Why do some people drive the same car to save fuel and some people drive it very fuel intensively?

We know that there are many factors that affect the fuel consumption of a car. First of all, when the car environment is different, the fuel consumption is also different. If the vehicle is often driven at high speeds, then the fuel consumption will be relatively small.

Vehicles are usually driving in the city, and often encounter traffic congestion and frequent start and stop, which will lead to increased fuel consumption.

Secondly, everyone has different driving habits. Some people like to drive cars intensely, and they often press the accelerator and brake hard during driving, so that the fuel consumption is relatively high. Some people are accustomed to driving at a constant speed and prefer to use the accelerator to control the speed, so that driving is naturally more fuel-efficient.

In addition, the driver's driving skills also affect the fuel consumption of the car. Some veteran drivers drive all year round, have rich driving experience, and have a stable mentality, they know how to drive fast and ensure low fuel consumption. People with average driving skills don't understand these skills, and the fuel consumption of driving is relatively high.

Therefore, we not only need to maintain correct driving habits when driving, but also slowly accumulate more experience, so as to reduce the fuel consumption of the car as much as possible.

Because everyone's driving habits are different, different road conditions and the severity of stepping on the accelerator will affect the fuel consumption of a car, such as driving smoothly at high speed and thus fuel consumption is relatively low, if you give a floor oil on the non-paved road, this is the fuel consumption will be greatly increased, and another is the maintenance of the car, replacing the oil, spark plugs and regularly cleaning the engine carbon deposits will affect the fuel consumption performance of the car.

It doesn't matter if you are an American, German, or Japanese car; Or luxury cars, economy cars, everyone is actually concerned about fuel consumption. So what are the factors that cause the severe fuel consumption?

Insufficient tire pressure.

Let's talk about some more ordinary ones first, for example, the tire pressure of your tire often doesn't matter, it doesn't matter if it is deflated, and it doesn't matter if the gas is too full, that will affect fuel consumption.

It's exactly the same as when we ride a bicycle ourselves, when we run out of gas, we will be tired to death, and that's tire pressure.

Failure to maintain on time.

If we do not maintain it in a timely manner, the three filters in the car: oil filter, air filter and gasoline filter, these three things are not replaced in a timely manner, it will also have a great impact on our fuel consumption.

Heavy objects are placed in the trunk.

And then there's the brainless often putting things in the car that you don't need, which is equivalent to not being able to get along with your wallet. In addition to useful things such as spare tires and car toolboxes, other things that are not used should be freed up in the trunk as much as possible.

The engine control unit is damaged.

In addition, in the case of damage to the engine control unit, it will also cause abnormal fuel consumption. However, for new cars or cars within 100,000 kilometers, the occurrence rate of such problems is not very large.

Because of the different driving styles, some people like to drive violently and step on the accelerator to the end, which not only consumes fuel, but also hurts the engine.

Personally, I think it's because the guy who drives the car doesn't know how to drive, and he does a lot of damage to the car itself.

Because everyone's driving habits are different, the fuel consumption of these cars is different.

Introduction: The problem of fuel economy is a topic that many people are very concerned about, so is the vehicle more fuel-efficient the more it drives, or the more fuel-efficient it is? On what basis? <>

There are many people who may feel that when they first pick up a new car, they are very fuel-efficient, but when they drive it, they consume fuel. So is the more the vehicle is driven and the more fuel is consumed, or the more it is driven, the more fuel-efficient it is? Under normal circumstances, the car must be driven more and more fuel-intensive, because in the process of using the car, some parts have been aged, and after a long time, there will be fuel consumption.

And in the process of driving, there may be some carbon deposits in the car.

If you don't clean it up in time, you may also feel that the more you drive, the more fuel you consume. <>

In fact, there are many reasons that affect the fuel consumption of automobiles, and there are some vehicles with heavier bodies, which are also more fuel-intensive in the process of driving, because the car is heavier, so it needs more power. Tire pressure.

When there is a shortage, or when the tires are worn, it can also be very fuel-intensive. In this case, the drag of the car is increased, and the fuel consumption is also increased. Long-term unstable idling will also increase the fuel consumption of the car.

There are also some bad driving habits that can also increase the fuel consumption of the car. <>

If we want to make the car fuel-efficient, we must drive at a constant speed. At the same time, it is also necessary to check the tire and tire pressure regularly, so that you can also save some fuel consumption. When we come to drive, we don't slam on the accelerator, because when we press the accelerator, the fuel consumption will increase, and at the same time, it will cause some damage to the engine.

When we want to save fuel in our car, we can try not to go through some congested road sections, and prolonged braking and starting will also increase the fuel consumption of the car. If you want to save fuel, don't open the windows of your car when driving at high speeds.

Generally, the more vehicles are driven, the more fuel is consumed; Because in the process of driving the vehicle, some parts will age, and some parts are not cleaned in time, there will be carbon deposits, which will cause the vehicle to become more and more waste oil.

The more you drive, the more waste oil, because the car has been driving for a long time, the fuel consumption will become higher and higher, the sensor will age, the tire wear is particularly serious, the spark plug has serious quality problems, and the tire pressure is relatively low.

1. When the car drives to 60,000 or 80,000 kilometers, the spark plug must be replaced (no matter what brand of spark plug it is), because if it is not replaced, it will lead to an increase in fuel consumption, and the start will be slower, and even the exhaust pipe will emit black smoke.

2. Check the oxygen sensor, replace or remove it in time, put it in the toilet cleaner, soak it for 5-8 minutes, and install it after the carbon deposit is removed.

3. If there is an obvious smell of gasoline in the car, you should replace the activated carbon canister in time and go to the auto parts city to buy one.

Of course, the more you drive, the more fuel-efficient. Because when the run-in degree with the vehicle reaches a certain standard, you will know your car very well, and you will also know more about some parts of the car, and you will also understand how the car is more fuel-efficient, so you will drive more and more fuel-efficient.

The more you drive, the more fuel you consume, because the vehicle will age after a long period of use, some parts have some problems, and sometimes the car will be more low-carbon.

The more the car is driven, the more fuel is consumed, because after the car is driven for a long time, some parts of the car and the engine will be damaged, and the fuel consumption will become greater and greater.

First of all, the fuel cost should be considered from several aspects, and the run-in period of the new car.

At the beginning, it costs oil, because there is no normal gap between the parts, and the running resistance between the parts is large, and the more you drive during this period, the more fuel-efficient, within 7500. Normal service period, during which regular maintenance and maintenance, so that the vehicle as much as possible to restore the new car state, the vehicle's four oil and one water, engine oil transmission.

Oil, brake fluid, steering assist fluid.

Decadence period After 150,000 kilometers, the fatigue period is entered as the parts of the vehicle run for a long time, and the gap caused by wear and tear becomes larger and the sealing becomes poorer, and the more you drive, the more fuel is consumed. It is true that the fuel consumption of the new car will be higher in the first period of driving, because the car is still in the run-in stage, including the engine and gearbox.

The brakes and even the tires are still there, and it cannot be said that the best work match has been achieved. And because people are not familiar enough with the car, the car will indeed cost a little more fuel in the early stage. Generally speaking, after the run-in period or the first insurance, or after driving 3000 kilometers, fuel consumption will decrease.

However, it must be said that it is extremely inaccurate to judge fuel economy simply by the age and mileage of the car. The fuel economy of the car is a process influenced by "innate + acquired", in other words, it is related to the powertrain.

The innate genes have a lot to do with it, and it is also related to the later use.

The innate genes of the power system refer to the fuel-saving characteristics of the engine and gearbox, and the fuel-saving characteristics of the drive system. There are a lot of technologies involved, such as Mazda.

The SPCCI technology is based on the principle of homogeneous compression ignition, which pushes the combustion efficiency very high; Or the cylinder closure technology, according to the different use states of the engine, to adjust the number of cylinders used, etc. The transmission system will be relatively easier to distinguish, such as the manual transmission in various transmissions.

It is the easiest to make low fuel consumption performance. In addition, four-wheel drive.

It is also common to spend more fuel than two-wheel drive.

As for the influence of the day after tomorrow, there are a lot of rents. For example, if you don't take good care of your car, you can accumulate carbon.

more, the car must be driven more and more fuel-intensive. However, if properly maintained, the fuel consumption performance of the car will often show a "U" shaped change trend. That is, the initial oil consumption, the mid-term sensitive type of smart oil, and the later stage back to the oil consumption.

As for why it costs oil in the later stage, this is because the auto parts themselves have been aged, and they cannot be reversed by maintenance.

Generally speaking, the more the liquid difference opens, the more oil is consumed; In the process of driving, there may be some low-carbon phenomena in the process of driving, and if it is not cleaned up in time, the car will become more and more fuel-intensive, and the vehicle will also experience some wear and tear in the process of driving, and when the vehicle parts are old, it will also increase fuel consumption.

The more you drive, the more fuel you consume. Because the engine will accumulate carbon after driving for a long time, which will lead to increased fuel consumption.

Generally speaking, the more the vehicle is lacking, the more fuel is lost; Because after driving for a period of time, the engine and brakes will have a certain amount of wear, and the car is likely to have carbon deposits, and the fuel volume will increase in the process of changing islands or driving.

<> "Cars are becoming more and more fuel-intensive, and it is because of this!"

No matter what it is, there will always be problems after using it for a long time. The same is true for cars, after the car has been driven for a long time, the owner will find that the car is more and more fuel hungry. How can a car be driven with such fuel consumption?

So why is it that after a long time, cars are becoming more and more fuel-intensive, and how should this problem be solved? I'm going to explain it to you today.

1. The car is overloaded.

A large reason for the increase in car fuel consumption is because the car is overloaded. Some cars are used to run construction sites and need to carry a lot of things. And some people are used to solicit customers, and sometimes they continue to stuff people into the car when it is full.

Over time, it will cause the fuel consumption of the car to increase, and the wear and tear of the cylinder will increase. The solution to this problem is also very simple, that is, just don't overload, and then clean the trunk of the car frequently to reduce the burden on the car.

Second, the quality of gasoline is not good.

In order to save money, some people use some poor-quality gasoline. In fact, it is a waste of money. Because poor quality gasoline will increase the carbon deposition of the engine, which will lead to an increase in fuel consumption, the fuel consumption will rise, and the number of refueling will also increase, which will cost money.

It is also very simple to solve this problem, which is to use *** gasoline, so that the car will not drive more and more fuel.

3. Replace the battery for a long time without lead.

The battery of the car is an important part of the car, which controls the circuit in the car, and the circuit and the oil circuit are closely related. If the battery is used for too long, there will be a loss of power, and the power of the car engine will not work, so the fuel consumption will naturally rise. Therefore, we should replace the battery regularly, preferably in less than two years.

Fourth, the air filter is blocked.

If the car's air cleaner is clogged, then the car's air intake system will be greatly affected. Not only that, but the wear and tear of the car's engine will also be very large, and the fuel consumption of the car will also increase. Therefore, we have to regularly check whether the air filter of the car is blocked, and replace it after driving less than 20,000 kilometers.

Fifth, the fuel injector is seriously blocked.

The fuel injector of the car is also a very important part of the car, and many people will ignore the maintenance and replacement of the fuel injector. In fact, the car fuel injector is very important, if there is a problem with the oil quality in the fuel injector, it will cause its carbon deposition to be serious and can not work normally, so that the car will slow down and the fuel consumption will rise. Therefore, we need to clean the fuel injectors of the car frequently and replace them regularly.

There must be a reason for the increase in car fuel consumption, and we must pay attention to the usual maintenance of the car. If the fuel consumption of the car has risen, you can take a look at the parts of the car I said if there is a problem, if so, you must deal with it in time, otherwise the car will consume more and more serious fuel.

Many friends will ask us if we need to spend more money to buy a large displacement model when buying a car, because everyone has heard that large displacement models not only have good power when driving at high speeds, but also have low fuel consumption. But why are large-displacement models more fuel-efficient at high speeds? Because this involves the concept of engine torque, because torque determines how fast the car accelerates, and power determines the speed of the car!

This is the torque and power output curve of a self-priming engine) Take Mazda Artez as an example, which is a representative model of self-priming models.

Atez's engine has a maximum torque of 252 Nm and can output at 3250 rpm, with a maximum power of 192 hp at 6100 rpm! This is the characteristic of a self-priming engine. I'm majoring in automotive, so I'll be happy to answer your questions.

Suppose there are two cars of the same quality, both of which are small displacement and large displacement, so that the same mass of the car must output the same power at the same speed (kinetic energy theorem), but the engine torque of the small displacement is insufficient (because of the limited fuel burning capacity, the total volume is small, the small cylinder intake is less, and the fuel injection (except for the turbine)), the high power output can only be achieved by increasing the transmission ratio of the gearbox, that is, high speed.

The engine with a large displacement has a strong ability to burn oil and can obtain high torque at low speeds, so it matches the high-speed gear with a small transmission ratio, so the speed decreases. Both output the same amount of power, but the smaller displacement had to be achieved at higher speeds, which meant more friction between the piston and the cylinder wall per unit of time, and more oil had to be injected to overcome the friction.

The large displacement speed is low and the friction work is small, so the relative fuel consumption is also less, but it is also limited. This is not only reflected in the fast full load or air conditioning in the Sparrow segment, but also in my personal opinion, large displacement cars should be more durable, since the engine speed rarely exceeds 2000 rpm. The basic number of steps for a small displacement is 2500 to 3000.

If the same path is taken, the wear and tear of the engine will be even worse. The throttle only needs to be lightly clicked, and the speed goes up, and the small displacement to achieve the same high speed, you must step on the throttle, and the fuel consumption will naturally go up.
