How long does it take for you to warm up the car? How long does a hot car usually get hot?

What is the correct movement of the hot car? The engine using electronically controlled fuel injection will make the speed jump to more than 1000 or 2000 rpm after ignition, so as to complete the construction of the lubrication system in the shortest time and reduce wear. Pay attention to observation, you will find that the speed of more than 1000 and more than 2000 rpm is generally only maintained for a small period of time, most of which are more than ten seconds or tens of seconds.

Why is it not recommended to heat up in situ? Because in the summer, the actual hot car time only takes a dozen seconds, and in the winter, the hot car will be slightly longer, but there is no need to wait all the time. This means that there is no need to wait in place after the car is ignited; If you feel that the car is not hot enough, it is completely unnecessary to wait a few more minutes.

Some time ago, I just received a message from my friend**'s circle of friends, saying not to warm up the car. Then, I flipped through the forums and found that there have been many people who have had this problem. My personal opinion is that after stopping the cold car for a long time, it is generally when you get up in the morning and start it, the idle speed is more than 1000, and you will wait for about half a minute, one minute, and the idle speed will drop to 1000, and you will be ready to go. Slow.

In general, 3 to 5 minutes of hot car is fine.

It takes about seven or eight minutes to ten minutes for the cold engine to reach the normal working temperature, and the time for the hot car varies depending on the model.

Thank you.

The warm-up time is usually three minutes.

Now the vehicle in the cold start, the engine speed is particularly high, with the temperature is different, the cold start speed is not the same, the summer 20 cold start speed is about 1200rpm, the winter 0 below the cold start speed is about 1500rpm or more. Owners generally want to wait for the engine to drop to the baseline value of 700 to 800 rpm before driving, and the interval between this process is exactly 3 minutes.

The hot car of the car is mainly to preheat the engine to ensure that the engine is fully lubricated. On the one hand, after the engine is stored for a long time, the oil on the surface of the engine parts is all immersed in the oil pan, and if the parts want to work normally, the oil needs to be re-spread on the surface of each part, so as to prevent dry grinding between the various parts of the engine. On the other hand, the lubrication of engine oil is related to temperature, the lower the temperature, the greater the viscosity of the oil, the worse its fluidity, and the less likely it is to form a good and stable lubricating oil film on the surface of the parts.

So in general, we don't recommend car owners to drive vigorously in low temperatures, just drive slowly.

How long does a hot car usually get hot? Hot cars should hit the road 30 seconds to one minute after starting. However, at this time, do not drive at high speeds, keep the speed at a low speed, and the engine speed should not exceed 3000 3500 rpm.

Generally keep 2000 rpm. Otherwise, the engine and gearbox will not be able to recover from the intense wear and tear they have suffered. After the engine temperature rises to the normal working temperature, you can resume the driving method of personal habits.

The reasons for the need to warm up the car are as follows: Lack of lubrication: After the car is parked for a long time, the oil in the engine backs up into the oil pan in the lower part of the engine.

Therefore, the engine is started after the vehicle has not been used for a long time (e.g. overnight), and the upper part of the engine is in a state of no oil and lack of lubrication. Inefficient evaporation of gasoline: The fuel supply system cannot effectively vaporize gasoline completely due to the low temperature of the engine until it reaches its operating temperature (about 90-110 degrees Celsius).

Lubrication of transmission gears: Regarding the lubrication of transmission gears, this is the least understood and most easily ignored by ordinary people. Transmission gear oil, like engine oil, flows to the lower half of the transmission when the car is cold.

Only when driving, the bottom gear oil will be taken away by the movement of the gear to lubricate the upper half. @2019

I think it's okay to listen to the engine sound to be quieter, mainly the oil is up.
