Do you want to warm up the car on the road if you don t drive it for several days in winter?

The vehicle can only be driven normally after it has been warmed up in winter.

Generally, if the car is hot for less than 1 minute, you can drive at a low speed.

Avoid heating on the spot, do not drive at high speed, should keep at a low speed, and the engine speed should generally be kept below 2000 rpm. When the operating temperature is reached (approximately 90-110 degrees Celsius), it can be driven at normal speed.

The main reason is that the temperature is very low in winter, the viscosity of the oil movement will increase significantly, and before operation, the lubrication system and cooling system of the engine have not established a normal circulation.

Heating up is actually the process of building various systems, and it should not take too long.

Winter Hot Car Steps:

After checking the appearance of the vehicle, insert the key and rotate to the ON position, let the car ECU computer perform a self-test, about 2 seconds, observe whether there is an alarm display on the dashboard, rotate the key to start, start the engine, idle for more than 30 seconds, hang a gear to start, then rise to 2nd gear, idle 100 meters, hang three gears, low-speed operation (engine speed below 2000 rpm), drive 300 400 meters, check the temperature of the dashboard water tank, start from low to high action, you can start to upshift operation and shiftWhen the temperature of the water tank is 80-90 degrees, it can drive normally, and the whole hot car process is controlled within 5 minutes.

In winter, it is better to start the car for 5 minutes before continuing to drive.

In winter, it is necessary to warm up the car when it starts cold. In winter, due to low temperatures, the viscosity of the engine oil increases, which greatly reduces the lubrication of the engine and transmission. If the car is not hot, the cold car is driven directly, and the wear and tear on the vehicle will increase.

As for how long it takes to warm up, it depends on the temperature at that time, the lower the temperature, the longer the hot car will be.

First, after the car has been parked for a long time, the oil in the engine flows back into the oil pan in the lower part of the engine. Therefore, when the engine is started after a long period of inactivity (e.g. overnight), the upper part of the engine is in a state of lack of oil and lubrication. It takes about 30 seconds after the start of the oil pump to deliver the oil to the pistons, connecting rods and crankshafts of the engine, which need to be lubricated the most.

But even if you start the engine and hit the road immediately, as long as you don't slam on the accelerator and keep running at a low speed, the effect is the same as idling.

Second, before the engine reaches the operating temperature (about 90-110 degrees Celsius), the fuel supply system is still too low to effectively vaporize the gasoline completely (as we all know, the temperature of the liquid rises to the boiling point). In gasoline has not yet been vaporized"Wet"When it is liquid, it is not easy to burn and start the engine. At this time, it is necessary to rely on the effect of the choke to prevent part of the air from entering the cylinder, so as to improve the mixing ratio of gasoline and air, and increase the engine speed so that the engine does not stall.

When the normal working temperature is reached, the automatic choke will naturally return to its normal state due to the action of the machinery; And the manual choke car must remember to put the choke back, otherwise because the oil-gas mixing ratio is too high, not only waste gasoline, horsepower is insufficient, and gasoline combustion is not completely black smoke. It takes about seven or eight minutes to ten minutes for a cold engine to reach the normal working temperature, depending on the type of car; And during this time, there is no need to heat up the car in situ, as long as it is not driven at high speeds.

Hello, no, generally the engine starts for about 20 seconds, the oil is all over the engine to lubricate, the current car is not as weak as before, hope, thank you.

When using the car in winter, it is necessary to warm up the car in advance, when the engine of the car can reach the normal speed. before you can start the car.

It's going to take a while. In winter, you should also pay attention to keeping warm and preventing haze.

Hot cars are a common topic, but there are still many misunderstandings among friends, so let's popularize it again. When the engine stops working for a long time, the body temperature gradually drops, and the oil flows back into the oil pan due to loss of pressure and gravity, as does the transmission oil. So when you start again, the engine temperature is lower, the gasoline burns poorly, and the oil lubrication is reduced.

In fact, it's not necessary, in fact, it's not necessary, and the current technology basically doesn't need to mess around.

No, it is OK to warm up the car once a week, if the car is not used, it is recommended to warm up the car for 15 minutes, if the vehicle is used, it is recommended to warm up the car for no more than one minute. If you have any questions, please feel free to contact me, if it helps you, please adopt.

It's common sense to get a hot car in winter. Hot cars serve two purposes. First, let the oil pump pump the lubricating oil to each lubrication part.

After a few days of resting, the car's oil basically returned to the oil pan. In winter, the temperature is low, the oil is viscous, just start the car, it takes a period of time for the oil to enter the surface of the friction pair, and the wear of the engine before the oil enters is very serious and irreversible.

Second, we all know a common sense, thermal expansion and cold contraction. That is to say, the gap between the engine in the cold car state, the clearance of each part can not reach the best level, especially the gap between the cylinder wall and the piston ring, as well as the crankshaft and connecting rod bearings, and the connecting rod and piston pin and other parts can not be matched in the best working condition in the cold driving state. So it's best to wait a minute, adjust the seats, adjust the mirrors, fasten the seat belt, see the water temperature gauge starts to move, then drive at a low speed, wait for the water temperature to come up, and then drive normally.

Winter is coming, and it is common knowledge that drivers know that they need to warm up their vehicles before driving on the road. Many people think that after ignition, it is safer to idle in place for a period of time before walking, and some people think that today's cars are not so squeamish and do not need to deliberately warm up the car. So, how do you properly heat your car in winter?

<> read the following instructions patiently, you may understand why the car is hot? It is necessary to warm up the car in winter, especially for car owners in the north, many people know to warm up the car, but they don't know why. In fact, the main reasons for hot cars are:

After the car has been parked for a long time, the engine oil flows back into the engine oil pan. As a result, the top half of the engine is devoid of oil lubrication after ignition, and the oil pump that starts about 30 seconds later delivers oil to the pistons, connecting rods, and crankshaft where the engine needs lubrication the most.

Cars are harmful and useless I don't know if you have noticed: when we start the car, we usually find that the tachometer pointer will stay for a moment at more than twice the normal idle speed (automatic.

model is more obvious). This is when the car ignites after the Hyundai car.

The computerized automatic control module (commonly known as ECU) injects more fuel into the cylinder in the fuel injection system to increase the engine speed, so that the cold car can quickly heat up. Depending on the outside temperature of each car and the ECU settings, not every car will have the same speed. Under normal circumstances, the engine speed will drop significantly within a minute after the cold start, so if you don't even want to wait for this short minute, the big foot gas will go.

This undoubtedly exacerbates the wear and tear of engine parts, which may not cause serious problems in the short term, but in the long run, it will shorten the life of the engine.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also pay attention to me, your like is the biggest help to me, thank you.

There is no need to warm up the car, because today's cars use more advanced technology and can start cold.

Yes, as this can reduce the degree of damage to the car from low temperatures and prolong the service life.

The car is your own town, not someone else's, a lot of hidden stools to see by yourself, my personal habit is, the first car self-inspection, and then wait for the airbag light to go out, in the ignition, summer appropriate 10 seconds, the speed is slightly lowered, in winter on the royal front appropriate length of about 1 minute, and then on the low speed, about 40 kilometers per hour, drive a few kilometers, slowly the water temperature up on the normal drive.

Nowadays, cars don't need to be heated in winter, and most cars have heated seats inside, and it will be very hot inside the car after driving for a while.

Cars, like people, need to warm up before doing sports, otherwise it is easy to hurt muscles and bones. The temperature in the winter season is much lower than in other seasons, and the temperature rise of the engine will be slower than in other seasons. When a vehicle is started, friction is created between the engine and all parts of the vehicle.

If these components suddenly go into high speed, they can cause damage in the long run. Therefore, it is necessary to preheat the car.

The correct way to warm up the car in winter is to start the car and drive at a low speed, so that the parts that have not had time to lubricate will not be damaged due to strenuous operation. At this time, we only need to control the engine speed at about 2000 rpm, and wait for the engine water temperature to rise before it can drive normally. But "heating the car in situ for a long time" is actually not right.

In-situ idling often causes insufficient combustion and excessive mixture, resulting in aggravated exhaust pollution, easy carbon deposit, and slamming on the accelerator to warm up the car in place. It is also undesirable, because at this time, the oil often has not reached the various parts, but it has begun to exercise vigorously, which will cause serious wear and tear to the car, and even cause the cylinder to be pulled in serious or good. However, it should be noted that if it is an EFI engine or a direct injection engine, we do not need to warm up the car for a long time, because this has little effect and will increase fuel consumption.

It is best to control the warm-up time to about one minute.
