As the temperature in winter is getting lower and lower, many people say that it is more convenient to travel by car, not only the travel efficiency has become higher, but also the driving car is also very warm.
Although driving in winter is a kind of enjoyment, it is still necessary for everyone to master a certain amount of car knowledge while enjoying it, such as doing hot car work for the vehicle before departure.
Especially now that there are more and more automatic models, many people use the car due to the lack of necessary car maintenance knowledge, which unconsciously brings harm to the car.
Let's take the hot car work of the automatic transmission car, because the automatic transmission model is different from the manual transmission model, so before the hot car work, it is especially necessary to master the correct hot car operation, such as the automatic heat stop car when the P gear or N gear? It's even more dangerous if you get it wrong!
Before figuring out whether to use P gear or N gear for automatic heating cars, we may wish to take a look at why we do hot car work!
Generally speaking, when the vehicle engine is quiet for one night, the oil inside the engine basically sinks to the bottom of the engine shell, coupled with the weaker temperature in winter, the fluidity of the oil becomes weaker, if the cold car is directly on the road, the parts on the engine will cause abnormal wear due to the lack of lubrication of the oil.
Therefore, winter vehicles need to do hot car work before they go on the road, and automatic models need to master the correct method, such as improper use of gears not only can not play the effect of hot cars, but also more dangerous, and even waste fuel!
In fact, as an automatic model hot car, many car owners will hang P gear or N gear, and the more correct operation is to hang P gear.
Usually, if the automatic car hot car hangs P gear, it not only ensures that the vehicle does not have the problem of slipping, but also improves the efficiency of the engine's hot car, and more importantly, it will not cause the engine to pull the cylinder.
On the contrary, when the automatic vehicle hangs up the N-stop hot car, if it neglects to pull up the vehicle handbrake, it inadvertently increases the risk of the vehicle slipping.
Therefore, it is more correct to hang the P gear when automatically blocking the heat car, which not only plays the effect of the hot car, but also ensures the safety of the vehicle, and can play a more fuel-saving purpose.
In addition, when the automatic transmission vehicle is hot, it is also necessary to grasp the appropriate hot car time, and try to control the hot car time at 30 seconds to 1 minute.
Because the hot car of the vehicle is in the idle state, if the hot car is too long, there will be insufficient fuel combustion, and eventually the engine will produce a lot of carbon deposits.
When the carbon deposit material is attached to the engine and oil circuit, it invisibly increases the fuel consumption, weakens the power of the vehicle, and even occurs the engine cylinder failure.
In summary, as an automatic transmission vehicle in the hot car, car owners must remember to hang up the P gear hot car, do not hang N gear like a manual heat stop car, do not wait for the vehicle to break down or danger after the regret Oh! What do you think about this?
