Is the lower the engine speed, the better the car?

No, now for high-speed vehicles, the lower the speed, the better. After all, it represents a decent performance of the car. But these also need to have data to illustrate, controlling your car, it is good to be able to reach this number, in the normal range of more than 2000, usually between 2300 and 2500 rpm, this number can be called.

At low engine speeds, you can see that the engine is relatively smooth.

When driving normally, you may feel that when the speed reaches 120 kilometers per hour, regardless of the gear is almost the highest, you can identify the car by the engine speed. damaged, because the data shows that it does not lie, so the data will be different for different brands of cars, which causes the engine to run at the same speed, the gap is still large.

Today, shifters on the market are usually 6AT, 7-speed dual-clutch manual transmission, 8AT, 9AT or 5-speed manual transmission, and 6-speed manual transmission. Regardless of how the gearbox works, it must be lifted and operated. Once you're in low gear, the energy consumption will be small when you switch to high speed, and naturally, it will be more fuel-efficient.

Engine speed is the key to changing the gearbox. At the same speed, the torque is higher in the lowest gear, while the gear in the highest gear is faster. So, when driving at high speeds, you can drive your car, and the lower the speed, the better.

Summary; Regardless of whether the car is automatic or manual, the owner will drive with the accelerator and will not perform actions such as descent changes. At that time, different makes, models, rolling car brands, engines running at the same speed, the gap was still huge.

In a way, when you're driving a 120, the lower the rpm, the better. The transmission has a large adjustment range and low engine speed, and for those of us who drive, there is also a visible benefit of fuel economy. The comfort will also be very good if there are more gears, and the transmission ratio of the multi-gear gearbox is more dense, and it is very comfortable to drive and feel.

No matter which mode of conversion it is, once the speed of the gear is up, the power to switch to a high gear to maintain consumption will be small, and it will naturally be more fuel-efficient.

For those who have just started driving, this is indeed the case, and it is recommended to buy a car with a low engine speed.

Low rpm means that the transmission coefficient of the vehicle is not very high. The higher the rpm, the easier it is to change gears.

This is all from one side, and it is not necessarily good for a car with low revs.

This is still relative, and it must be controlled within a reasonable range to be the best.

In fact, this is not the case, but some cars are like this, generally speaking, the higher the speed, the higher the power.

The speed is low, the consumption is small, it can save fuel, and the machine is not wasted, but it should not be too low.

This is relative, depending on the car

In fact, this is not the case, the low speed of the engine indicates that the transmission performance of the car is average.

In the process of driving, the higher the speed of the engine, the better, because in this way, the driving speed will be better, and the quality of the engine is also very good, and it will not affect the follow-up.

In most cases, of course, the higher the speed, the better, indicating that the car has good performance. However, the low rpm of the family car is both fuel and car efficient, and the wear and tear of the car is much less.

It must be that the higher the better, and we will determine by the speed at which they operate, and their emissions are also relatively large, indicating that they are more skilled in this area, and they will become more and more proficient after use.

The higher the number of engines, the better, and the higher the engine, the more energetic it will be, and the wear and tear on the engine will be reduced.

In theory, low rpm means less fuel injection, which seems to save fuel. But if the gear remains the same, the lower the speed, the lower the fuel consumption, but the speed is very slow; The lower the engine speed, the more fuel-efficient? This problem can not be taken as ordered, this problem needs to have several conditions, such as the same vehicle and engine running at the same speed, then it must be the lower the speed, the more fuel-efficient, such as the same model, yes the engine, the speed is 100 kilometers, one is with a four-speed gearbox.

The engine revs at 3,100 rpm, one with a five-speed gearbox at 2,600 rpm and the other with a six-speed gearbox at 2,200 rpm.

<> which one do you think will get better fuel consumption? There is no doubt that 2200 rpm is more fuel-efficient, the lower the speed, the lower the oil carrying capacity, which is one of the reasons why there are more and more gearbox gears, because many gears can be larger than the gearbox, so the engine can use low speed to drive the vehicle, to achieve the purpose of reducing fuel consumption, the lower the speed. For the engine, the less fuel is injected, so it seems that the fuel consumption is lower, which is not the case for the vehicle, because the vehicle needs to overcome various drags, so the output power of the engine is taken into account.

The correspondence between the actual amount of fuel injected and the power.

For the performance of the engine, it is necessary to introduce the concept of the general characteristic curve of the engine, which is a calibration display of the engine characteristics, which more directly expresses the relationship between engine fuel consumption and power. But to be honest, OEMs generally don't give this curve to it, especially for the main engine currently in use, they don't have a way to get its common characteristic curve.

Do 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.

When the car is driving, it is not that the lower the engine speed, the more fuel-efficient, but the lower the fuel consumption when the power system conversion efficiency is higher.

Yes. This is because if the engine hand guesses that the speed chain is relatively low, it means that the fuel consumption is relatively low, so it is relatively fuel-efficient, but coasting with gear will damage the engine.

Yes, the lower the engine speed, the more fuel-efficient, and the fuel consumption will be particularly low when the car is kept at a constant speed.

Idle speed. It is not the reason for the low level, it is not the process of the machine itself becoming low, this is an artificial transfer, such as when the factory is very low, when you go to repair and maintenance, the repairer lowers.

Idle too low will occur in the carburetor.

If the concentration is too low, it will be easy to stall, and in serious cases, it will cause the exhaust pipe to discharge and not ignite (especially in winter), but if it is too high, the fuel consumption will be very high, and the exhaust pipe will also fire and emit black smoke.

Prolonged thick gas can also lead to spark plugs.

Carbon deposition makes it difficult to ignite, so the idle speed must be appropriate, generally speaking, the idle speed is slightly lower in summer and slightly higher in winter.

The idling speed of the car.

Not a speed, but a working condition. When the engine is idling, it is called idling. When the engine is running, if the accelerator pedal is completely relaxed, the engine is idling.

The idle speed can be adjusted by adjusting the damper size, etc. Generally speaking, the lowest idle speed is the lowest speed when the engine is not shaking. Idle speed too low is common in the following situations:

1. Failure of idle control valve, 2. Poor atomization or blockage of the injector.

3. Caused by changes in the viscosity of engine oil.

4. Through the crankshaft position sensor, etc.

It is recommended that you go to your local 4S store for an inspection to confirm the cause of this phenomenon, and if there is a fault, you should eliminate it in time.

If the speed is low when starting, you can adjust the idle motor, and if it is low after starting, it is recommended to clean the throttle again.

Hello landlord. Han Xiaoxuan will answer for you.

The throttle opening is not enough, the throttle is dirty, but it can be cleaned and then make a basic setting.

Idle motor Now the electric injection truck on the market idle motor will generally not have problems, except for vans (if the electric injection car idle motor is broken, you will generally be asked to replace the entire throttle The cost of the throttle is higher.)

3.Generally, you can't solve the problem of high or low car idling, so it is recommended that you go to the repair shop to check, or tell us more details.

Hope. Yours is our greatest encouragement.

It's all winter now! The temperature is low.

In terms of practicality, it must be a car with low speed and fast speed, which is more energy-efficient, quieter and smoother. For example, the high-speed gear of Magotan is at a speed of 100 yards, and the speed is less than 2000 rpm.

But the kind of sports car that pursues the limit is different, the Ferrari F430, at 3,000 rpm, is just 100 yards, and can break 300 km/h at 9,000 rpm. The engine on this sports car is high-revving, and at low revs the engine is mediocre, and once it exceeds 5,000 rpm, the power starts to explode until it reaches the red line.

The speed of the car engine must be reasonable according to the configuration of the vehicle to reach a certain suitable speed is the best, and not the higher the better, or the lower the better, so we must pay more attention to the use of the car engine.

There are many things to pay attention to in the use and maintenance of the car, so it is important to communicate with professional technicians and master the correct maintenance method of the car. Guess.

It is necessary to communicate with technical personnel and master the following aspects:

1. Smiling and mild-mannered.

Everyone likes to talk to someone who is smiling and soft-spoken, because they can hear a sense of intimacy in that person's speech. Do you feel comfortable when the person you're chatting with is smiling all the time? When his tone of voice makes you comfortable, do you feel the urge to continue talking to him?

2. Be polite in speech and behavior.

When talking to people, be sure to be mindful of what you say and do. As the so-called gentleman is polite, if you want to effectively communicate with others, you must learn to get along with others politely, so that others have a good impression of you!

3. Don't leave the same topic for too long.

Even if it's a topic that both people like, don't keep exchanging opinions on this topic, as it will bore the other person after a long time.

4. Don't talk about other people's sad things.

If you know that the other person has something bad recently, be sure not to mention it during the conversation, otherwise it will cause the other person to be disgusted and uncomfortable.

5. Find common ground.

The ancients said that if you don't speculate more than half a sentence, it means that in order to communicate effectively with people, you must find speculative people, that is, people who have a common topic. Therefore, the focus of effective communication with others is on common topics.
