The harm of 2 hours of idling to the car, what is the harm of the car idling for a long time

Idle speed. It means stopping in place, not pressing the accelerator pedal, and letting the engine work at about 800 rpm for a long time.

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.

The opening is small, and the vacuum inside the intake manifold.

High, it is easy to draw oil vapor into the intake manifold, and some are deposited inside the intake manifold, forming similar carbon deposits.

of the substance, or coke. Prolonged low or idle speeds, especially turbocharging.

models, you will find that there will be a puddle of oil in the intake manifold behind the throttle, but this oil will generally disappear after running at 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.

It's parking and idling.

Still is. What about idling. If you stop and idle.

That's a little more fuel. If you are idling. It's discussed because of the speed of the stall drinking.。。 It's usually not a big deal.

The car will be idle for a long time will lead to an increase in carbon deposition, and the car is in a state of thick fuel injection when idling, that is to say, the car at idle, the valve is very small, and the fuel injector will spray a high concentration of oil to ensure the engine runs, so the idle speed itself is more likely to cause carbon deposition than the car running or running at high speed, and the engine carbon deposition will definitely be more severe when idling for a long time.

It can also cause damage to the vehicle's electronic equipment, and these electronic systems will go into standby mode because they have not received an operating signal for a long time when the vehicle has not been turned off. At this time, although the screen is still on, other parts such as the CPU will enter sleep mode. This is actually an anomalous mode of operation.

Therefore, after re-entering the car, some instruments or electronic devices may malfunction, black screen or freeze, or even display garbled characters.

What exactly does idling mean.

Idle speed means that the engine runs under no load, and only needs to overcome the frictional resistance of its own internal parts, and does not output power to the outside world. 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. Engines with good working performance generally have an idle speed of 550-800 rpm.

The idle speed can be adjusted by adjusting the size of the throttle opening, the amount of fuel supplied at the idle speed, etc. The best idle speed is the lowest speed at which the engine does not shake in the idle range and accelerates well.

The above content refers to Phoenix.com - what are the hazards of idling to the car, and long-term idling is easy to cause carbon deposits.

First, if the engine is idle for a long time, the throttle opening will be very small, and the injector will spray a high concentration of oil to ensure the operation of the engine, so the idle speed itself is more likely to cause carbon deposition than the car running or running at high speed, and the engine carbon deposition will definitely be more serious if it idles for a long time. As for the harm of engine carbon deposits, I believe that it is needless to say that it will directly affect the power and comfort of the car.

Second, people who have driven a car know that the fuel consumption of the car is quite scary when idling. According to the test, the fuel consumption of three minutes of idle is equivalent to the fuel consumption of one kilometer, that is, two hours of idling consumes almost 2-3 liters of fuel.

3. When the engine is idling, because the temperature and pressure in the cylinder are relatively low, the preparation time for fuel ignition is prolonged, and the sealing of the cylinder decreases at this time, so it is easy to produce a knocking sound and shorten the service life of the engine.

Fourth, long-term idling, the concentration of the engine mixture is too high, the oxygen content in the exhaust gas is low, and the mixture without complete combustion is burned at the position of the three-way catalytic converter, which is easy to burn out the three-way catalytic converter.

Hazards of carbon deposits.

1. Due to the change of the position of the throttle due to the carbon deposit on the throttle, when the engine is idling, the computer receives this error signal and calculates the wrong fuel supply, which increases the fuel consumption of the vehicle. And the carbon deposit on the throttle body can cause acceleration lag, idle instability, and the carbon deposit on the valve occupies the air intake space on the one hand, makes the inflation efficiency decrease, and directly affects the dynamics of the car;

2. On the other hand, the dry carbon deposit will also adsorb a large number of gasoline molecules in the combustible mixture, destroy the original mixture concentration, which will lead to the difficulty of cold start and the increase of fuel consumption, and the more serious carbon deposit will also make the valve closed loosely. In addition, the accumulation of unequal carbon deposits on the fuel injector affects the atomization of the fuel injection, resulting in the mismatch of the work of each cylinder, and may also cause obvious engine shaking.

There will be an impact, the most obvious is that more oil is burned, and carbon deposits will be increased, of course, engine wear is the most direct, and it is not a big problem, but don't do it.

Dear, hello, I'm glad to answer for you There is an impact on the car for a long idle time of the engine, and the impact is: shorten the service life of the engine; It is easy to burn out the three-way catalytic converter; This leads to an increase in carbon deposition in the engine; damage to the vehicle's electronic systems; Causing injector failure; Increase the hazard of freeze resistance.

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.

As long as the idle speed is long, the main reason is that the carbon deposit in the engine will increase. But it has no effect on the engine. You can rest assured that the car is not so fragile.

I believe that many people will idle their cars for a long time, sometimes for two hours, in order to wait for someone else in their daily driving. So, what are the dangers of running for a long time? First, if the engine idles for a long time, the throttle opening will be small, and the injector will delay in spraying a high concentration of oil to keep the engine running.

Therefore, idling itself is more likely to cause carbon deposits than driving a car or running at high speed. If the engine idles for a long time, the carbon deposits in the engine will definitely be more serious. As for the harm of engine carbon deposits, it is believed that it will directly affect the power and comfort of the car.

Second, anyone who has ever driven a car knows quite well that the idle fuel consumption of the car is quite scary. According to the test, the fuel consumption of idling for three minutes is equivalent to the fuel consumption of one kilometer, which means that idling for two hours consumes almost 2-3 liters of fuel. Third, when the engine is idling, the temperature and pressure in the cylinder are low, which prolongs the preparation time for fuel ignition, and the sealing of the cylinder decreases at this time, which is easy to produce detonation sound and shorten the service life of the engine.

Fourth, when the engine idles for a long time, the concentration of the engine mixture is too high, the oxygen content in the exhaust gas is low, and the incomplete combustion mixture is burned at the position of the three-way catalytic converter, which is easy to burn out the three-way catalytic converter. Generally speaking, it is okay to wait for someone to be idle for a short time. However, if the engine idles for a long time, there will be problems such as poor heat dissipation (especially in summer), poor emissions, and easy carbon deposit.

In short, it only brings harm, not good.
