What is the average idle speed of a car? How much normal is the idle speed of the car?

Different models, due to different engines, the idle speed value is different. The general idle speed value is in the range of 500 to 850 rpm, and the idle speed at the moment of cold start is about 1500 to 2000 rpm, and after the engine water temperature returns to 90 degrees, the idle speed is also kept within the specified stable value.

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.

The idle speed of each car is different, and there are also differences in the idle speed of the same car in different conditions. In the case of a cold car, the vehicle needs to idle at about 1300-1500 rpm, which is due to the need to quickly increase the water temperature and reduce engine wear. At other times, the vehicle is generally idle below 1000 rpm, and most of them are kept at 600-900 rpm.

Dear, this question is up to me, it takes a little time to type, please be patient, thank you!

Hello, I'm helping you sort out the answers to your questions, please wait a moment

Hello, the idle speed of a normal car is generally around 750 850, which is normal. If the idle speed is too low, the car will shake, too high the fuel consumption will be high, if it is high and low, it is generally the throttle carbon deposit should be cleaned, and there is time to clean it for a few days. The cost is about 80.

Engines with good working performance generally have an idle speed of 550-800 rpm.

The idle speed only needs to overcome the frictional resistance of its internal parts, and does not output power externally. The minimum speed at which an engine runs smoothly is called idle speed and is one of the five basic operating conditions of an engine.

The idle speed can be adjusted by adjusting the size of the throttle opening, the amount of fuel supplied at the idle speed, etc. Generally speaking, the lowest engine speed is best when the engine is not shaking in the idle range and the acceleration performance is good.

Classification of idling.

1. Normal idling.

The vehicle starts the engine in the parked state, and the lowest speed at which the engine runs stably is called parking idle speed (the process of the engine changing from the cold idle state to the idle state when the engine reaches the normal operating temperature is called warm or hot car).

2. Idle speed.

In the process of the car gearing, do not step on the accelerator pedal or release the accelerator pedal during driving, maintain the minimum opening of the throttle, and the engine speed and parking idle speed are consistent at this time, which is called driving idling.

The above content refers to Encyclopedia - Idling.

Generally speaking, it is normal for the vehicle to maintain an idle speed of about 800 to 1000 rpm when the car is cold started.

The idle speed of the car is generally between 700 and 1100 rpm, and if it is a carburetor carburet, 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.

The idle speed of the car is not a speed, but a working condition.

When the engine is idling, it is called idling. When the engine is running, if the accelerator pedal is completely relaxed, the engine is idling. The number of revolutions at engine idling is called idle speed.

The idle speed can be adjusted by adjusting the damper size, etc. Generally speaking, the lowest idle speed is the lowest speed when the engine is not shaking.

Do not do useless work - idle speed is to overcome the running resistance of the engine itself, maintain the minimum speed of the engine, so as to facilitate the driver to drive and temporarily stop in various situations. For example, when waiting for a traffic light, or in a traffic jam, although the time is short, temporarily turning off the engine can bring immediate energy saving and emission reduction effects.
