What kind of car is the most fuel efficient and what are the factors that affect fuel consumption

Hybridization, mainly the weight and engine, is also related to driving habits.

New energy vehicles are the most economical, and the fuel consumption is high because of the weight of the vehicle.

Tesla electric sports car you deserve it.

1. Long-term idling.

Fuel is also consumed when the engine of a car is idling. Generally, it takes more oil to idle a car for more than 1 minute than to start it again, and it is especially expensive to run an air conditioner when idling for a long time and idling. Excessive idle warm-up time not only wastes fuel, increases pollutant emissions, but also increases the risk of engine failure if the car is idling in place for more than 1 minute.

2. Low-gear high-speed driving.

There are some novice friends who drive manual transmission cars, because they do not handle the relationship between gear and speed and do not look at the tachometer, so they often step on the accelerator deeply when they are in low gear, and sometimes the engine speed even exceeds 3500 rpm, which is very fuel-intensive.

3. The clutch is semi-linked.

Some friends like to put their left foot on the clutch pedal for a long time after the car shifts, so that the clutch is in semi-linkage driving, thinking that as long as they don't use force, it will not have any effect. In fact, due to the uneven road surface caused by the bump of the car, the foot also shakes, which is likely to cause the clutch to be in a semi-linkage state.

4. Keep turning the steering wheel while driving.

Some friends always like to keep turning the steering wheel when driving, this kind of rotation is not the need for driving, but a conscious bad action. And the steering wheel is constantly turning, which will undoubtedly increase the rolling resistance of the tires. Curved driving also increases mileage, which naturally increases fuel consumption.

In addition, curved driving can increase tire wear and shorten the life of the tires.

5. Frequent lane changes and overtaking.

In the process of driving, some cars like to drill around in the traffic flow, when changing lanes, they must accelerate and decelerate frequently, and the fuel consumption must be higher than that when driving at a constant speed.

6. Speeding.

The speed limit on highways in China is 110 120 km per hour, and the speed of the car is 80 90 km per hour, which is an economic speed, but in fact, many people will exceed this speed. As a result, the engine provides much more power at high speeds than at medium speeds, and fuel consumption increases dramatically.

7. Drive with windows open at high speed.

Blowing through the windows on the highway will be more fuel-efficient than using an air conditioner, but that's a big mistake. We all know that the power required by the car to overcome the driving resistance is proportional to the cubic of the speed, so opening the windows when the car is driving at high speed will make the air resistance very large, exceeding the power required by the car air conditioner, and the car will increase fuel consumption more than the use of the car air conditioner.

8. Slam on the accelerator to accelerate.

Hard acceleration will increase fuel consumption by more than 30 compared with slow acceleration. Cars that often drive in urban areas have a lot of starts, and a lot of fuel will be saved if the starting acceleration is handled well.

9. Frequent sudden braking.

First, the road conditions of driving. Frequent stop-and-go, the engine combustion condition is only relatively poor, and frequent gear changes are often required. Fuel consumption is bound to increase.

Second, driving habits. Frequent violent driving, rapid acceleration, deceleration, and frequent lane changes are the main culprits of high fuel consumption.

There are many, for example, the car has been used for a long time, and then the weight of the car is heavier, the body is heavier than Lu Yin, and it is affected by wind resistance, and the old bench tires of the wheels are relatively wide.

Car displacement, car shape, when the road conditions are bad, the car stops and goes, the accelerator and brake switch back and forth, the weather is different, and the fuel consumption is also different.

Oil grade, cylinder pressure, fuel injection data, computer programming, air intake data, etc.

Pavement - the official test is to simulate the resistance of the car when driving on a straight and dry road, and is carried out on the chassis dynamometer in the laboratory, the friction resistance is stable, and there is no slope resistance; The actual user's vehicle usage is very different, the road surface and slope, the degree of dryness and wetness, and the fuel consumption of many car owners' vehicles are getting higher and higher. The price of oil is so expensive, and the number of kilometers you run with a full tank of fuel is getting less and less, but I don't know why. In fact, the fuel cost of the vehicle is related to the working condition of your car's parts and your driving habits.

It may also be the same as you.

The vehicle is in an idle state for a long time, such as idling to warm up the car in winter, idle for a long time in summer to turn on the air conditioner, and other factors such as the vehicle not turning off for a long time will lead to an increase in vehicle fuel consumption, and long-term idling, which will lead to an increase in engine carbon deposition and affect engine performance, you have to remember that if the tire pressure is too low, he will definitely increase the resistance of the vehicle in driving, so the fuel consumption will be high. So remember that the tires must be replenished. If you don't know how much to hit, go to the top of the fuel cap and take a look, it is clearly written.

Try to keep driving at a high level and avoid resisting high-speed driving. If you run 100 miles in 3rd gear, the fuel consumption will be ridiculous. Be sure to refer to the reasonable speed and gear of the vehicle to choose the right shift time, generally speaking, there are two aspects that affect fuel consumption, the first is driving habits, and the second is that there is a problem with the vehicle.

Let's talk about the first question first, driving habits are a big factor affecting fuel consumption, some car owners like to drive fast, and the fuel consumption will naturally go up when the speed is fast.

First of all, the most critical factor must be the technology of the car itself, the technologically advanced car, whether it is in the quality of the vehicle itself, or the shape of the car, or the thermal efficiency of the engine are relatively well-made, and these three are precisely related to the reason for the high fuel consumption of the car In addition to daily driving habits, whether the filter is often replaced is also very important, the role of the air filter is to ensure that the engine has sufficient air intake, so it is also very important to use high-quality air filter.

First of all, it is because the wrong gasoline is added or the efficiency of the engine is relatively low, or it may be because the weight of the car is relatively large, or the road is potholes or the wrong way of driving.

I know that the most common is the performance of the engine, the better the engine performance, the higher the fuel consumption.

The most common are environmental conditions, road conditions, driving conditions, air conditioning, and the number of passengers or the weight of the cargo.
