What is the normal range of engine speed for a cold car in winter?

A: When the cold car starts, the engine speed is about 1000 rpm. When starting a cold car, the engine needs high rpm to warm up quickly and let the engine reach the basic temperature, so it is normal to say around 1000 rpm. Hope it helps!

When the car starts cold, it is normal for the engine speed to be around 1000 rpm.

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.

Normal pavement 1200 rpm start is more suitableIf you climb a hill or the vehicle load is large, you can increase the speed appropriately. In winter, it is best to warm up before starting, generally preheating for one minute, and the starting speed should not exceed 2000 rpm, which is not good for the engine.

The solution is very simple, put the car in a warm environment, and the ice can be started naturally. A complete solution can be to run at high speed in time, and the car will run more, and the heat from the exhaust will completely melt away the ice and expel it.

Reasons why the car won't start in winter:

Exhaust pipe freezing: the appearance is characterized by fog cylinder pressure, normal oil supply and power supply, and no car. This situation is easy to occur in the use of particularly low frequency of vehicles, such as the home is particularly close to the unit, the water vapor after the combustion of the engine freezes at the muffler of the exhaust pipe, the ice of yesterday is not finished after short-distance driving, and today's ice is frozen, and the time is long, affecting the exhaust, and it is serious and cannot be started.

Valve gelding: Winter vehicles, especially after the use of unclean gasoline, the non-combustible gum in the gasoline will accumulate near the intake, exhaust valves and combustion chambers, which will cause hard starting, or even no fire in the cold morning. Contingency Method:

You can drop some oil into the combustion chamber, and it can generally be started. After starting, go to the service station for dismantling and cleaning, and seriously dismantle the car for maintenance and cleaning of the cylinder head.

In winter, the engine speed is limited to no more than 3000 rpm, and it is normal to keep it at about 2000 rpm, otherwise the engine andGearboxThe intense wear and tear is irreversible.

The vehicle has just started, and if there is a high rev, it is what we call a cold start.

That is to say, the vehicle is turned off and parked for a period of time, and when it is started again, the engine is already in a cooled state and is not within the normal operating temperature.

In this case, the engine will increase its speed in order to get into normal operation as soon as possible. In the past, it was necessary to wait in place for a period of time after the engine of a vehicle starts from a cold and the speed drops and the water temperature rises before it can be driven on the road, a process called a hot car.

Basic concepts of engine characteristics:

1) Engine characteristics: refers to the relationship between engine performance indicators and changes with engine adjustment and operation.

2) Engine performance index: mainly power, torque, fuel consumption rate, effective thermal efficiency, exhaust temperature, exhaust smoke and other changes with the engine adjustment and operation of the relationship.

3) Engine adjustment: mainly refers to the diesel engine fuel supply advance angle and gasoline engine.

Ignition advance angle, mixture concentration, etc.

4) Engine operation: mainly refers to engine speed and load.

5) Engine characteristic curve: refers to the engine characteristics expressed in the form of curves.

The above content refers to Encyclopedia - Engine Speed Characteristics

Normal is generally 700-800 rpmIf the engine is too low, it is easy to shake, and if it is too high, the fuel consumption is high, as long as it does not shake, the design engineers want to try to reduce fuel as much as possible. In the following cases, the idle speed will automatically increase by 50-150**

1. Cold start, low water temperature;

2. The battery loses power.

The main advantage: 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 oil and lubrication, and it is only about 30 seconds after starting that the oil pump will be delivered to the pistons, connecting rods and crankshafts and other parts of the engine that need lubrication the most.

The hot car time is related to the uncertain factors such as the on-site temperature, vehicle condition, oil quality, etc., look at the engine speed, listen to the engine sound to determine whether you can start driving, listen to the sound needs to have a familiar process, or look at the speed is more intuitive, when the engine speed is stable at about 800 rpm, you can drive.

The best time to change gears is around 2000 rpm.

Idle for 2-5 minutes, then drive around 20kmh, and you can drive normally after the water temperature is normal. Of course, if you're not in a hurry, it's better to let the car idle to a normal water temperature. It should be noted that if it is an engine with a supercharger, do not idle for too long, as it is prone to slight leakage.

It is best not to exceed 1500, walk slowly for a while, slowly increase the speed and wait for the water temperature to reach the middle position in normal driving.

In winter, the starting point should not exceed 2,000 rpm, and generally 1,500 rpm is sufficient---

In winter, the main thing is to warm up the car, and after the heat is fully warmed up, it is the same as normal driving.

Hello owner, that's because the oil has not gone up, it is recommended to check the oil pump, oil filter, whether the oil should be changed, I hope my answer to your problem Thank you for your support, I wish you a happy car.

It is normal for the car to start at a high speed, generally speaking, the engine can often reach 1200-1500 rpm at the moment of starting, if it is in the cold season, the engine speed will be higher, because the speed is too low The vehicle will turn off, and a little higher can heat up the car as soon as possible. However, when starting cold, the speed should not be too high, because the lubricating oil can not reach the upper part of the engine, in order to reduce wear, it is more appropriate to do less than 2000 rpm, and when the engine condition is stable, the engine speed will drop to about 800 rpm.

Therefore, it is normal for the starting speed to be a little higher, and the starting speed of the general family car is about 1000-1500, which will vary from model to model, and now many manufacturers are deliberately adjusting the starting speed to be higher, so that the vehicle has enough power after the gear.

Many car owners are concerned about the speed of the car, especially now that there are more and more automatic transmissions, the gears are automatically controlled by the engine, in addition to paying attention to fuel consumption and speed, it seems that there is no need to worry about the speed. However, the speed can always reflect the working condition of the engine, if the speed is too low, the fuel is not fully burned in the cylinder, the engine is easy to produce carbon deposits, and the damage to the engine is quite large for a long time. If the revs are too high, it will also cause more wear on the engine.

It varies according to a vehicle type and ambient temperature. 1000-1400 rpm.

There is a high idle process after the cold start, especially in winter, which is a phenomenon caused by the on-board computer control (electronic throttle control system vehicle), when the engine reaches a certain temperature, the idle speed will be normal. This can help to accelerate the engine temperature to normal working conditions during cold start.

In addition, there may be a slight abnormal noise in the engine when the cold car starts, such as the abnormal noise disappears after a few minutes of hot driving, which does not affect the driving of the vehicle. Because after the vehicle is parked overnight, the oil of each part of the engine has flowed back into the oil pan, so it is best to warm up the car for a few minutes when starting in the morning, because one of the reasons is to let the oil supply to each component, and the other is to make the temperature of the engine rise to make it work better; And when the vehicle is started, the generator is in a fast charging state, at this time, it is normal to have a louder noise.

Hello, it is normal for the car to start the engine at about 1200 rpm when the car is cold, and it is normal to return to about 800 rpm at idle speed after the hot car, I hope it will help you, I wish you a happy drive.

Under normal circumstances, it is normal for the vehicle to have an engine speed of about 800 to 1000 rpm when the vehicle is started cold.

Generally speaking, when the cold car starts, the engine speed should be controlled at about 800 to 1000, which is more reasonable.

Hello, when this cool car starts, its idle speed should be around 800 to 1000 rpm, you can refer to it.

Hello! The moment the vehicle starts cold, the engine speed should be around 1500 rpm. As the temperature rises, the engine idle speed gradually decreases.

Hello, it's cold now, and the speed of the cool car is generally around 1000 rpm when it starts. After the car is hot, it falls to seven or eight hundred revolutions.

Hello, it is generally normal for the engine to rotate at about 1000 rpm when the cold car is started.

Hello! For different models, the speed after the cold start is also different, generally around 1200 is normal, if the speed is too low or too high, there is a problem.

Hello, the idle speed of the cold car is controlled by the engine computer according to the water temperature, generally about 1,000 rpm, about two minutes, after the normal temperature of the car, the idle speed is normal, I am happy to answer for you!

If the vehicle is normally cold and starts, the ignition will be around 100 rpm, and then slowly drop to 800, and the water temperature will slowly rise.

Hello! The vehicle needs to be warmed up, and the engine can be driven below 1000 rpm normally without any problems.

The cold start speed of the car is generally 800 to 1000 is normal: 1. The starting idle speed is that the car does not give oil when it starts, and directly lifts the clutch slowly to achieve the purpose of starting. You can bring a little bit; 2. In the colder morning, the car is to warm up, and the colder the day, the longer it takes.

So in order to be faster, the acute person pulls the throttle hard, or temporarily increases the idling speed. This is indeed much faster, but at this time, because the cylinder block is too cold, some gasoline droplets attached to the cylinder wall dilute the oil on the cylinder wall, making the oil film formed between the piston and the cylinder wall thinner; 3. At the same time, the excessively high speed aggravates the friction. At the same time, it should be noted that the fuel supply at idle is very thick, and the atomization of gasoline is very poor, which also promotes the formation of larger droplets.

In the long run, it is only a matter of time before the engine oil burns.

Summary. Hello dear! We are glad to answer for you, when the engine is started cold, the normal speed is around 1200 rpm.

When the car engine starts cold, the speed of the engine is higher than that of normal operation, and the specific value of this speed has a certain relationship with the water temperature of the engine, the lower the temperature of the engine, the higher the speed of the engine. Because the engine needs to be warmed up as soon as possible during cold start, the engine computer will control the engine speed increase to achieve a faster warm-up speed. When the normal engine water temperature reaches about 60, the engine can return to the normal idle state.

Looking forward to seeing you again! Have a great day! <>

<> my Toyota Yize cold car next to the starting beam to the Rubber Grip Oak 1700 over a bit loud. After 10 years, the picosecond slowly dropped to normal What's going on, and the oil is about to be changed, is it related to the oil or the engine.

Like the model of Toyota Yize, the idle speed of the cold car is indeed more Gaosen, if the sound is also very loud, this has a specific relationship with your engine oil, and the sound will become smaller after changing the oil.

In this case, you will have a significant improvement after changing the oil, but this speed will not change much, because the idle speed of the cold car is relatively high.

Is it normal?

Yes, like the speed of the cold car at 1700 rpm, this is the oak and silver of the seepage, but the noise is a bit loud, this has something to do with your oil, and the noise will become less after changing the new oil.

Okay thank you. Is the starting speed of the cold car relatively high, and the throttle is dirty, isn't it still like this model itself, but the car is very good when it is lowered.

Like this model, the speed is relatively high when the cold car starts, which has nothing to do with the carbon deposition of the throttle, if the throttle has carbon deposits, it will only cause the engine idle speed to be too low, and it will not be too high, so you are normal, don't worry.

How is this engine?

Like the Toyota Yize engine, the overall performance is still relatively stable, like this engine is a self-kai sucked configuration Yinsun is missing, so there is no problem in the later stage.
