My car started at a speed of 1,000, and the speed was still 1,000 after running dozens of kilometers

It is normal for the car to start the ignition and idle at a low speed of 1,000, and if it has been 1,000, it is recommended to consider cleaning up the carbon deposits.

Hello, the engine speed of 1000 rpm is relatively high when the car is hot, and the idle speed is normal at 800 rpm, which should be caused by carbon deposits.

Generally speaking, when you just start, the idle speed should be about 800 rpm, not more than 1,000 rpm, and the speed should be slowly increased when you accelerate slowly.

Hello, your normal idle speed must be a bit high, generally around 800, it may be caused by too much carbon deposition on the throttle!

Hello! In this case, it is mainly due to a problem with the engine's water temperature sensor, which is recommended to go to the repair shop to replace the engine's water temperature sensor.

Hello, you mean the idle speed of the engine, this is normal if it is an automatic car.

Hello, this needs to check whether the throttle is caused by too much carbon deposit, and this needs to be tested!

Hello, this cool car starts, the engine is normal at 1000 rpm, and it is still like this after driving so many miles, it is recommended to go to the repair shop to test it.

Hello, this needs to be cleaned by carbon deposition in the lower throttle, which is estimated to be caused by too much carbon deposition, and this needs to be focused on detection.

The speed of this cold car is normal, and the speed of 1000 rpm of the hot car is a bit high, can you refer to it?

It is normal to have 1,000 revolutions, and it is normal to idle within 2000 revolutions for cold start. In order to ensure the normal operation of the engine and quickly increase the water temperature of the engine, the car computer will control the fuel injector to increase the amount of fuel injected to increase the speed dissolution, as long as the water temperature of the engine rises, the speed will drop to normal.

Generally, after starting, it is not necessary to heat the car in situ to the normal water temperature before driving, as long as the in-situ hot car is 30-60 seconds, regardless of the speed of the engine, the real engine preheating is preheated in the car.

As long as the car can be driven at low speed (the engine speed is controlled below 2000, the speed is below 40km), the water temperature of the engine will quickly reach the normal temperature after driving for a while, and the water temperature of the engine can be driven according to the normal driving mode.

Engine speed

The speed of the engine is related to the number of work times per unit time or the effective power of the engine, that is, the effective power of the engine changes with the different speeds. Therefore, when indicating the effective power of the engine, its corresponding speed must also be indicated.

The effective power specified on the engine product label and its corresponding speed are called the rated power and the rated speed, respectively. The working condition of the engine at the rated power and rated speed is called the calibration condition. The rated power is not the maximum power that the engine can emit, it is the maximum effective power use limit formulated according to the use of the engine.

The nominal power value of the same type of engine is not the same when its use is different. The effective torque also varies with the engine condition. Therefore, the maximum torque that the automobile engine can output and its corresponding speed are used as an index to evaluate the engine dynamics.

The idle speed will increase when the cold car is started. In order to achieve the necessary conditions for combustion, the engine will require an increase in the concentration of the oil-gas mixture, so the engine will increase the idle speed to increase the amount of fuel injection and increase the concentration of the oil-gas mixture. However, when the engine reaches operating temperature, it will return to normal, and this increase in idle speed is not a fault.

The vehicle starts when it is cold, and the engine will run at high rpm in order to enter the state as soon as possible, commonly known as a hot car! If your car starts at less than 1000 rpm, you have to wait. If the rev speed drops again after a while, it means that the idle speed of your vehicle is too low and needs to be increased!

If you always keep the same rpm, it means that your car is in good condition before starting and does not need to be warmed up.

Car warm-up is the time to keep the car idle for about a minute after starting the car. Due to the long-term stationary state of the car, the oil in the engine of the car will slowly stop to the bottom of the engine, so there is no oil lubrication between the parts in the engine of the car.

The main reason for a hot car is that after the car is parked for a long time, the oil in the engine flows back into the oil pan in the lower part of the engine. Therefore, after ignition, the upper part of the engine is in a state of lack of lubrication without oil, and it is about 30 seconds after starting that the oil pump will be used to transport the oil to the pistons, connecting rods and crankshafts that need to be lubricated most in the engine.

Hello, it's not that every start must have a high idle speed is normal, the idle speed is automatically adjusted by the engine computer, it is affected by the outside water temperature, as well as the outside air temperature, not that every start must have a high number of revolutions.

Question: My car just started in the morning and revved below 1200 rpm.

Question: The car just bought very well, the idle speed of the cold car start is 1200 rpm, and the car has been used for 1 and a half years after this situation.

Question: After the car starts and walks for a period of time, when the car starts after the fire is stopped, the idle speed of the car can reach 1200 rpm again, and once it goes to 800 rpm, which is normal.

1. It is difficult to fire in the morning. It took a little longer to ignite, and I heard the engine get up and loosen again. 2. The engine of my car is also running at 1000 rpm after starting in the morning, and the idle speed of the car will reach about 700 after driving for a while.

If it's a manual transmission, it means that you haven't added gear, if it's an automatic transmission, it takes 2500 to 3000 to shift gears at the beginning, which is normal, if it takes 3000 rpm for 60 yards in normal driving, it means that there is a problem with the gearbox, or you are in the wrong gear and hung up to the low gear.

The speed of the car reaches 4000 rpm, only 50-60 yards of speed, like this case if it is a manual car, it must be the clutch plate is too worn, refueling time and space rotation slip, the speed of the car goes up, but it can't run, replacing the clutch pressure plate and clutch friction plate can solve the problem.

If it is an automatic wave car, it is a failure of the hydraulic rheostat or the oil circuit plate of the gearbox, the speed goes up, the gearbox does not jump gears or the torque is not enough, and the problem can be solved by overhauling the gearbox.

The speed of the car reaches 4000 rpm, only 50-60 yards of speed, like this case if it is a hand wave car, it must be the clutch plate is too worn, refueling time and space rotation slip, the speed of the car goes up, but it can't run, replace the clutch pressure plate and clutch friction plate can solve the problem; If it is an automatic wave car, it is a failure of the hydraulic rheostat or the oil circuit plate of the gearbox, the speed goes up, the gearbox does not jump gears or the torque is not enough, and the problem can be solved by overhauling the gearbox.

Yes, it's clear that something is wrong with the gearbox! Because the revs are high, but the transmission computer is not automatically upshifting. Resulting in high rpm and low gear, the speed of the car naturally cannot go up! Go check the gearbox now, and the gearbox computer! That's the problem.

It depends on whether it is in the automatic transmission or manual, manual: if you want to lower the gear, if the speed is high, it means that you should shift the gear automatically: see if you are instantaneous so high, and then still keep the speed without automatic upshifting.

If it's instantaneous, it's okay, if it's not upshifting, then try to release the throttle first, and then if you don't add gear, if it still doesn't, then you need to detect to determine if there is a problem with the vehicle.

Hello, winter, low temperature, Nissan car CVT transmission oil low temperature automatic protection function. At the beginning of the rpm increase, the speed of the car will be limited. Wait until the water temperature is normal before it becomes normal.

Generally, when this happens, after starting the engine, slow down for 3-5 minutes, and then it will be normal, if the ambient temperature is too low, then extend the slow time.

The same is true for my car, the clutch three-piece set that I just changed today.

There is a problem, if you use such a high speed for a long time, you will often pull the handbrake, which will increase the workload of the engine, make the engine wear out quickly, and consume very fuel.

There is no problem, but such behavior cannot be done for a long time, and it will affect the engine of the car in the long term.

There is no problem with running the speed of 7000 in gear for more than ten seconds, and the impact is not great, but it cannot be operated like this for a long time.

Summary. Hello, this is not normal, the speed reaches 100 km/h, the normal engine speed is between 2200 and 2500 rpm. When the engine reaches 5000 rpm, it means that the gearbox is faulty or the clutch is slipping, and this problem should be repaired in time to avoid serious slippage causing damage to the gearbox or clutch, and the vehicle will not be able to drive.

Transmission oil needs to be changed every 60,000 kilometers, and not changing oil for a long time will lead to abnormal wear and sound in the gearbox, which will eventually lead to transmission damage. It is advisable to use original oil, which can guarantee the life of the gearbox and the smoothness of shifting.

Hello, don't click to end, I'm textual to give you the full answer, 2-3 minutes.

Hello, this is not normal, the speed reaches 100 km/h, the normal engine speed is between 2200 and 2500 rpm. Changguanzhou engine reached 5000 rpm, indicating that the gearbox has a shield failure or the clutch has slippage, this problem should be repaired in time, so as not to cause serious slippage to cause damage to the gearbox or clutch, and the vehicle will not be able to drive. Transmission oil needs to be changed every 60,000 kilometers, and not changing oil for a long time will lead to abnormal wear and sound in the gearbox, which will eventually lead to transmission damage.

It is recommended to use the original hail oil, which can ensure the life of the gearbox and the smoothness of shifting.

Idle speed. The idle speed is about 1500 to 2000 rpm at the moment of cold start, and the idle speed is kept within the specified stable value after the engine water temperature returns to 90 degrees.

In order to avoid wear, when the engine computer detects that the engine temperature is relatively low, the computer will control and increase the idle speed, so that the engine can reach the working temperature as soon as possible, and when the engine reaches the working temperature, the computer will adjust the idle speed back to the normal number of revolutions.
