What are the consequences of running at a high speed and at a low speed, is it good to drive at a hi

High-end low-speed running, fuel-efficient, expensive maintenance in the later stage, I saw a lot of fuel-efficient posts, which are generally low-conversion gears, high-end low-speed driving, sought after by everyone, I found that the direction we pursue is wrong.

A long time ago, drivers would clean the throttle by themselves, and they were not afraid of oil and carbon deposits, but today's cars, after a problem, they are all replaced.

The consequences of oil scale and carbon deposits are: cold start, car shaking, and will destroy the car, driving acceleration weakness, meat.

How to solve: cleaning (hanging bottles) or unloading cleaning. The former is slow to act, the latter is fast. The cost of both is not small.

When the car is moving, it will produce oil scale and carbon deposits, but when running at high and low speed, the oil scale will leave more black oil in the oil pipe, valve, etc., which is caused by the low engine speed. The corresponding solution is: increase the number of revolutions of the gear shift ( When the cold car starts, when the water temperature does not reach the normal level, the gear shift should be kept below; In winter, it is better to use gasoline additives (each tank of oil, added before refueling).

Increasing the number of revolutions and shifting gears, and keeping the car behind, although it costs some oil, will keep the engine surging power, which is good for the engine.

Increasing the number of revolutions and keeping the car with the car can prevent the car from shaking and extinguishing the fire when the cold car starts.

If there is already a phenomenon of "cold car starting, shaking, extinguishing", please clean the throttle, etc., but change the driving habits after washing, or you can add gasoline additives to the car, and change the driving habits, the car will slowly get better.

In the usual driving, although it costs some oil, but it will keep the car in good condition, save the trouble of repairing the car, in the economic comprehensive calculation, you have earned, not only earned time, but also earned a good mood, the most important thing is that the engine maintains a surging power.

Don't blindly pursue low-shift, high-end and low-speed driving, that's scrapping cars! Remember, remember!

Mine, are you still satisfied?

A conclusive conclusion. High-grade and low-speed spark plugs are easy to break. The engine is easy to break at high speed and low gear. See for yourself.

Depending on whether you are willing to change a few spark plugs or the engine.

Hey.

The consequence is that your money is gone.

Thanks to the Baijiahao platform, I will share my car knowledge with you every day.

The disadvantages of high-end and low-speed driving of cars:

1. High-grade and low-speed driving of the car is easy to cause carbon deposition in the engine, and carbon deposition in the engine cylinder will make the car difficult to start, accelerate weakly, and consume fuel

2. It will cause the clutch to be damaged too quickly, and the gear ratio is not the normal proportion caused by high grade and low speed, and the sound of the gear "da-da" will be heard, at this time, the clutch gear will bear too much impact and cannot transmit the engine power normally, so the clutch is more likely to be damaged.

3. Long-term high-grade and low-speed driving, the clutch wears out too quickly, and it may also cause difficulties in gearing.

Many people think that high-end and low-speed will save fuel, let's make an assumption: if you use 5th gear.

At a speed of three or four kilometers per hour, from the perspective of engine speed, there are only more than 1,000 rpm, which is about the same as idle speed, and fuel saving is true. However, if you only drive for a short period of time, it will cost fuel and damage the engine if there is too much carbon in the engine cylinder. The final repair cost is much higher than the fuel savings, and the process can also cause clutch damage, which outweighs the cost.

Therefore, the car is not only a matter of fuel consumption, we should pay more attention to the maintenance of the car, and it is recommended that everyone drive correctly.

High-end and low-speed this driving habit is not good.

1.When the engine spring exacerbation is driving at high and low speeds, it is easy to form carbon deposits inside the engine. When the carbon deposit reaches a certain level, it will lead to problems such as difficulty in starting, increased fuel consumption, decreased engine power, and weak acceleration ability. In addition, the engine and clutch are severely worn.

2.The clutch is damaged too quickly, and due to high-grade and low-speed driving, the transmission ratio is not bright, and the "click" sound of the gear will be heard. At this time, the clutch gear will withstand too much impact and cannot transmit engine power normally, so the clutch is more likely to be damaged.

3.Excessive clutch wear out during long-term high-end and low-speed driving may also cause difficulty in shifting gears.

4.At high and low speeds, the engine works at critical speeds at high pressures. When the pressure exceeds this value, the engine will shut down, causing stalling.

Not good. High-end low speed means that the engine speed is too low. On the one hand, the engine shuddered, and the torque at low speed was insufficient.

It will lead to the acceleration of the inability to train and the other party, and the starting speed is too low, the ignition will not be sufficient, and the cylinder is prone to carbon deposit. Secondly, fuel efficiency is not high at low speeds.

Not good. First of all, it costs oil! The second cause of insufficient power shakes the whole car! Commonly known as: out of gear! It hurts the clutch!

The biggest disadvantage of low gear and high speed is that it costs fuel and the engine is noisy!

In the low gear, due to the gearbox gear ratio, the engine speed is very high, just like others run 60 highways at 2000 rpm, and 3500 rpm when running 60 highways in low gear. The increased fuel consumption varies according to the model and gear, there is no fixed number, but generally speaking, the low-end high-speed will increase the fuel consumption by 2 to 3 times, and the low-end high-speed and normal driving fuel consumption can be up to 12 ml, so the owner must drive correctly on the road.

Low and high speeds can lead to increased fuel consumption, high engine noise, and engine wear.

When the engine continues to run at high speed and increase the throttle to make the engine run at high speed when driving normally, and the mileage of the vehicle does not increase, then the fuel used for 100 kilometers will increase, and at the same time, the heat energy (power) of the engine running at high speed cannot be effectively converted into thrust to push the car forward.

This part of the heat energy is only collected by the coolant through the radiator and lost, causing the engine water temperature to be too high, which will cause damage to the engine in the long run and increase the wear of various parts of the engine.

Hazards of high speed and low gear:

1. Waste of gasoline;

2. Failure to fully utilize the kinetic energy of the car to make the engine run at high speed, and the gearbox runs at low gear. Suddenly hooking a high-speed car into a low gear will make the car run to drive the engine, and the sound will change, so it should not be used in operation.

3. This will cause a large amount of carbon deposits in the long run.

Hazards of low speed and high gear:

1. It is difficult to exert the full power of the engine when driving in high gear and low speed, and it will even cause damage to the power system of the vehicle.

2. When the engine works in the state of high gear and low speed, the engine output is weak and the torque is small. If you want to speed up, even if you try to refuel, it doesn't have the strength. As a result, a lot of oil was added, but the machine rotated very slowly, so it was not fuel-efficient.

3. Running in high gear and low speed for a long time, the engine often works near the critical speed, that is, it often works on the edge of stalling, the output power is not enough, and the gearbox cannot work normally, which has great damage to the gearbox.

4. It is difficult to give full play to the self-cleaning effect of the engine when working at low speed, and it is easy to produce carbon deposits in the engine and oil circuit, and finally it is easy to produce the failure of the engine and oil circuit.

Hello, this is still not recommended, low gear tells not only fuel consumption, but also has an impact on the car's engine and gearbox.

Hello, in this case, it is easy to cause the engine temperature to be too high, and at the same time, it will accelerate the wear of parts.

The impact of high gear and low speed on the car is as follows: 1. The high-speed and low-speed driving of the car is easy to cause carbon deposition in the engine, and the accumulation of carbon in the engine cylinder will make the car difficult to start, the acceleration is weak, and the phenomenon of fuel consumption occurs; 2. It will cause the clutch to be damaged too quickly, and the gear ratio will be abnormal due to high gear and low speed, and the gear "click" sound will be heard. 3. Driving at high gear and low speed during the long and simple wax period, the clutch wears out too quickly, which may also cause difficulties in gear mounting.

Thanks to the Baijiahao platform, I will share my car knowledge with you every day.

There are many car owners who think that in order to save fuel, they deliberately keep the engine speed very low, thinking that this can not only save fuel, but also reduce engine wear, but this practice is actually wrong.

First, the hazards of high grade and low speed

1. High-grade and low-speed driving is easy to form carbon deposits inside the engine, when the carbon deposits reach a certain extent, it will lead to the vehicle is difficult to start, fuel consumption increases, engine power decreases, acceleration weakness and other failures, the engine computer has a self-learning function, will remember this driving habit, and the car will be weak in the future.

2. Serious wear of the engine and clutch, poor transmission ratio of high-grade and low-speed driving, and easy engine shake. It is equivalent to the transmission braking, and the clutch is also subjected to huge friction, and the clutch slips when it is excessive, which aggravates wear. Therefore, high-grade and low-speed will not be fuel-efficient, and there will be ***, so you should pay attention to it during use.

Second, the hazards of low-grade and high-speed

The biggest disadvantage of low gear and high speed is that it costs fuel and the engine is noisy!

It's best to make good use of the gears! Especially during the new car break-in period! It is recommended to run 20 kilometers of high-speed (120) every 5000 kilometers to love the car!

3. Which is more harmful than low-grade high-speed or high-grade low-speed?

Compared with the two, of course, "high-grade and low-speed" is more harmful!

Many car owners believe that they deliberately keep engine speed low in order to save fuel. They believe that this will not only save fuel, but also reduce engine wear. Actually, this is not true.

First, the hazards of high grade and low speed.

1.High-grade and low-speed driving can easily lead to carbon deposits inside the engine. When carbon deposition reaches a certain level, it will lead to problems such as difficulty in starting the vehicle, increased fuel consumption, decreased engine power, and weak acceleration.

The engine computer has a self-learning function, which will remember this driving habit, and the vehicle will be weaker in the future.

2.The engine and clutch are seriously worn, and the transmission ratio of high-grade and low-speed driving is poor, and the engine shake is prone to occur. Equivalent to transmission braking, the clutch is also subjected to huge friction, which may cause clutch slippage, increased wear, etc.

Therefore, high-end and low-speed will not be fuel-efficient, there is ***, pay attention when using.

Second, the hazards of low grade and high speed.

The biggest disadvantage of low gear and high speed is high fuel consumption and high engine noise!

It's better to use the gears wisely! Especially during the run-in period of a new car! Also, it's not good to drive slowly. It is recommended to run 20 kilometers (120 kilometers) every 5000 kilometers, which is good for the car!

3. Which is more harmful, low-grade high-speed or high-grade low-speed?

Compared with the two, of course, it is "high-grade and low-speed" harmful!

Low gear fast driving will not save fuel, but will cause damage to the engine, whether it is low gear fast driving, or high gear and low speed driving, the engine will be destroyed for a long time, in the driving link must be frequent shifts.

The danger of low gear and fast to the car.

In the case of low-gear driving, the faster the speed, the higher the engine residual speed ratio, and the fuel consumption will be relatively high.

Can low gear eliminate carbon deposits quickly?

The effect of quickly eliminating carbon deposits in low gear is almost zero, this kind of method is mainly to increase the speed ratio of the engine, and then make the steam absorber destroy the cylinder to maintain a relatively large inlet working pressure and exhaust pipe working pressure, so that the number of methods can eliminate a little carbon deposit on the surface at most, but the vast majority of carbon deposits or more difficult to remove.

Damage in high and low gears.

1. Destruction of the power unit: When driving in high and low gears, the driving force of the engine cannot be fully utilized, and the power unit of the car will be destroyed;

2. Generate carbon deposits: driving in high gear and low speed gears, the engine is very easy to produce carbon deposits, and the accumulation of carbon deposits at a certain level will reduce the efficiency of the engine, resulting in the situation that the car is weak in speeding up;

3. Damage to the engine and clutch: Driving in high gear and low speed will cause the car's deceleration ratio to be poor, and the engine is very prone to flutter, which will aggravate the damage to the engine and clutch for a long time.

Millions of car purchase subsidies.
