7 oil in summer and 9 fuel consumption in winter, is it normal

1. First of all, the incorrect way of hot car leads to an increase in fuel consumption, and it is understandable to warm up the car, mainly to let each part get the full lubrication of the oil, so that the car can be restored to the best. However, many car owners are hot cars for a long time, which is not correct. 2. The correct way to warm up the car is:

Warm up the car for a short time (about 1 minute), at this time the speed is basically stabilized, you can start in first gear, slowly drive for a while, and then refuel and shift, the initial speed is not too fast, control at about 50.

3. Another is that it gets dark early in winter, and during commuting, it is generally necessary to turn on the headlights, and the power of the headlights is supplied by the engine's oil combustion, so the length of time to turn on the headlights also directly affects the increase in fuel consumption of the car.

4. Another reason is the battery, in the cold winter, the weather temperature is relatively low, the chemical reaction between the electrolytes inside the battery is not as sensitive as in summer, the efficiency of the battery decreases, and it will often cause the battery to lose points, and the engine needs more fuel kinetic energy to supplement the battery.

5. For the winter of increased fuel consumption, we have a lot of countermeasures, first of all, we often check the tire pressure and wear degree, if the tire pressure is too low or the wear is serious, it will naturally increase the fuel consumption, and it should be replaced in time.

6. Always pay attention to the spark plug, if the use time is too long, the energy of the car ignition decreases, the speed of the car can not be raised, or the speed is too slow, it is necessary to consider replacing the spark plug to avoid the increase in fuel consumption. Also, don't drive at high speed for long periods of time.

7. There is also the daily maintenance of the vehicle, as well as the cleaning of the items in the car, unnecessary things (many bottles of mineral water and other sundries) should be cleaned up in time, and there is the addition of high-quality gasoline (that is, some gas stations with a good reputation for refueling, rather than high-grade gasoline).

Hello, this is a normal phenomenon, I wish you a happy car [If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

Hello, this is normal. Due to the cooler weather temperatures in winter. When the vehicle starts, the amount of fuel injected is large, and the engine self-heating process consumes more fuel.

If you have a problem with the car, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

The reasons for the sudden increase in fuel consumption in winter are as follows:

1. Many people are accustomed to hot cars for the first time in winter mornings, but if they heat up the car for a long time, it is actually very undesirable, in addition to increasing fuel consumption, it will also increase carbon deposition and damage the three-way catalytic transfer and dispersion quiet changer. We should be in place for a minute or so and then we can be in gear, but at a low load.

2. But in fact, if the heat is not enough to reach the ideal temperature, the engine has to do extra work to generate more heat to meet the temperature requirements of the cab, which requires additional fuel consumption. The air conditioning compressor is not started, but the hot air from the engine tank is fed into the cab to heat the room. There is no additional energy consumption, and therefore no additional fuel consumption.

3. Many people are accustomed to heating up the car for the first time in the morning in winter, but if the car is heated in situ for a long time, it is actually very undesirable, in addition to increasing fuel consumption, it will also increase carbon deposition and damage the three-way catalytic converter. The correct way is to heat up the car in situ for about a minute, for example, the speed is stable, and you can be in gear on the road, but you need to check the low load of the mountain. Moreover, many cars are small displacement cars, the engine cylinder wall is relatively thin, and the cylinder is easy to lose high temperature, so in order to keep warm, so the fuel consumption will be more.

4. The signal of the water temperature sensor fails, and the sensor always provides information that the water temperature is too low to the ECU. At this time, the ECU will increase the opening of the idle valve, increase the amount of fuel injected, and thus increase fuel consumption. Engine start-up requires more fuel to be converted into electricity to charge the battery, so it is also a factor in increased fuel consumption.

If the spark plug is used for too long, the fuel consumption will also increase. Because the spark plug is damaged, the ignition energy decreases, and the car slows down, resulting in a significant increase in gasoline consumption.

5. The failure of the main valve of the thermostat leads to the failure of early opening, that is, the preheating time is too long or the engine temperature is too low. At this time, the computer will increase the amount of fuel injected according to the signal of the water temperature sensor, thereby increasing fuel consumption. When the owner has just started the car or is still warming the car, immediately turn on the heater, because the engine is not hot, and the cold wind blows in, which not only consumes electricity, but also increases the load of the engine and consumes oil.

Therefore, the increase in fuel consumption caused by low temperatures in winter is inevitable. If the vehicle does not have other phenomena such as jitter or faulty lights, it does not need to be repaired.

It may be because the temperature is relatively low in winter, it may also be because the quality of the engine is relatively high, or it may be because the frequency of the engine's hand slag is relatively strong, or it may be because the car needs to be warmed up in advance when driving, so the fuel consumption of the engine will suddenly increase.

This is because in winter, the weather is very cold, so when you start the car, it will heat up, and when you warm up, you will also consume a certain amount of fuel.

The reason is that the weather is colder in winter, so it usually consumes more fuel.

The sudden increase in fuel consumption from 9 to 14 may be due to the impact of engine carbon deposits.

The longer the engine works, the longer the carbon deposits in the engine will be excessive, which will greatly reduce the combustion power of the engine and increase fuel consumption.

1. Long-term engine idling. Idling in place for a long time makes it look like the engine is not revving high, giving people the feeling that it does not consume fuel. However, because the vehicle is not moving in place, all the time it takes for the vehicle computer to calculate the average fuel consumption will increase a lot.

In addition, if the engine is idle for a long time, because the fuel in the engine is not fully combusted, it will produce carbon deposits, and often in this case, the engine carbon deposits will increase significantly, making the fuel economy worse.

2. Sudden braking and rapid acceleration behavior. In the process of emergency acceleration, there is more fuel in the combustion chamber, less air, and the combustion chamber presents a state of hypoxia, and the fuel can not be fully combusted, producing a large number of hydrocarbons, and the resulting drag effect cancels out a part of the driving inertia, so it will also bring an increase in fuel consumption.

3. Frequent lane changes and non-standard driving. The vehicle consumes more fuel when cornering than when driving in a straight line because the drag increases when cornering, and the vehicle consumes more energy. Frequent lane changes, overtaking and merging, in addition to increasing fuel consumption.

1. The decrease in thermal efficiency leads to an increase in fuel injection.

Cars also need to maintain a certain temperature in winter to drive better. Especially in the engine, in a colder environment, the engine is easy to lose a part of the energy, and it needs to do extra work to maintain the normal operating temperature, so the engine can only maintain the temperature by increasing the amount of fuel injected.

2. In addition, in the low temperature environment, the viscosity of the engine lubricating oil increases, the fluidity and lubrication effect naturally decrease, and the working pressure of the internal parts of the engine will also be greatly increased, which also needs to be solved by increasing the amount of fuel injection.

3. After the cold car is started in winter, the in-situ hot car and the low-speed hot car need to consume a lot of energy. Some data show that the fuel consumption of the in-situ hot car is usually 3-4 times the normal fuel consumption, even if the cold car is driven for one or two kilometers, the vehicle fuel consumption is still about 2 times the usual fuel consumption, so the general in-situ hot car 2-4 minutes is enough.

Dear Kiss I am happy to serve you Car fuel consumption has increased from more than seven to more than eight o'clock in winter, this is normal, don't worry, this is not a failure. It is normal for all cars to have an increase in fuel consumption as they enter the winter season. The hot car time in winter is longer than other seasons, many car owners like to warm up the car for a long time in winter and then drive, no matter how necessary the hot car is, just talk about the gasoline consumption when the hot car, as well as the relatively low fuel utilization rate, is a lot of expenses!

It is recommended that car owners reduce the time it takes to warm up the car, about 30 seconds to 1 minute. The use of heat is not standardized, although the heating in the car in winter does not need to pay extra fuel, but when we use the heating air wrongly, such as when the vehicle has just started, although the water temperature seems to be normal, but the heat of the engine has not been fully generated, if the heating is turned on at this time, then the engine will have to do more work in advance, wasting more oil. Car owners are advised not to turn on the air conditioner prematurely.

The fuel consumption of motor vehicles in winter is about 15% higher than that in summer, because in winter motor vehicles consume more fuel, the internal wear and tear of the engine will increase. If you change your snow tires, the friction of your vehicle increases, resulting in an increase in fuel consumption.

How to effectively control the fuel consumption of the vehicle.

Control of motor vehicle fuel consumption. When a motor vehicle is moving, it is necessary to reduce the idle time. When the vehicle is moving, don't worry about the nuclear bridge.

Is the high fuel consumption of the vehicle a problem?

Excessive fuel consumption of motor vehicles is a problem, indicating that there is a problem with the motorized poor car. In this case, the motor vehicle needs to be repaired, the oil is checked regularly, and the engine of the vehicle is checked for not a small amount of carbon deposit. All of the above will have a certain impact.

Millions of car purchase subsidies.

**When it comes to the problem of fuel consumption, I don't know if your vehicle has high fuel consumption in winter or high fuel consumption in summer? Let's discuss it together.

If compared with the middle and lower reaches of the Yangtze River, the fuel consumption in summer is likely to be higher than in winter, and the air conditioning must be turned on in the summer without refrigeration, resulting in higher fuel consumption in summer; For the north, it is likely that the opposite is true, and fuel consumption is higher in winter. Many people are likely to be confused, originally the same driving, and the summer also applies air conditioning without refrigeration, why there will be a situation in North China where the fuel consumption of winter driving is higher than that of summer driving. So what's the deal with the high fuel consumption of the car in winter?

It is likely to be caused by the following reasons.

Reason 1: The decrease in thermal efficiency causes the ignition advance angle to increase.

In winter, because of the high viscosity of automobile oil and the low temperature of the automobile engine, the atomization of automobile gasoline is poor, which is equivalent to the discharge of some gasoline and diesel without complete ignition, and there is no conversion of reasonable work, so the automobile engine must increase the amount of gasoline and diesel injection in order to ensure the original power.

Reason 2: The warm air in the car causes the car engine to work extraordinarily.

Theoretically, the heater is not easy to run the compressor and simply sends heat from the engine tank into the cab of the car, which in turn warms up the house. On the surface, it seems that there is no additional energy consumption, and there is no additional fuel consumption. But in fact, if the heat flow is not enough to reach the set temperature, the car engine needs additional work to cause a large amount of energy, so as to give the car cab temperature regulations, then additional fuel consumption is required.

Reason 3: The hot train time is too long.

In winter, many people are accustomed to "hot cars" first, but if they stay in place for a long time to "heat up", it is actually very undesirable, in addition to increasing fuel consumption, it will also increase carbon deposits, damage to three-way catalytic converters, etc. Coastal areas are basically not prone to having to "heat up".

Reason 4: The water temperature sensor fails or the water temperature sensor does not work well.

High fuel consumption in winter.

1. The decrease in thermal efficiency leads to an increase in fuel injection. In winter, due to the high viscosity of the engine oil and the low temperature of the engine, the misatomization of gasoline is poor, which is equivalent to a part of the fuel being discharged without full combustion, and there is no effective work conversion, so the engine must increase the amount of fuel injection in order to ensure the original output power.

2. The hot air in the car causes the engine to do extra work. Theoretically, the hot air does not start the air conditioning compressor, but simply sends hot air from the engine tank into the cab, which heats up the room. If the water temperature is not sufficient in the cold start state, it is necessary to increase the water temperature by increasing the speed and thus consume more oil.

On the surface, it doesn't seem to have any additional energy consumption, and it doesn't consume extra fuel. But in fact, if the heat is not enough to reach the set temperature, the engine has to work extra to generate more heat to provide the cab temperature requirements, and then it will consume additional fuel.

3. The hot car time is too long. In winter, many people are accustomed to "hot up" first, because the temperature is low, so the hot car takes a long time. In addition to increasing fuel consumption, it will also increase carbon deposits and damage the three-way catalytic converter.

4. Tire pressure decreases. If the tire pressure in winter is lower than in summer, the air pressure in the tire will decrease, and the rolling resistance between the tire and the road surface will increase, and the fuel consumption will naturally increase.
