cause the engine recoil to increase the engine load, the hot car is still the mantra to maintain the car in winter, and the hot car only takes 100 seconds.

A hot car is a must before the car goes on in winter! The temperature in the Northeast is very low in winter, so it is recommended to warm up the car for 4-5 minutes or change the idle speed to normal conditions, and then you can drive on the road!

Warm up for 20-30 seconds after starting the cold car, then drive slowly for 3-5 minutes. Preheat the machine before it allows the oil to get where it should be inside the machine. Slow driving preheats the gearbox, so that the transmission oil fully reaches all parts.

(1) It is very necessary to start and preheat the car, because the temperature of the engine that has just started is low, and the lubricating oil of each part is not in place.

2) But the warm-up time does not need to be too long, and the criterion for judging is: the water thermometer pointer just starts to move, or the engine tachometer falls back to the idle state after starting, and it takes about a minute.

3) It is recommended that the owner start the first 2 kilometers after driving at a low speed, and then increase the speed normally.

The right way to warm up in winter:

Warm up the car for one to two minutes, then start slowly, warm the car as you drive, and then reach the normal driving speed. In short, try to keep in gear for a little longer than usual. Some drivers omit the warm car step, which not only wears out the vehicle, but also leads to incomplete initial combustion of gasoline, resulting in increased fuel consumption.

In general, the northern winter hot car for about 3 minutes, the temperature gauge moves, or the idle speed is reduced to below 1000, you can drive away, drive with a small throttle, and the water temperature will come up after a few minutes, and you can speed up. It takes 1-3 minutes to warm up in the southern winter, and the throttle is small.

In winter, the longer the better. In the northern winter, the hot car lasts for about 3 minutes, the temperature gauge moves, or the idle speed is reduced to below 1000, you can drive away, drive with a small throttle, and the water temperature will come up after a few minutes, and you can speed up. It takes 1-3 minutes to warm up in the southern winter, and the throttle is small.
