How much is the right amount of car to idle and how long the car can be idling

Hello, the idle speed is generally between seven hundred and eight hundred, too high fuel consumption will increase, too low will lead to easy stalling or unstable idling. I hope mine is helpful to you and I wish you a pleasant ride. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, not every car has the same engine speed (idle speed) at idle, but it is generally between 700 and 1100 rpm. If it is a carburetor car, it can be adjusted manually; If it is an EFI car, you don't need to adjust it. The injection volume (injection pulse width) of the EFI truck is controlled by the computer, and the computer will control the idle speed by adjusting the injection pulse width.

Hello, generally around 800 rpm. I hope mine can help you and have a great day! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, it is generally around 800 rpm. Have a great trip. If I can help you, please set it to, thank you!

Hello, it is normal for the cold car to be about 1000 rpm and the hot car to be about 750 rpm.

700-800 rpm If it helps, please set it, thank you.

Hello!! Most of them are! 800 rpm!! Thank you for the car question, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello car owner, the sedan idle speed 600 800 is normal. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

The four-cylinder car is 850 and the six-cylinder car is 750. [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

Hello, generally 700-800 is normal.

Look at what car, the sedan chair 800 turns and suitable.

Different models have different idle speeds

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.

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.

Idling the car for more than half an hour will hurt the engine. ‍

If the engine is not completely burned during long-term idle operation, it will produce more carbon deposits, and if the temperature is low, it will produce more, so the long-term in-situ heating car does not effectively protect the engine, but reduces the health of the engine.

As long as the engine is running, all the parts inside it are fully moving, and the oil is pumped out of the oil pump from the moment of ignition, constantly circulating in the engine to cool and lubricate. However, when the temperature is low, the viscosity of the oil will be very large, and a cycle time is required, which is about 20 seconds. Other parts that need to be "hot" are the fuel injection system and coolant, but this is also circulated in half a minute to a minute.

Even in the cold environment of winter, 1 minute of in-situ heating is enough, and after 1 minute it is not necessary. If you plan to idle on the spot to reach the standard speed and water temperature, I am afraid that you will not be able to do it for 10 minutes.

The only correct way to warm up is to drive at low speeds. After half a minute to 1 minute of the original hot car, the speed is stable, and you can put the gear on the road, control the speed not to exceed 2000 rpm, and gently shift the gear to refuel steadily, which is the most standard and correct method of hot car.

Energy saving, environmental protection, low carbon deposit.

In fact, even in very cold weather such as winter, it only takes half a minute to 1 minute to heat up the car in situ in winter, and it is not necessary to take a long time, and the time can be shorter in other seasons, and it is the only correct way to warm up the car slowly at low speed.

It is unlikely that the car was parked in the garage and idled for more than 30 hours, because the fuel in the standard fuel tank would run out in about 10-15 hours, excluding other factors.

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.

It can be as long as there is oil.
