Do I need to idle in place to drive in winter?

Is it necessary to idle and warm up in place in winter? How do old drivers do it, save fuel and don't hurt the car.

For more than 3 minutes, the main damage is that the car idles for a long time or often idles for a long time, and carbon deposits are easy to occur in the engine cylinder, and the throttle valve will also be affected. When carbon deposits accumulate to a certain extent, the power of the car will decrease, and at the same time, it is easy to cause engine wear and tear over time.

At the same time, long-term idle will cause an increase in fuel consumption, and a large part of the fuel consumption in the process of using the car is because of idling, so we can find that the fuel consumption of the vehicle is often lower when running at high speed, which is precisely because the idle time on the high speed is very small, and the engine is in the optimal working condition, so it has high fuel economy.

Precautions for idling in place.

What the owner can do is to minimize the amount of time the engine is idling to minimize the damage. For example, the hot train time in the morning should not be too long, at most 1 minute in winter, and within 30 seconds is enough.

When waiting for the traffic light, it is best to turn on the automatic start-stop function, and if not, it should be hung into neutral in time to minimize the load on the engine. Usually, if you wait on the side of the road for more than 1 minute, it is best to turn off the fire directly.

In addition to wasting fuel, idling in place will also be damaged due to the increased burden on the three-way catalytic converter due to insufficient temperature.

30 seconds to one minute after starting on the road, but at this time do not drive at high speed, should be kept at a low speed, engine speed to no more than 3000 rpm, generally maintain 2000 rpm, otherwise the engine and gearbox are subject to intense wear and tear can not be recovered.

Therefore, the best way to warm up the car in winter is to drive at a low speed and constant speed as much as possible after starting, keep the speed within 2000 rpm, and wait for the water temperature to reach nearly 60 or more before you can drive normally.

In winter, the vehicle engine idles.

High, there are two main reasons:

1. Normal phenomenon, due to the low combustion temperature of the motor engine when the finch mill is absolutely cold, the gasoline atomization effect is not very good, so in order to achieve the combustion conditions in the engine cylinder, the fuel injector in the car will inject a large amount of fuel, the purpose is to accelerate the combustion, but at the same time, there will be too high idle speed, that is, the phenomenon of too high speed, which is generally normal, waiting for the engine temperature to rise, the speed will naturally decrease.

The vehicle idles normally.

2. Of course, there are also some vehicles that have been started for a long time in winter, the engine has become hot, but the idle speed still can't go down, at this time it is not normal, it is recommended to check the temperature sensor of the engine first.

3. In addition, it should be noted that the general vehicle needs to warm up the car in winter, that is, let the engine continue to run for 1 2 minutes after starting, and during this time period, the idle speed of the vehicle will quickly drop to the normal 500 700 rpm, and it can drive normally at this time.

The cold start idle speed is too high.

However, some vehicles may start in winter 3 5 minutes after the idle speed is still above 1000 rpm, at this time do not rush to characterize it as a fault, it is recommended to go to the vehicle repair shop to adjust the idle speed, if this is still the case, and then judge it as a fault.

In winter, the speed of the vehicle is not higher than that in summer, and the speed of the vehicle in winter is the same as the speed of the mass in summer, but its power output may be lower than that of the summer spine.

It is okay to start in place if you don't drive for a long time, but it is not recommended to idle in place. After the engine is started, it can be driven in gear for a period of time, which is good for the engine, transmission, battery, and tires of the car.

As soon as the engine is running, all the parts inside it are in motion, and the oil is pumped out of the oil pump from the moment of ignition, constantly circulating in the engine to cool and lubricate the engine. 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 low temperature environment of winter, 1 minute of in-situ hot car is enough, and it is not necessary after 1 minute of rubber base. 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. Half a minute to 1 minute after the hot car in the original Shiruji, the speed is stable, you can put the gear on the road, control the speed not to exceed 2000 rpm, gently shift the gear and refuel steadily, this is the most standard and correct hot car method.

The car is fine if it idles in place for two or three hours. The longer the idle time, the longer the engine reaches normal temperature, and the slower the rate of evaporation of gasoline when it is injected into the back of the valve, which creates carbon deposits. At the same time, if you are driving at idle speed, the air flow into the engine will be small, so the scouring effect on carbon deposits will be weak.

It will promote the deposition of carbon deposits, the body trembles when the vehicle idles, the car does not speed up fast when accelerating, and the fuel consumption also increases suddenly.

Idle consequences: 1. Idling does not mean that there is no fuel supply, only the minimum fuel consumption of the engine is provided for normal operation, which is equivalent to the separation of the engine and the car and does not add the load to the engine, and the normal speed at this time is 1000r min, that is, idle driving.

2. The pistons of the engine are not synchronized, when the vehicle is turned off, the cylinder intake valve of the engine can not be closed at the same time, and the gasoline sprayed by the working cycle can not be timely **, some unburned fuel will continue to be evaporated and oxidized, and some soft black carbon deposits will be produced in the intake pipe, especially behind the throttle.

3. When the valve forms carbon deposits, a part of the fuel injected into the cylinder will be adsorbed, which will make the concentration of the mixture that really enters the cylinder thinner, resulting in poor engine work, and the body will tremble when the vehicle idles, the vehicle will not speed up fast when accelerating, and the fuel consumption will suddenly increase.

<> "High Idle Speed When the Car Starts in Winter? After the repairman finished speaking, the car owner: Knowledge!

I believe that many car owners and friends will find that the idle speed of the car is high when it starts in winter? After the repairman finished speaking, the car owner: Knowledge!

Let's take a look at it together, first of all, this is a normal phenomenon, it is a setting of the car itself, the high idle speed of the car is cool, the car is parked for a long time, and the oil in the engine flows back into the oil pan of the lower part of the engine, so after ignition, the upper part of the engine is in a situation where there is no oil and lack of lubrication, and it is about 30 seconds after the start, the oil will be transported to the piston, connecting rod and crankshaft of the engine that need lubrication most due to the operation of the oil pump.

However, due to the high viscosity of the oil in the low temperature environment, the low temperature fluidity is poor, and the lubrication effect of many parts that rely on splash lubrication is poor. Therefore, in order to heat up the engine as soon as possible, and then make the oil reach the best lubrication temperature, the general engine is set up to increase the idle speed at low temperature, the purpose of which is very simple, is to reduce wear! This is mainly programmed to reduce engine wear!

There are many disadvantages when the car is cold, so the engine computer will increase the idle speed, increase the amount of fuel injected, and the water temperature will rise as soon as possible. When the water temperature rises slightly, the idle speed slowly decreases, the high idle state lasts for about 1-2 minutes, and the lower the water temperature, the longer it lasts.

As the engine temperature gradually increases, the idle speed will gradually drop to a normal state, in addition to preheating the engine, the preheating three-way catalytic converter also plays a certain role. The three-way catalytic converter is equivalent to the purifier of automobile exhaust, and its working environment is higher than the engine requirements, the minimum should be more than 250, 400 -800 is the best, if it is lower than this standard, then it will affect the purification effect of exhaust, resulting in exhaust emissions are not up to standard, in general, in most parts of China, after the cold start of the car in winter, the idle speed rises to return to normal, it takes about a few minutes, and the idle speed is almost not abnormal in summer.

Therefore, it can be seen that the impact of water temperature on the engine is very large, high or low are faulty, to timely maintenance, especially low water temperature, some owners think that it does not matter, in fact, the impact is still very large, affecting fuel consumption, accelerating the generation of carbon deposits, so the water temperature is low should also be repaired in time, in addition to the winter if the water temperature is low, the warm air is not hot, even no warm air, driving is not comfortable, the car repairman reminds everyone, when your car in the winter idle situation do not worry, this is not a car failure, There needs to be a short wait, and during this time, don't be violent with the car.
