Open the workshop and step on the accelerator intermittently, can this achieve fuel saving?

Similar to the brake point pedal.

Unless the road is very stable, the wind is also small, the duration of the suspension of fuel can reach more than ten or twenty seconds, this is not fuel-efficient, first of all, you have to know the car in what case the most fuel-efficient, is the most fuel-efficient in the case of constant speed, this is why the urban traffic jam car fuel consumption is very high, anyway, the fuel consumption is very low when going at high speed.

For example, when walking in the city, traffic jam + traffic light with one foot of accelerator and one foot of brake, fuel consumption will be much higher than usual, which can be regarded as intermittent throttle, right? And when driving at high speeds, the throttle is stable in one state, so it is very fuel-efficient.

If you deliberately go to save fuel, you should pay attention to the following points when driving:

1. Use the inertia of the car, slow down the acceleration, don't step on the accelerator with a big foot, use the gear brake more, and step on the brake less.

Bigfoot throttle and big foot brake will not only increase fuel consumption, but also cause great wear and tear on the engine and braking system, the criterion is: make the car full of power, but the speed is not too high.

2. Control the speed of the vehicle.

Because the size and displacement of the car are different, there is no unified speed standard, but in the experience and data of driving at high speed, most of the vehicles at 60-80km h are the most fuel-efficient, if the speed is too low, it will lead to insufficient fuel, and too fast will increase the wind resistance, so fuel consumption will also rise.

3. Wait for the red light.

The traffic light within 20 seconds can keep stepping on the brakes to avoid the impact of shifting gears on the engine, and people are more labor-saving.

The car is a consumable, it will inevitably bring consumption, and it is not necessary to deliberately save fuel to drive, you will find that the fuel saving and non-fuel saving driving method is not much different, so how to drive it, if you really care about the fuel money, it is better to take public transportation.

It won't work. Because this way of stepping on the throttle will make the revs unstable, so it will not save fuel.

Unless the road is very stable and the wind is light, the duration of the suspension of fuel can reach more than ten or twenty seconds, which will not save fuel.

Here, what we need to know is,The gasoline of the vehicle is transported through an oil pump placed in the fuel tank, enters the oil pipe and reaches the engine for combustion. This is responsible for the gasoline "sucking out" and the oil pump needs to be soaked in gasoline for heat dissipation and lubrication. Many veteran drivers advise you not to wait until the fuel tank light is on to refuel, because they are worried that there is not much gasoline left in the tank and cannot cool the oil pump well, causing damage to the parts.

Although the gasoline level is low when the tank light is on, the tank level of the oil pump is still high. In this case, it won't have much of an impact on the lubrication and heat dissipation of the oil pump, so don't worry too much.

Very bad for the oil pump. The light is lit only when the sensor on the oil pump is unable to contact the gasoline. In this way, it is very unfavorable to the oil pump for a long time and will shorten the service life of the oil pump.

When the oil pump is almost exhausted, the oil pump cannot be soaked in oil, its temperature will rise, and it will burn easily. The fuel pump is soaked in the fuel to work, that is, the fuel is cooled to the oil pump, if the oil level is too low, or the fuel tank is basically oil-free, then the car continues to run, at this time the oil pump can not dissipate heat, it will cause high temperature damage to the oil pump, if it runs often, the oil pump will retire early, the income is greater than the loss, it is recommended to generally leave 2 grids, or the oil lamp just turned on to refuel, do not continue to run a long-distance sports car!

First of all, the car has been in a state of low fuel for a long time, and the damage to the car is still relatively large. Although it is now an electric injection engine, the fuel pump is located at the bottom of the tank, and the fuel pump housing is not directly involved in heat dissipation, so the more oil, the less oil, and the fuel pump is not immersed in the oil, which has no effect on the heat dissipation of the fuel pump. Due to the current fuel pump, its heat dissipation mainly relies on fuel suction and injection, and this suction - by the way, the heat on the fuel pump can be carried away during the spraying process.

In other words, as long as the fuel pump suction and supply oil normally, there is no problem with heat dissipation.

When the gasoline oil is too low, first of all, the fuel pump itself is fixed, and then the car will also bum, so once the fuel is too low, coupled with very severe bumps, it may cause several mouthfuls of oil to not be absorbed, which is often referred to as fuel pump idling. The gasoline level in the fuel tank is too low, and the fuel pump idles for a long time, which will cause relatively large damage to the oil pump, and the severity will even burn or burn the pump body. Secondly, some cities may not have a very reasonable planning of gas stations, so car owners can not have a fluke mentality, want to run a little, oil is always added, you drag if you forget or can't find the next gas station, the car lying on the road is very interesting.

When the oil light is too low, the temperature of the fuel tank will rise a lot, causing gasoline to evaporate, so that the actual oil light is lower than the amount on the dashboard, and driving with low fuel consumption will be more fuel-efficient. Due to the evaporation of gasoline, it will also permeate into all parts of the car, and when it condenses again, it will seriously affect the normal operation of the car.

If the car runs out of fuel before refueling, it will lead to insufficient fuel supply to the engine, affect the operation of the engine, reduce the life of the engine, lead to the evaporation of gasoline, permeate the internal parts of the car, and affect the normal driving of the vehicle.

In this way, the oil pump basically has no way to dissipate heat, especially easy to fail, it may burn the oil pump, and if it is serious, it will affect our safety, and there may be no way to continue driving because it cannot reach the gas station in time.

I think of course you can, because when you don't step on the accelerator, the engine injects less fuel, so you save fuel.

No, this will not only reduce the life of the car, but also increase fuel consumption. This is a misconception.

I don't think so, because now it's all EFI trucks, and as long as it doesn't turn off, it will always spray fuel.

When we drive, whether it is a manual car or an automatic car, driving experience and handling are on the one hand, and the fuel economy of car driving operation is on the other hand, some drivers who have driven a car for five years or ten years are self-righteous old drivers, and they know enough about the car, and many old drivers will think that intermittent stepping on the accelerator is fuel economy. Not really! Speaking of intermittent throttle pressing, let's first understand what intermittent throttle pedaling is.

<>For example, when the manual transmission car enters any gear, we step on the accelerator to the end, increase the engine speed to a lot, and then completely release the accelerator, the car relies on inertia in the case of sliding with gear, when the speed is lowered and then step on the accelerator deeply, so that repeatedly stepping on the accelerator, putting the accelerator, and coasting with gear is called intermittent stepping on the accelerator.

Many veteran drivers believe that coasting in gear does not consume fuel, and the engine runs more efficiently when the car accelerates, which should be more fuel-efficient than driving at a constant speed. Is this really the case?

The accelerator pedal can indeed improve the operating efficiency of the engine, but this high-efficiency range, the driver will not grasp it well, because in the actual driving process, the amount of fuel injection and air intake in the acceleration phase is difficult to control, and the air that may actually need to be inhaled when it is perfect is very different from the air inhaled now, and the amount of fuel injected has also decreased a lot; If the engine does not reach perfect instantaneous operating conditions, there is no fuel economy.

When we step on the accelerator with one foot deep and one foot shallow, when the car slides in gear, we cannot accurately control the full throttle time and coasting time, and the engine will not save fuel.

Summary: There are actually many ways to save fuel when driving, including minimizing braking, reducing idling, avoiding traffic jams, reducing rapid acceleration, and driving at a constant speed as much as possible to save fuel.

The above is a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

The car is the most fuel-intensive at the moment when you step on the accelerator, so the indirect stepping on the accelerator will not only not save fuel but will consume more fuel, and the indirect stepping on the accelerator is to release the accelerator when the speed is high, and accelerate when the speed is slow, so that the car has been in the situation of refueling, so the fuel consumption will naturally be much higher.

There is no such thing as fuel saving, just a simple example, have you ever seen that it is more fuel-efficient when you are stuck in traffic, no? It is obvious that the car will only save fuel when it is driving at a constant speed, and there is no fuel saving when the speed is fast and slow.

It certainly won't be fuel-efficient.

Old drivers often say that indirect stepping on the accelerator can save fuel, but in fact, this statement is aimed at some special situations. If there is a wind or a slight press of the accelerator when going downhill, the throttle can be cleared, and the vehicle will enter a coasting state, which may be fuel-efficient.

Generally, when the car is in a coasting state, the engine is running slowly at idle speed, and the fuel consumption at this time is relatively small, if the acceleration time is particularly short, the fuel consumed by the car key finger at this time will be less, and the total fuel consumed when accelerating or coasting is less than the fuel consumed by driving at the same speed. It can be found that the indirect gas pedal closes the door, this operation has some similarities with the theory that it can achieve fuel saving, but in the process of driving the car, it is generally a foot on the accelerator, and the speed will be increased at this time.

After releasing the throttle, it will still run between high speeds, and it is not possible to fully control which zone the engine is running efficiently. If you want to control the fuel consumption of the car at this stage of starting, you need to pay attention to it, when the start accelerates, the movement state of the vehicle is stationary at this time, and the body has no inertia, at this time, you need to rely on the engine to directly stretch the speed, but also to improve the output power. Fuel consumption may increase at high speeds, and instantaneous fuel consumption may also reach certain values in the process.

After the car decelerates, you choose to accelerate, which will have the assistance of inertia, the valve effect, the car decelerates and the resistance will be greater, and the engine power will be greater than the resistance when accelerating, so the way to pull up the power still needs to be controlled by pulling up the speed, which is more fuel-efficient during the driving process of the car. In the process of sliding, you can use the mode of coasting with gear to achieve zero fuel injection, if the distance of sliding is not particularly long or take the downhill road, so the fuel consumption will be more for a long time in sliding, so the safety of driving should be considered.

This method is also based on the fact that if you step on the accelerator indirectly, you can use the inertia of the car to drive, but this method is only suitable for old drivers.

It also depends on whether it is on the highway or in the downtown area, if the noise is driving in the urban area, you will often encounter traffic jams or traffic lights, stop-and-go is a common thing, and the fuel consumption will be higher than that of the flat sail, which is similar to the intermittent stepping on the accelerator. The high-speed highway driving is different, unless there is a special traffic jam in Luchang, it is generally driven at a constant speed, which will save a little fuel.

Yes. Because intermittently stepping on the accelerator can take advantage of the car's inertia to move forward, which can save energy to a large extent, there is a basis for this method.

Many people find that many drivers often step on and release the accelerator when driving a sock-shirt car, which makes many novice drivers feel very strange. As a result, many novice drivers are asking, is the throttle often pressed or released to save fuel, or is the technology backward? Or is this how these old drivers operate?

The first reason is that the driver's operating skills are really not very good. It is likely that the driver has just gotten his license, so he doesn't have good control over the vehicle's throttle. As a result, while driving, the throttle is often depressed and released.

This throttle is often pressed and released, which can make the passengers sitting in the back seat feel very uncomfortable, and the driver himself can easily feel driving fatigue.

The second reason is that the driver is there to save fuel, not to have poor driving skills. Unlike drivers with poor driving skills, this type of driver doesn't feel particularly frustrated when they step on and release the throttle, so they sit in the car and the passengers don't feel particularly uncomfortable. The reason why these drivers step on and release the throttle is mainly to use the vehicle's inertia to propel the vehicle forward.

This way, they can really save fuel. At the same time, if you notice that the speed has slowed down, you can fill up the throttle. When I'm driving, I have an instant gas consumption display on my car.

I would find that as soon as I retract the throttle a little bit and stabilize the throttle, the instantaneous fuel consumption is immediately reduced. As for why the instantaneous fuel consumption is immediately reduced when the throttle is slightly retracted and then stabilized, the main reason is that the vehicle's ECU is able to intelligently judge the vehicle's idea map and default to the driver's desire to slow down. In this way, the ECU will control the vehicle and automatically shorten the fuel injection pulse width, thus saving fuel consumption.

The third reason is to advance ** and control the speed with the throttle. For example, while driving normally, I noticed that a car in front of me was turning a corner, so I released the throttle and the car started to slow down gradually. When it got close to the front of the collapse, the car in front had just turned around and gave way to the lane, so I stepped on the gas pedal and continued driving.

When the throttle is released, the engine stops the fuel injection, the drive wheels pull the engine in reverse to rotate, the engine is blocked, and the force reduces the rev instead of braking. Once the vehicle in front of you has given way to the lane, tap the accelerator and continue driving. In the process, if the distance is right, there is no need to press the brakes and it is more fuel-efficient.

The skill of low average fuel consumption of veteran drivers is essential.
