Can a small car really save money? Does a low fuel consumption car really save money

Generally, people who pursue high performance of automobiles mostly choose large-displacement engines, and people who attach importance to economy mostly choose small-displacement engines.

Displacement: The volume of space through which the piston moves from top dead center to bottom dead center is called cylinder displacement, if the engine has several cylinders, the sum of the working volumes of all cylinders is called engine displacement.

In China, the division of the sedan class is determined according to the size of the displacement. The displacement of the minicar is less than or equal to 1 0L; The displacement of ordinary cars is in the range of 1 0-1 6L; The displacement of the intermediate sedan is in the range of 1 6-2 5L; The displacement of mid-to-high-end sedans is within the range; The displacement of the premium sedan is more than 4 0 liters.

It is true that engines with large displacements are fuel-efficient, but this is only a characteristic of the engine.

In the car, the adaptability of the engine and the whole vehicle has a great impact on the economy of the car. If the adaptability of the engine with a small displacement is not good, it is likely that it will not be more fuel-efficient than the engine with a large displacement, and even more fuel-efficient than the engine with a large displacement. Especially for cars with heavy weight, if the displacement of the engine is too small, the use of small horses and large carts will inevitably make the engine run more at high speed and high load, thus consuming more gasoline.

In the case of a large-displacement engine, the amount of gasoline consumed does not change much because of the high torque and the need to press the accelerator pedal very deeply. In contrast, the result is likely to be that engines with smaller displacements are more fuel-intensive.

Generally speaking, this is true, but it is not absolute, it also depends on the powertrain, lightweight, wind resistance, driving habits, etc.

New cars can be added appropriately, but the proportion of cars that have driven more than 100,000 kilometers should be as small as possible. Otherwise, it is easy to cause car trembling and other situations.

Does a low fuel consumption car really save money

It is worth noting that it is not really meaningful to pay too much attention to fuel consumption, because when buying a car, the salesperson tells us that the fuel consumption value marked by the manufacturer, not the standard value. And the fuel consumption of cars of the same level is about the same, and it will not be too different. Even if one car saves a few liters of Lingling tour points compared to another car, it will save a few hundred dollars a year, and there is not much difference.

Also, instead of focusing on fuel consumption, it is better to develop better driving habits. The fuel consumption data we refer to is an average and is not representative of each vehicle. Moreover, the road conditions when driving and the driving habits of the owner will affect the fuel consumption of the car, especially when you frequently step on the brakes or slam on the oil bridge wang-shaped door when driving, it will increase the fuel consumption of the car.

There are also many people who will be attracted by the bells and whistles, which is not too necessary, and the vehicle is used as a substitute, not as a collector's item. Safety is the most important thing, and everything else is just the icing on the cake rather than the decisive factor. Many cars seem to be very smart, and even the most basic vehicle hardware configuration is very good.

There are also people who believe in the brand, and the brand is appropriate to refer to when buying a car, and to a certain extent, it can indeed be the quality of the car. But even if it is a different model of the same brand, the quality difference is very large.

It can be buried in defeat and take an effective and quick way to save money, and it is effective.

1. Reasonable selection of refueling time, generally in the early morning or evening refueling is the most cost-effective, because gasoline is also a liquid, considering the thermal expansion and contraction, the temperature in the early morning or evening is lower, the volume of gasoline will also shrink, and the overall temperature is higher at noon, the volume of gasoline will also be added with the increase in temperature, and we usually refuel according to the volume, not according to the amount of refueling, and early morning or evening refueling, the equal volume of oil is much more than noon, therefore, the choice of early morning or evening refueling is the most cost-effective.

2. The higher the gasoline grade, the better, even if it is a high-end car, it does not mean that it is necessary to add high standard oil. The higher the gasoline grade, the worse the natural ignition characteristics, and then the more fuel consumption, so the high grade gasoline for domestic vehicles with low displacement and low price is a waste of gasoline.

3. If you often drive in the urban area, not only more traffic lights, and commuting time, traffic jams are more coarse tea and light meals, the bottom of the car can not run, if the fuel tank is full, only the load of the car will be added, and the load of the engine will be added, and there are more gas stations in the urban area, and it is more convenient to refuel, and it is advocated that the owner can add up to two-thirds of the fuel tank when refueling.

4. If you find that the gas station is storing oil or the tanker truck has just left, do not refuel at this gas station. Because, when the tanker truck makes up the fuel for the gas station, it will wash up the deposits at the bottom of the fuel tank, and if you refuel at the moment, these deposits will be added to the fuel tank one by one, and these impurities will affect the service life of the engine.

The temperature of the underground storage tank of the petrol station is at its lowest from 5 a.m. to 8 a.m. (from 9:30 a.m. in summer to 9:30 a.m. (spring, autumn and winter), at this time, because gasoline is charged by volume rather than by weight, the volume will be affected by temperature. According to this principle, when refueling in the morning or evening, you can add a little more to the same liter of oil, which is also a great way to save money.

In the summer, refueling should be "seven points full; Many drivers will happily say "fill up" to the gas station staff when refueling, but this will not only increase fuel consumption, but also easily cause car body failure. Experiments have shown that for the same 1000 kilometers of travel, adding 10 kg of fuel in the car will increase fuel consumption by 400 ml, that is to say, the more you use, especially in summer, you should be "seven points full". As for the harm to the car body, the most common reaction is to cause the activated carbon tank to saturate or damage, some vehicles in the oil spillage, even will flow back to the rear seat under the oil pump installation plate, gasoline volatilization is easy to jump into the cab, so that the cab has a serious gasoline smell.

People often say that "it is easy to buy a car and difficult to maintain a car", and the annual maintenance cost of a car is not small, ranging from a few thousand to tens of thousands. No matter how to save this, fuel money is essential, and now oil prices are expensive, and fuel saving is a problem for large logarithmic car owners.

1. Su oil. Rush 1000 and get 100, basically every time you will give a car wash card. Su oil is not bad, near my home, near the 4S store, the card can be universal. It's a good deal for me. And there is no time limit.

2. Sinopec.

This can only be said to be better than nothing. Because milk is often out of stock, I have bought rice, and the quality is okay. Full discount coupons often expire and are only used occasionally. However, there are also coupons to give. The advantage of this is that it is close to the company, which is more convenient.

Summing up the top ten tricks for drinking oil in the car, if the owner implements it step by step, the car will save money and rest assured.

At the same time, be sure to keep the invoice, in case of an accident, this is the only evidence.

Cheap is not good", do not trust those so-called low-cost gasoline.

Because gasoline is charged by volume, not by weight, thermal expansion and cold contraction.

Because after rounding, money is often lost invisibly.

4. If you want to run a long distance, the more fresh oil, the more acceleration you will feel at high speed.

It is better not to fill up with high-grade gasoline.

In addition, you can also prepare some additives before departure, add a tank of oil can use a bottle of additives, after using additives, you can increase the label of the oil by one or two.

Depending on the location) because the urban traffic often stops and goes, if the fuel tank is filled, the load of the engine will be heavier, the start is weak and the vehicle consumes fuel, and many gas stations in the urban area are not afraid of having no place to refuel.

6. If the car is rarely driven, it is recommended to keep the oil level at a low level.

Because gasoline will deteriorate after a long time.

This is because when the oil is filled, it is easy to volatilize into the atmosphere and cause air pollution, which not only causes waste, but also causes harm to the air, and may also damage the engine or catalytic converter.

Because the fuel replenished by the tanker truck will gush up the sediment at the bottom of the tank for many years, it is very likely to be added to the tank.

Because gasoline is stored underground, there may be some leakage over time, and after a rainstorm, rainwater that cannot be discharged may leak into the oil tank.

10. Use whatever label of gasoline should be used.

Don't blindly worship high grades, this will also save a lot of silver.

It is said that gasoline is affected by temperature, and the volume shrinks and expands very much, so some people go to refuel late at night or early in the morning; Second, add half a tank of fuel to it, do not fill up, save the car load and fuel consumption, always walk in the city, refueling is very convenient. It is best to fill up the high-speed run in other places, which saves trouble; Third, when driving, refuel slowly, and release the accelerator before the intersection and slowly slip over; Try to minimize the need for refueling and braking suddenly, because this will turn the added gasoline on the wheel hub or brake disc into another kind of heat. Try to get out of the car what you don't use.

In addition, it is generally believed that fuel-efficient models can also be selected.

With the gradual improvement of family conditions, every household is driving. So how do you drive fuel? What are the fuel-saving technologies?

First, don't be in a hurry when driving, don't step on the accelerator and brake suddenly, which is unsafe and fuel-intensive. So when driving, we try to press the accelerator lightly and use the brakes as little as possible.

When encountering traffic lights, it is necessary to slow down the throttle in advance, try to use less speed control, and the rubber belt vehicle gradually decelerates to the parking space, saving car fuel and making it more comfortable.

Third, try to keep driving at a constant speed, driving fifty or sixty yards in the urban area is just right, look at the local Liang Nianlu speed limit, the most fuel-efficient highway is 120 kilometers per hour, but pay attention to safety, the line can be allowed.

Finally, car choice is also important, because we all talk about knowing that Japanese cars are more fuel-efficient, lighter, more expensive, and heavier.

What kind of car are you driving? What about fuel consumption, and what are the more fuel-efficient technologies? Annotations can be shared with everyone!
