How long does the car have to idle

Idling is when you stop in place, don't press the accelerator pedal, and keep the engine running at about 800 rpm.

Short-term idling has no effect on the car, and long-term, such as more than 1 hour of idling, is not very harmful to the car, but there are the following two hazards:

1. It is easy to burn engine oil at idle. When idling, the throttle opening is small, and the vacuum inside the intake manifold is high, which makes it easy to suck oil vapor into the intake manifold, and some are deposited inside the intake manifold to form a substance similar to carbon deposits, or coking. Prolonged low or idle speeds, especially in turbocharged models, will find a puddle of oil in the intake manifold behind the throttle, but this oil will generally disappear after running high speeds.

Second, it is easy to accumulate carbon at idle speed. When idling, the general mixture will be thicker, so the idle mixture is thick for a long time, which is easy to make the engine carbon, and low-speed driving stop-and-go is also, such as "one foot of the accelerator and one foot of the brake", one foot of the accelerator just raised the speed, and then the brake is again, the engine is in a situation where it will be thickened and the amount of fuel injected will be reduced, and it is also easy to make the engine carbon.

In general, long-term idling does not hurt the engine much, the wear is very small, and there is no need to worry about the engine problems, that is, it is more fuel-intensive, and then the engine is easy to consume oil and cause some carbon deposits. Generally, idling for ten hours is nothing, and some people forget to turn off the ignition and idle overnight, and then the fuel tank runs out of fuel and turns off.

Even if the idle speed is 10 hours, there is no need to do any remedy, the engine can be regularly maintained and changed oil, now the engine is not so fragile, idle for a few days will not be fine, and try to avoid idling for a long time in the future.

Hello, for the car hot car, as long as the idle run for 2 to 3 minutes, there is no need to warm up the car for a long time, which will lead to an increase in the fuel consumption of the vehicle, and it is easy to produce carbon deposits.

Hello, this only needs to be idle for about 5 minutes when the car is cold, and this is mainly to make the engine work more stable when the car is cold.

Hello, if the vehicle starts cold, it will take 2-3 minutes, and the speed is high when it is just started, so that it can be warmed up faster.

Hello, this depends on the outdoor temperature, under normal circumstances, the general vehicle idling for about five minutes.

It is generally not recommended to idle in place for a long time, as long as you start for 30 seconds, you can drive on the road, do not accelerate sharply and brake sharply.

Hello, this refers to the cold car warm-up. When the car is cold, the speed will be higher, and at this time, it is enough to warm up until the engine speed drops to a normal level and stabilizes.

Even if the weather is cold, after the start, stop in place for more than half a minute. The effect of hot car is not good, and it is easy to produce carbon deposits.

Are you talking about hot cars? Generally, the speed of the cold car is relatively high when it starts, and when the speed returns to normal, you can start to walk slowly.

Normal is generally 700-800 rpm, too low the engine is easy to shake, too high is high fuel consumption, as long as it does not shake, design engineers want to try as low as possible in order to save fuel.

In the following cases, the idle speed will automatically increase by 50-150**1, cold start, and the water temperature is low; 2. The battery loses power; 3. Turn on the air conditioner and refrigerate.

If the idle speed of the car is unstable, the following hazards will occur:

2. If the idle speed of the car is too low, there will be potential safety hazards of stalling at any time during driving.

3. When the car is idling, it is possible that the spark plug or high-pressure bag will not work, resulting in the engine piston not working, causing severe shaking.

For a minute or half a minute, the oil can basically be lubricated, and then run at low speed for a while and then drive normally.

Is it a hot car, try to idle as little as possible, it is easy to produce carbon deposits, and you can cold the car and slow down the hot car.
