Why is the fuel consumption completely different for a car with the same engine displacement?

The first thing people look at when buying a car is how the fuel consumption of the car is, some cars have low fuel consumption, and some cars have high fuel consumption. But sometimes the fuel consumption of two cars that are exactly the same is very different, what is the reason for this? How can we use the car to save fuel?

Let's find out together.

In addition to the vehicle itself, the factors that affect the fuel consumption of a car are the following factors. The first is our driving habits, and good driving habits are the fundamental factor in saving fuel. Many car owners are in a hurry, often press the accelerator pedal sharply, and when the vehicle in front suddenly stops, they will press the brake pedal sharply, both of which are very fuel-intensive.

When we pressed the accelerator pedal sharply, although the speed of the car increased greatly, some of the fuel was discharged before it was completely burned. When we press the brake pedal hard, it also consumes a lot of fuel. Therefore, we need to drive predictively, maintain an appropriate speed, and press the brake pedal as little as possible during the driving process, so as to reduce fuel consumption.

Secondly, the condition of the car is also an important factor affecting fuel consumption, sometimes two identical cars, the use of the same is obviously the same, but the degree of fuel consumption is very different. If a car is using fully synthetic motor oil, it is enough to start cold and warm it up for half a minute in winter. If another car uses mineral oil, it takes about five minutes to warm up in the winter with a cold start.

Fully synthetic motor oil can reduce frictional resistance, improve the dynamic performance of the vehicle, and greatly save fuel. As a result, two identical cars will have different fuel consumption due to the use of different types of oil. Combining various factors, fully synthetic engine oil is much better than mineral engine oil, and the most important thing is to save fuel consumption, although it is slightly more expensive on **, but it is very practical.

The third factor that affects the fuel consumption of the car is the road condition, if the car often drives in the city with congested roads, due to the road congestion, the car is parked in place for a long time, and the engine is still working, at this time it will greatly consume fuel consumption. If the road is smooth, neither congested nor potholed, then the car's fuel consumption will be much lower.

So how do we usually use our cars to save fuel? First of all, the most important thing is to develop good driving habits, do not constantly bang the throttle, so that the engine speed is too high and cause fuel consumption to increase. Don't slam on the brakes too often, and drive predictably.

Secondly, the hot car time should not be too long, and the hot car time will consume fuel consumption if it is too long.

There is also a suitable temperature of the air conditioning in the car, generally at 24 degrees Celsius, not too low, as low as 18 degrees Celsius, which is very fuel-intensive. In addition, don't put too many things in the car, reducing the weight of the body can also reduce fuel consumption. However, the most important point is to choose the right oil to keep the engine lubricated and reduce fuel consumption.

We must always pay attention to our driving behavior in the daily driving process to reduce fuel consumption.

Why do the fuel consumption of the exact same car be different? What exactly causes it, listen to what the experts have to say.

The performance of the car is not an indicator of this, and fuel consumption can be affected by other factors, which should be measured in a comprehensive manner.

Because everyone's driving habits are different, plus the road conditions are also different. Therefore, the fuel consumption is completely different.

I think the fuel consumption of cars with the same displacement is not about the same, although some cars have a large displacement, but the fuel consumption is relatively small; I think there is a very big difference, how to operate in a different environment, the operator's action is different, or the engine and some parts in it are different, it will lead to different fuel consumption.

Of course not, if the displacement is the same, the fuel consumption of the car will be affected by other factors, such as the condition of the car, and the technology of the engine, there are certain differences.

It's not that the displacement is the same, the fuel consumption is the same; This side is very large, because fuel consumption is not only to look at the displacement, but also to see the quality of the car, the habits of the drivers.

The actual use of the owner of the model, as well as the fuel consumption test data of the model, etc. For many years, people often think that "small displacement vehicles are more fuel-efficient than large displacement vehicles", and this statement is theoretically a vertical truth, especially in the era when supercharging technology has not been widely used. But a closer analysis will reveal that this view is not absolutely correct.

In this article, we will briefly introduce the relationship between exhaust volume and fuel consumption and the main factors that affect fuel consumption. The three aspects of displacement, power and fuel consumption may seem similar, but many people don't really understand what displacement. To understand the relationship between exhaust volume and fuel consumption, we must first understand the concept of exhaust volume.

Displacement refers to the total volume of engine cylinders, including the working volume of one or more cylinders. It is generally expressed in liters (L). A larger cylinder volume can accommodate more combustible mixtures than a smaller displacement, so all else being equal, a larger displacement engine has better power and fuel consumption.

In addition to exhaust volume, factors such as tires, wind resistance, vehicle weight, drivetrain, and supercharging system can affect fuel consumption and power. Therefore, it is not accurate to judge the fuel consumption and power of a car based on the displacement alone. At the same time, the transmission shift logic, air intake system and fuel supply system also have an impact on fuel consumption.

Therefore, determining the fuel consumption level of a car requires a combination of multiple parameters, as well as an understanding of the actual usage of the car owner, relevant test data, and so on. In conclusion, displacement is an important factor affecting engine performance, but it is not the only one. Understanding the level of fuel consumption and power requires a combination of conditions.

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.

Summary. Hello. Friend.

The fuel consumption ratio is directly proportional to the engine speed, and the functional relationship between them is complex. The fuel consumption ratio is related to engine speed, load and a number of other factors.

Hope it helps.

What does the fuel consumption ratio have to do with the engine.

Hello. The fuel consumption ratio of friends is directly proportional to the speed of the motive of the trousers, and the functional relationship between them is very complicated. The fuel consumption ratio is related to engine speed, negative fluid load, and a number of other factors. Hope it helps.

I hope you can give me a thumbs up, your thumbs up are important to me, thank you.
