What is the reason why the water temperature gauge flashes in the morning and the engine tachometer

The main reasons are:

1. If it is a mechanical tachometer, it may be that the transmission core is broken, and the solution is to replace the transmission core.

2. There is also a possibility that there is a foreign body stuck in the table and cannot be moved, so you can open the table to remove the foreign body.

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, in stating the size of the effective power of the engine.

, the corresponding rotational 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 under the rated power and rated speed is called.

Calibration conditions. 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 rated power of the same type of engine when its use is different.

The values are not the same. 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.

Hello, it's a problem with the engine computer board, and it is recommended that you go to the repair shop to check it. [If you have a problem with the car, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

There are several reasons why the water temperature gauge does not move when the car starts:

1. The water temperature sensor of the car is faulty or aging, or it may be that the water temperature sensor plug is faulty;

2. There is a problem with the line or the water temperature meter pointer itself is faulty, which will cause the water temperature meter to not move;

3. If this problem occurs, it is recommended to go to the auto repair shop, use the on-board computer to detect it, test the engine system, read the fault code, check the dynamic parameters, and do component testing, which can accurately find the problem and then solve the problem.

If the water temperature meter does not move, it may be caused by a malfunction of the water temperature sensor, and it is recommended that riders replace the water temperature sensor. Car engines.

All are water-cooled, and this engine relies on coolant.

Excess heat is continuously circulated in the engine. The coolant has two circulation paths within the engine, one is the large circulation.

The other is a small loop.

When the engine is first started, the engine has not yet reached its normal operating temperature, and the coolant is circulated in the engine for a small time. Coolant.

If the water temperature meter does not move, the water temperature sensor is faulty, and it is recommended that the owner replace the water temperature sensor. Automobile engines are water-cooled, and this type of engine relies on coolant to continuously circulate in the engine to remove excess heat. The coolant has two circulation paths within the engine, one is a large cycle and the other is a small cycle.

When the engine is first started, the engine has not yet reached its normal operating temperature, and the coolant is circulated in the engine for a small time. Knowledge of car water temperature: Under normal circumstances, the car's water temperature gauge scale pointer will change with the change of water temperature.

When the vehicle is first started, the water temperature is generally very low, especially in winter, and the car should be warmed up first. After starting the car, the final thing to do is to see if the water temperature is normal.

When the car starts, the indicators of many sensors will light up and can be seen on the dashboard. These Bunayama lamps turn off after a few seconds, which is a kind of self-check. The water temperature gauge will be like this when the normal cold car starts, and it will disappear when the car is hot after driving for a while.

But if it doesn't disappear for a long time, go to a 4S store to check it out.

The correct way to warm up the car is to start the road 30 seconds to one minute after the start type. However, at this time, do not drive at high speeds, keep the speed at a low speed, and the engine speed should not exceed 3000 3500 rpm. Generally keep 2000 rpm.

Otherwise, the intense wear and tear on the engine and Minyan gearbox will not be restored. Wait for the engine temperature to rise to normal operating temperature before resuming"Personal habits"The driving method is sufficient.

2.Warm up cars are needed in both summer and winter, and the warm-up time in winter is longer than in summer. After a night of static use of the engine, the lubricating oil on each friction surface has basically disappeared, and the oil film protection has been lost; The low temperature increases the viscosity of the lubricant, resulting in poor adhesion and flowability, which increases the resistance of the engine when it starts.

Driving at this time will increase the load on the engine and increase unnecessary wear. Studies by authoritative institutions have shown that the amount of wear and tear of the engine during cold start accounts for about half of the total wear. Normal idle warm-up can reduce this wear and tear, which can extend the life of the engine.

At low temperatures, the metal will show less elasticity and wear resistance, and only at normal operating temperatures can the engine achieve normal mating clearance and maintain optimal working condition.

If the water temperature meter is suffocated, it may be caused by the failure of the water temperature sensor, it is recommended that the car friends to replace the water temperature sensor, the car engine is the water ant is hungry and cold limbs guess, this engine relies on coolant in the engine to continuously circulate to take away excess heat,

Hehe, this car friend is really careful, and most people really pay little attention to this aspect, I think your car must be very well maintained. The phenomenon you are talking about is normal, so the engine temperature has not yet risen, and the coolant and water temperature are still cooling. The pointer on the water temperature meter is based on the temperature judgment sensed by the water temperature sensor (mainly to detect the temperature of the water) and transmits it to the driver in the form of a pointer, so that the driver can understand the temperature of the car.

Hope the above can help you.

Summary. Hello, I am happy to answer your car master exclusive technician to answer your car questions sincerely and sincerely for you, and find solutions and methods for you to ask questions. After driving for a long time, the engine fault light lights up and the water temperature gauge does not move, which may be caused by the virtual connection of the water temperature sensor and related wiring.
