Turn on the air conditioner for two hours and run in P gear.

Don't turn off the fire and turn on the air conditioner for two hours in P gear. In life, I believe many friends sleep with air conditioning on. This is highly recommended. Let's leave the air conditioner on for two hours to share the P file.

If the engine is not turned off and the air conditioner is turned on for two hours in P gear 1 P gear, the engine will always be at idle speed, which will lead to the instability of idle speed for a long time, thus affecting the engine power performance. Moreover, when the engine is working, it will consume fuel. If it is not turned off for a long time, it will lead to carbon accumulation and block the pipeline parts in the car.

In addition, when the vehicle turns on the air conditioner at idle speed, it must pay attention to maintaining ventilation to ensure the air circulation inside and outside the vehicle, otherwise it will be life-threatening. When you turn on the air conditioner in the car, carbon dioxide will accumulate in the car. If ventilation is not maintained, people in the car may be poisoned by inhaling high-concentration carbon dioxide, and toxic gases such as carbon monoxide will accumulate outside the car. If you have the habit of turning on the air conditioner in the car at ordinary times, you must pay attention to these problems to prevent life risks.

This car has been parked for three hours. Why?

If you forget to turn off the engine occasionally, stopping for three hours is actually nothing. Don't be too careful Although it will hurt the car a little, the degree of damage is very small. When the car is running at idle speed, the engine needs to consume fuel, which will continuously produce tail gas, such as carbon monoxide, sulfur dioxide, lead-containing compounds, phenylpropyl pyrene, solid particles and so on, which are all environmental pollutants. Therefore, we should cultivate the habit of checking the car's flameout state when getting off the bus.

If the owner stops for a short time, it is recommended to hang N gear. Although P gear is safer, if it is not turned off for a long time, the internal gearbox of the car will be worn to a certain extent. It is more appropriate to put the N-range handbrake when parking for a short time, such as waiting for passengers or waiting for a red light.

P block the air conditioner for two hours without turning off the engine, and P block the engine for two hours without turning off the engine, which is harmful to the car.

It is possible to turn off the engine without shifting P gear before turning off the engine, but it will damage the gearbox and the engine. It is recommended to shift the P gear before stopping the engine. P gear is to lock the output shaft of the transmission mechanically to fix the car, and its function is to prevent the car from moving.

The most suitable parking and driving sequence of the vehicle is to wait until the vehicle stops on a flat road, then change the gear of the vehicle from D to P, finally stop with the hand brake, and then turn off the engine.

P file function:

P gear is a parking gear. When P gear is engaged, the engine will lock and the cart will not move, while N gear is neutral, which just separates the contact between gears, so the engine is not locked and can be pushed. Generally, if the N gear is engaged for a short time, it is necessary to pull the handbrake, otherwise it is easy to slip. If you need to stop for a long time, change to P gear.

Only after the vehicle is fully braked can it be put into P gear. Although it is possible to shift N gear when the vehicle is driving, if it is necessary to shift D gear when driving, it will cause damage to the gearbox, such as tooth-punching.

Turn on the air conditioner for two hours without turning off the fire. 3 It is not recommended to turn on the P-rated air conditioner without turning off the engine, because the battery carried by the vehicle is very small. If the air conditioner is turned on when the vehicle is idling, the engine needs to be started. However, when the engine is idling, the fuel will not be fully burned, and a lot of pollutants, especially carbon monoxide, will be released, which will cause harm to the human body.

Engine idling for a long time will cause carbon deposition. After carbon deposition, the engine pressure will be insufficient, which will affect the dilution of the mixture in the engine. When carbon deposits are attached to the intake valve and throttle valve, the engine cannot accurately adjust the fuel and air sent into the combustion chamber, which will cause engine vibration.

Matters needing attention

Static migration

Before shifting any other gear into P gear, you must stop, otherwise it will damage the locking mechanism in the transmission and the shift switch in the transmission.

Brake by hand first.

If you park on a ramp, you must first apply the hand brake and then put on the P gear. P-gear is similar to the lock with gear in manual gear, and it is not the main braking mode, but plays the role of auxiliary braking. There is a certain gap between the locking pawl in the gearbox and the outer ring of the output gear. If the car slides on the ramp, the gears and pawls will have a strong impact.

Although the parking pawl is hard, its volume area is relatively small. Compared with the vehicle weight of more than one ton, frequent impact will definitely wear the locking parts, and it will be difficult to move the P gear next time because the pawl is too tightly engaged with the gear.

The discomfort caused by this impact vibration to the people in the car is also obvious. As an auxiliary protection, the variable speed gear brake is used together with the hand brake and should not be used alone.

No traction

When engaged in P gear, the drive shaft is mechanically locked and the trailer cannot be driven out. If you need a trailer, you should put it in N gear, or lift the driving wheel off the ground first, and then put down the handbrake to pull the non-driving wheel.

P blocks the air conditioner for two hours without turning off the fire, and 4 p blocks the air conditioner for three hours. How much oil does it take to sleep in the car for one night?

First of all, turning on the air conditioner in P gear will definitely increase fuel consumption, because the compressor of the air conditioner needs to be driven by the engine, and when the engine runs at a low speed, the distribution ratio of the output of the air conditioner compressor increases, and the engine load also increases.

However, the fuel consumption parameters of idle air conditioners are uneven for different models, different displacement sizes and different engine adjustments. According to relevant tests, the fuel consumption of Volkswagen Sagitar with 1.4L displacement is 2.5 liters, that of Honda Civic with 1.8L displacement is 4.6 liters, and that of Land Rover Range Rover with 5.0L idling air conditioner is 6.6 liters.

According to this set of data and the current oil price of No.95 gasoline in 6 yuan, it is estimated that it will take 45 yuan, 82 yuan, 1 18 yuan to turn on the air conditioner for 3 hours in P gear. So if you turn on the air conditioner in the car at night and sleep for 10 hours, you need 150, 276 and 390 yuan respectively. So it seems that the cost of sleeping in the car is not low, and it is not harmful to the car and the human body.

On xx, xx, an accident occurred in the parking lot of the traffic control center of XX Public Security Bureau. Two men died of suffocation due to lack of oxygen in the brain inside the car. It is understood that the two men were sleeping in the air conditioner in the car, which eventually led to the accident.

Because the air in the car is not circulating, the engine emits high concentration of carbon monoxide. Once the exhaust gas flows into the car, it will cause human carbon monoxide poisoning, and the car will also produce a lot of carbon deposits when idling for a long time, which is harmful to the car and people. Regardless of fuel consumption, health is the capital of everything.

Therefore, for your own safety, you should turn on the air conditioner in a ventilated environment, or open some windows. It is strictly forbidden to stay idle in a closed car for a long time.
