Why are gasoline models more fuel efficient on highways?

First of all,The powertrain used in gasoline and electric vehicles is different, resulting in differences in their economy under different road conditions. For pure electric vehicles, the generator directly drives the transmission system to start the car, and the current is proportional to the speed of the car. And for fuel models, <>

The engine needs to reach a certain speed when starting, and the fuel consumption of the car is relatively high when the speed is increased. Especially in some urban areas or on low-speed roads, there are more traffic lights, and the car needs to stop and go, and frequent starts and speed increases will naturally make fuel consumption higher. <>

theSecond, for fuel vehicles, the engine has one of the most economical fuel zone speedsWithin this speed range, the energy conversion efficiency of fuel vehicles is relatively high. This speed is determined according to the characteristics of the engine, which means that the economy of different engines is in different fuel speed ranges, and only controlling the speed within a specific range is the best way to save fuel.

On the highway, the speed and speed will not change frequently, and it is easier to control, so it is easier for fuel vehicles to reach the most economical speed, and the natural fuel consumption is relatively low. <>

mostFinally, for electric vehicles, the wind resistance that needs to be overcome at low speeds is also relatively smallIn addition, at this time, the electric vehicle can carry out a certain degree of kinetic energy**, will not feel strong resistance, and the power output is relatively smooth. However, in the case of high-speed driving, the wind resistance will increase exponentially, and the electric vehicle needs to use more power to fight the wind resistance, and the natural range will also decrease.

Although fuel vehicles will also face the problem of wind resistance, they will not have a great impact on fuel vehicles due to their high carrying energy.

Because you can play freely on the highway, this can reduce a lot of fuel consumption.

The generator directly drives the drivetrain to start the car, and the current is proportional to the speed of the car, and the faster the car, the greater the current required, and the power consumption will be greatly increased.

, resulting in differences in their economy under different road conditions. In the case of BEVs, the drivetrain is driven directly by a generator to start the car.

Fuel vehicles and other power models. There is a big difference in terms of fuel consumption.

Because it keeps walking, it doesn't stop, and it doesn't consume any other amount of oil during the period.

The faster the car, the more current it needs, and the more power it consumes.

The amount of current is directly proportional to the speed of the car, and the faster the car, the greater the current required, and the power consumption will be greatly increased.

Fuel efficient.

The so-called economic speed refers to the most fuel-efficient driving speed of the car, due to the different power combinations of each car, the economic speed is also different, usually the economic speed of most cars is between 80-110, when the speed is lower or higher than this economic speed, fuel consumption will rise.

Generally, if these small displacement cars want to achieve the best fuel-saving state, then the best speed must be kept within 2000, so that the fuel consumption can also reach the minimum, converted to speed, that is, between 70 and 80, the reason why there will be floating, of course, is related to the difference in the displacement of some models.

Precautions for running at high speeds.

Greening trees in the highway ** separation zone.

It is generally very high, if you take the left lane for a long time, you will not be able to see the oncoming road conditions, in case of extreme circumstances, there is a vehicle on the opposite side of the road out of control and break through the guardrail, the consequences will be very serious.

In addition, driving next to a tall barrier for a long time will be particularly depressing, and you will have the illusion of leaning up. And in the leftmost lane, once you encounter danger, you can only dodge to the right, because the left side is the separation zone, and when you take the right lane, you can avoid danger on the left and right, and there is more room for maneuver.

The economic speed of the car is about 80 kilometers per hour, and the 110 kilometers per hour on the highway has exceeded the economic speed, at this time the displacement, wind resistance and other factors of the car may lead to fuel consumption higher than the economic speed, you can try to reduce the speed of running at high speed, such as running 90 or 100 or so, at this time the fuel consumption will be significantly down. Because the closer you get to the economical speed, the lower the fuel consumption.

Fuel is saved within a certain speed, and fuel is consumed if the speed is exceeded.

Because the highway can change the throttle infrequently, it can avoid too many braking and gear shifts, and the speed is the same at a constant speed, which is more fuel-efficient than the urban area; However, if the speed is too high, such as running at a constant speed of more than 120, it will cost a lot of fuel compared to a uniform speed of 80-90.

If you run at high speeds, whether it is a manual transmission or an automatic transmission that is fuel-efficient.

Running at high speed is at a constant speed, which is more fuel-efficient than usual.

The vehicle consumes more fuel at high speeds, and in the final analysis, it boils down to one sentence: the wind resistance becomes larger.

Car engines.

has its own characteristics, its thermal efficiency.

It is not constant, and its thermal efficiency is highest at high load and low speed; At low loads and low speeds, the thermal efficiency of the engine will be less than half of the most effective time. on city roads.

The vehicle is often under the conditions of low speed, small throttle, or even high speed and low energy conversion efficiency, and the fuel consumption is high; On the highway, thermal efficiency is higher (when speed is economical) and shows higher fuel efficiency. If the speed is doubled, according to the drag calculation formula, the drag will increase by 4 times, and the engine is used to overcome the air resistance.

The "waste" is that the more fuel consumption, of course, will also increase.

So how can we reduce fuel consumption? Here are a few things for car owners to choose from.

1.The resistance mainly includes the vehicle's wheel rolling resistance, air resistance and acceleration resistance, and ramp resistance. When buying a car, you should choose the frontal shape optimization and the frontal projection area.

A model with a small drag coefficient. The drag coefficient of an SUV is not ideal, and it is greater than that of a sedan. In urban traffic, the speed is low, and the difference between the drag coefficient of the car and the SUV has little effect, and once the highway is on the highway, the fuel consumption of the sports utility vehicle will soar.

Therefore, from the economic aspect, it is not recommended that car owners often run at high speeds to buy SUV models.

2.The weight of the vehicle is proportional to the fuel consumption of the vehicle. Therefore, it is necessary to minimize the load on the vehicle while driving and reduce the weight of the vehicle.

3.To control the optimal driving speed of the car, the engine speed of the general EFI car is about 2200-2500. No matter what gear you're in.

Keeping the engine rpm at 2200-2500 is best. Driving in fuel-guzzling aisles at low speeds can also damage the engine; And increasing the ineffective rpm can also hurt the engine. The most fuel-efficient driving state is driving in a straight line at a constant speed, and the most fuel-efficient speed of a small engine car is 60-80 kilometers per hour.

Because the optimal fuel efficiency speed for each car is different, it may be that your car is more fuel-efficient at low speeds, so the fuel consumption is greater.

The reason why small displacement sometimes costs fuel is that the output torque of the small displacement engine is small, and in order to maintain the power of the vehicle, it is necessary to maintain a certain high speed, so that the engine can be maintained at a relatively high speed for a long time, which consumes fuel; Moreover, due to the cost, the engine technology used in the small displacement engine is relatively low-level, which will also affect the fuel consumption rate level of the engine. Large-displacement vehicles do not have to maintain high rpm because of the high engine output torque, so they can save fuel.

Because the wind resistance becomes larger, the load is higher and the speed is higher when driving against the wind, so the fuel consumption is greater.

Because the wind resistance becomes larger, the car will be very fuel-intensive, and the less resistance to driving, the more fuel-efficient the car will be.

First of all, the high-speed is generally smoother than the family digging, there will be no stop-and-go frequent start and brake waste of fuel, the vehicle has been kept in the high grade, and the engine is kept running in the best working condition (that is, in the best thermal efficiency.

range of speeds near the range), high speed is relatively fuel-efficient. But not all cars with a speed of 120 km/h are the most economical. It also depends on the combination of displacement weight and different speeds.

In general, liters and below vans such as 5-speed transmission.

The economic speed is 50 to 60 per hour, running at a high speed of 120 but it costs fuel, to the displacement of ordinary family cars such as 5 or 6 gears of transmission for 80 to 90 per hour, to the liter of 8 or 9 gears, 120 per hour is the most fuel-efficient (this is also divided into cars or SUVs, SUVs have large wind resistance, doubling resistance is too fast and fuel consumption). In fact, the answer is right, for some models do not necessarily have to go on the highway, as long as the road is the truth, such as the highway without traffic lights and never stop-and-go national highways are the most fuel-efficient. Because there is no minimum or maximum speed limit, you can choose to maintain your speed according to your car.

Like a liter van, you let it run all the way for 120 km, all the way for 60 km. It is estimated that it will take twice as much fuel to run 1000 kilometers, and when the cost of car oil is high, the answer must be to start and get off the road, so why are cars on city roads.

On the high cost of fuel consumption, mainly in urban areas to wait for traffic lights, avoid pedestrians, often have to brake, then start, and then open, which directly leads to the rise of fuel consumption. I have driven 7 cars, from Changhe River to Guandao, driving for 16 years, covering more than 1 million kilometers. I can tell you responsibly that the high-speed 120 is not fuel-efficient.

Qoros. Speed 100 per hour, fuel consumption or so, 120, fuel consumption or so, EGGER speed 90, fuel consumption, 120, fuel consumption or so, Cruze speed 100 per hour, fuel consumption or so, 120 per hour, fuel consumption or so. At the end of the day, fuel consumption is not about speed, but about vehicle displacement, wind resistance, gearbox.

matching, highway conditions, etc. And adaptive cruise.

It's definitely not fuel-efficient, at least one more than human-controlled, because of the acceleration of adaptive cruise.

Too big. There are also adaptive cruises that only pursue speed, regardless of fuel consumption, human drivers can slow down in advance to take a taxi, and accelerate can change gears in time.

The road conditions are good, the high-speed lane is dusty, and there are different speed limits, and the driving is orderly; The speed is fast, and there is a minimum speed limit at high speed, so the car can run; The driving is not bumpy, the road is smooth, and there will be no sudden interjection.

Because when running at high speeds, the engine will be at an optimal efficiency and the fuel consumption will be the lowest.

Because when running at high speeds, the speed is very uniform. There is no need to raise the grade, so the fuel consumption is the lowest.

Many car owners will also find that there is a strange phenomenon in the fuel consumption of the car when they usually drive, because many people will find that when they choose at the beginning, many netizens will often hear that it is more fuel-efficient if they choose to run at high speed. But what I didn't expect was that if you run at high speed in your daily life, your fuel consumption may be higher. Many people usually want to save fuel, so they choose to take the high speed or increase the speed as much as possible in the process of traveling.

Fuel consumption is increased to a certain extentIn this way, you can make your fuel consumption better, but in fact, it is the opposite. Many people will feel that if they start the car frequently in the city, it is very likely that they will increase the fuel consumption of their car to a certain extent, or when they encounter some traffic jams, they may also be very fuel-guzzling. And some cars may feel that they are driving faster when driving on the highway.

When driving, the speed of the car is relatively fast, so the fuel consumption may be relatively small, but in fact, the higher the speed of the car, the higher the fuel consumption, so for some car owners, they should also know the influence of some factors in this regard. Therefore, in daily life, you can have a better understanding of your car, or know under what circumstances your car has less fuel consumption. In fact, from the data point of view, the fuel consumption of some cars is actually affected by a certain degree of factors.

There is a certain degree of relationship with wind resistance, first of all, there is a certain degree of relationship with wind resistance, followed by the speed or the deflection force of the ground rotation, etc., these factors are all related to a certain extent. Therefore, when this friction is relatively large, the greater the resistance, and the greater the power consumption. In this case, the fuel consumption will become more, followed by a kind of rev, and every car will have an economy speed on its uh data.

If the fuel consumption is minimal, the speed is also different according to different models.

This problem is not universal, and it can be said that appropriate advice can be given to those who raise the issue. Under normal conditions, fuel consumption is reduced at high speeds, since the average speed is between 80 and 100. Lowest fuel consumption.
