The car idles for a long time, which not only hurts the wallet, but also hurts the body.
Unless the weather is particularly cold and hot, you must blow warm air and blow cold air, or it is recommended not to do this thing, even if you must idling for a long time, you must pay attention to the relatively correct and scientific method.
Tailpipes are more toxic for long periods of idleness
The first hazard of long idle speed is that the exhaust gas will be more concentrated.
It's like: eating junk food once in a while is indeed harmful, yes, but the problem is not big, it is good to be happy today; eat junk food for 3 meals a day, and eat it for 365 days, and the body may not be quite right.
Wang Luting of Beijing Jiaotong University has a master's thesis, "Research on the Impact of Motor Vehicle Idle Emissions on the Community Atmospheric Environment", which is mentioned above.
In the case of idle speed of motor vehicles, the engine is burned by poor oxygen, and poverty is poor poverty.
Under idle conditions, the concentration of HC (hydrocarbons) and CO (carbon monoxide) emitted by motor vehicles is higher than that produced by other operating conditions.
What do you mean? It is simply said: when the car is idle, the car does not move, the exhaust gas and air are mixed together, and it is sucked back, so that the combustion condition of the engine becomes worse.
It is more interesting that many countries have also introduced anti-idling regulations, to this level.
For example, in 2012, the Spanish Parliament passed the "Regulation on Fines for Parking Without Stopping", which imposes a penalty of 100 euros for motor vehicles parking on the side for more than 60 seconds, and does not turn off the fire when encountering serious traffic jams at high speeds.
There is also New York, the United States, roadside stops for more than 3 minutes without turning off the fire, 125 to 2000 US dollars in fines, the amount of fines is extended according to the number of minutes, and in the vicinity of the school, the law enforcement is more stringent.
In fact, there is such a policy in China, article 73 of the Beijing Municipal Air Pollution Prevention and Control Regulations stipulates that the driver should turn off the engine when stopping for more than 3 minutes.
Exhaust fumes can endanger driver health
But these are all pollution of the overall environment, right? It seems quite big to say, for us personally, long-term idling will also endanger physical health.
For example, on June 25, 2019, in the parking lot of Zhongfang County, Huaihua, Hunan Province, 2 men slept in the car with air conditioning on, and when they were found, the windows were closed, the air conditioner was turned on, and 2 men died due to lack of oxygen to the brain.
Or as mentioned in the paper just now: these carbon monoxides, hydrocarbons, and nitrogen oxides can induce various respiratory and lung diseases.
Motor vehicle emissions are low-altitude emissions, right? The closer the discharged harmful gases are to people, the greater the damage, especially for drivers in under-ventilated carriages.
It's like, you imagine: a person eating snail powder and stinky tofu in an elevator, the rich taste is stronger than the usual situation, right?
If you like to eat snail powder and don't care, it is the same as changing it to smoking.
If the summer is too hot and too cold, the car really needs to idle for a long time to turn on the air conditioner, for their own health, or to open a little window.
Open the external circulation, the air conditioning air volume is also opened a little larger, increase ventilation. Don't worry about oil money, the window is opened with poor effect, more expensive oil, don't worry about this at this time.
Wasted gasoline
In addition to a large number of exhaust gases endangering the environment and endangering the health of drivers, long-term idling will also waste gasoline, just money!
Previously we have taken the video measured, the 2017 Chevrolet Cruze 1.5L displacement, 1 hour idle fuel consumption of about 2.4L.
Now the price of oil is expensive, according to the average oil price of the 92nd in the past few months 7 yuan 5 / L to calculate, 1 hour idle is also 18 yuan gone, a takeaway money.
I also found some other models with hourly idle fuel consumption for your reference: Volkswagen Sagittarius 1.4T, 2.72L/h; Volvo S60 2.0T, 2.37L/h; Audi A6L 30FSI, 1.39L/h.
Idle fuel consumption is not proportional to the displacement, depending on the specific model, but the general 2L or so is not able to run, supercar what do not know, there is no opportunity to test.
Engine carbon deposits will be aggravated
Finally, the engine idles for a long time, and the engine will be more likely to accumulate carbon.
Yang Qi of Jilin University has a master's thesis, "Research on Engine Carbon Depositation Treatment and Evaluation Method", mentioned above.
Often in idle working conditions, the air flow into the engine is small, and the flushing of carbon deposits is not enough, which is more likely to lead to carbon deposits.
Just like there is dust on the table, wipe every day, not obvious, the table is still quite clean; 1, 2 years without wiping, you look at the table color has changed, a layer of ash.
The paper just now also mentioned that when the car is driving at high speed, it is possible to prevent the deposition of carbon deposits to a certain extent by increasing the air flow speed to wash the intake tract.
If there were more cases of parking idles and others in the past, and you happened to be on a business trip, you see, this kind of commercial vehicle situation, this method can also remove carbon deposits to a certain extent.
The method of more ideal effect and higher cost performance is of course to use a clean fuel treasure, the effect of carbon deposition is better, my family also sells, you can go to see.
Long-term idle exhaust is harmful to the environment and also accumulates carbon
In general, the exhaust gas emitted by idle for a long time is not only harmful to the environment and the health of drivers and friends, but also greatly damages our wallets.
Not only is gasoline wasted, but it also increases engine carbon deposits.
Carbon deposition and then get it back is also a cost and a cost, why bother?
Whether the automatic start and stop is fuel saving or destroying the car
In order to reduce the idle speed of friends, many cars are now equipped with a function called "automatic start and stop", in the end is this thing useful? Can it save fuel?
Some people are worried that this thing will destroy the car, will this be the case? Will the manufacturer deceive us? They're just there to accomplish what they call "environmental indicators" as well.
Automatic start and stop is not used, the expensive battery expires, I will change an ordinary battery to replace it, can I continue to use?
Materials, papers, and cases are all sorted out for you.
Keywords: start and stop
Want to see is very simple, pay attention to the WeChat public number "spare tire said car", reply to the keyword "start and stop" on it, start the start, not up.
I this public number, every day will give you a piece of car practical small dry goods, text version, audio version, video version, watch, listen to have, pick your favorite version on it, "spare tire said car" We will continue to talk tomorrow.
