What is the relationship between displacement and fuel consumption? Does a car with a large displace

Generally speaking, the larger the displacement, the higher the fuel consumption per 100 kilometers, but there is no formula between the two, at least the driver's control point is impossible to formula.

The following factors can be used as a relatively large weight as a reference for fuel consumption:

Displacement, curb weight, full load mass, actual engine speed, output torque), road conditions can be reflected by the real-time parameters of the engine.

There are many others, such as wind resistance (which affects when the speed is very high), tires, etc. But the most difficult to quantify, in addition to the human driving factor, is also the assembly process, which is the key to testing the comprehensive strength of the manufacturer.

The same bearing, the same fit, different assembly methods, the results are very different, and the process control leads to very different final results.

Displacement has a lot to do with fuel consumption, and the fuel consumption of a car with a large displacement is not necessarily more than 100 kilometers!

Running at high speed with a small displacement consumes more fuel, and it saves fuel when running in urban areas.

Running at high speed with large displacement saves fuel, and consuming fuel when running in urban areas.

But there are also special ones, such as the Nissan VQ35 engine displacement but the actual fuel consumption of about 11 liters per 100 kilometers.

That's for sure. Large displacement must have high fuel consumption, but it does not mean that high fuel consumption must be due to displacement, road conditions, driving habits, and car conditions, but these are only increased or decreased in the normal fuel consumption base position, but the fuel consumption base value is still determined by displacement.

There is a big relationship between displacement and fuel consumption. However, it is not entirely linear. It is also related to the driver's driving habits and the performance of the vehicle itself.

For example, when a BMW 12-cylinder car is driving in the city, the driving computer will adjust the work according to the actual situation, so that the fuel consumption of the vehicle is only half of the label.

1.Vehicle displacement affects fuel consumption, but it is a decisive factor. In other words, the larger the displacement, the higher the fuel consumption per 100 kilometers.

High fuel consumption. Comparatively speaking, the displacement of a car is directly proportional to its consumption. The fuel consumption of a car is not only related to displacement, but also to shape, dead weight, engine technology.

2.The more advanced the engine technology of the same displacement model, the more fuel-efficient the car is. This engine technology is embodied in variable valve timing valve systems (VVT), adequate valves, wheeled supercharged engines, etc.

3.Attached: Advantages of small displacement cars:

4.Energy saving: 5Compared with family economic cars, fuel consumption is basically per kilometer, 100 kilometers of fuel saving, and the social benefits are very obvious.

6.Environmental Protection:

7.China's urban ambient air quality monitoring shows that with the rapid increase in the number of urban motor vehicles, motor vehicle pollution has become a source of air pollution in many cities.

8.Economy: 9Small displacement cars are the best city cars, cheap, and within the family's financial affordability.

Car displacement is one of the factors that harm fuel consumption, generally speaking, the larger the car displacement, the fuel consumption.

Fuel consumption is also affected by factors such as driving habits, driving roads, vehicle load, tire pressure standards and climate. Fuel consumption displacement of general displacement: 100 kilometers for manual models 4L, 100 kilometers for automatic models; Displacement:

5L for 100 kilometers for manual models, 6-7L for 100 kilometers for automatic models; Displacement: 100 km for manual models, 6-7L for 100 km for automatic models; Displacement: 7L around 100 kilometers for manual models.

Over the years, everyone's living economy has been much better, it can be said that six or seven out of ten people have cars, and the most important thing to drive is the fuel problem of the car, after all, the car is used every day, and refueling is also going to go once every few days, and a large part of the money earned by many people every month is used to refuel. But there are many people who also find a problem, that is, their own car is, but the fuel consumption of friends is even lower, so they really can't think of what is going on, so do you know what the reason is?

In fact, we must first know what is the difference between the displacement of the car and the fuel consumption of the car, as long as we figure it out, it will feel very simple. In fact, we can all find a problem, that is, the small displacement is generally matched with a small car, although the smaller the displacement, the more the body, but if your car is relatively large, then the use of a small displacement engine, then it will become very expensive, so each displacement of the car has a corresponding size of the car, otherwise the fuel consumption of the car will become very unreasonable.

In fact, the relationship between the engine and fuel consumption is very simple, for example, an engine, when its speed reaches 4,000 rpm, its torque is the most powerful, but normal people will not let the car exceed 3,000 rpm, so the torque of the car can only use 130 Nm, and the greater the torque of the car, the stronger the power of the car, so the displacement fuel consumption of each car depends on the size of the car.

In addition to the size, the rest is the weight of the car, a normal car is about 1500 kg, and a car needs 140 Nm of torque to drive him, so when the engine reaches 4,000 rpm, the fuel injection of the fuel injector will increase a lot, and the working state will become more frequent, so at this time the fuel consumption of the car is also rubbing towards the first. The advantage of the engine is that the required torque can be easily achieved at low revs, so of course they have a lower fuel consumption.

However, this is when running at high speed, in fact, if you are driving in the city, the normal car is not comparable with the car, at this time the fuel consumption of the small displacement must be relatively low, after all, the weight of the large displacement car itself is relatively large, so the comprehensive fuel consumption, the urban area or the small displacement car is more advantageous.

So after reading the above analysis, how do you think you need to buy a car? In fact, if you often use it to and from work, then it is recommended to use a small displacement car, after all, the way to and from work is stop-and-go, but if you often go at high speed, then a large displacement car is more suitable, after all, a large displacement car is more abundant, and overtaking is more rapid.

In a relative sense, the size of the car's displacement is not proportional to the size of the fuel consumption, for example, the same 4-liter displacement of the car, the fuel consumption is not necessarily equal. But in an absolute sense, a car with a large displacement will definitely consume more fuel than a car with a lower displacement. For example, within 100 kilometers, a 4-liter car will definitely consume more fuel than a 1-liter car.

There is a relationship, generally the larger the displacement, the greater the fuel consumption of the car.

Generally speaking, the larger the displacement, the more fuel will be consumed.

Generally speaking, the larger the displacement, the higher the fuel consumption per 100 kilometers. However, there is no clear proportional relationship between the two.

If the car has a large displacement, will the fuel consumption be high? What is the relationship between car displacement and fuel consumption? Make no mistake.

As we all know, the stability and driving control of a wide tire are much better than that of a narrow tire, but it also has a large friction with the ground, and the rolling resistance to the car is correspondingly large, and its fuel consumption is naturally more than that of a narrow tire car.

The larger the displacement, the greater the fuel consumption.

There is no necessary relationship between displacement and fuel consumption, but there is a certain relationship.

It's okay, these are two different functional areas of the car.

High fuel consumption may not only be the horsepower of the car, but also the car is too old and the engine is aging and causes too much oyster sauce.

Vehicle displacement is one of the factors that affect fuel consumption. Generally speaking, the larger the displacement of the vehicle, the more fuel it consumes. In addition, fuel consumption is also affected by personal driving habits, driving sections, vehicle load, tire pressure, weather and other factors.

Fuel consumption of normal displacement.

Displacement: about 4L per 100 kilometers for manual transmission models; automatic vehicles per 100 km;

Displacement: 5 liters for manual transmission and 6-7l for automatic transmission.

Displacement: manual transmission models per 100 kilometers about, automatic transmission models about 6-7L per 100 kilometers;

Displacement: 7L per 100 km for manual transmission models, 8-9L per 100 km for automatic transmission models;

Displacement: 7-8L per 100 km for manual transmission models, 9-10L per 100 km for automatic transmission models;

Displacement: about 9L, 11-12L for manual transmission models; For automatic models;

Displacement: manual transmission model about 12L, 13-15L; For automatic models;

The shape of the car is also related to fuel consumption.

Generally speaking, the drag coefficient of the sharp car is smaller, and it is relatively fuel-efficient. It is worth noting that the popular wide front face design is not conducive to fuel economy, but the large grille increases the air intakes, and the wind noise is relatively low, so the comfort is higher.

In addition, if the owner frequently refuels or applies the brakes, the fuel consumption is comparatively much higher. Moreover, often driving in congested or bad road conditions will not only accelerate engine wear, but also increase fuel consumption. It has been scientifically proven that 80 km/h is the most fuel-efficient speed.

Therefore, it is necessary to have good driving habits and maintain a constant speed on better roads, which will be more fuel-efficient.
